Throw Thunderous Lows with Cerwin-Vega's Huge 21" Powered Sub!

Reach 2400 Watts peak with the booming Cerwin-Vega CVA-121X powered subwoofer. This 1x21-inch baddie completes any serious PA system, giving bands and artists the low-frequency response and tremendous power they need to play loud. Really loud. What fuels the subwoofer's fire is Cerwin-Vega's Stroker technology, which maximizes power output and efficiency in one go. If you're in need of some low-end thunder to blast away your audience, turn to the CVA-121X.

Plenty of Thump for Your Powered PA

This active subwoofer sports a huge 21-inch woofer and a powerful Class H amplifier that's able to output 1200 Watts (continuous)/2400 Watts (peak). Cerwin-Vega's CVA-121X just begs to be pushed to its limits! The built-in amp features its own parametric equalizer -- a helpful addition that lets you tweak gain, frequency, and resonance (Q) to suit your performance venue. All in all, the powered sub delivers a terrific low-frequency power boost to any live set, with the user-friendly controls you need to take command of it.

Efficient to the Extreme

The CVA-121X is driven by Stroker technology, which uses a three-spider driver design to optimize cone excursion and voice coil efficiency. More than just a pretty face, the sub's cast aluminum grille serves double duty as a speaker heat sink, so that the woofer can perform at its best for hours on end without overheating.

Quick System Setup

Easy to set up, the powered subwoofer offers a range of mounting and connection options, including both XLR and 1/4-inch connectors allow for balanced and unbalanced operation, and Master/Slave output connectors for daisy-chaining multiple CVA subwoofers. Three top-mount 35 mm pole sockets and matched mounting accessories further help you configure your sound system. Removable casters help you roll the 180-pound behemoth from place to place.

Product Description

The CVA-121 offers tremendous power output and exceptional low frequency response. The CVA-121 represents an industry milestone, as it is the first 1200-watt, 21-inch active subwoofer. At the heart of the CVA-121 is Cerwin-Vega's patented Stroker(tm)(r) Technology, which utilizes a three-spider driver design to optimize cone excursion and voice coil efficiency. Even the unique and striking cast aluminum grille doubles as a speaker heat sink, enabling these woofers to play longer and harder than anything else in their class.

Matched to this woofer is a powerful, built-in 1200-watt (2400 watt peak) high-efficiency Class H amplifier. The CVA-121 amplifier includes a unique onboard parametric equalizer that allows for added adjustment of gain, frequency and Q for maximized control and output. Integrating all these technologies allows the CVA-121 to deliver best-in-class low-frequency output from a 21-inch speaker, but has a footprint more like an 18-inch box. The result of all this integration is power, upgradeability and improved portability.

The CVA-121 has a complete array of connection and mounting options. XLR and 1/4" connectors allow for balanced and unbalanced operation, accommodating a wide variety of cables and configurations. Master/Slave output connectors allow users to daisy-chain multiple CVA subwoofers for precise control from the master unit. Finally, three top-mount 35 mm pole socket and matched mounting accessories, provide for flexible full range system configurations.

Protecting your investment is solid 18-mm hardwood construction. Bottom line; the CVA-121 Active Subwoofer will provide you exceptional performance in a package that's small and easy to use.

Features:

- Custom 21-inch woofer with Cerwin-Vega's legendary Stroker technology, using a three-spider driver design
- Built-in system amplification optimized for the 21-inch woofer
- Master/Slave Output allows for daisy-chaining multiple subs reduces cable connections
- Onboard Parametric Equalizer allows control of performance output by control of the gain, frequency, and Q
- Cast aluminum grille protects the woofer and acts as a heat sink by reducing power compression
- Rugged hardwood enclosure and removable casters reliable from gig to gig
- Three top-mount industry standard 35mm pole sockets accommodate single or multiple CVA-28s using the CVA accessories

4.5 out of 5 (21 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "cva 121 in action"
Overall: Since most reviews i read are either misleading or lack in details i decided to place a review on this sub that everyone can understand. I spent a lot of time researching powered subs for our needs...it was frustrating due to mixed reviews on practically every one of them...so in the end we basically did a hail marry and went with the original sub kings Cerwin Vega..we ware glad we did. The use for these subs for us is for both DJ and band use. We gave them a go last night for the first time and i have to say these are fantastic subs. They hit very hard, and got special attention from our female clientele ;). The gig was in an 80' x 80 building and was more than enough. We drove them about 50%sub gain...and 40%on the mixer... and it was all we could take. We are big Bassnectar fans and wanted extremely low and powerful bass ...and we got it in a powered package. It felt as though the building was going to fall apart bolt by bolt...brick by brick. We have been let down in the past in purchasing equipment by relying on reviews, our most recent mistake was investing in EV powered setup with subs......which proved to be less than impressive ....but the reviews about them had nothing but praise and hype. There is no hype when it comes to the cva121...it really delivers. I cant speak at this point about reliability, and the speaker itself is heavy as h....heavy....did i mention it was heavy. Plan on getting some cheap carts with big tires to make your life easier....the included caster wheels are nice but we wont be using them.. due to the speakers weight the caster wheels would hang up on every crack and crevice and make life hard not to mention all the rattling and jarring of the built in amp and all its sensitive contents . Even though the thing is heavy, it is very well made and most options you could ever want or need as far as control and input.

