Short answer: the Emotiva Airmotiv T2+ on value, the JBL HDI-3600 on an easier load. The T2+ is a high-value three-way tower with strong output and unusually deep usable sealed-room bass, and it costs $999 against the JBL’s $3,800, but its nominal 4-ohm system approaches 3 ohms near 100Hz and wants a high-current amplifier. The HDI-3600 stays flat and efficient at 90dB with very low midrange distortion.
Buy the JBL HDI-3600. It is rated higher for sound quality, and the Emotiva Airmotiv T2+ is discontinued, so it is only available used.

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.

Emotiva Airmotiv T2+: $999 per pair Discontinued Emotiva eBay
Newer model: the Emotiva Airmotiv XT2. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: High-value three-way tower with strong output and unusually deep usable sealed-room bass for the price. Erin measured F3 at 62Hz and F10 at 32Hz, with sensitivity just under 90dB/2.83V/1m. Dual 8-inch woven-fiber woofers relieve the 5.25-inch midrange, and the 32mm folded-ribbon tweeter provides broad horizontal coverage. Approximately +/-2.5dB response linearity, solid cabinet bracing and low compression allow substantial playback levels; the gradual low-frequency roll-off integrates well with either room gain or a subwoofer. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: The nominal 4-ohm system approaches 3 ohms near 100Hz in Erin’s measurement, so a high-current amplifier is preferable. Horizontal and especially vertical directivity through the midrange/tweeter transition is less uniform than the best waveguided or coaxial designs; listener height and nearby reflections matter, and EQ cannot correct the narrowing mismatch. The large rear-ported cabinet needs placement clearance, and its deep F10 should not be confused with flat 30Hz output at cinema levels. Discontinued.
