Answered in Post #9. I use three identical floor-standing full range speakers across the front for L/C/R and smaller floor standers for surround.

Re: HT Center Speaker Matching with Front Speakers

Agree with Kal the bass loading shouldn't be a consideration. Finding a center speaker with similar drivers and physical layout might be difficult if not impossible. There is a DIY option of finding a single TLS80 and hacking it up into a center. Otherwise, just buy a modern center or small bookshelf with a poly midbass and soft dome tweeter and let your Onkyo do its auto eq setup and see how close a match it can get timbrally. Not the end of world if not perfect match.

Re: HT Center Speaker Matching with Front Speakers

Early Spendors used the same HF with Bextrene woofer/mid. Might work.

I had a look at the AT-2 and it goes down to very low frequency output. May be I ought to ask a more "fundamental" question. Center speaker handles the speech section and that should be enough with less than 200Hz to may be 2.5KHz. So why do we need a full range speaker. Once I understand this may be I can move on.
The center is known mostly for voices but it does handle quite a bit more than that. Even if all it did was voices males can reach down to the 80Hz range so stopping at 200Hz would lead to a very thin sound.

As I have responded to theJman in my post 8. Do I need a full range speaker to match? Can you help me understand this philosophy?
Ideally you want to match your left and right to the center as the front 3 constitute the vast majority of the soundtrack from traditional 5/7.1 systems. For example, you don't want to have a center with a horn tweeter and left/right speakers with a soft dome tweeter as their voicing wouldn't be consistent. To the best of your ability you want to match the performance, capability and drivers across the front 3.

Given your situation it might be worth considering that phantom center option. In essence it takes the output that would have gone to a center channel and blends it into the left and right channel to create the illusion of a physical center speaker. Since it's unlikely you'll be able to match your current speakers it may a workable compromise.

If you take yourself too seriously, expect me to do the exact opposite
