    Wow. Beautiful work. Now step it up and do a pair of RTIA9's and a CSIA6. I'll send you my address when complete. Very nice craftsmanship Jesse.

    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!

    Update: My search for suitable gasket material for the new binding post plates lead me to CRG Products (www.crgproducts.com) and a wonderful lady named Laurie Way.....outstanding customer service! What I ended up with is product code 1746A, which is a thin compressible closed cell foam with a PSA backing. Some careful measuring, a bunch of single edge razor blades and a custom made hole punch resulted in the following.

    At this point I am confident that the crossovers are fully burned in and once again the results are outstanding. All the usual improvements apply. :cool:

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

    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.

    Side note: did you retain any of the stock Polk wire?

    Yes, all the wire from the crossover to the drivers is stock. It's not the best, but it's not the worst. Compared to the crossover upgrades it would be a minimal improvement at best.
    Is your CC next?

    The center channel was done at the same time in the same fashion. One of the pics shows it. I did the surrounds at a later date.
    do your 'A7 mid & subs share the same space? That is, no divider between them?

    Yes, they all do.

    Just realized after all this time that I made a mistake in the thread title. It should have been RTiA7 and CSiA6.
