Haven't had much desire for new gear since I got my amazing Seaton SubMersive a year and half ago - it effectively cured my upgraditis, at least for subwoofers (I had gone through an SVS PB12-NSD, dual HSU VTF-3.3, dual PB13 Ultras, and an Epik Conquest before finding sonic bliss with the SM). I've been pretty happy with my Rocket 850/200/450 setup for 5.1 HT but have remained very curious what improvement if any the JTR speakers could provide, and yesterday I could not resist buying three barely used 2010 Triple 8HT's to try out as the front stage. I've enjoyed the aesthetics of the rosewood Rockets but if these JTR's live up to even part of the hype I suspect I will learn to live with the truck bed liner finish.
The Rockets have performed well for HT. After living with them for 2 years I would say that they remain really good value for the dollar (all 5 speakers for about 2k), but from everything I've read with the Triple8's I expect more detail in the treble (Rockets seem rolled off and laid back), more sense of effortlessness and dynamic headroom when played at -5 from 85db reference or higher, and I'm hoping for a bit more authority in the 80-160hz range (most label this upper bass). Right now my crossover is 100hz for all five Rockets because the SubMersive has more dynamic power in this range, but I expect with the Triple8's I will go down to 80hz.
The room is 2500cf sealed (but leaky with lots of windows and glass-paned doors), treated with 6 GIK TriTraps and 3 panels and has heavy fabric chairs, curtains, and heavy carpet and pad, so there is little to no echo or ringing. Source is almost always Blu-ray movies with lossless sound on the Oppo BDP-83 with a Denon 3808 as pre/pro and power from an Earthquake Cinenova Grande.
I should have the speakers in hand a week from Friday and will post impressions and comparisons to the Rockets.
