Brand: GR-Research
#53 GR-Research X-LS Encore: $1300 Gr-research
Pros: An amazing value, especially if you managed to snag one of these built by AV123 in the early 2000s for $200-300. 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.
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. As a DIY kit, it requires building the cabinet and crossover yourself.
How it compares: Just above it: JBL Studio 630 - $601 cheaper, 1.2Hz lower bass extension (-3dB). Just below it: Infinity IL10 - $1140 cheaper, 1.6Hz higher bass extension (-3dB).
