#10 JBL CBT 70J-1: $1,480.00 Passive B&H Photo Video eBay
Pros: Independently measured by Audio Science Review, with a 5.87 preference score with an ideal subwoofer and a 3.20 directivity-index deviation. Sixteen 1-inch tweeters and four 5-inch woofers give switchable 25° or 45° vertical coverage for long-throw or medium rooms, with a 131dB peak and a speech or music voicing switch. A pan and tilt wall bracket is included. Measured bass extension of 120.1Hz (-3dB).
Cons: Bass measures 120Hz at -3dB and about 62Hz at -10dB, and the standalone score is only 2.95, so it needs a subwoofer for music. A 4.0dB reference band and 0.573 listening-window deviation mean tonal balance is uneven. It is passive and needs an external amplifier.
How it compares: Just above it: L-Acoustics SOKA. Just below it: JBL COL800 - $903 cheaper.
