Thoughts from the customer?

I wanted to upgrade my home theatre speakers, I finally decided on the Polk Audio RTI A7's.  Whilst these were ok, I didn't quite like the bright mid range/treble. Luckily through a search on E-Bay, I found Trey.  My experience with Trey is outstanding.  I constantly recieved picture updates and emails, ensuring that I was always up to date with the progress.  I received the crossovers and they were quite easy to install.  Fired them up and WOW, the difference between old set up and new is no comparison.   There is approx. 140 hours of running the crossovers in and with that cannot beleive how much better they sound over time.  The mid range and treble is now a pleasure to listen to as it is a lot warmer.  The base is much tighter.  I  highly recommend Trey and his crossovers for any speakers. - Mark (RTiA7/CSiA6 Fortress Plus)
