QSO 626R
"As for opinions of my friends - all I can say is that I have a living room full of bodies knocked out by the sound!" - customer from UK on soundcoated standard 626R.
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).
Specifications Bass: - 16 cm (6") WCF Megawoofer bass, rear reflex loaded Mid: - rectangular 10 x 20 cm (4 x 8") Neo ribbon, 280 Hz - 6.9 kHz Treble: - FST, 6.9 kHz - 30 kHz Impedance & Sensitivity: - 8 Ohm (5.6 min.) 90 dB/1W/1m Power handling: - 150 W rms /4 Ohms, 20 W min. Frequency response: - 42 Hz-25 kHz +0/-3 dB Dimensions & Weight: - 61H x 25W x 33D cm, 18 kg (24"H x 10"W x 13"D, 40 lbs) Output levels and distortion: - max. 1% THD fullrange / 1 W, max. 110+ dB SPL / 1 m Finishes: - standard lite oak, dark oak. Optional MLS rosewood, macassar ebony, maple, piano black
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.
