Used these for 10 years with an MB Quart Center stage for my home theater. Great speakers, excellent lows and smooth response through to the tweeters which are great. Enough bass so didn't use a sub.

Center speaker doesn't have a flat top, it slopes down to the back.

i have a set of d 55s
but i have a problem... and hope mayb one of you can shed some light...
one of my tweeters are blown. 1 tweeter does not work on either speaker.
i just can't find a replacement. can it be replaced or fixed, or does anyone know?
PLEASE PLEASE HELP ME>!!!

After lengthy consideration of which front speakers to buy, I settled on the D55's. Just for comparison's sake, I also considered B&W, Mirage, Martin Logan, and Energy. The D55's outperformed the rest of the competition for a median price. The Logans were entirely overpriced, although they were nice to look at. The domain 1" tweeter creates clear, crisp high range with little audible distortion, and the two 6" drivers handled the bass without any problem at all. These speakers were unbelievable at first purchase, and more so after purchasing the CTR stage timber-matched center channel and balcony surrounds. One word of caution, the impedance on these is 4 ohms, so make sure the whatever amplifer you are powering this with is comfortable at that level. I am currently using a Harman Kardon Signature Series amp and preamp, which were pricy but well worth the money. The effortless reproduction of true-to-life sound, PARTICULARLY in stereo music listening was quite impressive, and all I could ever ask for in a full-range cabinet. The bass-reflex enclosure helps the efficency of the bass, so don't let infinity tell you otherwise. Previous to owning this set, I had a set of B&W 600 series in the front and back, but these easily outperformed them, and even B&W's higher priced line. I give these speakers a 5-star rating due to the clear reproduction throughout the full range of sound. The domain line has since been discontinued, but MB Quart has re-released this line as the "C" line with the same specs and design with only cosmetic differences.

I agree with Adam on the MBQuart Domain 55. When I first heard these I was amazed at how dynamic and natural sounding they were. Instrumental timbres were reproduced accurately, the imaging was fine, and the bass was full and well defined. The salesman in the store said they used the Quarts whenever they demoed CD players or receivers because "they make anything sound good". And, yes, the tweeter is a killer. Recommended. And if you can still find them for $400, a total steal.

I agree with Adam and Frank. I purchased a set (yes I got the 400.00 steal) because of my previous experience with another fine speaker from MB Quart - the 350S. I was looking for the same sound the 350's had but with a little better bass response. The D55's were amazingly clean in that respect - I love the "low end" from these speakers. It's very tight and very smooth and I was actually able to take my sub-woofer completely out of the system with no loss of listening pleasure. The mid-range and high-end was everything I had expected from Quart's titanium domes. Soundstage is quite large and very well-defined and imaging is superb. Are they electrostats? No, but in a medium priced (read: affordable) speaker, they are definitely better than most others in that range. I had recently demo'd three different models from Mirage and two from Celestion and dollar for dollar they outperformed them all. I haven't replaced my 350S with them yet (I have grown extremely fond of those little guys) but overall I'd give the D55's 4 stars if you pay full price and 5 stars if you can get the 400.00 deal!

Update to my review below:Before I got the D55, I had listened to Infinity RS4/RS5, Polk RT12/RT800, Klipsch KG 5.5, KEF Q50/Q55, B&W 603/604, JBL HLS 820, AR 310HO, Snell Type D, and Jamo 128. I like the D55 better as far as price/value is concerned.

I got a pair of MB Quart D55 recently. I used them as front speakers with a pair of KEF Q15 as rears and a PSB Alpha Subsonic subwoofer. The sound of this system is incredible to me. The more I listen to the D55, the more I love it. I don't know how the sound is so clean, so warm and neutral. The bass is amazingly tight and powerful for a 6.5" driver. With the addition of the Alpha Subsonic, you can hear and feel virtually all the low ends. A lot of time I have to shut off the sub in order to prevent my windows and walls from shaking, but I am still pleased with the "remaining" bass from the D55.

The Domain 55's are probably the best value in speakers under the $1500 price point. I work in an electronic store and picked up the last set for $200 because they were discontinued and because of my employee discount. we used to sell them for a $1000 a pair, and they were well worth every penney. The tweeters are the real high point of the speakers made of titanium and used in multy thousand dollar speakers(of other names) because of M.B. Quarts superior design. I use them for stereo use powered by an Onkyo Integra amp, but will work just as well for home theatre applications. A superb well balanced speaker if you can still find a set. Fact is I like them just as much as my Infinity Kappa 8.1's which retail for more than double than the M.B. Quarts's original price!! Unquestionably 5 stars!!
