Greetings,
I am embarking on a center LS project.
I have not found a great deal in the diy sector on the subject so I'm hoping to get some pointer in the right direction here.
This will (eventually )integrate into a 5/6.1 system.
Should it match acoustically with all speakers; my preference leans toword this.
Or is there focus on reproducing vocals?
Generally there are two woofers and one tweeter, are two woofers(in parallel)nessesary? I could guess this helps directionality.
I would like the cabinet to be very long, as to blend in with other aesthetics. Small speakers seem to me to be obtrusive and don't fit in anywhere.
Thoughts and suggestion?
Thanks

I'd try to keep the centre speaker as a point source. The horizontal MTM designs are a bad idea, unless you use a small full-range driver as the tweeter, and use a low crossover.
If it was mine, I'd use a small coaxial paired with a woofer or two.

What Chris said about the MTM.
As well the centre should have the same sonic charachter ad the L+R.

In a mtm would it be sensible to place the tweeter below the center line. ...as a way to compensate for centers being below the listener?
What do you want to do, change the position of the tweeter relative to the mids because you're putting it under the screen?
It would be sensible to avoid the MTM entirely.
The reason is that, for a conventional ~2kHz crossover point, the 2x mids will have very narrow directivity in the 1-2kHz range. ie, a range that's important for vocal clarity will be focused on a horizontally narrow area. You might hear speech fine, but anyone else in the room will struggle.
This is sub-optimal. By using a wide-range driver (the SB65 might be worth a look) or a coaxial, you can alleviate this issue by keeping the centre speaker a point source through the midrange and treble.

No need to convince me. Its just so common, I wanted other opinions.
The coax is a good idea; with two bass woofers?
But wouldn't it be difficult or impossible to get the tone (sonic character) to integrate well with other speakers?
I think for reasons discussed its a good idea to first try building a good center. I had owned many and they all, to me, miss the mark by a long way.
Because coaxials are few and rare, how about building my own? Hmm I'm starting to like the sound of a full range....again with side woofer or just a single full range.
How about somyhing radical like a full range and a coaxial....impossible to XO?
You could have a coaxial with as many or few woofers as you like, so long as the crossover is low enough to keep dispersion wide.
FWIW, 2nd-hand Kef speakers are a good source of coaxial drivers. I've been impressed with the HTS3001SE I've been using as desktop speakers (sealed & EQ'd).
The idea of the full-range or coaxial driver is to keep the mid-high range a point source. No point in using both in the same box.
With regards to matching to the rest of your speakers, do you have anything built so far?
The coaxial + woofer approach is a good one, and you could apply it to the left & right speakers. Use just the coaxial drivers for the rears/atmos speakers to keep them compact.

I like the idea of a single full range or coax as opposed to MTM sideways. You could do two each mid-bass with two each tweeters. You could experiment as to a down firing angle if they are way above head height when seated. You can also experiment with what sounds best; tweeters above the MR or MR above the tweeters...
I did some basic calculations and some drawings to get my head around the idea(s).
So I am thinking a small two way at the center from a 4in and 1in speaker. The pair would be complemented by a 6in woofer at either side with a crossover point at 440Hz. and for good measure the woofers could also be angled at roughly 30 degrees.
This should provide pretty good point source for all listeners from 5-8meters.
My circle drill has arrived so now i can build a prototype....
