QSO 626R
"The end result is simply put: sheer madness!"
- Dick Olsher
April 2001 saw the introduction of the QSO 626
Ribbon, a rear-ported three-driver design of the highest available sonic quality.
Indeed the 626R is perhaps the best-sounding small system you can buy, despite its low price (for which we
apologize - compare the 626R against those $10,000 minimonitors and hear what we mean). The 626R
fetures our exclusive Neo midrange panel, with
new FST ribbon tweeter with flat response out to
25 kHz.
Cabinets are 61 cm tall, slender (25 cm wide), and feature round vertical edges, flush mounted drivers, and slotted antidiffraction masking of the tweeter for optimum dispersion in either the horizontal or (with masks rotated 90 degrees) vertical planes. The ported woofer design delivers high power handling and bass extension heretofore unheard in this price range (-3dB at
42 Hz / 1 W drive, no more than 5% THD, with port output clean to 35Hz).

How to get the most out of the
62R's
1. Break in for 100 hours. We do 24h at the factory.
2. Use a solid or baffled stand that puts the
upper part of the mid panel at ear height.
3. Once 1 and 2 are taken care of make microadjustments of the level controls for maximum clarity. Factory settings are about 1:30, but on your
equipment may be that 1:15 for the mid and 1:45 for the tweet are ideal. You'll soon find out.
Your CD's, both bad and good, will sound a lot better when you'r done.
How to improve your
stand
1. Make sure it is the right height. Usual stand
height of 50cm may be OK, but might be taller or shorter for
you, depending on your height and/or your seat
height.
2. Add weight. A steel sheet on the stand on the speaker, weights on top of the speaker, sand in the stand frame.
3. Add a baffle. A "beard" installed on the front of the stand, top to floor, vastly improves the sound. Almost any material will work, even cardboard.
It's puzzling that manufacturers turn out open frame stands at all. The cavity below the woofer destroys bass response, as Paul Klipsch pointed out 35 years ago. Adding a front baffle the same width as the speaker and extending from the top of the stand to the floor gives the bass a boundary to travel along and increases efficiency below 100Hz up to 6 dB.
