#135 KLH Model Four: $1,999.98 per pair Estimated Amazon eBay
Same family: the KLH Model Three (bookshelf, estimated 3.8/5), the KLH Model Five (larger floorstanding, ranked higher, rated 4/5) and the KLH Model Seven (larger floorstanding, ranked higher, estimated 4/5).
Pros: A slim floorstanding member of KLH’s Model collection, with an 8” woofer and the same 4” midrange and 1” aluminum tweeter as the measured Model Five (4.76 Spinorama preference score). The sealed cabinet is only 210mm deep and can sit 6 inches from a wall. KLH rates it 46Hz to 20kHz (±3dB) and 35Hz at -10dB.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Model Five. Free-field sensitivity is 85dB and the impedance falls to 3.5 ohms at 120Hz, so it needs more amplifier power than its size suggests.
