#84 Jamo S 803: $119.99 per pair Amazon Crutchfield eBay
Pros: Low pair price, compact dimensions and a front slot port suit inexpensive desktop or surround installations. The pronounced 80-100Hz hump supplies immediate punch and can sound impressive in a short demonstration. Harmonic distortion at 86dB is broadly typical for an inexpensive 5-inch two-way, and high-passing near 80Hz reduces some woofer-driven midrange distortion. The cabinet also accepts Jamo’s matching top-mounted Atmos module. Measured bass extension of 60.1Hz (-3dB), with a measured sensitivity of 81dB.
Cons: A textbook V-shaped response rather than accurate reproduction. Erin measured only about 81dB average sensitivity from 300Hz-3kHz, far below Jamo’s 87dB claim; bass around 80-100Hz and the treble are each roughly 5dB above that midrange reference. The bass is therefore resonant one-note punch rather than deep extension. Horizontal coverage is only about +/-50 degrees, while the midwoofer narrows before the tweeter widens abruptly, creating a directivity discontinuity that EQ cannot repair around 4kHz. Vertical tolerance is especially asymmetric: roughly 10 degrees above tweeter axis is usable, but moving below it rapidly damages the response. At high output, compression and multitone distortion become audible; an 80Hz crossover helps but does not correct the native tonality. Erin’s conclusion was an unequivocal pass in favor of a more neutral alternative.
How it compares: Just above it: Jamo C 93 II - $179 more, 3Hz higher bass extension (-3dB). Just below it: Klipsch R-41M - $19 more, 4Hz higher bass extension (-3dB).
