I have a friend that owns a pair of B&W loudspeakers costing $15,000. Currently he is living in a house and having a house built. I've suggested that he should take advantage of making adjustments during construction that will have positive effects on his final listening experience. I'm not sure it is resonating with him. Of course he doesn't have 15+ years in recording, mastering and acoustics. I told spending a large sum of money on some impressive speakers doesn't guarantee any sound quality in a poorly designed. He might be better off with a pair of Radio Shack Minimus 7's and a subwoofer. In my opinion, people totally misunderstand how important the room acoustics play in the overall objective. I found your video very compelling. Thanks!

[@rotorfix]

One of my best experiences in HiFi was purchasing speakers from Clayton. He's a gentleman and absolute pleasure to do business with. It was evident that he believes in the unparalleled value of his products and is not out to make the quick buck.

[@evansstudios]

Agreed. I called him last week to discuss the M3 and X5, to see which would be a better fit and he took the time to answer all my questions and chat about my room, electronics and listening preferences. Can't wait to take delivery of my X5s

[@blessonjacob3809]

Jon Evans would you be able to share a summary of the pros and cons of both models? I’m debating between these two models as well.

[@evansstudios]

@@blessonjacob3809 Sure, but he does touch on most of it in this video. First a little background; my room is about twice as long as it is wide, and it opens up on the side in the back to another room then on to the kitchen/family room area. It also has a wide opening to a hallway on the same side. The regular listening position is a sofa that's about 8ft from the speakers and right behind the sofa is a large freestanding bookshelf that acts as a room divider. Behind this is my desk and office space, which is where I am most of time while listening. That or I'm wandering around the other rooms and the kitchen. Here are some of the deciding factors that made the X5 the choice over the M3 for me: The powered woofers and better efficiency: I have a couple low power tube amps I like to use, specifically a < 2wpc 45 SET. With the X series, my amps are only driving the mid range and tweeter. The powered woofer on the X5 also plays down lower than the M3, Clayton mentioned he's seen it go down to 20hz depending on the room, which will allow me to get rid of my subs and simplify my setup. The powered subs in the X series also make it a true 3 way design, vs the M which is more of a 2 way speaker. The tweeter: The AMT is more focused and will perform better at longer distances. I'm almost never sitting in the listening position, I'm either at my desk in the back of the room or in an adjacent room. Dynamics: The X series was designed to be more dynamic which will lend itself better to my preferred genres. I got three words for you. Punk. Rock. Metal. Finally aesthetics, and this is just my opinion, but I like the way the ultralam material on the X5 looks, I prefer it to the M series veneers. Note that the photos on his site don't do it any justice, it looks completely different, especially close up. I also prefer the metal supports on the X. All that being said, if I spent most of my time closer, in the listening position, and I was running a higher power amp most of the time, I'd give more consideration to the M3 paired with subs. Hope that helps.

[@blessonjacob3809]

Jon Evans really appreciate you taking out time to share!

[@evansstudios]

@@blessonjacob3809 Sure man, glad to help. Clayton did another interview posted on the LTA channel where he discusses the differences a bit. kzbin.info/www/bejne/rIqrm4GZaNCKd7M

[@karlcotleanu4144]

Man, I only intended to check out the first two or three minutes of this video, but I ended up watching the whole damn thing. Fascinating stuff!! All my OB questions and confusions answered. I have never listened to OB speakers, but I now know why I would absolutely love them. Thank you very much for this amazingly informative Q & A session.

[@dmgmail7021]

I called Spatial Ausio on some random day and Clayton spent over an hour with me on the phone. We talked about all parts of a system. Infact more about approach and philosophy and my equipment than he even did his speakers. And he was very complimentary towards my speakers and never tried to sell me. I wish the rest of the industry would approach their customers this way. If I ever decide to part with my speakers (which I still truly love) I would definitely consider SA before anything else. I really didn't want to move off my speakers but this design really interests me. And whats really apparent is how these speakers reflect Clayton Shaws musical reproduction philosophy so your not just buying another speaker similar to everything else on the market, your buying into something someone us trying to break thru with something different and revolutionary. Anyways that's how I felt after our conversation.

[@vse0]

My Linkwitz (Rest in peace you GOD you !!) Orions were the best speakers i have ever heard!!!!! we will miss you Sir!

[@Scottlp2]

Any idea how they sounded vs today’s open baffles? Perhaps one can still get linkwitz’s made (though not by him obviously)

[@nickreecy4229]

My search for speaker contentment ended when I picked up my Spatial M4s. Have had them for two years and I haven't desired anything else. Clayton is great as well, always very kind and helpful.

