“Kammler Speaker Cabinets are truly the most versatile and transparent I have ever had the pleasure to play through. From the cleanest acoustic harp guitar resonances, to the most overdriven, savage electric guitar tones, these impeccably designed cabinets deliver the whole sonic spectrum in pristine, audiophile quality!”

“The ‘Kammler’ guitar cabinet delivers a very full and powerful sound, which always remains differentiated and transparent. Almost impressive is the ability to fine-tune the sound by changing the tension of the cabinet through the patented ‘Tunator’, giving the sound something you need: Fuller, wärmer or more detailed and transparent. The Cabinet looks very solid and sturdy and will withstand even harder jobs.

I can only recommend to anyone to test this guitar cabinet and convince themselves of the impressive sound. “

„To all my guitar player friends – here is a pretty revolutionary product that’s worth checking out. Imagine a high-end cabinet that is tunable in its resonance (yes through metal rods applying pressure inside!) and has an omni-directional sound pattern. This is achieved through structures inside the cabinet and a super wide open back opening. When I played the cabinet some of my favorite tones were coming from the back of the cabinet!“

Scott Walker

Luthier, Guitarist and Steel Guitarist

“The Mono-Kai really is a cabinet like no other. I immediately realized, up until now, i have been “correcting” my cabinets EQ with my amplifier. This battle is over with the Mono-Kai, now I can really hear my Amp, which means now i can really here my guitar.“

Adam Miller

“A huge soundstage – and yet a very focused tone with a massive bottom end extension!”

“These cabs are killer. Smooth `n bright treble, nice mids, a tight bass response and a 3D-sound-out of this world! That‘s the real shit.
Give it a try …”

“Your cabinets are just brilliant!!! They sound awesome both with a clean sound and a dirty sound with really cool designs going on … WOW!”


Stefan Bernheimer

“I’m playing a Mono-Kai II (Celestion AlNico Cream) and a Mini-Kai (Jensen Blackbird) and I love the sound. It’s so much better on stage, the sound is very very natural and beautifully defined. From clean tones to high gain: It’s a pure pleasure! I don’t want to miss these 2 ‘Kammler’ Cabinets anymore.”

“When I first read about the ‘Kammler’ Cabinets, I was very skeptical: reinventing the cabinet? I thought it was a marketing gag until ….yes, until the day I played a gig over a borrowed Mono-Kai: My amp sounded better than ever, I could hear myself everywhere and equally well. The sound spread wonderfully in the room and the guitar was perfectly located within the band structure. The compact 112 sounded as big as my earlier 412 cabinet, but much more detailed and with an incredible attack. “

“I have never heard cabinets (112 or 210) which are so handy and sounds so huge”

“If you want your FOH to give you flowers and go out for dinner with you, then put him on the stage with a ‘Kammler Cabinet’. It’s very clear in definition, speaks incredibly fast to the signal you’re playing. Since I played ‘Kammler Cabinets’ I don’t need to rip my amp like that anymore, but I still got stuck in the band structure, but lately I’m still quieter.”

“Kammler Cabinets give me the right pressure and tone I want. They are the best I’ve ever heard.  Just great cabinets and a great guy who builds them with dedication.”


Markus Born

“With the ‘Mini-Kai’ (110), I finally found the optimal recording cabinet. The EQ has become redundant. The ‘Mini-Kai’ delivers the perfect and impressive ratio of tonal envelope and sustain with absolutely natural sound of the characteristics of each guitar. The cabinet is always clear, punchy and dynamic. Handling of he microphone is extremely simple, since the cabinet has a very uniform radiation behavior. Ideal also for club gigs, as it never gets shrill on the main axis and off-axis and presents almost the full tonal spectrum. This allows me to control precisely the sustain and feedback behavior of my Gretsch 6120. Control the space – play ‘Mini-Kai’!”

“Both live and during studio recordings my 1×12″ Kammler Tunator® Cabinet sounds extremely transparent, warm and space filling – without cutting or dull interference frequencies with which our guitarist guild has frequently faced with. The cabinet seems to me like an acoustic magnifying glass that can mercilessly depict all weaknesses and strengths of amps and other gear. You hear, that here is not simply bolted a membrane into a housing: Here an intense audiophile research has taken place.”


Oliver Keller (Schweiz)

“The cabinets made by Dietmar can not be surpassed in terms of clarity and balance.
Live, but especially in the studio, you can see, hear and feel drastic differences from conventional guitar cabinets.”

Michael Palm

“Dietmar Kammler seems to be the first one who understands, defines and manufactures guitar cabinets as musical instruments. The result of his innovation is a tone that has never been heard before. A deeply impressing sound with an outstanding presence and intensity for all styles of music.”

“The Kammlers have ruined every other cab for me. They are simply the best.”

