A brief review of GR Research Bully


I was looking for speakers that would allow me to enjoy classic rock at reasonable volume. NOT at a venue volume. I don’t like loud music at all. Thus something that allows me to have full spectrum sound without having to crank in up. First I tried ProAc 38R, which were nice, but lacked bass at low volumes. Accuphase amp has loudness and tone controls, but they did not quite worked to my satisfaction.

So I ordered a pair of GR Research Bully, assembled. GR typically sells kits, but I am not into finishing cabinets so rather prefer it professionally done. It took about 12 weeks from the order to delivery. I did not buy matching stands and instead ordered custom metal made for me.

I am very satisfied. The bass section is powered - the amp is Rhythmik. It is, effectively, a subwoofer and is very adjustable - crossover frequency 40-120Hz, phase 0-180 and even includes parametric equalizer. This allowed me to adjust amount of bass to the volume level I prefer.

The speakers come with printed measurement chart (in GR Research room). I also performed a number of measurements in my room with UMIK-1 and REW for Windows. I could make frequency response pretty close to linear, but prefer a bump below 100 Hz to compensate for lower listening volumes. Waterfall is also very clean, no ringing.

Associated gear: Denafrips Terminator with DDC, Rega P6 + SoundSmith MC, Pass XP-12, Accuphase E650. The room is 30x16x8 with some acoustic panels and ASC Tube traps.

Thanks for the post. I looked at these in the past and thought they were interesting.

How about a little insight into how they sound?

@ozzy62 This is very subjective, my material may not be very "audiophile" :-). I would say, sound is clean and transparent. GR spends quite a bit of time on time alignment and off-axis response. The latter is actually very good. As compared to ProAc bullies sound really good even 20 degrees off axis, no need to be exactly in a sweet spot. In overall sound is typical for the type of units they employ - looks like a silk dome tweeter and plastic (?) cone mids. I personally prefer sound or planar tweeters, but I cannot say that Bully is ’forward’ sounding. As compared to my Meze Elite headphones some transparency is obviously lost and bass clarity and definition is not the same. But then again, we are talking room response vs top shelf cans.

It is probably possible to achieve similar results with stand mount speakers and two subs, but it probably will be more expensive for the same sound. What attracted me to GR is attention to engineering details rather than marketing and speaker appearance. I would say these days $5K is a bargain for the sound Bullies provide.

look that guy, spent an entire eposide reviewing some speakers without the bass drivers and pointed out the lack of bass the whole time, frequency response curves and all. hey why not listen to them WITH the bass driver(s) connected? maybe theyll measure beatter, einstein.

over the ohone he acknolwedged that the bass briver was missing and also claimed he doesnt review speakers, and last i checked the review os the megneppan minis are stll up. (cant remember if external links are alowed here, so read Flat Panel "Mini" Magnepan Audiophile Speakers!).


he has hisn moments,  but hes also unapologetically full of it.