[@polylight]

Wish you guys success. I was so lucky to attend a Linkwitz open house demo a couple years before he passed away. Since I was already a woodworker, a pair of LX-531's was easy for me to make, but I never would have dropped that money on the raw materials and electronics had I not heard them first. So happy now...I had spent 2+ decades in frustration in never having enough money to afford a pair of B&W's I wanted (especially with them doubling the prices every 5-10 years). Now I don't care what B&W or the other big boys make, the dipoles truly have satisfied me for life.

[@jorgebacani1901]

i also built the LX521. there’s no way i’m going back to boxed speakers.

[@Nihil1st1347]

Long ago I had me build an open baffle sub using 2 opposing 12" Audax chassis on the proposal of Sigfried Linkwitz to support my electrostatic LS. The sub was driven by an old Technics amp and separated by an active x-over at 12 dB, 120 Hz. They used to play fine. Only after a while the electrostatics wore out and I had to repair them. Becoming part of the DIY community was overwhelming. I got very friendly help cutting out the round holes.

[@stephenscharf6293]

Great interview with Clayton. I found this interview to be very interesting and informative, thanks so much, Ron!

[@512bb]

Great discussion & I have much respect for Clayton. The room is the biggest & most unfun issue to deal with that most of us never get completely worked out, open baffle deffinatly makes the journey easier. You also make it easy to see why many choose to go the headphone route & completely eliminate the problem all together.

[@duythai5442]

Problem one is room. Problem two is room. Clayton knows his stuff. Thank you for the interview.

[@carlos2bass]

Great that Spatial audio is doing a great job promoting and making open baffle speakers right now; we also need to recognize the recently descease Jorma Salmi of Gradient speakers in Finland who introduced open baffle in the early 90,s.His sub system for the Quads and his Gradient Revolution are classic models that were highly recognized 30 years ago.

[@bujoun76]

Thanks Ron! You gave "the man" himself my question. I don't blame you for skipping over my handle...

[@jeffsloane8628]

Clayton is a class act individual who lets his research and products speak for them selves. When there is less BS, there is less to have to dance around. I watched the whole video and he was seated the whole time. :-) Can't wait to hear a set of Spatial speakers. Thanks for another good one Ron.

[@Newrecordday2013]

I agree with every word you just said.

[@markwagner1997]

I can't believe I watched tha whole thing! GREAT interview and dive into the Spatial speakers. Thanks Ron and Clayton!

[@StewartMarkley]

Open baffle speakers don't cure room issues but do offer some additional options to room treatments and positioning. The main advantage with open baffles I think is that they are better with transient sounds than sealed or even more so ported speakers as there is less stored energy involved to start and stop because there is no trapped air that has resonances with reactances that can smear the transients. This is also why horns and planar speakers have advantages over the common box speaker because they can react quicker to music transients. The best transient performing speakers today are planar magnetic open baffle designs.

[@dmptcb]

U are definitely correct I have box speakers and my magnepan 2.7 have stole the show nothing better in my opinion and I have them in a large room I just pull them out 3 feet from the back wall when I want to use them the only issue with magnepan is u need huge power to drive them better happy listening!

[@LevonArakelian]

Wow, so much valuable info! Love it. Thanks Ron and Clayton!

[@isaacsykes3]

First, I just want to say thank you for reading my question, I was stoked, then sadden, then stoked again. Clayton needs to be in home-theater, as well as the two channel space, although I think I may have a temporary solution that you can run by him...Three M3 Sapphires and an acoustically transparent screen, plus whatever subs he produces. Until then. push him on the open baffle center channel, or even open baffle bookshelves. That said I can not wait for the review, and thank you to you and your family for hosting this brilliant individual.

[@ABC-rh7zc]

A really good 2-channel system should have excellent center imaging. There's no real need for a center channel.

