Genelec 7050C: $1,575 B&H Photo Video eBay
Older model: the Genelec 7050B (rated 2.7/5).
Pros: 8-inch (205mm) driver with a 130W Class D amplifier. Genelec rates it at 24-85Hz (-6dB) and 103dB maximum output, with 6 balanced XLR inputs and 5 outputs for bass management of a multichannel system.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. There is no automatic room correction, and 103dB maximum output limits it to smaller rooms and nearfield studio use.
