[@noelcarlson7592]

I really appreciate you posting this. You have given me confidence that I can build great speakers myself. As a finish carpenter, I will say that cutting square edges on the ports with a mitre saw is a very risky move and one that viewers should be aware of, Not only for your liability but for their safety. A round surface gives no stability against the fence to hold the port securely while being cut and can easily be caught and ripped through the saw taking fingers with it. I wish I had your CNC machine.

[@tysonjensen2175]

as a fellow woodworker, I was thinking the exact same thing. Great video though, thanks for posting!

[@gilph3]

I’d thought the bad part was when he was cutting the posts off the ports, but when I saw him cut the squares with fingers in the ports...YIKES

[@cici235]

Several years ago I met Bruce Edgar in his home. He was a contributing editor for speaker Builder magazine. I later sent him a pair of Dynaudio drivers and asked him to try them in a mid-range Traxic Horn speaker design he was working on. He was so impressed with the speakers that when he returned the them, he also included the hand-built horns that he had designed. I later built a Pro sound system using the hand built horns with with Peavy Black Widow speakers and a set of tweeter horns. I've lost my high frequency hearing because of those speakers. Oh, but how much fun they were to listen too. This traxic midrange horn that was very similar to a design that ended up in a Klipsch speaker that Bruce designed for them.

[@ElCidPhysics90]

Love seeing the grooves and rabbets being used

[@sygad1]

Nice build and amazing colour but I was curious why you used crimp connectors and not solder and why there was no speaker gasket / threaded inserts for speaker screws.

[@epi2045]

Awesome DIY. Klipsch has been raising prices (even before the pandemic) based on heavy marketing. I do like their sensitive speakers and this DIY project is really interesting.

[@patrickrosington1174]

Klipsch arent even that sensitive about the same as most other speakers in the range. The way they do their testing is wrong and the opposite of what is basically agreed upon so that they can get these higher numbers to deceive people. ill never buy Klipsch just because of that

[@epi2045]

@@patrickrosington1174 That’s interesting. Ages ago I owned a pair of Klipsch KG 5.2’s. Spec wise it was 96 db 34-20KHZ. They were the shortest ownership I’ve had for any speaker. Sold them after a 8 mos. I don’t believe for a moment it went down to 34Hz. Too harsh and bass was flat.

[@duroxkilo]

I read someone on here (KZbin) bought some used ones from a theater that was closing down. He said they were the best speakers he ever used. I believe he used them for a 2channel setup

As an owner of a full klipsch system these make me jelly!!!! I'm going to have to build a set now.

[@number1pappy]

I've always wanted to do this. I actually have a small wood shop and I've worked with wood for years now. I'm also an avid fan of music and home theater. I've always wanted to make an exact copy of high quality high end speaker to see how much cheaper I could build one instead of just buying it. I of course would need to be able to find and buy the actual drivers and either crossovers intact of atleast have the schematic for the crossovers so I could build them as well. As far as the cabinet I could of course just build them to the same measurements as the original. One of these days I'll do it....

[@rogerpurcell9444]

Great build. But I will never put cross overs in my cabinets again. If you leave them external you can modify it anytime and hide them any where. May need more wire to hide stuff but a lot easier to tweak.

[@csj9619]

[@patrickkilian515]

Like the hand blocking the screw penetrating the speaker when screwing it in with the drill. Thats literally the most important part of this build ha!

[@Toid]

Thank you! I appreciate it. I've always wanted to recreate the definitive technologies or even the golden ear. I used to have some, I ended up giving them away to a friend that always wanted them when I started really getting into speaker building. That is definitely on the list to build someday.

@@Toid I remember when the SDA-SRS speakers came out. They were a beast and sounded pretty good. They were not as transparent as the Apogee Scintilla or as fast but they made a good showing of themselves. Nothing like playing Ride of the valkyries with a PS Audio 200Cx cranked through them. Would make a fun play. Then again the Klipsch Korner horns were awesome too! Oh the old speakers, so many good ones to be had. For our system at home we have a set of four KD-4 for the corners and a KD-2.5 MTM for the center. Great image in a bad listening space. Nice build. Did you consider trying to source the actual drivers used in the KTP speakers?

[@josephhertzberg2734]

These remind me of my Econowave-pro speakers I built about 10 years ago. I still have them, tuned the box to 50hz, same waveguide as here, with an Eminence Kappa Pro 12". They are so good!!

[@josephhertzberg2734]

@@keithmarlowe5569 winisd is pretty easy to use. Just mess around with it. Most drivers are in the database and if not you can usually find the TS parameters for your specific drivers, which will lead you to porting requirements across variable box sizes.

First, I really enjoy the videos, and the fact that you make affordable alternatives to really high priced speakers. So thank you for the great content! I have a question. My room is 14x17x8 with the TV on the 14ft wall. Which do you think would give us the best HT experience for LCRs? The cinema 6, or these cinema 10s? We are a 99% movie/TV family. Very little music. I'll definitely be using the 10s for my surrounds, and our seating arrangement covers 30° left and right from the center of the tv. I have room for either design. Thank you!

[@tmdillon1969]

I'm moving away from home theater but I'm a big fan of the Klipsch Heritage series. My "money is no problem" purchase would be some custom Cornwalls but that ain't gonna happen. These look like they could combine Heresy and Cornwall attributes. If you were building these for 2 channel music listening what changes would you make to the components and/or cabinet? Given my skills at this point, I definitely do not want to go 100% DIY and your plans look like a great resource for the cautious DIYer. I've built two sets of CSS speakers and I'm rehabbing some Cerwin Vegas currently.

