My EP800v4BSGG is smoothing out very nicely now; I can actually use the Gin Gut-punch with more varied music and not blow the windows out, it's just sounding like a live band in the living room.

I have been testing the Parasound Class D amp with 600 watts per channel over the past week and it's adding a lot to the system at the Model T's, its pretty intense to be honest. Almost too much, I had to dial down the bass in the main speakers.

I find the 800 to be very musical, it's just perfect and far better than the 5 other subs I have had over the past year. The only sub which I think is as good is my EP 500 which is very similar in sound performance, but obviously lower in output with a single driver, smaller cabinet and less power; but keep in mind, it's not a small sub in the least. In fact it's large by sub standards.

I'll have more to report after more use and break-in time.
