Fixing The Problem with Most Center Channel Speakers - The Rule Breaker

[@tomconnell7154]

I just finished building this after purchasing the plans. I have it paired with klipsch rp-280f towers for L & R channels. This replaced the rp-504c which I was always cranking up the volume and putting closed captions on as my favorite spot in the living room is 40 degrees off axis and I have to admit honestly the rule breaker build sounds so much more audibly clear off axis than the klipsch center channel. I can hear the dialog on movies much more pronounced and LEVEL across the seating from left to right up to around 50 degrees or so. I am not concerned one bit about tamber matching as I was more looking for a better experience with the channel that put out 90 % of movies and television. This thing is a winner!

[@Toid]

Thank you! I am so glad to hear that you are enjoying it! That is high praise. Sounds like it is doing exactly what it was intended. It's always good to hear people experiences and see what they paired it with. Thanks again for sharing!

[@Joey22688]

Ignoring all the expensive tools, you spent $100 + alot of time to beat a sub $50 center speaker?, why not compare it to something highend.

This bmr is on my bucket list of speaker projects to try and listen to. Great video! By the way, the German DIY loudspeaker magazin "Hobby Hifi" has designed an entire series of speakers based around that tectonic bmr with additional Dayton reference drivers. People seem to be quite impressed. The series is called "daydream" for anyone interested.

[@Toid]

Sweet! I’ll check them out. Thank you.

[@cabasse_music]

the performance of those BMRs is really amazing. i remember first reading/seeing polar plots of the d'appolito design in one of radio shack's speaker books as a kid and how it controls vertical dispersion (in normal upright mode) - so by flipping it on its side we are getting the worst of both worlds - great vertical dispersion and terrible horizontal.

[@Toid]

Yup. Except this design doesn’t have those deficiencies that a typical MTM has.

Awesome. Or, just use phantom center and never have a problem again wherever you sit.

[@sebastianjovancic9814]

Great for one person, but once you have people sitting outside of the sweet spot which is guaranteed in the standard home theater environment, the phantom center falls apart and you want a center channel to anchor the dialogue to the screen.

I solved the center speaker problem by no longer using a center. I just run 3 JBL 530s as L/C/R.

[@tshuper]

Great build. Really appreciate the additional focus on showing the measurements and theory in addition to the practical of the build. Also, with the crossover point so low, it makes me wonder if you could get away with dual 8" drivers to further extend the low end. The box would be pretty big, but if size doesn't matter, or if it's behind a projector screen then it could be a interesting build, even as a tabletop / room speaker. 🤔

[@jgsabato]

Nice project. It looks like it minimizes typical MTM issues. Size will limit output, but this will work for a lot of setups out there.

[@Toid]

I agree. We really wanted to go with something smaller as there aren’t many good options out there. When you go larger there’s quite a few different options that perform similarly. So the goal with this one was to design something that fits an area that seems overlooked.

[@themanwithIBS]

Nice. If you ever make a box out of pine and it doesn't look good, char it and put lacquer on it, it's gonna look good.

[@rakitakhan]

I notice that you don't use any gasket material. I know some drivers have it but this "tweeter" doesn't nor does the woofers. What's the point of sealing the rest of the box if you leave the drivers unsealed ? Just curious.

[@davidt8438]

I found the music a little dramatic for the video. It was more appropriate for a video of someone climbing Mt. Everest and making itt to the summit.

[@stevengagnon4777]

I like breaking the rules in speaker design...the rules will keep you inside the box... break some and you're outside the box...isn't that the goal in the first place... having a speaker the doesn't sound like a box.

[@feltsjc]

What are the downsides to this solution? There must be some reason manufacturers don't offer this option. All audio design choices are a compromise, so what is this design's weaker area? How would increasing the budget alleviate any weaknesses?

[@Elliott-Designs]

Sensitivity although good, isn't as good as it could be if the technology wasn't used through adding mass to control how the modes develop within the driver diaphragm. However I think probably the biggest reason you don't see manufacturers/companies using these is because it's proprietary tech to Tectonic Audio Labs. This means manufacturers of speakers might worry about stocking issues and raising the price of the drivers since there's no competition in the field. But for us as DIYers, we don't need to worry about the production of the drivers or where they come from. So for people like us I think they're amazing little drivers!

[@alexoncunha2138]

This looks like a perfect speaker to built in an amp, battery and wifi module and make it a "boom box".

[@Toid]

Thank you Dan. I really appreciate you and your insights. It helps me create better videos. I really thank you for that..

[@PhillioDoede]

Very cool little speaker. I see the appeal for a compact center channel with great off axis response for sure but personally I don't do anything with surround sound. I can see a similar version making a great self powered BT speaker though if the bass is good enough on its own. Also do you think that BMR driver would work in open baffle config instead of its own sealed chamber?

[@jimthvac100]

Why do they make most center channel speakers to only go as low as 100hz? I would think as low 80Hz would be better to accommodate the Male voice that can go as low as 85Hz. Especially if they are singing. I would almost think I may be missing out if the singing voice from a song was sent to the center channel and It may not be going low enough.

[@Toid]

It really depends on what your subwoofers are capable of in your personal taste. Most larger center channel speaker do you get crossed over at 80 or even 60 Hz. Small speakers like this, you start getting distortion creeping in when you try to cross over to low. You could crosses over at 80 hertz depending on your room. of course, with this being sealed you could really crossing over 80 hertz no matter what if you really wanted to.

