AccuGroove Bass Cabinets - "Audiophile on Steroids"

The folks at AccuGroove like to say that their cabinets are "Unique in concept, flawless in performance".

What makes them unique?

Each cabinet contains multiple speaker drivers, and each speaker is enclosed in it's own specially tuned "cabinet within a cabinet" so the speakers don't interact with each other. Four-way cabinets contain sub-woofer, mid-woofer, mid-range, and tweeters. Professional-grade 14-gage oxygen-free copper wire is used, and the crossover circuit boards are built by hand, with self-resetting protection circuits on tweeter and midrange. The cabinets are made from high grade ¾" and ½" void-free European Liteply, with rabbet and dado construction, recessed handles, vibration-free steel grill, and black Ozite covering (a tough cloth material). The cabs can be stacked and oriented vertically or horizontally.

So, what about audio performance?

The AccuGroove cabinets were the result of a search for a fuller and more sonically complete bass speaker. No more mixing & matching cabinets to get the right sound. It's all right there in one box.

Product Spotlight - February 2007
The International Institute of Bassists has a product spotlight on AccuGroove. The article has great coverage of the origin of the company and it's speaker cabinets.

Listen to what people are saying about AccuGroove:

Sylvain Savaria of Quebec: I just love my El Whappo! What I heared is true - all the frequencies are there. The guys in the band were impressed: though I didn't play as loud as usual, everyone could hear me better! That's really something! Thank you so much Greg!

Marshall Hay of Ontario: My new amp arrived today, so I had a chance to give the Accugroove Tri 112L a test drive. All I can say is wow! The Thunderfunk 550B/Accugroove 112 is a terrific combination, and I am very happy with the cabinet and your service.

Andrew Lusher, Ottawa, Ontario: My Acme B2-II cabs are no longer part of my default stage rig. The main "issues" I was having didn't relate to achieving "my sound" but had a lot more to do with cabinet efficiency and projection. This is what got me thinking about AccuGroove cabinets in the first place. Mark Wright of AccuGroove was wonderful to deal with, and my El Whappo order was in the queue and would soon be on the way! I tried to provide as much lead-time as was possible given that a very important date was looming on the calendar. Mark of Accugroove and Greg Holmes of GH Services (who was also great to deal with), moved heaven and earth to get the El Whappo built, through Customs, and up here on time.
Greg really went the extra mile to pull off a miracle, because on Friday the cabinets were stuck in the Toronto shipment hub with apparently no possibility of delivery to Ottawa until Monday. But my cabinet arrived Saturday morning with enough time for an appropriate break-in period before our sound check. Everything came off without a hitch (we sold out the show, broke attendance records, and have locked in five more dates for the venue). Both of these good folks are due a very big THANK YOU. You all rock!

Kate Schutt, Guelph, Ontario: I have been playing with the 112L cab for almost a month now and it is UNBELIEVABLE! Sound: The clearest sounding bass cab I have ever heard. What I hear is the sound of MY bass ... not something else. Portability: It is the easiest, lightest thing to carry ... again, truly remarkable. I would highly recommend that anyone purchasing the cab get the case/cover that goes with it ... it is nice and padded and keeps the whole thing safe when moving it in and out of clubs.

Paul DeLano, Oregon: El Whappo is simply the best sounding cabinet I have ever played through. Lows, highs, volume, you name it it does it.

Skip Fantry, Knuckle Guitar Works: El Whappo has the most natural tonal breadth of any single cab I have ever experienced.

Bill "The Buddha" Dickens: This is the sound I’ve been looking for years but have never been able to find until now. After using these cabinets, I'm more excited about playing music than I’ve been in a long time. I couldn’t even blow them up. AccuGroove cabinets are DEVASTATING!

Larry Kimpel: Oh my God! I played my first gig with my band last night with the El Whappo and...Oh my God! The warmth, the fullness, the projection at low volumes, every frequency that my basses put out was honestly and accurately reproduced all night long! Oh my God! I'm in love with my El Whappo!

Gregory Bruce Campbell: Other cabinets have a tendency to drive your sound for you, and you are only the passenger...Wouldn't you like to drive for a while?

Myron Dove: Ok man...it’s time for a report...THOSE %@*#$ CABINETS ROCKED ME SO %@*#$ HARD I COULDNT BELIEVE IT WAS REAL.THEY ARE LOUD, CLEAR AND FULL OF BOTTOM. Sweet and full like a mango...You and Dave are truly da man...Well done on a very fine job. I finally got a cabinet I can call home. :-)

Dann Glenn: My AccuGroove El Whappo is the missing link in my quest for the ultimate bass sound. These cabinets give a flawlessly accurate reproduction of what's coming off my hands, not out of the amp. This is what all bass players dream of.

Paul "Polo" Jones: "I've never played through anything like these before. After using everything out there, I can easily say that these are the BEST boxes you can get...period!"

Designed for musicians that want the acclaimed El Whappo sound, but in a more compact package. When matched with the Tri112L, it's like a portable alternative to El Whappo. It's also an excellent full-range cab, with a big, warm sound.
All cabs from here on down are stackable, since they have the same footprint.

It goes lower than most 4x10 cabs while having more mid presence and a more developed high end. Two of these cabinets together are ridiculous.

This is not your normal 2x12. The sub-woofer and mid-woofer drivers in this cabinet are both 12" but are completely different, optimized for their specific roles. Each driver is in its own separate "Cabinet within a Cabinet", of course, so they do not interfere with one another sonically.

This is the cabinet that started it all! Lighter than most 4x10 cabinets on the market, it can easily replace 2 of them. It's like a giant studio monitor that will produce the entire sonic spectrum of your bass, whether it's a 4 string or a 9 string. Clarity has a new meaning, from the huge tight bottom end, through the crisp warm mids, to the sweetest highs you've ever heard. An amazingly huge clear sound without coloration.
