Will this amp trick work for increasing bass performance?
I'm considering matching Focal Utopia Scala Evo with two amps for bi-amping, to separate bass and mid/high.
I'm considering the Pass Labs XP-32 pre-amp, which has individual volume controls for each channel/amp. By slightly increasing bass amp volume over mid/high amp volume, I get to feel more punch from the 11" woofers. The crossover in the Focals cuts off at 220Hz, so only bass and sub bass are affected.
Which two power amps would you consider? Power amp budget is about $30K. Was told Focals like power, so >250W for bass amp seems the minimum. Pre amp will likely be Pass Labs XP-32.
Maybe Pass Labs X250.8 + X150.8 or X250.8 + XA60.8?
Your thoughts please? Any other ideas to get more bass performance from the 11" woofers in the Focals? Subwoofer is not an option. I know McIntosh has a pre-amp with equalizer, which would solve the problem too. But I always thought EQs are a no-no.

I have to agree with millercarbon on this one, that is that a DBA would be the way to go. That's a really large room for two 11" woofers! I see that the rear of the speakers has speakers terminals labeled "Bass Input". Does that mean you can bypass the internal cross-over? IF so, then you can, go here: https://www.marchandelec.com/xm44-electronic-crossover.html and purchase an external crossover (2 way any slopes you like and control the gain as well) requires a second amp of course. The cross-over will run you about $1500-$1700, depending on options, like fully balanced, tubes etc. Then borrow an amp and give it a try, seems to be a cheap experiment given the $$$$ you are willing to spend. |
