Pro Sound Web had their subwoofer shootout on January 29th and 30th in
New York City
. The JTR Growler was the only small format subwoofer and was the under dog in this shootout where only the top SIX make it to the second day for a full listening evaluation. Its small size quickly became the topic of conversation as it sat there among the biggest and baddest subwoofers. When the time came to test, many observed the GoldLine TEF analyzer and measurements showed a smooth flat response to 40hz and low THD, which peaked everyone’s interest further. During the short listening session, everyone gathered as the little Growler put out some big sound. At the end of the day, after all the subs were put through their test, the votes were tallied and the Growler advanced to the second day!
The second day was dedicated to listening to several different music tracks though each subwoofer. Many of the speakers did not leave unscathed as three out of the five subwoofers prior to the Growlers had fallen victim to the PowerSoft K10 amplifier’s 10,000 watts. One channel of the amplifier when hooked up to each of the two Growlers is capable of 4000 watts. The Growlers sounded great, overcoming technical and challenging tracks. With two tracks remaining, the decision was made to put REAL power into the Growlers and the faders where laid into. The Powersoft K10 CLIP lights were flickering, concern was in the air, and the Growlers ROCKED!!! Putting out peaks of 129DB at 16 feet away, the JTR Growler showed it could perform. Big thanks to Paul Bell for organizing this event!!

Comments made about the JTR Growler:
Elliot Thompson-
JTR Growler
This is a small company that you really need to keep your eye on. The Growler houses one 12-inch woofer in a folded horn. The box is so small (30"x 20"x 22.5") you can throw two in a car.
Listening Test
This box actually blew a lot of people away. Normally, when you see a small folded horn the first thing comes to mind is a 10-dB drop @ 60 Hertz. However, this box worked it's way in the mid 40's without the irritating,
ear fatiguing, peaky response, that many horns of that size are known for. At some levels it did clip the Powersoft K 10. However, it was momentary, and not long-term. The Quality is very High Fidelity and, you do wonder if it's indeed a horn playing. If I were looking for a little sub, this would be my first choice. It's flexible enough to stack 2 wide 6 high with a pair of JTR Tops (Still under works) sitting above to achieve a substantial
amount of output.
Jeff Knorr Cobra Sound-
The JTR box was definitely the sleeper of the pack and provided some serious
low-end from a small and affordable package.
Scott Hibbard-
JTR Growler
- Extremely punchy and an amazing speaker - esp. when you consider it's size
- VERY compact subwoofer. You could probably fit 4 of them in the back of a SMALL SUV with room to spare. If I recall correctly, two of these were smaller than one Quake by a decent margin.
- HPF 30Hz, LPF 80Hz
- Smooth response down to 40Hz and then fell off from there.
- Coupled very nicely
- Saw peaks around 128db (16ft away) at 65Hz with nice impact
- Speaker seemed happiest between 45Hz and 75Hz
Tim McCulloch-
All the boxes that made the final cut for tomorrow's listening evals were good in their own right, but for me, the Growlers were the "sleeper" of the bunch. I think Jeff's little sub surprised everyone, and we're looking forward to hearing more from it.
Mike Butler-
The feisty little Growlers were more fun than 64 ounces of beer (which is the other kind of "growler" as those of us who have visited the microbreweries of Vermont all know), What a pleasant surprise.
