#128 JBL 4319: $4,000 per pair Discontinued eBay
Pros: High sensitivity around 90dB and controlled bass distortion mean the large 12” woofer plays loud with copious bass and modest amplifier power needs. Impedance dips are well controlled, so it isn’t a hard speaker to drive despite its size. User-adjustable midrange and treble level controls are built into the back panel. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: CEA2034 spinorama shows a pronounced 800Hz dip and a comb-filtering pattern in the woofer response consistent with a delayed reflected source, plus poor and uneven vertical directivity. The reviewer described the sound as “boxy and closed in with some brightness” and could not recommend it “unless you like looking at it more than listening to it.” At 23.5” tall, it’s closer to a small tower than a typical bookshelf speaker. Discontinued.
