Short answer: the Revel F228Be for directivity, the JBL HDI-3600 for efficiency. The JBL combines a flat overall response and very low midrange distortion with high 90dB sensitivity, but a wide shelving-down above 2kHz affects the in-room response and its vertical dispersion dip is wider than the HDI-1600’s, making it more audible. The F228Be is essentially flat on-axis with very nice directivity, though it dips to 3.4 ohms.
Buy the Revel F228Be if sound quality is the priority over the price, or the JBL HDI-3600 if the price is the priority over sound quality.

Revel F228Be: $9,000 per pair Crutchfield eBay
Older model: the Revel F208 (ranked higher, rated 4.5/5).
Pros: CEA2034 spinorama shows an essentially flat on-axis response with very nice directivity. Predicted in-room response is nearly perfect, with a smooth slope down from bass to treble. Horizontal beamwidth of about ±70 degrees is wide and holds up well until narrowing above 8kHz. Vertical directivity offers more degrees of listening-height freedom than a typical bookshelf design, a benefit of this tower’s driver layout. Distortion is extremely low across the full audio range at 86dB SPL/1m and stays comfortable even at 96dB SPL/1m. Near-field measurements of the individual drivers show nice, well-integrated crossover behavior with only low-level resonances. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 89.3dB.
Cons: Minimum impedance dips to 3.4 ohms with a secondary rise around 2kHz, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).

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.