[@MichaelLivingston-me]

There's something about this business, call it audiophilia that's elusive, and very few times are there products that are overwhelmingly better than their peers at a specific price point. For example, when I look back at some of those things that made the market, I think it's because the audio market was just coming into its own. The AR 3's took the audio market and shook it up. Before that time, if you wanted deep bass, relatively speaking, you might have Bozaks or Klipsch corner horns. Early designers insisted that in order to build a decent sounding speaker you must start with nothing less than a 15 inch woofer. Forget about 8 or 10 inch. Henry Kloss went on to another bread and butter winner, the Advent speaker. Once again flying in the face of conventional wisdom. All that to build up to this point of admitting my own lack of experience (even though I've been involved since the 60's). I have yet to hear an open baffle cone or dome speaker which gave me a sensational sounding reproduction. I've been hugely impressed with large electrostatics from Martin Logan, or the Magnepan flat panel. Nonetheless, they needed augmented bass typically from a subwoofer in cabinet. Now the two of you come along and say, you can get fast deep bass, and tremendous clarity from an open baffle design? It sounds like heresy, but I just have to accept the fact I haven't heard the speakers you have. Maybe someday... Anyway, I find this video very interesting. Thanks for posting.

[@chrispicquet733]

Cool! Most Audiophiles snub their nose at Pro Audio! I used to be a soundman for a few bands,learned much about room reflections! The main reason that the Audiophile sound took off,was the introduction of AR 3a's,KLH's,and similar Sealed Box designs! The Early Large Horn Designs we're much closer to open baffle designs! I Hate to say this Ladies,but the Wife Factor has set back Audio for 40 yrs! Women don't like giant speakers in their homes,it degenerated with the popularity of the little Bose cubes,and now,guys are lucky to have a sound bar, and sub! I have Many Pro Drivers( JBL,EV,Atlas,etc...) That I use for new designs.I agree With your Concepts.

[@linkeddevices]

I don't know if 99 percent of us could actually place a speaker in its most optimum location. I think most of us would HAVE to place it along a wall with some clearance. it'd be really lavish to be able to have a dedicated room where the speakers are actually like somewhere in the middle of the room.

[@ABC-rh7zc]

Never heard his speakers or even heard of the brand so it was fun to learn about a new company and its products

[@snowpuppy77]

Snowpuppy approved! I enjoyed every minute of that. I am very proud to own one of Clayton's designs. By the way I have one of the early pairs of M3S and I have played them very loud a lot and sometimes louder than I can stand and have had no issues. If someone had issues then either their tweeters were defective, amp was clipping, or they will be deaf soon. That said nice to know the newer model has some more insurance for protection. The Sapphire series is furniture grade. They are beautiful. You will want to pull them out at least 3 ft from the front wall for great sound and because the back side of the speaker is also beautiful.

[@russmaleartist]

I have modified Dahlquist DQ10s, which are a combination of open baffles and closed boxes for the bass and the subwoofers. These speakers have the foundation of greatness . . . they just need to be updated with careful consideration and care.

[@anjinsan1977]

Carl Marchisotto (NOLA Speakers) did go on to improve on his old DQ10 type design.

[@ReflectedMiles]

Clayton is right that OB is old technology--60+ years--and it seems to cycle in popularity out on the fringe and in the DIY community, but never comes to much because it always loses when serious and practical engineering has to dominate (i.e., in pro). Otherwise, OB would have been the designs that most pros, semi-pros (bands/venues/home studios), and maybe even consumers wanted and were most manufactured, let alone being a "legitimate alternative," but they have significant time-alignment problems even short of self-cancellation issues at lower frequencies in the room, not just along the sides to create the dipole, and that is where the genius of the Dahlquist concept comes in--you're exactly right. OB needs users with an unchanging room of sufficient size and with acoustic expertise and pro measuring tools to set them as correctly as possible. Controlled directivity has never been enough to deal with that at lower frequencies. It was possible with Dahlquist to secure nearly all of the advantages of OB while boxing in the worst of the problems at a fraction of this price. Their "bass trap" was consistent and moved whenever and wherever the speakers did and without the free-air resonance behavior that wasn't mentioned, either.

[@AmazonasBiotop]

Super good interview! I like the technical discussion that gives some insight into how OB works. And my next type of speakers will be OB for sure. (I have no problems with 3 feets from the front wall, actually yesterday I moved my speakers 1½ feet closer to the front wall so I am now little bit further away than 3 feets currently.. .. dedicated listening room.)

[@chrisvinicombe9947]

Quality content guys probly the best open baffle explanation I've heard. I kept thinking headphones also solve all room issues 😉 Looking forward to the next video.

