#45 REL Acoustics T/9x: $1,499.00 Estimated Amazon eBay
Smaller models: the REL Acoustics T/7x (ranked lower, estimated 3.7/5) and the REL Acoustics T/5x (ranked lower, estimated 3.5/5).
Pros: Flagship of the Serie T/x line pairing a front-firing 10-inch FibreAlloy driver with a down-firing 10-inch passive radiator powered by a 300W Class A/B amplifier. Extends reach down to 27Hz at -6dB with fast musical transient speed.
Cons: Passive radiator configuration requires careful boundary positioning away from corners to avoid room mode excitation. Commands a premium price without onboard DSP or smartphone app calibration.
How it compares: Just above it: Perlisten Audio R12s - $1796 more. Just below it: SVS PC-2000 Pro - $400 cheaper.
