I can't help but wonder, based on experience (albeit none with the Fluance SX series), whether you're just used to sloppy bass. Now, I do not know what is going on in your case at this point, but if what I just said happens to be true, then this wouldn't be the first time that I've seen such a reaction to higher-end speakers, and I've been down that road myself.
It's entirely possible. I actually went by the place I picked up the centers and bookshelves to ask the sales manager his theory or recommendations on my dilemma. He gave me a couple of scenario's, and the above was one of them. He told me, ruling out an actual problem, that in a week after listening to these I wouldn't be able to actually go back to my old speakers, precisely because of the clarity of the T5's, and the fact that quite often a switch takes some getting used to. Fair enough. I also got him to play his floor model T5's so I could compare, and although he didn't have a sub hooked up to his, they sounded fairly similar to mine. Other suggestions were that the binding posts weren't tight, and to try wiring the positive on the top set and the negative on the bottom set of posts just to rule that out as a problem. Check and Check, no difference.
Did you place the T5s in the same locations that had been occupied by the Fluance towers? How far away are they from the front and side walls? Placement can wreak havoc on sound quality, and with bass frequencies there can be "nulls" that develop that room correction systems cannot fix.
They're in the exact locations as the last system. The bookshelves are of course closer to the walls, and their rear firing port surely adds to their base output. The center is under my TV in a cabinet, However it's a large cabinet with no other obstructions, and the center is crystal clear so I don't have a problem with it at all. The difference with the fronts, although in the same location, about 1.5 feet away from the back wall, is that they have a front firing port, as opposed to two rear firing ports on the Fluance. I wonder if this could account for some of the fluctuations I'm experiencing between the two sets of towers?... e.i. the base isn't reflecting off the rear wall as before?
1. Try playing them one at a time (with no other speakers playing) to make sure that they sound the same.
2. or now, you could try raising the T5s up to the same tweeter height to find out whether this makes a significant difference (I do find myself that higher, to a point, sounds bigger).
1a. Yup, I just now tried playing them individually and they sounded the same.
2a. I raised them up, and I THINK it made a small improvement, but then again it might be my imagination!
How much time do you have with the C5 and B5s? We can use that time to troubleshoot your issues.
Well I've got 15 days, but I'll be subject to a 20 percent restocking fee if I go this route, which is 200 bucks straight off the top. So now this is definitely the last resort.
I'm going to re run audyssey and clear my coffee table out of the way this time to see if I get a better response from the fronts.
Ok, Time lapse
I re ran it, and got the exact same settings for everything. Fronts small, at 60hz, center and sides at 40, and surround rears at 120.
It might be worth mentioning that the guy at the audio store told me that my subwoofer sucked, and I should just set the fronts to large and let them handle all the low frequency effect, and get rid of the sub. I tried it, didn't really like it, so the sub stays
. Could be that the sub isn't blending well with the speakers, it's an older Denon DSW 391. It seems to do the job that being said, it's only 100 watts, but I live in an apartment anyways ( albeit with thick walls ). Anyways I doubt that has anything to do with it just thought I'd mention it.
It could very well be in a week I'll be head over heals with this system. That audyssey crossover setting does bother me though.
I did try this test out with my center disconnected, and was able to hear the test tone almost immediately at 20 - 30 hz though: http://www.audiocheck.net/audiotests_frequencychecklow.php
Here's the Image Specs, with the T5 rated at 30hz, lower then all the other speakers, wonder why I'm not getting it ? ( apparently )
One last note... as I sit here at 1 15 in the morning, listening to one of my favorite albums downloaded in FLAC, I'm starting to come around. This album sounds ridiculously good right now...
