Home Speaker Asylum

General speaker questions for audio and home theater.

RE: Dahlquist DQ-20i

You scored some great speakers.

When I had them in my system, I initially drove them with a 100 watt Yamaha receiver. The sound was pretty good, but I didn't know what I was missing until I replaced the receiver with a high current amp (Parasound HCA-1501a and McCormack DNA-1). Things really opened up with more power. They didn't even sound like the same speakers. The bottom end was much more powerful. I couldn't go back after hearing the difference.

The Outlaw RR2150 might be a good compromise if you have your mind set on a receiver. Stereophile wrote a favorable review in 2006. Here's a notable quote:

The Outlaw RR2150 exceeded its 100Wpc specification by 1dB, delivering no less than 125W into 8 ohms (21dBW) at clipping, defined as 1% THD. It gave 190W into 4 ohms (19.8dB), this is 0.8dB higher than the specified 160W, and even managed 310W into 2 ohms with one channel driven (18.9dBW). That this $600 receiver managed to survive this high-power testing without blowing fuses or anything breaking is high praise. The RR2150 is a powerhouse!

Make sure to check the foam surrounds on the woofers. They have a short life span. If they show any signs of deterioration, refoam them. It will help the lower end tremendously. Simply Speakers sells a kit for $27:

Here's a video of someone doing the refoam on a pair of DQ-10:

For what it's worth, here are the DQ-20i specs from the owners manual:

Frequency Response:
20 Hz to 20 kHz +/-4.5 db
50 Hz to 20 kHz +/- 2.5 db
1 kHz to 20 kHz +/- 1db
Power requirements: 50-250 Watts
Impedance: 4 ohms minimum (6 ohms nominal)
Sensitivity: 86 db/1 meter/2.83 volts

Have fun and enjoy!
