Fellas,
I just wanted to publicly say "thank you" to Brian and DaveF. I recently purchased a pair of D15SE's through Ascend, and one of the amps had a broken switch from packing or shipping -- I contacted them and they sent me a replacement amp quickly, answered all my questions about swapping it out, and paid for the return shipping. It was quick and painless (except for a delivery snafu on my end that delayed things for a couple weeks....long story! Brian - on that note, I apologize it took me so long to get the amp back to you ).
So, I just wanted to say "Thanks." It may be said very often around the forum, but the customer service 'round these parts is excellent.
Oh, and yes, the subs are flippin' amazing . More depth, breadth, detail and presence than I've ever known from my UFW-10s or VTF-3 HO/turbo. I liken the audible differences to the distinction in driving dynamics between a Toyota Tacoma 4wd and an Infiniti G37S. It's immediately noticeable. Note I LOVE my Tacoma, so that's still praise for my beloved UFW-10s and HO...
Totally different sub price ranges, but the D15SEs are one of best upgrades I've made lately. Fallout 3 can be downright nasty with these things.