[@kenwebster5053]

Interesting, I am very familiar with side dispersion issues from my PA experience. This is particularly a problem with stage wedges that use horn mounted tweeters. We had a corner stage (yeah bad) but the issue was that the horns gave a narrow projection from the tweeters but the bass drivers were very wide. The performers were basically on axis so if their spectrum was balanced for them, the off axis spectrum was mostly just bass. The off axis bass bounced off the floor, ceiling and walls, around the corner and then out into the audience area where it polluted the house with excessive muddy out of phase bass. The venue (church) had zero acoustic treatment of course. The house speakers themselves had very clear, precise, balanced spectrum true sound reinforcement(exceptional for a church after installing half decent cables and applying EQ). This meant that anytime the stage monitors were run to sufficient level to be useful to the performers, they polluted the house sound badly. So my options were to either run the monitors too low to be useful, or EQ them to meld nicely with the house sound. The 2nd option meant they could be run at useful levels without polluting the house sound but for the performers, they sounded tinny and metalic. At the end of the day, the house is the customer for both the performers and the sound team. I wanted to deploy acoustic treatment around the stage &/or move it out of the corner but that got no traction. From this perspective I get the great significance of sound cancellation around the edges of open baffle speakers and the fact they produce dipole lobes. My question though is what do you do about the adverse effects of the inverted lobe reflecting off the front wall? That would be just as much energy as the in phase direct lobe that is the only one you want to hear. Surely this question is the real elephant in the room with open baffle speakers!

[@mfkhometheater7742]

What are Clayton's thoughts on Keele's CBT technology for constant directivity? I've been building open baffle since the mid 1990's and in 2009 I combined CBT with open baffle for the center speaker in my home theater. The combination of open baffle and CBT worked great and I will be using it again in my new theater. The new center will be a horizontal open baffle full CBT similar to the 2009 version and the left/right mains will be open baffle ground plain CBT's.

[@rotecrl9719]

Clayton's voice sounds awesome.

[@AviewFromUnder]

As a fella that has spent best part of 40 years putting large format sound systems in venues of all sizes. I share the same truth as this man. Direct to reflected ratios and system directivity is 90% of the pie chart of what matters! The largest flaw with the a speaker system large or small is directivity. Any loudspeaker you hear while in a lawn chair will have a good chance of being on a list of the best you will ever hear! Are you are sitting in your sheet rock den with your hifi, thinking you need some thousand dollar oxygen free RCA patch? Yes well its time for a new hobby because you don't get it and cant hear! All that said get some nice headphones perhaps 3 pairs problem solved!

[@Justwantahover]

I have built semi open driver speakers. Half way in the box and half way out of the box. With a bass tube treated speaker hole, these speakers have the warm box sound combined with the cold open cone sound (tweakable). More spacial sound and more control and extended highs on single driver speakers. I also do it with coaxials.

[@lucacorso_audiosystem]

The dipole question could be deeper. Is it okay to add 50% “reverb” sound in the room when the correct amount of reverb is already present in the recording? 🤔 Then how does such a system behave towards "fire", that is, the system's ability to correctly position the virtual sources in the environment? 🤔

[@LAKXx]

Truth be told, i'm one of those that just likes doing things different but i soon realized OB is not just a gimmick and actually sounds amazing. Still i couldn't help myself and strayed of the path once more so now when people enter my room i go like ; _Oh that? are just my one of a kind open baffle panels with decoupled drivers in a clamshell push pull configuration. Its no big deal lets move on_ But forreal, in the end it was not the need to be different but experimenting that has lead me to this setup and honestly, i tried alot of weird shenanigans but this config was to good not to keep using. They hang in the middle of my room and sound amazing from both sides, well if you forget the tweeters at least that is.

[@photobriangray]

The bass waveform discussion, my room creates a hole at what should be the main listening position from the main speakers and what would be a standard sub placement in line with the mains. To the extenat that leaning forward three feet, boom, lean back, nope. I remedied things by placing my sub in the MLP and finding the area in the back of the room that allowed for constant spl in the living room. Thought about bass traps, but moving the speaker forward, backward, left and right had minimal effect. There are some odd shapes in the room due to two hallways out and a stairwell. I am curious if the open baffle design would defeat the room.

[@andrewgillis8572]

open baffle speeds the placement process - great point - and makes your room the speaker cabinet, makes sense you could find a sweet spot inside an AR5 or a large Advent - mind you, you'd be tiny & be breathing fibreglass

[@bnaudio7813]

does anyone have any diy specs for the baffle size and how it relates to the speaker specs? aka if qts is this much it needs x width of baffle?

