I have no reason to believe they won't other than that they are sold as HT speakers, which generally has different requirements. I need to know they will do well in this regard.

Both the Paradigm and B&W speaker sound very good, but they sound like you are listening to a very nice home sound system. The T8's sound like you are at a concert without giving up any of the details from the other brands. At lower volumes the difference is not as noticable, but as you turn the volume up the T8's continue to sound crystal clear, while the others start to sound harsh. You just can not get the big sound that the T8's deliver out of any other speakers I have heard. By the time you get that wall of sound feeling with commercial speakers, everything sounds harsh, loud and uncomfortable. I have been spending a ton of time listening to music since I got the T8's because it is so enjoyable. The other nice thing is that my wife lets me watch movies around -6 when she always used to complain it was too loud when it was around -13 with my old speakers.

I'm going to give it a try just because I can't get control over this insulation. It seems to have a mind of it's own. I've took the drivers out to tuck the insulation back into place in attemp to get some room between the insulation and the sloted ports. The next day it's right back blocking the ports again and I also have little pieses that break off and get caught up laying in the ports and are a pain to retrive. The insulation is glued to the back of the cabinet but because it's so thick it tends to block off the ports when it exspands back to size.

Any day now I should have the supplys needed to treat the speakers plus my sound card and mic for rew and should arive at the same time I hope. I'm going to test both a treated speaker with acustical foam and a stock speaker with insulation and see if there is a diffrence in performance and sound. This should be cool to see if there are any diffrence in the grafts?

One thing I noticed there is no insulation in the middle of the cabinet behine the coax mid range and tweeter. Is there a reason why this area was not treated jeff? I'm thinking dureing R@D you must of tested it both ways and found it to be better not treated. Pleas post your reasons why I should not treat the middle section please.

The middle section is open to the woofers from top to bottom so it seems it should be treated like the rest of the cabinet to reduce resonace and give better detail highs and midrange and overall sound?

I was only planing on replace the insulation with foam but now I'm thinking of doing the whole cabinet to see if there is any inprovement.

In search of makeing my triple 12s the best they can be. My triple 8s will be next to be treated if the acustical foam sounds good.


Thanks for any feed back Jeff

Do you think this switch would be an upgrade:

Current rig:
Paradigm - studio 60 v3, cc-690 v4, adp-590 v5
Onkyo 805 (just 130w)

Option 1:
JTR - Triple 8 r/l fronts (Phantom center - fronts are only 4 feet apart, seating is directly in sweet spot)
Side - Emotiva ERM1's
Amp upgrade - Possibly ep2500's bridged - Cautious about the noise.

Option 2:
JTR - Quad 8's (same phantom center)
Sides - SVS SBS-01's
No amp upgrade yet.

If you really want the Quintuples, I would recommend taking advantage of the preorder sale and either leaving your current surround speakers in place or moving your current fronts to surround duty. Your current fronts are likely to be a bigger upgrade for your surround speakers than the surrounds from the two companies you mentioned. I do not know if your room layout will allow this.

The Triple 8's I have image very well. I have to check often to make sure I am really just in 2 channel mode and do not have the center speaker going when listening to 2 channel music, but a reasonable choice would be to go with 3 JTR's of either type and wait on everything else.

You will do fine with your Onkyo. I ran my Triple 8's off of my 905 and blasted music and movies at reference level without any issues. It sounded great. These speakers do not need that much power to do well, there is no need for an upgraded amp.

I have a related question for Jeff or anyone else who owns JTRs with the textured black finish. Is this finish truely black in color or dark grey? I've owned "textured black" from another vendor previously, and it appeared more dark grey than true black in color; especially in direct sunlight.

The shade of Q8 black will not be a show stopper for me, but the speeaker will be going in a maple cabinet with a lot of deep black trim so a true black Q8 will integrate better cosmetically. FWIW, I'm aware of the maple option for the Q8, but I prefer black for several reasons I won't bore readers with.

Thanks.

What would be the major difference between the Quintuples and the 2010 T8's or T-12's. After reading a thread on your forums, one of the only performance differences I noticed was that the Q8's would extend your minimun listening distance or position.

Besides asthetics (and two more 8" drivers), what could we look forward to SQ wise that we would not get from the T8's or T12's.

I understand that there are a lot of setup variables that can affect things, but lets just assume all three speakers (Q8, T8, T12) were powered properly. Would the only difference in SQ be output? Or would their be different characteristics of the sound.

I hope I am making sense!!!

Also consider I plan to run a phantom center because the fronts are only about 4 feet apart. Would the additional clarity or depth be needed for that installation in order to display with sound of the center accurately?
