WHY CHOOSE A VS21 SUBWOOFER?

Love in your face bass with big chest thump?
This is your cab.

Versatility that covers every genre, with massive punch and plenty of heft. Excellent transient response is delivered by the efficient performance of the horn at the upper end of the subwoofer range. Fits in the same space as the CVL36, and gives you exponentially more BOOM.

The resulting impression is a very big, heavy hit. Extended depth is delivered by the large acoustical volume, low tuning and the massive displacement of the long-excursion 21″ woofer.

Such a game changer! :)”

Don’t hold back!

BASSBOSS subs are optimized for full-power usage.

Multiple proprietary protection technologies ensure that the woofers remain within their excursion and thermal limits, so they don’t break or burn like other subs. BASSBOSS provides much higher levels of deep bass than mass-market subs, reliably.

With plenty of headroom to keep up with the most enthusiastic crowd and not run out of bass.

So turn it up, and keep it up. BASS is good for you.

Specs

True Specifications

BASSBOSS technical specs are based on measurements of continuous performance in normal usage. Other manufacturers may specify output based on calculations rather than measurements; measurements outside the operating bandwidth; or on ‘Burst’ or ‘Peak’ readings.

BASSBOSS specifications are conservative compared to most manufacturers. They reflect what the products will achieve, consistently, in the real world. Since the real world is where you’ll be using your gear. 

Read more about BASSBOSS Designer David Lee’s specifications philosophy on ProSoundNetwork.

Our proactive philosophy causes specifications to be subject to change whenever improvements are made.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specifications that are inflated over what can actually be achieved. BASSBOSS real world output specifications are provided as “Maximum Sustained Output” ratings, which reflect actual measured, continuous output levels.

Hand-Built Cabinets

The VS21 is a vented short horn hybrid single 21″ subwoofer. It is rear-loaded into a large acoustical volume that is tuned to a low frequency, and front-loaded onto a short horn. The vented enclosure section provides extended low frequency performance and the horn section provides increased upper frequency sensitivity and improved transient response.

BASSBOSS cabinets are hand-assembled in the USA. Constructed from 18mm Baltic Birch plywood, using dado joints, screws and advanced composite adhesives.

A top-mounted pole socket in each VS21 provides for mid-high loudspeakers to be mounted on a straight speaker pole above the subwoofer. The enclosures feature four large rubber feet on the bottom and four on each side, with corresponding recesses in the opposite side to facilitate interlocking the boxes when stacked.
Arrays of multiple boxes combine to devastating effect. With rubber feet on 4 sides, the VS21 can be stacked and interlocked in blocks of 4, 6 or 8 boxes with the horn sections coupled for increased impact. The feet on the bottom and back lock into the V transport carts and the feet on the sides lock into the H transport carts.

The VS21s can also serve as a ground-support platform for the LA88 Line Array. (With optional hardware.) The VS21 is an extremely versatile loudspeaker not only for multiple applications and genres but for expansion as well. Start with 2 and grow to 32, there’s nothing you won’t be able to do.

Prodigious Amplification

A 2400W RMS amplifier with integrated, comprehensive DSP is included. The amplifier is rated for RMS output using continuous sine wave signal.

This is not a Peak or Burst power rating. BASSBOSS uses only continuous RMS power ratings because you’re not going to be using your sub in millisecond bursts. For subwoofer applications, Peak and Burst power ratings are largely irrelevant.

The amplifier is capable of delivering 2400W of continuous output. This ensures the amp isn’t the limiting factor in the output of low frequencies. Providing abundant power prevents overheating issues and virtually eliminates the damage that clipping a too-small amp can cause.

For larger events, several arraying options are available. Block arrays, side-by-side arrays and front/back Cardioid arrays can be deployed securely thanks to the interlocking feet. Presets are included in the DSP.

Rugged Drivers

All that electrical power is converted into acoustical energy by a 21″ Neodymium motor woofer. This premium-quality, driver features split-wound 4.5″ 4-layer copper-clad aluminum voice coil, and peak-to-peak excursion capability of up to 60 mm.

