Default Anyone using 28B for center speaker?

I know seems like overkill!

But makes lots of sense if you are trying to keep the same sonics and using a center speaker that needs power. B&W HTM1 D3 comes to mind.

In moves, I find there is so much that comes from the center channel. If not driven correctly, even with matched amps, I find the center channel may seem lower then the mains, even though mine are matched at the sound levels.

I find sometimes the Center can sound more recessed even though the levels are matched. You are correct though in that the Centers are typically smaller than the Left/Right speakers and usually need more power.

What I do to get things right is I listen to just the left and right speaker as a stereo setup - (no center on the surround) just a phantom center and then try and match the levels based on that by adding the center.

Thanks James!

I should have mentioned that I will be driving main speakers with 28B's.

In my current system, I've done all the tone tests etc. with my SP3 and using a sound pressure meter to check all the volumes for all speakers with my current Bryston amps. Maybe your suggestion gets a better result, I'll need to try that.

I am using a 9B Cubed for the center(Sonus Faber Cremona)and surrounds, while using 28B Cubed to drive the front left and right(TAD CR-1ís) and I am very happy with the results. I havenít ever given a thought to changing out the center channel amp.

Using all Cubed amps makes a lot of sense! My 6B is SST, is a few versions behind the Cube amps.

I am using the 7B3 to power my Wilson Mezzo centre speaker. While the Mezzo is pretty efficient at 96db, I found the 7B3 had better control over the 9BSST2. The 9B is now used for the 4 rears and has a channel free.

28B would be awesome, but absolutely not required in my situation.

Interesting, actually a good idea going with a 7B Cubed.

That is way too much for centre , Best is to balance all 3 on the front so you have harmony .

Uh, nope; I have my XCS2K driven by MC1.2KW x 3 / 3600 watts. The center is the hardest working channel in a home theater.

My L&R XRT2K’s are tri-amped with 4400 watts each.

That is what I was thinking. Right now I have my mains driven by Bryston 14B SST and centre by 6B SST. Although I have set the volumes equal for all three, the centre still doesn't keep up with the mains.

I'm looking to upgrade LCR and was thinking to have to upgrade the amps to be the same amp(s) for all three.
