unsound - I agree. I don't know why Jim designed for such low system impedance. I can speculate that marginally lower distortion in the driver motor may be had via lower driver impedance . . . BUT all the amplification problems caused by low impedance are a huge negative factor in system performance. As I've mentioned, he called those problems "amp problems". I don't know enough to speculate meaningfully. |
there is a lot of valuable and useful tips on the Mapleshade website. here are two that are relevant to the post above: http://www.mapleshadestore.com/freeupgrades.php Room Set-up & Speaker Placement Try Near Field Listening Almost everybody sits way too far from their speakers, that is, 8' to 10' or more. Try a low chair (or floor pillow) 5' away. You’ll hear a phenomenal increase in clarity, bass impact, and soundstage—roughly like spending 100% more on your speakers. Sitting close (aka near-field listening) tremendously reduces all room acoustic problems and the need for expensive room treatments. Sit Low To The FloorNearly everybody sits too high. The "tweeters at ear level" rule sounds logical but almost always fails when tested. Every speaker has a different optimum listening height; if you’re off the optimum ear height, you’re not getting your money’s worth. Test by sitting on one, then two, then three phone books on the floor at your normal listening spot. At the optimum height, you’ll hear an amazing new warmth and fullness in baritone voice, trombones, tenor sax, plucked bass—and a far more natural treble balance. |
