Thoughts from the customer?
"First off, I'd like to thank Trey for job well done. He quoted me 2 1/2 weeks time door to door and it was only 2 weeks and that's 2,500 miles away! What an improvement these crossovers make for music. More detailed tighter bass and cleaner sound. Almost all day Saturday I listened to my music from pop rock, jazz and classical. Putting my system in 5 channel stereo was incredible. Then switching it to Pure Audio so I get full range and just the front RtiA7's is a BIG improvement. The tighter bass and detailed sound coming from just running the front's is a big improvement! I haven't had time to pop in some moves. I've run the YPAO but I want to dial it in with my SPL meter before I pop in my Master and Commander, Avatar and what not to test it out! Again I can not thank Trey enough for the quality and good service I got on these crossovers! Now the rabbit hole gets deeper... gotta upgrade my sub, get a NAS for my lossless files...maybe an amp!!! " - George (Polk Audio RTiA7/CSiA6 Fortress Level Mods)

"I have received the crossovers and installed them right away. The quality of the work you did Trey is outstanding, it's too bad those x-overs are inside the speaker and not outside. Also I have never received the package that would be that well packed.
I am in the process of burning the crossovers in, but I can already hear a difference in sound. I don't know how to describe it but my it is much more detailed, specially in a mid area. They also sound cleaner. Thanks so much for the awesome communication you were able to provide during the process. I just realised we have exchanged about 70 emails all together. That's more then I posted comments on this forum :-)." - Chris (Polk Audio RTiA7/CSiA6 Fortress Level Mods)
