The Devastator MkII Horn is available as a high-efficiency, low-tuned (19Hz) ported horn cab for home theater and music-tuned (28Hz) edition for maximum output in high SPL music applications.
The 19Hz home theater version has a low-tuning on the bottom end for great home theater AND a very high efficiency in the upper bass for actual kick-in-the-chest mid-bass performance.
The 28Hz music edition has a higher tuning which provides 5-6dB of additional output around the tuning frequency, but with less extension. Its massive 6" tall lower port is designed to minimize compression; as a result, this monster is capable of 130dB of output at 30Hz and upwards of 140dB in the upper bass.
Most subwoofers that reach for the bottom end for home theater have very low upper bass efficiency. So while they may 'get loud', they don't have the visceral impact that high efficiency subs can provide. By way of comparison, a UM18 driver has an efficiency in the upper bass of about 0.5% (one half of one percent), while the Devastator has an efficiency in the upper bass of 25%, which is 50 times greater!
Originally designed as a high-output outdoor subwoofer, it turned out that with a port re-design it could work very well as a full range home-theater sub. The design places a horn-like path in front of a 21" driver, which creates the absolutely massive increase in mid-bass efficiency mentioned above. The result is super-clean bass that has an immediacy and impact that is difficult to describe. It is the kind of sub that when the mid-bass hits, it can be startling and/or make you jump in response.
We recognize that this sub is huge and won't work for most folks. However, for those who have the space and want something very special, we are pleased to bring you...The Devastator!
The Devastator MkII has a larger port to accommodate the extreme excursion of the Eminence Tour Grade Driver; while still performing optimally for the LaVoce 21".
The Devastator MkII is now available in MDF or Baltic Birch! The material makes no difference in sound quality or output level. The music version is only available in Baltic Birch for greater durability and safety on the road and in other pro-audio applications.

One of our customers, Jiles of the YouTube Channel JDM World, created an amazing step-by-step video of his build experience. Thanks Jiles!! Fantastic work!!
The Devastator MkII has a slightly different port layout but generally the video provides a good sense for the Devastator build experience.
Fully Finished Powered Devastators Now Available!
For those who want to experience the power of the Devastator, but who may not have the time or the inclination to DIY, we have great news - fully finished, powered Devastators are now available! And to simplify the purchase experience on finished subs, all finished subs include FREE SHIPPING!
We have combined the most powerful cabinet on the market with the most powerful plate amplifier that we are aware of - the legendary SpeakerPower SP1-4000HT.
For those who may not be aware, SpeakerPower develops "tour grade" amplifiers for duty in the most punishing conditions, such as live EDM shows. Given this, it was a natural fit to power the Devastator.
For folks who would like to run finished Devastators off an amp they already own, we've got you covered too with the 'passive' finished Devastator option!
We have also included custom tuning unique to the Devastator in the SpeakerPower plate amp.
Devastator Custom Tuning with "LF Adjust" - The plate amp includes an "LF Adjust" knob, which will allow you to dial-in the right amount of low-end for your listening conditions.
If you are in a huge home theater or room (where you will have little or no room gain, turn the dial all the right and you get the full low-end boost (black line in the graph).
If you are in a medium-sized home theater or room, the dial in the 12 o'clock position will provide just the right amount of boost to work with your room gain in order to achieve a flat response to under 20Hz (blue line).
If you are in a small home theater or room, and the low end is just too much, turning the dial all the way left will dial back the bottom-end potentially cleaning-up your bass experience (green line). Measured results with each setting are shown below (each horizontal line is 1.0 dB).
