The Two Speakers In Full
JBL Studio 698: $1,499.90 per pair Crutchfield eBay
Older model: the JBL Studio 590 (ranked lower, rated 2.8/5).
Pros: High-Definition Imaging (HDI) horn waveguide paired with a 1” compression driver provides excellent high-frequency directivity control and seamless acoustic handoff to the 6” PolyPlas midrange. Dual 8” PolyPlas woofers deliver robust low-end authority with solid bass extension down to an F3 of 53Hz and F10 of 34Hz. High voltage sensitivity (90dB SPL at 2.83V/1m) and clean power handling provide effortless dynamic headroom and low distortion for home theater and music listening. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 90dB.
Cons: Measured response exhibits a prominent mid-bass emphasis bump around 80Hz that can sound overly thick or chesty in smaller rooms without DSP EQ. Treble response lacks top-octave ‘air’ above 12kHz compared to high-end dome or ribbon tweeters. Physically large, heavy cabinet (35.8 kg per speaker) requires careful room placement and a wide acoustic footprint.

JBL HDI-3600: $3800 per pair Audio Advice eBay
Pros: CEA2034 spinorama shows a fairly even on-axis response and flat overall frequency response, with high 90dB sensitivity and very low distortion through the midrange. Triple 6.5” Advanced Aluminum Matrix woofers and a 1” compression driver in JBL’s HDI waveguide. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: A wide shelving-down above 2kHz affects the in-room response, and vertical dispersion is a bigger issue than horizontal: the reviewer noted the dip is wider here than on the smaller HDI-1600, making it more audible. Narrow vertical sweet spot means careful listener-height positioning matters more than usual.
