I’ve used singles of both A7.3 and A10.3 as centre channel (Lo passed as high as 100), and would definitely recommend the larger of the two if you can accommodate the enclosure size. Mine is a variation on one of the centre enclosures to which Dave posted a link to previously, with the front panel slanted up at 5dg.

I stopped 20 years ago sitting in the hot spot. Nowadays for me its mostly a/v. A friend who was part of Ozzy`s band found the same thing.Funny thing is I never thought I would get old.

Again, should all be identical across the front, but if must go smaller, then what can come closest in PRaT or at least in the critical 250-3500 Hz phone BW ['voice'] and in smaller HTs the CC may need a super tweeter to get enough off axis coverage on a three wide row, but I gather you won't have the baffle height for one if you need it, so academic.

In short, only a focussed over n' under is suitable for dual 'anything' for high speech intelligibility.

Okay, no progress yet on my center channel, but I got around to attaching all the wires on my new avr (Onkyo TX-RZ630) and ran the initial setup using the supplied calibration mic. My system is only 2.1 so far, as I'm using channels 6/7/8/9 for remote zones.
Anyway, was a bit surprised that after running the AccuEQ setup, it selected a crossover frequency of 40 Hz for my front speakers, and an LFP of LFE of 120 Hz. That seems like a lot of overlap doesn't it? My front speakers are MLTLs that with an F3 of about 43 Hz, so can reach down that far, but I expected that the two "crossovers" selected by AccuEQ would have less overlap. Is this expected? Is it reasonable/good?
Thanks,
Eric

Eric, sounds like you’re early on your journey down the rabbit hole of multi-channel. Some interesting features on that RZ series. In my own case, adding small PLIIz front height speakers (Pluvia7 in top corners) and research surrounds (A5.2) made a huge difference in the overall sensation of space and, well being surrounded by the on screen events - Kings Landing “battle” scene, for example.
Although it looks like Onkyo have departed from Audyssey and adopted their own calibration / EQ function, unless the interface and manual setup options buried a few layers deeper than the auto mode, you can still adjust those crossover frequencies on the fly to find settings that may work better for your ears than the defaults. I chose the setting of 80Hz labelled as THX standard for the front row, and 120Hz for the peripheral surrounds.

Have you tried the phono input? While I’ve not seriously listened to my ‘table in probably 5 years, I did test it out on the NR830, and it was surprisingly non-hurtful.

I continue to be amazed at the amount of functionality and relative ease of use the designers of modern surround receivers can cram into a single box. I think we all know guys who’ve spent more money on snake oil infused speaker and interconnects than your unit cost.

That's not the plan, but who knows.....presently planning to stop at 3.1!

Yes, the "manual" adjustments are still easily accessed, but I wanted to see what the auto mode came up with on its own. Actually, one of my main motivations for replacing my old stereo receiver with this unit was to be able to use the crossover to limit the low frequency inputs to my two front speakers. I was expecting the auto mode would cut them off higher. I may try 80 Hz for the fronts like you have set and see how I like that. The ironic thing is that I designed my front speakers to reach down close to 40 Hz, and now I've bought a sub and crossover and plan to prevent them from trying to. It makes me feel a little dirty somehow...

Haven't and probably won't. I haven't had a turntable since about 1985 and at Christmas gave all my albums to my daughter!

Pretty cool indeed for cheapskates like me!

These systems do time delay correction, so where there's a need it will 'gap' the XO same as is done with prosound horn/woofer[s] or similar speakers to get 'close enough' delay added when they aren't physically aligned.
