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.Political Correctness'.........defined

That's what makes all these mods so much fun . . . and addicting.

i find it odd to listen to music through an HT system....too much center channel i think...Marantz 1152 DC- Denon DP 1200, Soundsmith Carmen MKII- ADS L980 - Blue Jeans IC's -
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!Up

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.

One last shot of this project showing Trey's custom plate installed with MIT Shotgun cables and jumpers attached.
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:Political Correctness'.........defined

NOW! I see what you were talking about, very nice job. Looks like some thing I might have come up with if I had those speakers.

Have you narrowed down the low end caps Jesse? Is it still looking like Calrity Cap ESA's? They would be a fine choice.
Taken from a recent Audioholics reply regarding "Club Polk" and Polk speakers:
"I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion."![:\](https://forum.polkaudio.com/resources/emoji/confused.png ":\")
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?I disabled signatures. -

Great choice! Years before the invention of the CD, we used Gaucho (vinyl!) to audition & tweek his new system w/powered sub.Things are getting better... ...Tonight I put in the same CD, Gaucho... ...it's a major improvement.....I listened to the entire CD.
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.

LOL! Can't wait to see serious if this isn't! Is your CC next?...it'll be a bit more serious than this one.
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.
