The best port placement in my opinion. Close to the end. My humble suggestion : 3 inches longer and the inside port tapered to the middle. I tried it using two dual cone speakers 4 ohms each wired in series. Good job sir!!! 👍💐👍🇵🇭
Thanks
I have found that plastic terminals are almost in all cases a source of air leaks. So I always mount terminal first and apply havy glue from inside. This prevents leaks. Additionally I use gaskets made from tiny foam between speakers and box to prevent leaks at front baffle.
All the drivers and the terminal cup came supplied with good gaskets.
You should chamfer at 45° the backside of the front panel where the speakers are mounted. Otherwise, the thick panel will block waves behind the speaker and effectively change its TS parameters.
The baffle is not that thick. Chamefering the back is not practical in this case.
Very high quality speaker and video.
Makes a lot of fun to watch and the speakers always look very nice!
Thanks mnan
The awesome thing about this design is that there is no ugly glued seam! :)
Thanks
You didn't make separate chambers for the woofer which you should or both driver interfere with each others air pressure
No, this is not the case. The drivers work in unison and in phase with the enclosure volume double that of one woofer. Each plays the same frequencies. If this were two fiffrent drivers, then yes, separate volumes are required since their responses are different and will then interfere with each other.
Love this speaker build. Quality of work is fantastic.
Glad you like it!
I Like the retro cabinet style! They are looking great.
Thanks so much!
Looks great, but it would look even better with hex screws. Everything looks better with hex screws.
Thanks. For this one I prefer the more subdued kook of the Philips head screws.

Sir iam from india i had denon AVR x2200 i wanna make center channel speaker what is best (2 ) 4ohms speaker series connection or (1) 8 ohms speaker best for avr life. and cross over must or not and how to make cross over pls tell me
🙋🏻♂️mr.soundblab I have a question here. First Thank you for the plans, content, and answering questions. I just built your 3 way floor standing speakers for my front left and right. Now looking into a center channel. I was wondering if you could give me some recommendations on a center to match those 3 way floor standers. Size is a concern and was thinking of just using the fountex and tweeters to make a small cabinet, any thoughts?
Big fan of your works
Great job. What speakers have you used? Are the woofers 4ohm and tweeter 8ohm? How did u do the double deep circle to level up the woofers to the wood?
Nice looking speaker and great vide, but...Horizontal MTM's with 2-way alignment have subpar lateral dispersion characteristics.
If the speaker is intended for listening +/-15 degrees, great. Otherwise, you will have combing in the frequency response beyond that listening bubble.
There other ways to mitigate these detrimental characteristics in Vance Dickason's Loudspeaker Design Cookbook.
I would argue that is bad either way because even on axis, what you hear is a combination of the on axis and off axis response
Much better way of clamping your veneer compared to the last video. Nice work table too.

Manufacturing quality excellent!
Thanks
What's that material?
The insulation material
Rahul Ravi It looks like scrap carpet padding.
How did you mount the crossover was it glued in or screwed in? Why didn't you install crossover before putting top on cabinet?
I think I glued it (was a long time ago...). I like to make sure that I can mount and remove the crossover even after the cabinet has been built.
No test video ? Why?

I have a random question. Someone stole my center channel from storage. Until I get the money I'd like to use two rears as my center. Is there a way I can wire them in series or parallel so that one would act as the left and one would act as the right?
Sorry if it's a stupid question, I'm pretty new to this stuff.
Thanks!
I'm starting to realize that this question was not a very good one. For some reason I was thinking that the center still somewhat separated the left and right sounds. But through more research it seems as if it is about 50/50 from left and right at all times and it just sends at a different frequency so that audio will be more prominent, correct?
I ended up just running my two small rears in series as my center and turning the volume up on them. Not perfect but, it seems to work okay for now.
Thanks!
Fantastic and sooo satisfying to watch...😍😍😍
Love from India...
Thanks
Super
Hi, what did you done to have that finish on the plywood panels? Only the spray at 6:23? What’s his name?
It is a clear polyurethane made by Rust-Oleum.
this is very nice work, have you done any off axis measurements?
Thanks. I normally do, yes.
I have not some thing to learn by seeing this video, I hope to learn how to make passive crossover or anything else in this video.
Didn’t want to sand off the router burn marks on the front edge?
Could this centre speaker be used on it's own effectively, without the right and left speakers?
It can't replace left and right speakers on its own, but can be used in a stereo pair as left and right speakers if you use them vertically. So, short answer is, no.
@@SoundBlab thank you for the reply. I have been exploring your channel and there is plenty of great alternatives for me to try.
me parece un excelente trabajo, estoy pensando hacer algo asi para mi tv
Did you do the measurements yourself in REW to make the crossover?
yes
@SoundBlab you're awesome, thank you so much for responding. Would it be possible for me to email you or something I'm just starting out in the hobby and just recently built my first 2way Bookshelf speakers thanks to some courses I took from AudioJudment on TH-cam. I just don't know how to go about measuring frequencies when it comes to odd speaker types (several woofers or other drivers), I want to learn to build all speaker types so I can build a home theater but I'm really clueless on the process for measuring all the frequencies for something like a center channel with several woofers of the same type and one tweeter. Im aware of the far field for the tweeter and far field + near field for the woofer on a Bookshelf 2way, but not for s center channel. Also I know we have to account for acoustical offset, this I learned to deduce using xsim with the frequency responses of the tweeter and woofer and by additional importing the frequency response of the drivers in parallel, then you change the acoustical offset of the woofer until the two graphs look about identical that's the offset.... but how do you go about this when it's a center channel ? I know that was a lot, I'm sorry, I'm really lost and I've been searching all over TH-cam but no tutorials 😢
@@SoundBlab please soundblab could you have a look at my question ?
What kind of nailer it is??
I don't have that nailer anymore, so not sure what brand it was, but it is an 18 gauge brad nailer.
If I were to do a build of this, but modify the box dimensions, so it's longer but more shallow but retains the same volume, would that work well? Basically I need a center with dimensions closer to a soundbar, doesn't have to be full on soundbar, but closer due to the dimensions of my room.
For the modelled crossover to work right, the size and shape of the baffle or front panel needs to remain the same. If you change it the frequency response will be off. Short answer is, no.
muy buen video me podrias decir que altavoces usastes para el projecto
Thanks. The woofers are from Silver Flute, and the Tweeter is Vifa.
hi there.., im also planning to build that to and i just want know what speaker and tweeter you use ... thanks.
Check out the details here: soundblab.net/product/home-theater-center-channel-speaker-build-plan/
@@SoundBlab ok ... thank you very much..
You make such nice looking speakers.
Thanks man!
Cara da hora!!... queria ter 1% do seu conhecimento. Show !!
Im your fan
Do you recommend the components you install or its just the box plans? On your website all you have are plans
I do not sell components, only the build plans that give you comprehensive parts list and where to buy with links. If its in a build plan, I would recommend the parts I use.
Can I purchase

Thanks
What about hardware from crossover, would they needed to be adjust ( I have watch other video's they claim, as needed) Thank you!
No adjustments needed. The crossover has been optimised for this driver and enclosure combination.
@@SoundBlab thanks
Good work! 👌
Thanks

are this stereo channel or just mono?
Its a mono center channel speaker
@@SoundBlab oh ok.
@@masprassaja3818 yes, and it actually could just as easy turned out to be a stereo Bluetooth active speaker if desired.
Bravo.
Rien à dire.👍🏻💪🏻
Just 1 question, at 2'30 what title 🎶 ?
