Hello,
I currently have an Audax diy 7.1 system that I built in 2002/03. I have moved to a new home and the new basement HT will be much larger than the old HT. The dimensions will be approx 30x17. I am considering replacing the two rear channel speakers with something like the QS8. I'll keep the Audax surronds and L/C/R speakers. The Audax surrounds and rears have 5-1/4" woofs and 1" tweets. I'm using an HK AVR7200 for power. Does anyone see a drawback to this setup? I read somewhere that this type of speaker doesn't have to be a perfect match with the main speakers.
