Help- why do my Definitive Tech BP7001's sound Bad

About a year ago I purchased a brand new pair of Definitive Technology BP7001SC speakers. The problem is I am not satisfied with the sound I am getting from them. They sound good (but not mind blowing) on some recordings such as Diana Krall’s “Girl in the Other Room” and James Taylor’s “Hourglass”. They even sound good on some earlier remastered recordings like The Band’s boxed set. But for many recordings (more “rock” oriented with lots of guitars and layers of sound), Cd’s and LP’s, they sound harsh, fatiguing, and the mid range is flat and muddy. My other complaint is on many recordings the vocals sound “buried” in the mix- not as prominent as they should be. I am running them off a Denon 3805 (120 Watt per channel) receiver. This was one of the top Denon models a couple years ago (replaced by 3806 I think). Receiver was highly rated and seems to work fine. I listen to mainly music and do not yet have surround sound, so I am talking strait 2 channel stereo here. I know a lot of audiophiles say Def Techs are not great for music only but I have also read many glowing reviews of the 7001’s for music applications. I am thinking my room may be part or all of the issue. The room is full of hard surfaces- pergo floor with area rugs, sheetrock walls, not that much furniture, no drapes, etc. The dimensions are 27 x 18 feet with a 14’ high cathedral ceiling. The system is situated on one end of the 27’ wall (1 speaker near corner of room), speakers about 9 feet apart and angled slightly in. The main listening area is about 15-16 feet away (alone the opposite wall) and centered on the speakers. Actually my biggest praise for the speakers is how relatively GOOD they sound in all parts of the room. But they don’t sound that GREAT even in the prime listening spot. I have tried facing the subwoofers out vs. in and this does not seem to matter. I have also tried moving the speakers closer and further from the back wall and changing the angle, and this has not cured anything either. Right now they are about 14-16” from back wall. I currently have the speakers connected with 14 gauge speaker wire thru the “mid range/ standard” hookup method. I tired the subwoofer LFE hookup and this makes no audible diff for music. Overall, they just don’t have the WOW factor I was expecting for the price. I actually never heard them before buying. I did audition the smaller 7002 in the store and liked that so figured the 7001 would be even better. And for half price I could not pass them up.

So what do you guys think:
Are the speakers just crappy for music? (how can a 3500.00 speaker by crappy?)
Would bi-amping help the sound to any great degree?
Is the shape of my room the problem, particularly with the bi-polar config?

Any thoughts would be greatly appreciated!!

The DT's lack in areas of detail, resolution and transparency. But, if you have good synergy with your amp the 7001's, and the front end, they can do well enough on music too. Aside from possible room issues and 1st reflections, it sounds like your current setup lacks synergy. I had the 7000's and my setup lacked synergy as well. I ended up selling them to another guy and he loves them. My first thought was that his system is totally different than mine and they perform better in a different setup because of better synergy. Although I never got mine to sound as good in my room as the dealer's pair sounded, I think if you add different electronics and front end, you will do much better sonically. Take some of your favorite music into a dealer and listen to their 7001's. If your music sounds good on the 7001's at the dealer, you may want to try buying the electronics and front end the dealer uses. Def Techs are really HT speakers as most will tell you, but they can do well enough with music, especially rock. Your room needs work with first reflections, but a lot of your problem sounds like a lack of system synergy.

Yeah, it's the room/speaker interface. See my review of the Sumiko Master Set at:
http://forum.audiogon.com/cgi-bin/fr.pl?rspkr&1197744079&read&keyw&zzsumiko

If you've ever been to a large audio show, you'll notice that most of the speakers, no matter their cost, sound like pure crap. This is usually due to the speaker set in the room.

The speakers must interface with the room and work in concert with each other, producing equal sound pressure levels, in phase and in time. If not properly set you'll sense intermodulation distortion as hardness and fatiguing glare, no matter how good the speaker is.

Find a Sumiko dealer and beg him to let you pay him to set up your speakers. (All Sonus Faber and Vienna Acoustic dealers in the USA are dealers of Sumiko products).

After the speakers are placed, you may or may not need a little room treatment, particularly if you have first-reflection issues from the floor or side walls. You won't know that until the speakers are in their optimal places.

Sorry for stating the obvious......but I must agree with others, Defs won't give you "awesome" -at least not for music. You are faced with a very tough choice...........

I would second the better amp and pre or better integrated amp. Also don't know if this is possible with your room but try to create a symetrical triangle with your speakers to the listening position. Meaning if the speaker are 9' apart the listening position should be 9' from both speaker and toe in speakers so they come right accross you shoulders. I use a laser pointer to do this. Try to treat the room some. Natural treatment work to, furniture, book shelf to name a few. How far away from the wall have yougot them? I some of the same problems when I was moving my placement around. those problems were experience most when to close to rear wall but also noticed some with to close to side wall.

CJMBLM,

I have the 7004's and was initially driving them with a Yamaha receiver...For music they sounded just ok...I then added an Adcom amp and used the Yami as a pre..Huge difference in soundstage, clarity etc. Agree with others who say look at your room also.. The def- tech bipoles do not work well in corners and first reflections points should be treated appropriatly. Room treatments will make a big, big difference..Just and fyi...Have you checked the settings on your receiver. Make sure fronts are set to "large". Also, play with the volume setting for the subs. Inproper setting can muddy the sound "especially" with alot of reflective surfaces....Last but not least...The recommended breakin for your speakers is 60 hrs min.
