Actually, I think we agree - I was trying to say the same thing. The center should be placed horizontally, the bookshelf speakers vertically. If I was unclear on that, apologies

It seems I have said it wrong. We should put center channel vertically. Only then will waveguides in both speakers do the same thing.

EDIT: funny though. It seems that both C25 and C205 have a waveguide flipped 90 degrees, compared to all other revel speakers (and other revels center channels).

It will be out by an inch of the shelf!

That would work. Still best if you can fill the space with acoustic foam (or the like) behind the speaker.

The vast majority of people don't do this with their cabinet placed center speakers and are still happy with the results. However, if we are talking about "best practices," absorbing the interior of the mounting space is recommended

Hey John.
Here's a theoretical for you.

I'm pretty much set on replacing my Emotiva monoblocks with an ATI Signature amp this spring.
Looking at 2 options:
The 6002 2-channel 300wpc or a 4004 4-channel 200wpc and bi-amping.

I have Studio2s
Any thoughts, preferences?
Thanks

I have listened to a single Studio2 bi-amped with a 6002 and found an improvement. Given the choices above, I would bi-amp with a 4004 or find a good deal on a 6004 or 6005.

Boy, I don't consider myself an expert on amps - others in this thread can probably comment more specifically on those models than I can. I am running my F208s currently with an Emotiva XPA3, at least some of the time, and it seems to be doing just fine. Not bi-amping.

I do know the Ultimas offer more difficult loads than the Performas, though. RichB and @gsr can probably answer more authoritatively. When I visited Mark Levinson back middle of November they were powering Salon2s off their integrated and their 532s, and it sounded very clean. Realize that ML is in a whole different league, price-wise. The Salon2s were not bi-amped either.

I can offer this statement from Kevin Voecks, re: bi-amping:

I too, have heard (positive) effects from passive bi-amping. If the speaker is competently designed, you would never want to insert active crossovers, except for a rare case in which the transfer function required to properly “cross-over” the speaker is published and properly implemented. Otherwise, passive bi-amping can offer sonic improvements. One reason is likely that the impedance outside the pass-band rises dramatically—thus resulting in the amp not being significantly utilized outside the intended frequency range. So for example, an amp dedicated to the high-frequency section of a speaker (whether that is a tweeter alone, or perhaps a tweeter and midrange), will not have significant current draw at low frequencies, resulting in lower distortion.
RichB, gsr and bigguyca like this.

AFAIK, not even on the drawing board. Performa3 was new in 2014. Looking at past history, Revel does not often refresh a lineup in less than 7 or 8 years. Concerta2 was refreshed last year from the original series released in 2006. I would guess the next iteration of Performa is at least 3 to 4 years away.

When you have a speaker that to-this-day is still beating competition in double blind testing, there is not much reason to change something just for the sake of updating it

I wonder if they will powered the bass section with REQ included. The would address 90% of the Schroeder frequency issues.

I would suggest seeking out Revel speaker articles & reviews going back 20 years in order to learn about Revel's philosophy on speaker design and releases.
These aren't Honda Civics.
In Revel Years, the Performa 3s are but pups.
The Ultima2 line dates to 2008. I bought mine in early 2013 and almost 4 years later they sound as good as ever.
The advantage, as people who buy Revel well know, is your enjoyment will last for years perhaps even for good.

When there is measurable improvement, you'll see a new release.
Until then, you can keep searching.
