#81 Polk T15: $149.00 per pair Amazon eBay
Pros: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Measured bass extension of 88.6Hz (-3dB), with a measured sensitivity of 89dB.
Cons: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”
How it compares: Just above it: JBL Control 1 Pro - $91 more, 2Hz lower bass extension (-3dB). Just below it: Definitive Technology ProMonitor 1000 - $100 more, 3Hz lower bass extension (-3dB).
