This is pure trivia, nothing of real technical or audio interest, but it's mildly amusing. I recapped a pair of KLH 23s, which had never been opened since being built, I am sure, and as I lifted out the insulation I saw that the person who assembled the speakers left a cotton glove with a piece of masking tape on it, and a hole in it, in the corner of the speaker. It looked like the glove was shot, the worker was were tired, and just decided to contribute the glove to the insulation in the speaker. Or, they lost it and didn't know where it went. I left the glove where it was when I re-assembled the speaker.
Compelling AR "Hindsight" Questions: Instead of the 3-way AR-5 with its excellent, expensive midrange and tweeter, should AR have made a good 3-way bookshelf unit using the AR-3a 12-inch woofer and an AR-2ax-type midrange and dome tweeter—at the AR-5 price point—to better compete with (or outgun) the Large Advent? It would use the AR-3a-size cabinet, but it would not include the expensive midrange-dome driver or solid-wood grill molding. It would look like a slightly larger AR-2ax box. As we all know, the AR-5 was (except for deep bass) technically superior to the Advent, but it failed in the market place because of its lack of low-end "punch" and its relatively high price. The AR-3a was definitely (and technically) superior to the Advent in deep bass, but it cost nearly twice as much. Therefore, would a watered-down 3-way, using the heavy AR-3a woofer, been the answer? Another angle: perhaps a 2-way design with a redesigned, Advent-like 10-inch woofer and a new mid-tweeter, capable of a lower crossover? By the time of the AR-14, these things were seriously contemplated, but it was too far down the road to try to catch the Advent's sales advantage. The AR-14's bass fell squarely between the AR-3a and the AR-5. Another angle: should AR have designed the AR-5 with the AR-2ax's cone midrange and dome tweeter, but a more-potent, lower-resonance 10-inch woofer that would be equal to the Advent 10-inch woofer? This woofer would have the same low-resonance response of the Advent, but it would lack the extremely low distortion, potent output of the bigger AR-3a 12-inch woofer. Each of these designs might have cost less than the original AR-5, but looking back, hindsight is 20-20. Would any of these designs been the answer in 1968? Thoughts... comments? —Tom Tyson
