Any info on these? I bought a pair in very nice condition at my local thrift today for $20.00.
When were they made? Original cost? Not much info on the Web.
They sound pretty good with my Dynaco ST70.Gonna try my Hafler 220 next.I think they could use more power than the Dynaco.Thanks!

That's a great buy for $20!They were part of Dahlquist's moderately priced line in the mid to late 1980s. They were the second from the bottom of a four speaker line; M903 (small bookshelf two way), M905, M907 (larger three way with I believe a 10" woofer) and M909 (larger still; I believe still a three way). The M905, M907, and M909 could be combined with the Dahlquist "ST-9" stand which had wood veneer to match the finish of your speakers. I have a set and they are handsome.
According to the press materials, Dahlquist used special internal cabinet bracing, flush mounted all the drivers, carefully engineered the crossovers and added the special flocking on the front surface to decrease the "boxy" sound common in mid-priced speakers of the day.
I purchased my set brand new in 1988 for $590 for the pair. At the time, I was considering the Spica TC-50, Design Acoustics PS-10, and a B&W speaker which were all in the general price category. Of course, the Spicas had the nicest soundstage and largest stereo imaging, and the B&Ws had the deepest bass, but the Dahlquists were not far behind either. I use mine with a powered subwoofer and one of the Dahlquist DQ-MX-1 passive crossovers with very nice results, I think.
Parts are generally available from Regnar, a company made up of some former Dahlquist engineers and/or employees. They even sell (or sold) a crossover upgrade kit. I have never dealt with them so I can't share any experiences. They are on the web.
I actually just moved and the owners' manuals are still packed. If you'd like some of the technical specs, send me an email and I'll get more info for you in a few days.

Thanks for the Info! I have not had a chance to try them with my Hafler yet. I think they will sound very good, with some power. Any idea what their power handling is?
I'm not sure about the power handling, though they are pretty efficient and you won't need a ton of power to drive them. I have used them with a Nikko NR-750 receiver of about 48W per channel, a Nikko NA-1050 integrated amp of 105Wpc, a NAD integrated amp which I can't remember much about, and now a late 80s Sony TA-F700ES which I think is also around 105W, but has much more dynamic power than the either of the Nikkos. I have found that these speakers seem very happy with something in the 100 watt range.Of course, each driver is protected by a fuse which should take some of the worry out of experimenting with different amps. I blew one of the tweeter fuses within a month of getting the speakers back when I was a foolish kid.
I would be interested in hearing whether the Regnar crossover improvement kit makes a difference in these speakers. The rest of the speaker should be pretty low maintenance since the woofers used a butyl rubber surround.
I have dealt with Regnar while pursuing a total restoration of my DQ-10's & DQ-MX1 X-over. I also have the DQ-1W sub, however, this needed nothing but power. They are top notch when it comes to quality and Joe is very informative and easy to talk to (and this is coming from a guy from CT-we usually have a hard time dealing with New Yorkers in general). My experiences are very favorable. However like anything else in higher end audio AND Long Island, dont be bashful about breaking out your wallet if you decide to upgrade. With my DQ-10's the money is gone, but the sound and reliability isnt!
