Description
The Dayton Audio SA1000 is a freestanding, high-power subwoofer amplifier designed for the DIYer, installer, and systems integrator. This unique monaural audio device delivers the raw power of a pro-sound amp, but with the features and flexibility of a dedicated subwoofer amplifier. It can be configured for stacking with other audio components, and includes removable ears for mounting in standard audio racks (2RU). The SA1000’s patented tracking down-converter power supply ensures headroom for instantaneous power needs and the amp stays cool, thanks to its high-efficiency design.
A Class-AB amplifier configuration provides the SA1000 with clean and controlled output. From an application standpoint, the SA1000’s low frequency parametric EQ enables you to boost or cut to custom-tailor the sound to suit the listening environment. Sophisticated soft clip circuitry provides cleaner transient peaks while protecting your driver from over-excursion. The amp’s switchable subsonic filter removes subsonic information from the signal, which tightens the low end response of some subwoofer systems. On-board bass boost filters enhance LF performance while leaving the parametric EQ function available to address room modes, like cutting an excessively loud room resonance. The high-pass outputs provide a user the option to feed the signal back into their other audio components or a distributed audio system.
Manual, automatic on/off or triggered 12V input modes allow easy integration into automated systems. The stealthy pop-out knobs on the front panel make adjustments easy, while minimizing the risk of accidental disturbance. The SA1000’s subdued brushed black aluminum faceplate allows the amp to blend cosmetically with any type of audio gear. Accommodates RCA line-level inputs, includes insulated binding posts for the speaker outputs, and accepts a 12V trigger via a 3.5 mm mini-jack.

I have this hooked up to a single BK-LFE which is mounted to the frame of my 2 seater reclining theater chair (with a small console in the middle). This amp arrived very well packaged (as most amps generally are). It was easy to install and while it isn’t designed to be pretty it does look pretty good in person. It’s easy to hook up, power cable is thick and grounded. This provides enough power that I only have the gain set at 3 and it’s a lot of tactile response. The binding posts are very high quality. Only thing I wish it was was an LED light which wasb’t so bright. Not an issue if you mount it in a rack or another room. I will just use some tape to cover it up. If you hook it up a receiver using the LFE input you don’t have to play around with the EQ settings (which is nice). I have no issues with this getting hot even watching some movies with lots of LFE.

I have recently installed 8 BST-300EX and 2 SA1000 amplifiers into a bank of 4 reclining Paliser theatre chairs. Prior to the BST-300EX, I struggled to fit Buttkicker LFE into these chairs. The only mountable place for the BK LFE was the rear inner frame of the recliner itself, however this prevented the chairs from reclining. I went back to the drawing board and with the help of Smoke-tronics, I took a shot at 8 of these BST-300EX. This was a risk that paid off. Install was easy and these are so smooth and compliment the system very well. I would say 2 of these is pretty close to the output of a single LFE , but for the price you could do a 4:1 install and have way more than you’d ever need. I have 4 BST-300EX wired in a series-parallel configuration to maintain a 4ohm load at the amp which gives each BST-300EX 250w. I am beyond impressed with these and they have far exceeded my expectations, especially after the battle I had trying to get the BK LFE to work. I like these so much so that I am now looking at doing a family-room couch and my daily driver. The SA1000 amp is a nice unit and does what its supposed to do. I am very pleased with my purchase and experience dealing with Smoke-tronics. Thanks again!