[@Anders357]

Projects such as these, remind me of a project that is still popular where i live. Its called Tangen AVdesign inConcert Miles. Using two Beyma 15p80Nd 15" pro drivers and a Beyma TPL-150H tweeter horn. Its not cheap, but quality seems to be really high. 2022 these will cost you around 2200-2700 euro to build. They can be used with passive filtering, but active seems to be the way, to keep that +100 db efficiency and dynamics. One builder went from Klipsch RF-7 Mk II to inConcert Miles, and he said they were way better in every aspect, plus they can play much louder. And RF-7 Mk II cost around 6000 euro here. There is a few threads on the inConcerts, also in english.

[@housinit]

Awesome! Would love to see some EAW inspired cinema speakers. Fell in love with EAW loudspeakers when I worked in pro audio in San Francisco. We had a 2 million dollar rental warehouse with mostly EAW and some Community gear. I'm definitely a Klipsch fan, but absolutely love EAW's sound.

I am wanting to build a sealed speaker using a horn. but my Woofer (a 12" SB34NRX75-6 needs crossed below 500Hz so thinking of a four way using the Eminence Beta-8A to bridge between the Woofer and the Horn. probably 200Hz, 850Hz and 4kHz. where the Horn I want to use can cross Selenium HC23-25 and the Selenium D250-X. Not sure what tweeter to use but probably the Beston RT002A Ribbon Tweeter. Think I only seen you build two ways with a Horn and woofer. But what is your opinion on this design?

Hi, thanks a lot for your perfect content! Please continue 😁 I have a question. I used to have Klipsch RF62 in my dedicated room. I changed them recently. Now I'm listening to them in stereo in my living room and while a like their sound I find their look too "common". Do you think there is a chance I can build new cabinets and reuse the same electronic components without losing the sound I like? Or even improve it? Thanks in advance for your advise. Stéphane

[@mrinalbarotra791]

Loved it. How well do they image? How was the Bass? Tight and punchy? Horn Tweeters or compression drivers, I keep hearing that they are shrill and tiring for long listening. What was your experience with these? Can these be considered for stereo system? Thank you for your content.

[@Toid]

One of the great things about this waveguide, is it doesn't have the honkiness associated with typical compression drivers in a horn. I have no issues listening to these without tiring out. It should be pointed out that these are really designed to be crossed over to a subwoofer around 80hz. So you aren't going to get a lot of bass below that.

[@drconflict629]

Really great content man.

[@NigelYoung-tg8op]

Great job. Which CNC machine and software would you recommend - yours seems to work well. :)

[@JR-ho5qm]

Great videos! have you experimented much with higher quality crossover parts, do you feel that spending more money on inductors, resistors, capacitors and speaker wire can improve the clarity of the speakers? Thanks! 🔈👍🏻

[@Renrondog]

JR, I can answer that. If your building high end stereo speakers, AND you have the high quality front end components then yes. It's a balancing act, $60 foil caps on a $120 woofer is a waste. Same cap on a $250 mid or tweeter might be mid price. Balance the XO parts with the drivers. IMO XO should be about 1/2 to 2/3 the cost of the drivers. Of course it depends on the order of the XO and # of parts.

[@aug.jam.1]

Believe me it's not a waste. With quality components on cheap drivers you can make them sound very very good indeed and really make them sound very premium. Also if the person who.made this video could add gaskets, screw inserts as well as resonating deadening stuffing in the cabinet that would help a lot as well for (sound) quality. Still a nice job and good looking speakers

[@bryandickerson5365]

Somewhere around 3:40 the background music was almost in tune with the CNC machine…almost ;^)

Hi Toid, i have built a few speakers over the yesrs and notice you used no panel damping or stuffing, are you not concerned about cabinet resonance, standing waves and rear reflections back to the woofer cone? Another great video by the way.

[@Toid]

That's a great question. It wasn't necessary on this build, but it never hurts to add it.

[@jaydorsett1580]

Just wondering why not rabbet your panels together and run more dados? Or run mitered corner blocks for better support of the boxes? Is it just not necessary or just to simplify? As a more traditional cabinet maker im just learning why. Thanks for the vids!

[@Toid]

It’s not necessary. The most important thing in cabinet making with speaker building is creating a dead cabinet. And by that we mean a non-resonant cabinet. And that’s what the internal bracing is designed to do, along with the type of material and the thickness. It all place are roll.

I had a set of "homebuilt" speakers similar in size and shape to the JBL C-34 (1950s-60s) design. They were different from the JBL though, because the back at the corner was "open" to the wall corner at the bottom. The instructions were to sit the speaker 2" from each of the walls at the corner. It seems that they were copies of a Klipsch design. 12" woofer, 6 or 8" midrange, and a horn tweeter. Anyone know of a similar design? Lost'em in a house fire, but I loved'em. After I posted this I went hunting and found the original design. They were by Electro-Voice Aristocrat corner speaker copies, and Paul Klipsch designed them for E-V.

This is the Cnc4newbie pro4848bl. I'm a huge fan of going with a 4-ft by 4 ft if you can. You end up wasting a lot less material if you're going to use sheet goods. But if you don't need to sheet goods, you can obviously go with a much smaller size. And for those that don't want to go with the pro model, they have the newcarve, which is a little less expensive.

It’s really disturbing that speakers that cost that much can be replicated for around $500. Not to mention you know the company pays much less than $500. For the materials to make their speakers.
