    Things are getting better.

    I tried listening to a CD once before on my HT rig in stereo, didn't make it past the first song...just horrible. Tonight I put in the same CD, Gaucho and while not in the same league as the big rig, it's a major improvement.....I listened to the entire CD.

    That's what makes all these mods so much fun . . . and addicting. And of course it's only going to get better as the new Xover components burn in.

    i find it odd to listen to music through an HT system....too much center channel i think...

    That's what the 'stereo' listening mode is for. ;)

    To me music only sounds good in either Stereo, multichannel stereo (if we're partying) or if it is a 5.1 music track. Blu-Ray Concerts are usually pretty good in 5.1, placing emphasis on the left and right channels while using the center only for a little bit of center stage fill.

    That F1nut listened to a whole CD seems a HUGE improvement!

    Have you narrowed down the low end caps Jesse? Is it still looking like Calrity Cap ESA's? They would be a fine choice.

    "I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion." :\
    My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

    Sheeeeeze... That's some cool stuff.
    So, have you been spending much time listening to music on these since all this? What are your impressions now?

    How did you determine what changes were necessary, which parts to use, and how to build/design?

    Great choice! Years before the invention of the CD, we used Gaucho (vinyl!) to audition & tweek his new system w/powered sub.
    Side note: did you retain any of the stock Polk wire? I found theirs between the BPs & XO PCB (& the mids, & "subs") pretty lame. Oops! Sorry. I hope this doesn't ignite mudslinging, er, debate.

    LOL! Can't wait to see serious if this isn't! Is your CC next?

    Another side note: do your 'A7 mid & subs share the same space? That is, no divider between them?

    Thanks for indulging me.

    Ok(!) on thread title correction!!

    Since you've dissected both XOs*, your take on the accuracy of the web site's listed frequencies?
    'A6 - 2.2K
    'A7 - 2.7K

    Thx, tony
