#26 JBL HDI-3800: $5,000 per pair Discontinued eBay

Same family: the JBL HDI-1600 (bookshelf, rated 4.2/5), the JBL HDI-3600 (smaller floorstanding, ranked lower, rated 4.3/5), the JBL HDI-4500 (center, rated 3.7/5) and the JBL HDI-1200P (subwoofer, rated 3.9/5).

Pros: A horn loaded tower with three 8 inch woofers, deep bass, high sensitivity and huge output for large home theaters. 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Measured bass extension of 37Hz (-3dB), with a measured sensitivity of 92dB.

Cons: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate. Discontinued.