zZounds has verified that this customer bought this product from us. "I don't care what it was made for."
Overall: I received the box on a palette on 1/6/15 after ordering on Christmas night 12/25/14. Quicker than expected since I went through two holidays and two weekends.When you ship this item freight you can't really track it like Fedex or UPS, it will only show processing even after you recieve it. The box was in great condition and was completely wrapped in saran wrap. Inside it was well protected with more extra thick cardboard and styrofoam.If you get your saran wrap or box damaged make sure you investigate inside the box first before signing the paperwork. Once you sign for it you pretty much release the carrier of any liability during the shipping process. Well thats what it says on the Cerwin Vega box. I had the driver fork lift it into the garage and after examining it I signed for it. He offered to dolly it into my bedroom so I let him do that and gave him a tip. Only way to get it out of the box without destroying the box was to lay it on its side and pulled it out. There are 4 heavy rubber feet at the bottom of the sub that are about 3/4" thick and would be ideal use on hard flooring. It came with a 5' standard 3 prong black power cord the same one's computers use and four casters ( 2 fixed and 2 swivel ) each wheel is hard black rubber and a wheel diameter of 3" the castor would add 4 1/2 " to the depth of your sub if you screwed them on. They are pretty heavy duty at 2 pounds each that you would need to screw in with 4 screws each so a power drill will be nice there. Since I will not need to move it again I opted not to use them. It is heavy but not so much as to not be able to move it around without the castors. So since it will be stationary, it could weigh 400lbs I don't care. It has all the controls recessed in the back all the knobs are easy to turn and feel solid. Also has a very large heatsink in the back for the amp which I will never utilize since I set mine on 2 or 3 on the gain. I wanted to improve the bass coming out of my computer. I like to listen to my mp3's, games, midi's and movies. I have not done anything since 1993 when I bought a pioneer vsx-9700s receiver and a pair of pioneer TZ-9's. Everyone at best buys and fry's pointed me to the bose systems with the sub but to me they sounded like little speakers trying too hard to be big. My TZ-9's sounded better anyway. I want to hear music as though I'm there live in a concert where they have monster speakers that you can feel! Then I came across a thread about someone who asked "why not use a CVA 121 for home theater?". It was either audiohaulics or hometheater.com . They didn't recommend it because it didn't go low enough for HT. They told him this speaker was for proffesional use only that you find in clubs, churches, concerts etc.. Matter of fact almost everyone recommended me not to get it for home use. I thought I like the way music sounded in clubs and concerts so I pursued the cva 121 which eventually landed me on zzsounds. I knew I had found the right place with the right equipment. I researched every PA subwoofer they sold and decided on the cva 121. The real clencher was due to learning that in a bedroom the cva 121 could make your ears bleed and cause brain damage as well as it being a leading cause of post traumatic stress disorder when in such a confined space. So it was a no brainer for me. I was thinking about the CV TS42 but you have to be about 8 feet away at least for the full sound wave to develop and since it's sitting next to me and the computer I needed something that would be fully developed when the sound leaves the speaker. With that being said everything was very reasonable and the cva 121 was a steal. I am so glad I did and that ZZsounds sells all the cables needed to adapt my computer to the cva 121 via a 1/8 TRS to Dual 1/4 TS and my home reciever via a Dual 1/4 TS to Dual RCA connectors. I was a little worried about line noise since i was going to be using lots of unbalanced cables but after plugging everything together there was ZERO READ MY LIPS 0 = ZERO HUMM I was very very pleased. I as ready to order that line zapper if need be. I set the crossover to 85HZ and let my TZ-9's take the top end. Let me tell you this my friend, the first music I played was a live concert DVD from Madonna's 1985 Virgin Tour, I felt like Iwas 15 again when I was there live! It was sooooo (explicitive) great, everything I imagined could be felt in the music like I was at the concert. You get that big concert sound that cannot be replicated in home systems. It has solid endless bass in all the right frequency's that matters the most!! I tried it out on my good old handy Roland MT-32 MIDI module and it sounds awesome! I love the percussion, taiko, koto and timpani are just the best on the mt-32! I don't care what or who this was made for it sounds a hella a lot better than anything else I heard. Only thing I would change is having the controls on top or front of the sub. I know its made for PA but thats not what I'm using it for and its on my wish list. I might try turning it around and let it bang the back wall to get easy access to the controls but I don't know how it would sound. And SIZE DOES matter... well that's what she said. Sorry Bose!! If I'm wrong than I don't wonna be right!