[@svtcontour]

I love my open baffles but while interaction with the room may be less in some ways, placement of open baffles are still more difficult IMO and also it needs quite a bit more distance behind it because you want the rear reflection to be delayed quite a bit. So I'd say open baffle are ideal for large rooms

[@cybernaab]

I know this isnt hifi, but i can recommend using decent quality free air car speakers such as a 6x9 size since they go below 50hz or 6.5 inch for midbass/fullrange 60hz and a subwoofer to build a simple super cheap open baffle system, ive been doing it now and i really enjoy the sound quality Since most car full range speakers are made to be used free air, they are perfect for open baffle. Ive even replaced the satelites on cheap logitech 2.1 systems with small 3/4/6 inch pioneer/jbl/kenwood fullrange freeair speakers in selfmade open baffle planks with very short wings. The sound quality difference is amazing, even for such cheap low class speakers it's a big change, so big even that i dont want to go back to normal ported or closed speaker boxes. As said in the video, the bass becomes less boomy, so if you like to watch movies with the open baffle car speakers i suggested i only recommend using the open baffle speakers for midbass midrange highs, and a boxed subwoofer for the lows to keep it cheap and simple

Great interview... would be super interested in his speakers if they were more affordable... I say this cause as recently as 2016/17 maybe 18, Clayton had the M4 at $1600-2000+ and I think there was an M3 Turbo version that I think may have been as low as $2000...Today the upgraded version starts at $4950. Hey your good and successful, you should get paid... I hope this virus goes away sooner than later.... but, in the meantime, maybe with discretional spending plunging, hopefully Clayton will bring the highly reviewed M4 back, and open his product to a much bigger audience... not only to people who can spend $3500 - $27,000... Regardless, obviously his success is deserving!!! Footnote... emailed Clayton to see in fact if M4's had been discontinued... He was nice enough to email back(Props)... and said they had been discontinued last year...Lowest entry level now $3450(M5's)... going in the wrong direction for sure!!! by 100%+ in a short time... discretionary spending is in a free fall at the moment, and there's no sight of the bottom... maybe that will encourage Clayton to bring back his highly regarded, and affordable M4's... Hope so... onto another Utah speaker maker for my next pair... Tekton Electron...$2250... pushing the limit, but will order this week... Cant wait!!!

Well I’m super familiar with the original M3 and these are on another level comparatively.

Question! Is there such a thing as the perfect room in terms of the proportions LxWxH and other features?

[@RedSinter]

All this makes total sense and love the concept. The issue is can and does anyone make a kit for this? I'd love to build a bookshelf sized Treble Mid Range and add a seald box sub. I don't have the room size at all for say a free standing 3 way Open Baffle. Or... is that even possible let alone practical. As l'm in a near field life and likely thats not going to change.

Very informative video! I'm considering pulling the trigger on a pair of Sapphire M5's next week, but I'm concerned about running them with my Cambridge CXA80 in a smallish room (11'x15'). Do you think this combo would overpower my room? I'll eventually upgrade to a lower wattage tube amp, but that won't be for another year or so.

[@Newrecordday2013]

I think you would be just fine honestly!

Clayton has come out with M4 and M6 that should also help with smaller rooms. I know this is a year old post but thought I'd put that out there.

[@ze_german2921]

Can this style of speakers play heavy metal and hip hop as well as it can Jazz? I'm assuming it would be best to add a sealed sub for different genre?

[@Vidar.m]

In my firs car i mounted some subwoofers behind the backseat no box ! Just a plywood sheet with holes for the woofers. Trunk itself was the box. It sounded good.

[@Vorss76]

Good video. Problem with audio 😁 how you manage not to hear during montage?

[@DethFromAbove1985]

I have fallen in love with the Dahlquist DQ-10s from the 70s. But below the waste they are closed baffle woofers and I use closed baffle subwoofers with them .

I lovedvthe SD Acoustics OBS3 in 19787. A ribbon tweeter and an open dipiloar midrange, with a ported bass box withe fhe the same 6" bass driver

Great looking speaker the M3 Sapphire :) hope the fabric comes off easily. The spatialaudio site really should get a better 3d modeler for the cgi, i use blender as a hobbyist modeling hifi gear and it really should realistic than that. excited for the upcoming review and this was a nice video and great topic.

Hi guys , 73 years old now, not a big music room, Casta B Horn Speakers, Audio Space 3i integrated tube amp, no boom or muddy sound, bass is there if in music, dynamics are all I have, very smooth balance neutral natural sound, learned all about resistance, capacitance, room has very little standing wave, diy cables , interconnects speaker cables, power cords, multiple purpose room, have huge space, 17’ room in dinning room where speaker faces, many say I have great sound, no perfect, but very involving music, no baffle speakers no room behind them, Casta‘S 2.5’ from wall, toed in 45 degrees, get floor to ceiling sound.

