TThe ZV28 is a self-powered, self-processing, vented/direct radiating subwoofer with a large internal volume and a very low tuned frequency. The double-18 design offers a 25 Hz to 250 Hz (±3 dB) response, with peak SPL’s of 137 dB, thanks to 6,000 watts of onboard Class-D amplification and its 225-pound, 22.5-by-42-by-42-inch Helmholtz resonator, Baltic birch enclosure with tough, weatherproof high-pressure polyurethane finish. Protection systems and limiters control all manners of overload, including thermal, excursion and clipping.

20Hz Bass Performance at Concert Levels from US-Made Loudspeaker
The ZV28 Profundo from BassMaxx made its debut at the 2013 Ultra Music Festival in Miami. It’s also featured at Miami’s Treehouse venue. BassMaxx says the ZV28 Profundo can deliver consistently flat frequency response from 1 watt to 3000 watts, and that a pair of the units delivers response that is -3dB at 21 Hz with no equalization required. At UMF, moreover, only 16 of the units were required to serve up ample 20Hz bass to crowds of up to 10,000 people.
The ZV28 is a self-powered, self-processing, self-protecting, vented, direct radiating subwoofer with a large internal volume and a very low tuned frequency. Anti standing wave baffles and pass-through dampers minimize upper resonances while very large ports maximize low frequency performance at high output. Protection systems and limiters control all manners of overload, including thermal, excursion and clipping. The ZV28 is optimized for full-power operation. It is designed to operate at full rated RMS power throughout its operating range while ensuring the woofers remain within their excursion and thermal limits.
In short, the ZV28 delivers pure, deep and powerful bass to the very limits of human hearing, loudly, continuously and safely.
“We chose BASSMAXX after blowing up every other viable option on the market,” said Gregory Selph of Treehouse, Miami’s premier techno-underground dj venue. “These days, DJ’s demands on equipment are consistently surpassing the status quo of just a few years ago. Low end demands are the greatest, and often the weakest point in a sound system BASSMAXX is directly the opposite. BASSMAXX makes low end effortless waterproof drink proof DJ proof self powered self cooling self monitoring self limiting and just bass crushing all wrapped in a tight little package. Wheel it in plug it in ready to begin!”
With the ZV28, deep-bass response is available at high levels in real-world applications thanks to high sensitivity at low frequencies, robust components and prodigious power. Massive low end is consistently delivered when the prodigious power is applied. The ZV28 realizes consistently flat frequency response from 1 watt to 3000 watts. A pair delivers response that is -3dB at 21 Hz – no equalization required! The ZV28 does not have low-frequency EQ boost, which, at high levels, tends to result in excessive distortion or woofer damage rather than improved low frequency performance. The ZV28’s sensitivity is achieved and maintained though careful optimization, the use of premium components and innovative, proprietary thermal management techniques.
The ZV28’s woofer cones are waterproofed so the cabinets are safe to use outdoors where they may encounter rain, in nightclubs where drinks may be spilled on them, or in dusty environments. The ZV28 is remarkably lightweight relative to its output capacity, is solidly built and nearly indestructible. BASSMAXX cabinets are hand-made by master builders in the USA and warranted for a full six years to take extremely rugged work without damage or failure. BASSMAXX also features an industry-unique extended warranty, “Sound Defense”, which fully covers the speakers against blown woofers in the first two years.
The ZV28 Profundo Powered Subwoofer delivers what it promises: prodigious amounts of bass at high power, hour after hour, with no driver failures.
