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.

@deep_333 - this is exactly where bullies shine. Variable volume, phase, cut frequency AND parametric EQ on top.

I've not heard the Bully speakers, so can't comment on them. I did have Danny upgrade the crossover on a pair of vintage Infinity RS Kappa 7s, and in the end they were expensive.

Part of that cost was my choice, Danny offered me a couple of levels of parts upgrades (from a couple of hundred dollars to a little less than $800), and I chose the most expensive.

To me that was worth it, as the Infinitys were my first audiophile speakers; bought new on release......and they sound amazing for what they are. And the crossovers were beautifully built

The gr research videos are interesting.   Big focus on cost and quality of parts used in various models plus some useful measurements.  
 

Interesting to hear about what you really get for your money in terms of parts used.  
 

I would expect the products and services offered to be high value.  
 

Is that what buyers have found?  Interested to know more.
