Did you plan on bi-amping the speakers, or why two A23s?
FYI, the A23 cannot drive a 6 ohm speaker in bridged mode.

After reading the specs, I would say that two A-23s are not adequate. If you want to bi-amp, you should go with a A21+A23 combo. The OML-2 biamping is very scewed. The low range amp needs to drive both the woofer and midrange. The high range amp only needs to drive the tweeter. Thus, a much smaller amp is sufficient for the high range.
With that low sensitivity, you might want a pair of JC1s though...

When bi-amping you can use a powerful and less expensive amplifier for the lows, and a less powerful but more refined amplifier for the highs. For instance a solid state amplifier for the woofer and a tube amplifier for the tweeter.Originally posted by d"cure"
Ideally, though, the internal passive crossover in the speaker should be removed.

Peter is right, passive bi-amping (i.e., using the passive crossover inside the speaker) is a waste of money.
If you are dying to bi-amp for some reason, actively bi-amp. Otherwise, buy the A21.
If cost really isn't a concern, just buy two JC1's and be done with it.Karl

Peter thanks a lot,that is a huge information wooo! for the time i drive the lows with a musical fidelity a-300(indergrated amp) and the mid-high with a-23.I am very pleased with the sound but thinking if i ´m going for the a-21 and a good pre-amp will be better?Recently expirience was two weeks with classé cp-50 and ca-2200,great sound very inside music, colorfull sound(minus lots of money) but when i hear the halo a-23 i was attracted and hooked with the sound of this low price amp and start to make dreams of the highest range. Sorry the Jc-1s are out of my budget althouth in my country they selling with cool price.For the end worth to spent so much money for upgrading or must stay here where i am and spent for buying music?Comment

This is something I'm hung up on. Of course, I would love to have 7 JC-1 mono amps, one for each home theater channel, (talking 2 rear surround speakers, just to be clear) but just don't have the funds. In choosing whether to go with the A51 and A21 for a total of 7 channels, or the A52 and A23, it's... -
Hi,
I've been lurking for a while now and thought it was time to step out of the shadows.
I was wondering if the Halo A21 amp could realistically drive a 2 ohm load.
I have a pair of AR-9LS speakers (4 way 5 drivers) that I plan to tri-amp (via a DEQX... -
Hi all!
I'm a bit of a newbie in the Audiophile world so apologies for my crude description of my listening experience but here goes.
I have just purchased a Halo A23 to drive my dynaudio focus 220's. Out of the box my heart sank as I found the sound way too bright for my liking... -
hi there all, I have the C2/A52 pair driving a Quad L speaker system (21L/Center/12L).
I've been told (and read on these forums) that I should get the A23 for driving my 21L's as it would match the best.
Now, the A23 is much cheaper than the A21 and the 21L's do sound... -
Hello Everyone,
I am deciding on which amp to get for my center channel. I have Energy Veritas 2.3i powered by Parasound A21 and the rest by my denon 5800 receiver. I am slowly moving towards separate components. I am thinking about A23 or HCA 2200mkII or A51 which i think is too expensive...
