#115 JBL Synthesis SK2-3300: $20,000 per pair Discontinued eBay
Pros: A THX Ultra2 left, center and right speaker with two 10” Alnico woofers, a 3” beryllium compression driver and a 1” beryllium ultra-high-frequency driver on Bi-Radial horns. Sensitivity is 93dB. Measurements show a preference score of 4.41 that reaches 6.9 with an ideal subwoofer, with 0.28 listening window deviation. Measured bass extension of 66.6Hz (-3dB).
Cons: It was sold through JBL Synthesis dealers and is no longer in the lineup. Bass reaches 66.6Hz (-3dB) and about 51Hz (-10dB). That data is low quality. Discontinued.
How it compares: Just above it: CSS Criton 1TD-X DIY - 6Hz lower bass extension (-3dB). Just below it: Aoshida Audio Musician Knight I V2 - $7901 cheaper, 4.3Hz lower bass extension (-3dB).
