THD and SNR are definitely things to think about when going down to 2 ohms. Maybe I didn't read the whole post, but I don't know why you would want 2 component sets running. It's really not going to be much louder at all, because each set is getting 1/2 the power it would normally be getting.

 

Yeah, you should reread the whole post. We're talking about bridging components that have dual inputs. So instead of the set only getting, say 75W, the woofer and tweeter are getting ~150W each at 2ohm. I think that is how it was described.

 

Focals kick ***! So much cleaner and flatter than MB Quarts. I think I have seen components bridged like that, but you would most probably get much cleaner sound by going to a truly bi-ampable speaker. Also, Focals kick ***! If you can't afford those, my Alpine Type-X components are some of the best made, and can be bi-amped. They're really flat-sounding though, so if you're going for a "bright" sound, stick to MBQ.

 

Once again... speakers CAN'T be bridged. They can be connected in series, parallel or a combination of the two. Amplifiers are what get bridged.
