Last week we received a visit from Jules Meuffels from JM Speakers – Boutique Bass / Guitar Cabinets. We have extensively tested his hand-built cabinet ” The Trunk ” and can safely say that it is the ultimate 1×12” cabinet.

1×12″ That sounds like nothing that you tried before! Evolution in guitar and bass cabinets!

Just had the honor of testing the new 1×12 cab from Jules Meuffels …

Of course I have a trained ear and I know exactly what I want to hear … does not take away the fact that I was immediately very impressed by both the pressure, the dispersion and the low that this cabinet produces!

This is a speaker cabinet that comes into its own when you just put it on the floor. Space is immediately pleasantly filled with a full and warm sound. Both clean, crunsh and lead remain nicely open but also tight in the lows. Balance bass / treble is good and the speaker (vintage 30) speaks very directly …

Absolutely recommended according to unique recipe; and the appearance can also be carried out according your own unique wishes. Nothing seems to be to crazy for Jules: “showroom shine” or relic; the (real) leather is executed in the desired color and desired state …

In short: recommended!

Yesterday afternoon had the honor of testing the prototype of Jules Meuffels’ latest creation: The Trunk! The Trunk is a speaker cabinet for guitarplayers, with in this case a 12 inch Celestion V30 speaker, 8 Ohm. The speaker is screwed on a rearward tilted speaker baffle. As a result, you do not have to tilt the cabinet to hear yourself. The trunk is loud! According to earwitnesses audible a few blocks away haha. And it definitely doesn’t give you the feeling that you are playing on a cabinet with only 1 driver. The sound is full, very tight in the lows, very nice and clear mids and dito highs. The cab sounds wonderfully punchy and has an incredible dispersion. Whether you’re standing right in front of the cab or next to it: the sound stays super audible. This is the result of the ingeniously thought-out chamber system behind the speaker panel and a bass port across the whole front of the cab.
Also not unimportant: the cabinet is lightweight! And due to the position of the handle, the cabinet will be easy to transport.
You really must hear this cabinet yourself! I’m sure you’ll be very happy, like me!
It was a fun afternoon Jules! Thanks for your hospitality. Very nice that Roeland was there. Join three musicians and time flies!

For the Guitarists and Gearfreaks among us: Jules has designed the perfect speaker cabinet! Nice lightweight, good punch in the mid-lows (something that is missing in many cabinets) and more dispersion than an average 4×12 cab! I would say; Try it, before it becomes a hit!! This is a real asset!!

I just tested the prototype guitar cabinet Jules Meuffels (JM) made. I already knew JM builds high-end cabs for bassists. Now Jules makes cabinets for guitarplayers! I was truly amazed bij the volume, depth en punch of his new cab. I compared the JM cab with a stock F….. (well known brand ) cab. Both have a 12″ Celestion Vintage 30 speaker, but what a huge different in sound (and aesthetics)!! Compared with the stock cabs the JM cabs sounds lively, roomy and most of all, has that typical “oempf”, guitarist search for, without losing any high tones.
De craftmanship of this cab is very, very nice. The slightly slanted speaker enables you to set the cab on the ground and still hear it if you stand close to it during a gig. Another thing I really liked was the closed back, and bassresponse on the lower front of the cab. In a live-environment this comes in very handy. Whether you play in clubs or on a larger stage, the JM always sounds good! On a sidenote, these cabs can be finished in a number of boutique looks, like the worn-leather-look. I am very looking forward to your new line of guitar cabs Jules!
I think every guitarist should own a JM cab or at least try one out. I am sure you will not regret it!
Keep up the good work Jules! And my best regards to Kelly and Oscar!

Today I tried the prototype of the new guitar cabinet build by Jules Meuffels and it sounded superb! He uses the same driver as in my own, only this cabinet is wider, the speaker is placed at a slight angle and there’s a port so the lows can escape at the front!
It sounded better than my own cabinet, much more spacious in the lower frequencies without getting too much! No exaggerated sub.
Jules is on the right track to make a killer cab!
And again, same speaker, but completely different cabinet, and a clear difference!

Translation German article:

Tall / Open
JM Speakers Triton,
Jules Meuffels wants to present us the ultimate bass cabinet, it certainly looks unconventional. Where the Bassplayer and Industrial Designer sets his priorities will be demonstrated by this navel-high construction. The upright format of the narrow box automatically move the speakers closer to your ears, a positive contribution resulting in good audibility of your playing. What is striking second is the tremendously high loading capacity, 800 Watt or double for short-time peaks.

