Default I wonder if anyone can help??


I am considering building one of these:

Click the image to open in full size.


Now I know what your thinking.....who is this loon......but hear me out!

I have been lucky enough to acquire a bare enclosure for this centre channel speaker. it is a beast and weighs a fair amount....its heavily braced with a matrix type affair and substantially clad with bituminous deaning material. oh and the finish is exquisite.

So I guess my question is what drivers would best match the one's in the production model??? it has a very wide frequency response and very accurate and purely natural tonal balance. the frequency response is 32hz-100khz, i have no need for such a high upper so could trade a little for more extension but the tonal balance and pure dynamics is more important.

Also the site describes an ultra low distortion network.....does anyone have any ideas as to what design is/or could be used?

Thanks for any help on my newest project it is much appreciated.

Ask monitor?

HiVi woofers/mid might be a good choice, with whatever ribbon you can get to fit, but it'll take a lot of work to get this speaker 'right', and may not be worth the effort.

what drivers do YOUR main left and right speakers use.
It will be more important to match the centre channel to whatever L/R it is going to work with than to try to match what some "advertising" literature says

Make yourself a list of drivers that might fit the cabinet would be the first thing to do.

the mid-woofer spacing would tend to indicate a low x-o point of around 750 or below, but if you can find a beefy enough driver for the small central mid, I'd try to push even lower, say 350?

Andy G is right !!!!!!!!!!!!!!!!!

My best home theater setups were.........

3 cerwin vega dx9's across the front (couldn't find 1 more pair).
3 cerwin vega v12f across the front
5 radio shack pro cs55s (lineam tweet center used as d'appollito)
(2 as surround)

and 7 yamaha 3-ways with the 8" (used to sell for $100/pair)
(used 4 in rear for a dual speaker making a dipole).

dx-9 were loud and great cranked, v12f were very good and very deep, but rat shack lineaums were cleanest upper detail (too bad I needed volume at 11 or these would have worked fine).

I had to raise the tv so the bottom of the screen was flush with the top of the speaker cabinter.

If you do not have the exact speaker across the front, the center channel stands out compared to the front wall of sound.

When I ran the same large speakers front and back, the surround sound didn't sound bad at all.
