Dahlquist DQ-20 Fan club Rant


I just need to say - I have been using DQ-20's for the past 5 years, and recently got the "upgrade bug". So for the past month I've been running around to showrooms and auditioning the latest crop of under-$5,000 Miracle Speakers all of which have glowing reviews, of course. And I've been checking out used speakers that went originally up to $12,000. And you know what - I've given up.

With the disclaimer that everyone's ears are different - I must say that there' justs nothing out there that beats the DQ's (for my particular ears) overall sonically.

There are plenty that have lots of high end zip in the showroom, because they've got metal dome tweeters which will fatigue you real fast at home. Hence so many of the "latest and greatest" hitting Audiogon with bizarre explanations by the owner as to why he's selling 4 month old speakers.
Nobody ever says - "I made a mistake, these suck, but you'll just love 'em. Listen to how real the triangle at the back of the orchestra sounds!"
And there are some that have MORE bass, because they put a big round hole in the cabinet - called a port - that goes, Whoomp, Whoomp, Whoof. (Could somebody let the dog out, please!) To be fair, there are speakers that go lower with good accuracy - but it's nothing that can't be dealt with by adding a pair of quality little subs. And the bass the DQ's do have is tight.
And there are speakers with nicer wood veneers - you want the birdseye maple veneered MDF instead of the cherry veneered MDF - Oh, that's another $1600! Just don't tap the top of the cabinet with your fingernail, you might dent it!

There are NO speakers that I have heard that have sweeter, more coherent, more real midrange and near-highs, period. In combination with my Velodyne ULD, the DQ's can rock, they can do gorgeous vocals, and full orchestra is probably as good as you'll get below $10,000.

There are speakers I've heard that image great, but that is most certainly one of the Dahlquist's strengths, too.

The only thing I truly would wish for in the DQ's is just a bit more zip in the highs.

It's disappointing. I really wanted the fun of some "New Toys", but there is a magic to the DQ's which I assumed was available elsewhere - it's not. My Spicas had it, but they did have much greater limitations dynamically and frequency-wise. I'd have to say that the Vandersteen 3a Sigs were the closest to having that magic and coherency, but not very exciting - and the Green Mountain Continuum 3 was overall the most impressive (but just not quite right for my tastes.)

So what am I gonna do? I'll experiment with the Regnar capacitor upgrade, but I'm not necessarily going to touch the crossovers - that's probably where the magic is coming from. And I'll try a bi-amp configuration. Maybe try a more "modern" Scanspeak tweeter.

And I have this crazy idea to take two pairs, remove the grills, and stack them like quads (on a custom welded rack) with one speaker upside down, so that each set ends up in a D'Appolito configuration. I'd be willing to bet that would be an approx. $1500 set-up that would knock your socks off.

Any other ideas or suggestions out there? I'd be interested in hearing from anyone who's done the Regnar (or other) upgrades. Cheers, Chip

Opalchip, the upgrades make a difference if you know a tech who can tell what parts will make the biggest improvements and what ones to leave alone so that you are not just replacing parts for the hell of it. Try Miller Sound in PA.

Happy Listening.
Opalchip, why don't you let us know how your experiment with stacked DQ20's works out, once you get them dialed in?
Well, I just bought a 2nd pair which miraculously showed up locally just hours after I posted the above rant - and I grabbed 'em. It's possible the seller was exaggerating for "marketing" reasons, but he said he was getting a ton of inquiriess about them (at $450).
Now I have to figure out how to do this. Haven't had time yet - but first I'll just try them side by side with careful measurement of distance to the listening position.
Looking at them from a vertical D'Appolito perspective - they'd be about 7 feet tall. Could be a WAF problem there!
Opalchip, re WAF, suggest shipping the wife off to her Mom for a few days and presenting her with a fait accompli when she returns. Need to get those tweeters as close together as you can, to preserve your good imaging/soundstaging qualities. At least that's been my experience with stacking. Anyway, 7-foot-tall speakers look cool!
Yeah - but her Mom's in China! And 4 DQ-20's with the grills removed - not a pretty sight! This would also have to involve building new 7 foot tall grills, probably by modifying the old ones.

I've gotten pretty good imaging in a side by side arrangement with other speakers. The key there is keeping ALL distances to the listening spot identical, and also keeping the distances and angle of orientation between each "pair" the same. So that'll be the first step just to see whether the whole thing is even worth while.

Out of devious curiosity, I tried last night with one pair 8 inches directly IN FRONT of the other (for lack of space or time to do anything else at the moment). Bass coupling was thunderous but there was definitely some cancellation going on in the midrange. I didn't really expect it to sound like much - but I had to plunk the new pair down somewhere. Overall it was actually better than one would expect.