[@zarboaudioprojects1430]

That's a great solution to the MTM center channel problem with video and measurements to back it up. I've messed with those woofers before... they're little beasts! I bet this setup plays pretty loudly before distortion creeps in.

Please do a 5.1 DIY and a how-to on setting up old working 5.0 speakers with a diy amp and sub

[@csimet]

Nice build. I would have liked to see the test measurements made at a distance of an average listener (say ~10-15 feet). I went even simpler... I ditched my traditional single center and re-used a pair of older 8 ohm bookshelf speakers I had laying around. I wired them in parallel to get the 4 ohms my AV needs and placed them on their sides (tweeters to the center) under the TV toed out from each other about 15-25 degrees. It actually works great and improved the center radiation pattern, spreading it out plenty to cover my main listening/seating positions. I can adjust them as needed, based on how wide I need it to cover. I can even phase offset them by setting one back a bit from the other to help remove middle low end dead spots. I'm surprised that manufacturer's don't make centers with adjustable patterns.

[@tomconnell7154]

Can you give more details - I have the klipsch rp-450c and I am sick of how poorly it performs off center and am searching for a wide sound stage patter for my center. Why I'm watching this video....

[@csimet]

@@tomconnell7154 Your speakers are rated to 50W RMS at 8 ohms, so you could hook them in parallel (4 ohm load net) and use a single 4 ohm 100W resistor in series to both to balance the draw from your amp so it does not sound louder than the other channels. If you don't add the resistor, you take the chance of overloading the amp's center channel (too much power draw).

I have THX Onkyo speakers, very similar to the one you're trying to fix by replacing the center. My mains are the same, just the center is sideways. I would be stoked if I could build all three mains just like this one. I have the skills, just don't have all the tools. If I were to replace the mains though, my goal would be to do all three fronts behind the screen. Subs could be below if I can't make them fit. I wouldn't have any idea what to buy, but for the fun of it, I'd rather build. My total experience building speakers was building my sub about 12 years ago. It's still running, though I did have to replace the amp once. I want to do more. I want to build two new subs.

[@abuzafi]

Center channels are typically dipole/mtm,, stand them up and it change its output to a wider dispersion for better off-axis listening, rather than on-axis/beaming.

[@goodgoat3096]

Wouldn't your cnc router have made quicker work at cutting out all of those layers? I would never leave any cnc tool running unattended, especially a laser. Moving the xover frequency down is the only way to attack the comb filtering issue and the speaker looks great. Nice project.

[@Toid]

Yeah, the one really nice thing about the Xtool is it has a flame sensor. If it ever senses that it might be burning, it will actually shut off the machine. You can also set the sensitivity level. But it is definitely good practice to stay with your machine. Especially when you’re starting to get used to them.

[@lokilowkey1]

Nice build! I think it would have been good to include a subjective listening portion to the review. Although the frequency response graph is night and day better, it would be good to hear your overall thoughts comparing the quality of the sound in the on vs off axis for both speakers.

Graph might be accurate and detailed but hearing it is another thing. So can I suggest for your next video if we can also hear it (in case you built something like that again)? Thanks and 💖

[@Elliott-Designs]

Hi mate, I get wanting to hear sound demos, but that's the problem. A sound recording will tell you practically nothing about how it sounds, since for 1. The way speakers behave differently in different rooms can change (for example good directivity properties like this translate equally well across different rooms, other speakers with worse directivity and off axis response can change how they sound quite drastically across different rooms). 2. You're hearing it through your own speakers/headphones and so if it were ideal speakers in an ideal room all you'd hear is your own speakers. Graphs, although a bit boring for some, actually can tell the whole picture if you look at the response both on and off axis. A good benefit about builds like this is it doesn't hurt much to just build one and try it out.

Just discovered your channel by recommendation from Erin - wow really awesome video! The end result came out looking sweet and probably performs more than enough for the typical household's living room setup. I'd be very interested in seeing distortion & compression figures - I assume the BMR will be a bottleneck in this regard.

[@Toid]

Thanks for coming by. I really appreciate it. And love everything Erin does. He’s such a great asset to the Audio community. The main issues with the BMR arise under 250hz, which is why we crossed it over higher than that. But you are correct. The BMR is low sensitivity and can only handle so much power. This type of design is good for small bedrooms and living rooms. Which is where I felt there really weren’t many good alternatives. When you go larger, there’s a lot of great designs that don’t have the off axis issues I’m describing in the video. Although, admittedly there are still a lot of bad designs as well.

I understand why you designed this for wide dispersion. It seems most manufactures put those woofers side by side to fit under the large flat screen. But I think I would rather build a custom stand under the TV to accommodate a Center channel similar to the Cinema 10's you build a while back but use an 8" like the Aurum Cantus AC-200MKII for wider dispersion; and use the Selenium D250-X GW 1" Phenolic Horn Driver with the Selenium HC23-25 1" Exponential Horn 100x40. then use the DS18 PRO-DKN25 Neodymium Driver with Aluminum Horn 1-3/8"-18 TPI for a tweeter using the Crossover frequencies of 1.2kHz and 3.5Khz. This would provide a very wide dispersion of anything coming out of that center channel. I would rather have the Best sounding center channel speaker than to compromise to fit in a narrow slot.
