Center Channel Idea

[lawbadman]

What's up guys, I have an idea for a center channel that I want some suggestions on.

I plan on using 2 Dayton RS100 side by side in a tiny enclosure. They would play 20khz down to around 100hz
Now on both sides of the Dayton enclosure would be a Skar IX8 woofer in about a 0.3cf enclosure.

So, good idea or bad idea?
Suggestions?

Thanks all.

Better to use 1 than 2.

I need 2 of them for power handling. I was thinking of even 4.....
Why do you suggest 1?

You will experience comb filtering at high frequencies with two side by side. You either need a tweeter mounted above the two RS100's or must remove a RS100.

Power handling is a pretty meaningless spec.

As Face says, comb filtering means if you want to use more than 1, then you will need XOs to roll off all but 1 of the drivers below the ¼ wavelength of the centre-to-centre distance.

Even a horizontal TM only ( i.e. not a conventional D-Appolito) would probably give better results.

FWIW, I've been running single driver aka "full range" centers for over 5 years now, and have been happy with the results. Drivers are timbre matched to the floorstanding L&R mains, although the center enclosure is sized for convenience. As the center is crossed over to the summed mono LFE channel at 100Hz, the smaller enclosure isn't detrimental to bandwidth / SPL in my moderately small (340ft ^2) room, and at normal listening levels well below THX reference standard.

Why do you suggest 1?

Because you`d experience lobes in the horizontal plane, as close as +/-15 grad. The somewhat modern concept of a center channel is an expensive marketing creation full of flaws. Use one as Dave suggests, power handling is the least concern.
