Every GR-Research model 6
- GR-Research LGK 2.0
A small kit speaker from GR Research built around a single 3” wide-band driver, sold as a kit or flat-pack for desktops and near-field listening.
GR Research $290.00 eBay$290per pair - GR-Research NX-Studio
A DIY kit bookshelf with a sealed 6.5” woofer and a semi open baffle Neo3 ribbon tweeter, giving an ultra clean burst decay plot.
GR Research $3630 eBay$3630per pair - GR-Research NX-Bravo
Vertical dispersion is unusually wide for a two-way bookshelf: tonal matching holds from about 50° above the tweeter axis down to 20° below it, well beyond the roughly ±10-20° typical of most two-ways.
GR Research $1540 eBay$1540per pair - GR-Research X-LS Encore
An amazing value for a speaker that measures this well.
GR Research $1300 eBay$1300per pair - GR-Research Klipsch RP-600M Upgrade
GR Research’s replacement crossover fixes the stock Klipsch RP-600M’s biggest flaw, a deep response dip around the crossover, by using gentler first-order filters.
GR Research $279 eBay$279per pair - GR-Research NX-Treme
Amazing in terms of soundstage and imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box.
GR Research $9662 eBay$9662per pair
