You may want to check out the Accugroove Robusta or Latte. The Robusta is a little more raw than the Latte but both are pretty HiFi. I use to run my CLR with a Xitone cab that had a Eminence Beta LTA in it as a sub. The Xitone is powered by a Matrix GM50 which is really made for guitar and the LTA is a unique speaker that has a whizzer cone versus a tweeter. This combo sounded so good but I eventually replaced it with the Latte. I had been using a Latte but when the Robusta came out I immediately started saving and it has exceeded my expectations. At 700 watts it moves a lot of air and has plenty of Thump. Here is a pic of my current setup:

The other thing I had to do in the past when using when using PA speakers was EQ out some of the high end. In the early days of the AXEFX, Ultra and AXEII there was always something about the high end that just bugged me and didn't sound right; however, this was mostly solved when I got the CLR. IMO, the CLR is the best FRFR solution for the money.
In full disclosure, you may want to do a search on Accugroove because there are some mixed opinions about the company. I've had nothing but good experiences with them but they are pricey.
