RSX 1056 biamp config with NHT 2.5i question

[youngjun91]

Hi, new 1056 owner here. Got a question for you all. My 86db speakers are not real easy to drive, although so far in my room, they sound very good with the 1056. I was thinking of buying a couple of subwoofer amps specifically made to drive the subwoofer section of my NHT 2.5's, namely the NHT SA-2 (120W). In essence, I would be biamping by having the front channel on the 1056 driving the the tweeter/mids and the woofer section would be driven by the sub amps. What do you all think? Do you think this would be a good setup? I'm thinking 75W will be plenty for the tweeter and midrange cone.

The one nice thing about the NHT SA-2 sub amps are that they have a gain control which I think will let me tailor the bass, i.e. have tone control. Altneratively, I was thinking of getting a Rotel (1050/1070?) amp for biamping. Or I might just get a regular 2 channel amp (used) with volume/gain pots like the Parasound or Marantz and use that for the bass section. What do you all think?

I took a look at the 2.5i's. Since the woofers are more of a built in sub setup I think you should be fine with the NHT amps.

Thanks! The NHT amp is a subwoofer amplifier, class G. Does anyone know what advantage that would have over say a regular power amp? I think the frequency is already crossed over in this amp if that is any advantage. Is this definitely better than a regular power amp?
