Perfect match for ATC speakers


Hi,
I'm upgrading my audio setup and have decided to go for ATC SCM 11, and now have to choose the amp.
Any recommendation for these speakers?

Thanks,

Well, not to be discouraging, but to be informative:

you've done the opposite of what I advise: try first to find efficient speakers you love, using sensitivity of 90 db as a starting goal.

you bought very inefficient speakers, low sensitivity.

Sensitivity: 85dB @ 1W @ 1metre

LOW sensitivity Speakers need HIGH Powered Amps. That increases the cost, size, weight, heat of required amps. All that reduces placement options. All that makes it harder to try Tubes in the future.

What size space, and what volumes will you be wanting?

If you can, I suggest you return them.


If not: also consider this:

Their specs appear to be honest regarding their limited ability to produce bass:

Frequency Response (-6dB): 56Hz-22kHz

Due to both limiting factors: start with the idea of eventually using a single or pair of self-powered sub(s). And, make sure your preamp or integrated amp has PRE-OUT.

You want to send the bass signals out to another amp, so your primary amp only needs to amplify upper bass, mids, and highs. It can then be lower power, and the speakers will sound better not trying to make low bass. 

Raven says low bass is 65% of the power needs.

" High-Pass Crossover

This addition to the Avian series provides an extraordinary advantage when using a subwoofer. It frees the power amp from 65% of the load it normally has to bear. This is like tripling the power of the amplifier in terms of its ability to drive speakers. It also frees smaller speakers from reproducing low bass frequencies that they really don’t reproduce very well which lowers overall distortion. This is all achieved with a gentle 6db per octave slope making it easy to achieve a seamless transition with a good quality subwoofer."

"That above statement is BS."

I think you meant to say that advice is BS.

KEF's are loved by many, that doesn't change my advice: TRY to find a more efficient speaker you love as much!