High-intensity Neodymium magnets are lighter and provide higher efficiency so the result is a lighter and louder cabinet. Split-wound coils produce a more linear force through the range of movement of the cone, which results in lower distortion and improved linearity at high output.

The cones are waterproofed to protect them from possible, accidental exposure to moisture such as rain or spilled beverages. Waterproofed woofer cones also permit the cleaning of drivers that have been soiled in a dirty or dusty environment with the use of a damp cloth. Keep the amplifiers dry and party on!

Waterproofed cones in all products. Optional weatherized and weather resistant loudspeakers have the same acoustical performance as our standard options. If your system is likely to be exposed to rain, ask about IP rated amplification options. If you have need of a system for outdoor installation, ask about Weatherized products.

Focused Tuning

BASSBOSS subs can be connected directly to your mixer with nothing but signal cable in between. The built-in processing is comprehensive and yet minimal manipulation is applied to the signal. The processing includes only a high pass filter and a low-pass filter. There is no need for any EQ in the signal for the speaker to provide a broad, flat frequency response. A sophisticated limiter system protects the woofer from thermal and over-excursion damage.

Plug-and play with peace of mind. Multiple, sophisticated protection systems make the loudspeaker virtually indestructible. You can turn on and turn up, all night, without fear of over-driving to the point of damage.

Reviews

I love this thing!

Tracy Barnes

I gigged for the first time and let me tell you, this thing hits hard. I can not wait to gig with it again and to get a second one.

The Bassboss team is the best bar none. They provide great customer service and answered all the questions I had.

Ahhsome!

Wes Berry | Wes Berry Productions

Here’s a run down on some recent shows I did with 1 to 4-VS21 subwoofers. 1-cab with my small line array, sounded great and good coverage. 1-cab in a theater with my small array, for play back, more than plenty, added great bottom and richness. 2-cabs acoustic show, ahhsome! had a lot of people comment on how every thing could be heard and felt. Fair grounds, 4- cabs, covered the entire grand stands you can’t see up to the nose bleed seats, every one was impressed. 4-cabs, tried stacking on side, (no time to dial FOH in) was a little disappointed at first, the kick was there but not what I was expecting, it was there but no push (must have been limiting), had a crew member crawl behind to check and found the audio tech (me) forgot to turn the right side two on What a difference, in this set up it was the best over all impact coverage everywhere, and seemed to have plenty of head room. I always have them on a aux out, they sound great on up right bass, you can get all the rich sound and feel from the low strings.

I want more!

They are insane! They sound so great now I want more! 🙂

Game Changer

Greg Ceniceros | Kong’s Bar, Lubbock, TX

Everything is going great here and everyone is loving what we have going with the VS21. I It always makes me smile when the sound turns on. Such a game changer!

5-⭐️ treatment for sure!

Caleb Burton | Rize Entertainment-Texas

This year we introduced the good folks attending the 7th annual Unite as One beach clean up and music festival to the deep bass that only BassBoss can deliver. Looks like I’ll be saving up for the DV12’s because the wall of tops we were running didn’t even come close to keeping up with the VS21. Our stage received compliment after compliment and the bass was at the top of the list. Thank you Bassboss, you will be hearing from me again soon.

The entire BASSBOSS team has been great. David Lee took the time to speak with me at length by phone prior to my purchase, and his team has reached out to me since to check on things a few times. 5-Star treatment for sure.

The sound was unreal

Micah Blotter | Surr3alSound

You might be hearing about this party in the future man, I’ve never seen anything like it. It was a private party for 50-100 people at a private campsite at Lake Shasta, where everyone knows each other. There was also no cell service. It lasted 3 days and nights of non-stop music and jet skiing and floating on the lake.

I so much appreciate everything you guys did to help me out. The sound was unreal, and veteran electronic music peeps were blown away with the quality of sound and the power of the VS21. It seemed like it shook the whole mountain.

Blown Away

djtechnical | Events Pro DJ

@bassbossbass This car show was at an old airport they transformed into race tracks. The bass from 2x VS21 Subs carried well over 300 feet. I was blown away by how it still sounded clear so far away. Obviously that far away the bass was no longer loud but it was still clear!
