RSL Speakers Speedwoofer 12S Subwoofer Giveaway!
"We Review it, You WIN It!" is the only Audioholics Contest that sends one winner the review model. Tested and approved for full serviceability, the winner will receive the very unit that played a starring role in an Audioholics review. The otherwise brand new unit is resting in its original box, but already put through the paces in our rigorous testing. Welcome to the RSL Speedwoofer 12S Sub Giveaway!
Note: Since this was our review unit, some slight cosmetic blemishes are to be expected, but the unit is 100% fully functional and tested.
Our giveaway this summer is from an audio company that needs no introduction on Audioholics. RSL Speakers has made a name for itself with high-end loudspeakers at surprisingly reasonable prices, you'll find something in its lineup for everyone at any budget. Last year's Speedwoofer 10S MKII sub impressed Audioholics reviewer, James Larson so much that it was awarded the 2022 Product of the Year Award in the budget sub category. This year, RSL has followed up with a bigger and badder sub that reaches down to even lower frequencies. The 12S Speedwoofer brings potent, musical bass from 16-Hz to 200-Hz at +\-3dB with 500 watts RMS < 1% THD and 1550-watt peaks. Our testing confirmed the 12S has class leading 16Hz output in its category.

RSL Speedwoofer 12S Subwoofer
The Speedwoofer 12S is RSL's latest powered sub and an evolutionary step forward in the company's Speedwoofer line. The 12S is more than just a larger Speedwoofer 10S that delivers bigger, deeper bass than its 10-inch counterparts. Speedwoofer 12S is named for its 12-inch driver powered by a 500-Watt RMS XDR-Series class-D amplifier capable of delivering 1500-Watt peaks when the soundtrack gets demanding. Like previous Speedwoofers, the sub employs RSL’s patented Compression Guide Technology, a porting system that enables greater transient response than other ported subs. The driver/transducer is also built to the usual high standards of RSL's Speedwoofer line with a cast aluminum basket and Kevlar-reinforced paper cone driven by double-stacked magnets in its FEA-optimized motor.

12S Speedwoofer Evolution
Besides presenting a larger box-size, there are some improvements in the 12S Speedwoofer design outside of adding a couple of inches to the driver size over the 10S. RSL has tuned the 12S frequency response to go significantly deeper with even lower bass extension than 10S. According to Jame's testing, documented in his Speedwoofer 12S review on Audioholics the new sub is capable of...
...plunging down to a subsonic 16Hz within a +/-3dB window. The driver uses two mirrored spiders whereas the 10S only used one spider. The advantage of this is that the moving assembly of the driver will be much more restricted to a single plane of motion, and this will help to reduce distortion and also protect the voice coil former from hitting the interior sides of the motor. By mirroring the spiders, any non-linearities on one side of the spider’s travel are negated by an inverse motion, and this design should help to reduce even-order harmonic distortion products. The amplifier of the 12S uses a new heatsink technology for greater thermal efficiency and capacity. There is also a front-mounted LED meter that can show levels for volume as well as display muting or DSP modes. This is useful because the 12S comes with a remote control, so the user can see what adjustments are being made on the sub itself. These are just a few aspects that should make the Speedwoofer 12S a qualitative improvement over the Speedwoofer 10S as well as a quantitative one.
One thing you can count on with the Speedwoofer line is that RSL does NOT shirk the provision of a remote control, couch potatoes everywhere rejoice! It's a simple remote that lets you intuitively set volume and the Speedwoofer amplifier's sophisticated DSP settings. Honestly, playing with DSP settings on a sub can bring hours of fun with sighted A/B bass-response comparisons using your favorite movie scenes or songs. And RSL's XDR-amp has all the subwoofer DSPs you'd need. What follows are just some of the Speedwoofer 12S specifications. See RSL's product page for the full rundown.
