Super12 combo and Super12 cabinet.


The combo weighs only 14 kgs and is only 40 cms high. The built-in amp delivers a high end 400 Watts/4 Ohms. The 12″ bass-mid loudspeaker offers a beautiful sound, both for bass guitar and double bass. The slot tweeter gives that restraint filigran high up to 20 kHz, important for overtones and audability on stage.

The Super12 cabinet has the same 12″ bass-mid loudspeaker, which can be loaded with 500 Watts AES. This cabinet weighs 11 kgs. The total set (combo and cabinet) is only 80 cms high and can be loaded with 1000 Watts. Instead of the Super12 cabinet it is also possible to combine the combo with the Super15 cabinet, when more accent is needed in the low registers. Price Super12 combo € 1650,- incl. tax, Super12 loudspeaker cabinet € 820,- incl. tax, off Panningen (Netherlands). Hevos ships worldwide.

Both connoisseurs and bass magazines consider Hevos playing in the premier league of bass amplification. Read more info and reviews about the combo and cabinets at this website.


2×6 combo and cabinet
















Hevos smallest combo and cabinet. Built-in high end 400W amplifier. Dimensions hxwxd : 44x23x32 cm. Weight: 10.3 kgs (combo), 8.7 kgs (extra cabinet).

Is it possible to reproduce a wonderful and mature bass sound with 6″ loudspeakers? Despite the very small 6” loudspeakers it offers an astonishing bass reproduction. The sound is great, it is unbelievable that these Hevos 6” loudspeakers can reproduce bass sound so well.

Gitarre&Bass review: “It is simply amazing what a full detailed and rich bass sound Hevos gets out of these small 6 inch loudspeakers. But if one takes a closer look at the powerful special loudspeakers and the very solid construction of the housing, it becomes clear that it’s not magic but rather robust physics that leads to such results. All the more since the high-quality 400C combo amplifier has lots of power available.”

New: Thor15 loudspeaker cabinet

The new Thor15 loudspeaker cabinet is a spin off of the recently introduced  Thor15 bass combo.

Technical data:

Cabinet type: bass reflex
Loudspeakers: 1 × 15 “, slottweeter
Power handling: 500 Watts AES
Filter: 2500 Hz
Frequency range: 35 Hz-20 kHz
Impedance: 8 Ohms
Sensitivity: 100 dB /W/m
Connectors: 2x Speakon
Dimensions hxwxd: 54x46x35 cms
Weight: 14.3 kgs

The Thor15 is powered by a 15 “bass-mid loudspeaker that is not only good in the low registers but has also a beautiful  mid response. This combination of a good low and mid response is often a weak point in today’s 15” bass cabinets. The applied 15 “loudspeaker combines a low cone weight with a high stiffness, resulting in an extended frequency range. Because of this and the powerful magnet heavy loads are no problem: the sound remains tight. The dynamic slottweeter produces a silky soft high up to 20 kHz.

The combination of this special 15”loudspeaker and the slottweeter ensures the sound remaining transparent, a well known feature of all Hevos cabinets and combos. Therefore, the audibility both on stage and in the rehearsal room is always good. The slottweeter can be controlled by means of an L-Pad at the back of the cabinet.

The Thor15 combo has a continuous power handling of 500 watts AES, weighs 14.3 kgs and its height is only a knee-high 54cms. This combination of powerful reproduction, low weight and small size makes the Thor15 an attractive ‘stand alone’ bass cabinet. But if one wants to combine the Thor15: it has the same surface dimensions as the Super12 or Super15 loudspeaker cabinet, making it a stackable combination.

The Thor15 cabinet is just the way HEVOS cabinets are meant: the ‘sound’ is made by the instrument and of course by the fingers of the bass player. The cabinet just reproduces that sound.
