Short answer: the JBL HDI-3600. It ranks #28 of 71 floorstanding speakers by sound quality at $3800; the Perlisten R7t ranks #29 and costs $4995, so there is little reason to consider the other one.
What the Perlisten R7t offers: The flagship of Perlisten’s R-series towers, a 4-way design with four 165mm woofers reaching a measured -3dB extension point of 49.1Hz. The Harman in-room extension estimate (lfx) is a deeper 38Hz, since that metric accounts for room gain the anechoic -3dB figure doesn’t. Sensitivity of 90.0dB makes it easy to drive at high output. Watch for: Listening-window smoothness (0.567) and sound-power smoothness (0.380) are middling for a flagship-tier tower, with on-axis deviation of 0.341dB, a fairly pronounced -0.29dB per octave downward tilt, and a predicted in-room smoothness of just 0.44. It’s sold only through specialty AV dealers at a per-unit price.
What the JBL HDI-3600 offers: 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. Watch for: 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.
Buy the JBL HDI-3600. It ranks higher for sound quality than the Perlisten R7t and costs less, so there is no real case for the other one.