Even if the first impression is a horn construction (rare) the solid cab – made of 15,5mm poplar plywood – is built according to the bass reflex principle. The chosen material is relatively soft and light, what positively influences properties in terms of resonance damping and weight; it weighs 21 kilograms, yes indeed not particularly heavy. Especially, this high-end design is convincingly robust, the inside is stiffened by two perforated braces all around. A contribution for the suppression of cab resonance is a Felt cover, and a tapping test actually unveiled a “dead” housing. The interior is three-quarters covered with nubbed foam (eggfoam), that swallows standing waves and ensures that no boxy sounds escape from the large port on the front.
The remarkably high load-indication is not a gross exaggeration, because the Beyma twelve-inch 12LX60-V2 is also included in the manufacturer’s data sheet where 700Watt is listed. Whether it in reality has 100 watts more, doesn’t really matter, this high-performance speaker with gigantic ceramic magnet overrules any competition. The combined Beyma five-inch 5G40-ND has its own chamber, and is itself a highly potent low – mid – range driver, whose pole plates are eight strong neodymium magnets. It can get down to 90Hz and at the same time has enough to play back up to 17kHz.
When investigating the Triton the clean and precise craftmanship stands out. Why the 5” has a chamber of its own, but the cable duct was not sealed from the bass chamber, was puzzling. No harm in a splash of silicone at this point.
Jules Meuffels selected a light and open metal grill, a neccesary protection for stage conditions. To avoid rattling at high levels, it is mounted on eight rubber blocks, two more rubbers are pressed from the inside out, in the area of the bass port. All cabinet corners are covered with tough ABS plastic caps. Protection rubber feet on the bottom to ensure a slip resistant stand. Why the JM cab only has one handle puzzles me, but in fact you can move the 21kg’s around with one hand because of the balanced position of the handle. But two would certainly be more comfortable.
As specific as this bass column looks, as remarkable are the lows. Conventional ported cabinets usually show a condensation of port lows to give the instrument a fat pressureful base. Also, in the normal two-way designs, high-frequency horns are often used, which give you sharp clicky highs. The JM Triton lacks both the enhancement in the lows as well as the metallic highs – on the other hand, it presents the bass notes in almost obvious naturalness and transparency, from the deepest subbass to delicate highs. The characterizing mid region is represented with unusual directness and proximity, the midbass nuances also come without noticeable discoloration and therefore portray vividly what really comes out of the instrument played. One can really be amazed how dynamic, clear and elegant this two-way cabinet sets all frequency ranges into the scene, and that with healthy efficiency and cleanliness up to high levels –
Jules Meuffels does not promise too much, when he promises to offer the ultimate in bass reproduction!

This bass cabinet is very special, starting with the striking upright format, over to the used High performance speakers, up to to the courageous furnishing with only one (balanced) carrying handle. Most specific, however, is the impressive natural sound displacement that is transparent and clean in all areas from the deep Subbass up to filigreed heights with fresh dynamics. The Triton is thus a reference Loudspeaker for the natural reproduction of the instrument sound and has at the same time the resilience reserves, in order to bring extreme sounds even more appropriately. The boutique label is perfectly matched by this exceptional bass cabinet.
And at the end, even the price is still quite reasonably well founded.

Today Jules Meuffels came to show his hand built line of JM bass cabinets, at the Muzikantine in Horst.

Many different configurations were tried; Ampeg transistor, Ampeg tube with Ampeg 4×10″ cabinet, Markbass 2×10″ combo plus 4×10″cabinet, TecAmp 1×12″ combo, TC electronic 1×12″combo, compared with different types of bass guitars, from passive to active. Even an upright with a Slap pick-up!

In addition, the JM stood his ground. These cabinets with 1×12″ woofer and  1×5″ cone tweeter are perfectly balanced because of, for the layman incomprehensible mathematics and physics calculations. Connected to any head, JM was unanimously voted winner this afternoon.

Fantastic stuff, affordable, beautiful and practical.

What more can you ask for ….

The perfect bass cabinet? I’ve found it. The JM Triton. Fat tight lows, crisp highs and the mid/midhigh is perfectly balanced by the use of a 5 inch speaker instead of a tweeter. That makes it sound deliciously transparent.

And when the deep switch on my Mesa Subway D800 was turned on, there was an impressive amount of sublow from the Triton. Hard to believe that a 1 x 12 inch cab can produce so much low.
In short: WOW! I want them!

Today I finally had the opportunity to check out the JM Triton. I was very curious about this cab for a while, and now I found the time to give it a try! I compared the JM to my trusted Bergantino HT112. This is my small travel cab and I use it for smaller gigs.

As most bass players know, a single 12” cab is cool but sometimes sounds a bit thin or a second one is needed to “survive” loud guitars and drums. My experience with the Berg is good, this cab does stand up to loud settings! Another issue of single 12” cabs is that most of them are missing BOTTOM.

There is a new player in the High End bass enclosure market. I believe the most important ingredient for designing a descent Bass enclosure is having a LOT of experience in playing da Bass in live settings and rehearsals. Not just theoretical designing on the drawing board or testing in studio’s or living rooms and so on…..  Theoretical values are not interesting to me, the actual performance is the thing that counts! Jules is such a guy. The desire to build a cab that can handle it all.

After our rehearsal, I met with Jules in the rehearsal facility. He brought in his baby, the JM Triton. First impression, the cab looks awesome!!

The test set-up:

Sadowsky NYC Standard 5 String (Alder/maple)
Aguilar DB 751
Bergantino HT112 as reference and the JM Triton

A no frills test set-up. No effects etcetera….

After playing a few notes on the Berg it was time to switch to the JM Triton.
My first impression soundwise: This thing goes DEEP!!!! WOW!!! It projects everything you put in, as much as possible. Of course, the Aguilar isn’t the straightest amp but TMHO the Bergantino is pretty neutral. The JM does the trick as well but with more, tighter bottom-end than most 15” Cabs. The JM  is the virtual marriage of a 10” and a very good 15” with a bit 18” low end! Whatever you do, do NOT touch the bass pot on your amp! Why? You don’t need to. Another great feature is that Jules didn’t use a conventional bullet tweeter. He explained to me the reason why; On a larger stage you don’t hear a tweeter as soon as you step aside of the cab. Instead, Jules uses a Ceramic 5” cone driver, which spreads the highs nicely. So overall this cab delivers a full range sound with a unique dispersion. VERY IMPRESSIVE!!!!

Of course the cab is much taller than (in this case) the Bergantino. That is one of the reasons it produces so much bottom. The pro on this is, most bass players can put it on the floor, and yet the footprint is still smaller than most 12” Cabs. With 21 kg’s, it is easy to transport. For most bass players this could be THE 1 cab solution.

I‘m very curious about combining more Tritons, unfortunately at this moment Jules had only 1 test cab available. I’m confident combining 4 Tritons will deliver a wall of sound which can definitely handle ANY gig.

If you ever have the chance to check one of these out, first check your bank account and then go for it!
They won’t disappoint you!