Jens Koehler

“The holy grail of the guitar cabintes! The search is over!
For me by far the best guitar cabinets you can buy for money. In my studio I have been using different models of the ‘Kammler Cabinets’ with different speakers for months and have tested them extensively.
You hear the sounds so clean, directly, tautly, clean and transparent, as I’ve never experienced before. The sound is extremely spatial, no matter where you are on stage or studio. These speakers seem to resonate somehow like a very good acoustic guitar.
Pure dynamics and sustain. This are great cabinets which seem to be more an independent instrument than just a normal ‘box’!”


Till Hoheneder

Comedian, Musiker (Altobellis), Autor

“I was definitely impressed by the sound of your speakers/cabinets. Especially the 2×10 in your ‘Rusty Look’ was a ‘Killer’!”

Max Barth

“I can hardly believe how little I have heard before. The first time, I just had the feeling of having my own sound directly on my fingers. The ‘Kammler Cabinet’ in combination with my ‘REALTONE’ head is merciless – you hear everything, everywhere! In addition to that, good sound recordings were so uncomplicated that I no longer want to miss the ‘Tunator’ construction retrospectively. You just do not need more than that.”

“Despite the small dimension the ‘Mono-Kai’ produces a larger, more sophisticated and lively sound than any other cabinets I know. An ‘all-round noble cabinet’ which  is capable of depicting a good amp and a good instrument in a characteristic way.”


Walter Stapf


“The Kammler 1×12 ‘Mono-Kai’ sounds very transparent, warm and space-filling for a box of this size, which would otherwise be expected only from a 212 or 412 cabinet. These cabinets improve the sound considerably.”


Jan Schwarte

Gitarre – Jan Schwarte Bluesband

“I am really impressed! The sound of the ‘Kammler Cabinets’ is very differentiated, distinctive and precise and finally unique no matter of playing soft or loud, rocky or bluesy! The ‘Kammler Cabinets’ are played by me in combination with the 33 Watt ‘Realtone Amps’ “


Armin Heinrich

“Yesterday I created the first profiles with your 112 ‘Mono-Kai’. I have to say – it’s like a sledgehammer – I am thrilled!
I like the combination of case / construction and the Celestion Gold extremely well. Thank you for the excellent work!”


Rüdiger Konetschny

Echopark Studio

“In our productions we have been using the best speaker chassis in the world for years. Many experiments and tests with enclosures had already brought us to a very high standard. However, when we had our favorite speakers built into nine individually tuned ‘Kammler Cabinets’, the sound of our guitar production reached a new dimension completely unknown to us: the cabinet and speakers merge into a sovereign tonal unity. The directness and clarity of the ‘Kammler Cabinets’ grant us an unsuspected precision in the reproduction of guitar and amplifier.”


Armin Hero

Musiker, Gitarrist & Moderator, Berlin

“Even the first impression of this compact, handy cabinet is impressive! One can hardly believe that only one speaker provides so much spatial presence and you actually think to play a much bigger cabine than a 112 For me, the cabinets by Dietmar Kammler are the reference and the ultimate speaker/cabinet concept. The result is an incredibly clear, transparent and spatial sound, I have not heard it in my 35 music years with a 1×12 cabinet so far.”


Ron Heiringhoff

Gitarre – Seven Boots

“The sound in the room is incredibly good, vivid and extremely three-dimensional. The tonal development is phenomenal and makes customary compensation measures (beam blocker, Deeflexx or equalizer post-processing) superfluous. You are right on the sound and perceive every nuance. The ‘Bi-Kini’ (210) and the ‘Mono-Kai’ (112)  complement my REALTONE top incredibly well. The 210 is extremely likable to me with the clear attack and ‘glittering ‘in the heights, the 112 creates a warm, full founded tone, carries the sound and sings. I can hear myself so wonderful, can play quieter and it sounds like playing with 2 amps. The bass is huge for open cabs, but remain surprisingly crisp and ‘fast’ due to the ‘Tunator’ construction. Endless pure tone. The ‘Kammler Tunator Cabinet’ simply brings the best results, without disturbing frequencies and resonances.”


Micha Tunk

“These cabinets are world class! Extremely  dynamic and incredibly fast in unfolding the sound “

“Kammler Cabinets leave nothing to be desired and offer the an open and dynamic sound I’ve always imagined.  Its a perfect combination between the cabinets and my Realtone amps, which gives me the power to play a sincere and rich sound. Every guitar sounds like it must sound, no matter if it’s a Les Paul, ES, Tele or a Strat.
Nothing comes close to the performance of these cabinets!”


Marco Winkler

Gitarre – Nihiling

“The ‘Kammler Tunator Cabinets’ are a sonic revelation!. I don’t know anything that even comes close to this dynamic and presence.”
