#107 GR-Research X-LS Encore: $1300 per pair GR Research eBay

Pros: An amazing value for a speaker that measures this well. It is sold as a finished speaker, and anyone willing to build the cabinets and crossover can save a lot with the X-LS Encore kit. CEA2034 spinorama shows a generally flat on-axis response, especially in the listening window. Predicted in-room response is generally smooth and on-target. Distortion at 86dB SPL/1m is pretty clean above 200Hz. Measured bass extension of 64Hz (-3dB), with a measured sensitivity of 84.4dB.

Cons: A slight depression in the upper bass and some peaking in the lower bass shows up on-axis, along with directivity error in the crossover region. Vertical directivity requires staying within about 20 degrees of the tweeter axis. At 96dB SPL/1m distortion becomes “rather unhappy,” with bass distortion, a possible woofer issue around 2kHz, and a tweeter problem above 7kHz. The finished pair is built to order with a lead time of 3 to 5 weeks.