[@luke9822]

13:50 even though they were presented differently (one as a negative and the other a positive) it seems like you are saying that for both open baffle and box speakers, moving the speaker in the room is necessary to achieve the best sound. Is that not the case, or are open baffle forgiving and can be closer to a back wall? I'm not sure if there are similar aspects to something like a Magnepan quasi-ribbon style speaker, but it is my understanding that need *a lot* of room and are temperamental that way.

[@JerryRutten]

An open baffle needs more room behind the speaker, a box speaker needs more room to the sides of the speaker. So, when closer to the side wall, a box speaker needs more toe-in. When closer to the front wall the open baffle needs more toe-in.

[@luke9822]

@@JerryRutten thank you. Having my speaker wall in line with my entry door path presents a real challenge for good performances from speakers while not putting the speakers in the walk path. I'll be fairly close to the back wall. I would say no more than 1 ft or so.

[@brucermarino]

Thanks for an interesting presentation. As a fan and amateur designer of dipoles, I share your enthusiasm. Owners of box speakers, can greatly improve their in-room performance in relation to the issues you brought up by listening in the near field. I have only listened up to the discussion of the bass range, and wanted to mention that one still gets destructive and constructive interference from the back and side walls with dipoles, although it is diminished. The reflections from a dipole or a box with typical placement in the low end is also somewhat mitigated by the fact that the notional point source of a typical moving coil speaker is at multiple distances to the walls, ceiling, etc. This is even more significant with large planar drivers. Thanks!

[@StewartMarkley]

I am a big fan of nearfield listening but the main advantages are in the mid and high frequencies because they are directional and the ratio of direct to reflected sound that you hear is much reduced. The bass frequencies are omnidirectional and dont change much from proximity but rather are affected more by the standing waves peaks and null positions in the room.

[@cruise2023]

Again there are the Mark & Daniel mini monitors on the shelving behind! Have they been reviewed ye, if so when and if not when? thanks.

[@Newrecordday2013]

They are SVS ultras

[@geickmei]

I watched this whole video to see if you understood what causes the sound of open baffle speakers and didn't hear it. You didn't say a word about the direct and reflected sound in the room. It is the reflected that gives the depth and spaciousness and speaker disappearing that is so prized in audio circles. You need to address the positioning of the early reflected sound as you move speakers around. You can visualize this by making a drawing of the image model of the speakers in the room - draw the early reflections as additional virtual images on the other side of the walls, like mirror images of the speakers. Simultaneous benefit of reflected sound is power response. Image Model Theory enables you to draw a picture of the sound in the room.

[@joebandy6505]

When you do the review, please compare it to Magnepans. Thanks for all the great work!

[@porkchopspapi5757]

Once I heard an open baffle, most box speakers sounded like music coming out of a box.

[@Justwantahover]

I like single driver and coaxials and I build speakers with the driver mounted above the speaker hole (like one inch above). And the hole is bass vent treated (with a short wide tube). The driver is spaced from the hole by extension screws and thin plastic hose as the spacers. Easy and it beats any "normal" speaker hands down. They absolutely smoke my B&W 706s and they cost AU $2,400. And (as you said) there's no going back.

[@porkchopspapi5757]

@@Justwantahover you mean the driver is mounted out from the hole right?

Does open baffle require less watts to get them moving....?

[@rimcountryoutfitters]

So the room IS the box. 💡

[@WigandKleine]

Btw could you do a review on the X-Statik? That would be awesome

[@SuperMcgenius]

I had a Dayton Write pre amp and heard those speakers in a double stack with huge Mac tube amps🎉

[@iscmiscm]

I can never understand why some people go open baffle for the mid and treble and then marry it with a closed box bass unit. Great examples are most of the range from Martin Logan. They use this great electrostatic unit for the mid and treble and possibly the upper bass and then use a fairly small box for the bass. It is already hard enough to marry a very light panel with a relatively heavy cone without adding a box into the equation. I often wondered if the original esl from Quad would work well with an open baffle sub. My Dali Skyline 2000's are fully dipole and they also try somewhat to control vertical dispersion by using a very tall baffle, two mids and a very long ribbon tweeter. When driven and set up correctly, they sound awesome and I find it a shame that Dali stopped the range. I have two pairs of B&W DM70's and I am thinking of converting the second pair to open baffle bass, as the electrostatic unit is already a dipole down to 400 Hz.
