Mirage M7si V Def tech BP 20


Has anyone ever compared a Mirage M7si to Def Tech BP 20??. The BP 20 has grown on me as it has very clear lifelike images with an even tonal balance., not to mention the large stage. Many speakers that have very clear images tend to be thin or bright. There is some actual meat to the images on the BPs. I would like to try a pair of Mirage M7si but based on items I have read they may be a little thick and not as transparent as the BPs.

Mirage's M_si series is great. The M7si is OK but from the M5si on up they're awesome! I've had miy M5si's for almost 19 years now and have no intention of swapping them out. An excellent condition used pair (when you can find them) run $500-700 and are the bargain of the decade: the midrange intimacy of a mini-monitor with the room-filling power and bass extension of a big floorstander. Mine are near linear down to 29 Hz and audible to 26.

I bought mine for half price when Magnolia was dropping the line in 1996 and replacing them with Def Tech. It was a commercial--not sound quality--decision. The sales people I talked to there were sad to see Mirage go because they knew it was a better speaker. At the time Def Tech was launching with a high budget ad campaign and had more buzz and visibility. That doesn't mean they were better.

In fact, Def Tech's bipolar implementation missed the point according to Mirage. Mirage had purposely made the speakers wide and shallow to make them as near omni as possible. When Def Tech went narrow and deep, it separated by front and back drivers by more than a foot, and created a bigger void in the side radiation pattern.

They also make for good headphones. If you've never tried it, play some music and go over to one of the speakers and stand facing the thin side. Move forward and touch your nose to the cabinet and it will sound like you are wearing headphones.
I agree with Johnny, the M5 si is the best starting point in this line. The m5 si lasted longer than any other speaker in my system, 12 years. They do many things very well and some day I would like to revisit them. Of the M si series only the 5 si and 1 si were true bipolar speakers. The m3 si is a terrific speaker, though. All of them like lots of power and need to be well out into the room to be at there best.
