#26 Seeburg X8: $2,169.00 Thomann eBay
Pros: Bass reaches about 69Hz (-3dB) in vendor Spinorama data, and the coaxial 15-inch design claims 134dB from a 22.5kg cabinet. Preference scores of 3.33 standalone and 6.14 with an ideal subwoofer come with a coverage pattern that stays consistent around the horn. Measured bass extension of 69Hz (-3dB).
Cons: Listening-window narrow-band deviation is 0.571, the worst in this ranking, so the midrange response is noticeably uneven. It is a passive cabinet that needs an external amplifier and processor, and the price is high next to powered 15-inch alternatives.
How it compares: Just above it: FBT J15A - $1109 cheaper. Just below it: Martin Audio XP15.
