Modify the crossovers. This will make the most substantial improvement, greater than cable tweaks. There is much room for improvement on your crossover boards.
taming studio 100's
Just got my studio 100's and am using it with audioquest type +6 cables, which are bi-wired. Connected to an Odyssey Stratos amp. The speaker is a bit brighter in my living room than anticipated. Have a large throw rug and bare floors otherwise. Any suggestions for new speaker cables so that I could tame the brightness? Speakers were dealer demos so they should otherwise be broken in. Also, would appreciate any input as far as subwoofer settings for my paradigm pw-2200. Subwoofer is next to left speaker. Living room is 16X25. Speakers are 7ft apart and listening space is about 14-15ft away. Any input would be appreciated.
