Sony XS-GSW121D
GS Series Subwoofer Driver

The new Sony GS series of subwoofers are the perfect way to get outstanding bottom end into your audio system. Whether you are expanding into a full-blown aftermarket setup, or are just looking to integrate better overall performance into your OEM setup, the GS Series has you covered. These drivers have been purposed-engineered to deliver outstanding sound quality and exponentially better overall performance over anything else in its price bracket.

The XS-GSW121D, specifically, is a 12" Dual Voice Coil subwoofer driver intended to deliver larger, yet controlled, "boomy" bass. Its large surface area allows it displace a lot of air to reach the desired low end frequency range. It is also able to accomplish this by maximizing the overall build quality, delivering a very solid 520 Watts RMS with an excursion peaking at 8.9mm. In addition, the XS-GSW121D has a very respectable Frequency Response range of 20 - 600 Hz, making it very easy to blend (crossover) into your Full-Range stage.


Premium Sound Requires A Premium Build


Premium Sound Requires A Premium Build


The XS-GSW121D single voice coil subwoofer driver cone is constructed using a Mica Reinforced Cellular Honeycomb design for reduced weight and increase rigidity, delivering deep bass response. A subwoofer's cone wants to naturally bend and warp due to the force exerted by the motor of the driver. If allowed the sound produced is Not accurate and of poor quality. The XS-GSW121D is engineered to counter act this, thereby delivering superb response.


Motor Design for Outstanding Output

Motor Design for Outstanding Output


The XS-GSW121D woofer uses a powerful, high energy Ferrite magnet to control cone travel and deliver outstanding power handling. The XS-GSW121D subwoofer is rated for 520 Watts (CEA 2031 rated), 420 Watts RMS and can handle peak power of 2000 Watts. This above-modest figure makes the XS-GSW121D perfect for a system starving for low end bass output. 500 Watts RMS will not shake a vehicle, but it will bring life to a bland audio system and deliver that thump we all love.



Maximize Power Delivery

Maximize Power Delivery


The XS-GSW121D 5-way gold plated binding post provide secure wire connections for high power handling. These terminals are capable of accepting a 10-gauge speaker wire to maximize power (Read: Wattage) delivery and performance. By accepting a slightly larger wire than most traditional 12" drivers, the XS-GSW121D is able to deliver more power than a traditional 12" driver. Moreover, the gaps in the stamped steel frame allow the driver to breath, greatly reducing the risk of burning out the subwoofer motor.

Good Concept...Needs to be expedited

The following review is for SonicElectronix-50-Gift-Card, which is a part of the bundle you are viewing.

I would recommend the virtual gift cards, however they do need to speed up the gap between paying for them and receiving them.

Nice...once I get it..

The following review is for SonicElectronix-50-Gift-Card, which is a part of the bundle you are viewing.

It's cool to receive this especially when NVX 27001 is kind of expensive (to me)...YOU DO HAVE TO WAIT 30 DAYS AFTER PURCHASE TO RECIEVE...keep that in mind.

Deal breaker!

The following review is for SonicElectronix-50-Gift-Card, which is a part of the bundle you are viewing.

I got this as a special with the JBL club 4505 amp and it's the reason I bought from sonic. No loyalties here I'll buy from whoever has the best price. With this card, sonic beat Crutchfield's price by 50 bucks. Glad I purchased! Used the card on some nvx sound deadner.

Great Bonus

The following review is for SonicElectronix-50-Gift-Card, which is a part of the bundle you are viewing.

I bought a really nice amp and got this $50 dollar e-Gift card free, what a deal. Haven't used it yet but it's loaded in my account and ready to use and will never expire. I know because of COVID their stock is low but I'm just gonna hold on to it and wait for a little because I'm sure the business will pick up in a little while, and they will restock and put out some great deals like I have been getting with stuff I really want.
