The Dayton Audio SPA250 subwoofer amplifier produces 250 watts of clean power output, and combines with a host of flexible user options to make it an unbeatable choice. A user-configurable bass boost circuit creates a 6 dB peak at 35 Hz, which allows sealed subwoofer designs and certain ported enclosures to achieve their optimum bass extension and maximum "flat" output.
The SPA250 features RCA line level and banana jack speaker level inputs and outputs, automatic power-on that is triggered by any audio input signal, and a phase reverse switch to match the subwoofer to your room and your other speakers. A single amp can accept a stereo input signal and combine it into mono, which is preferred for sub bass reproduction. A preamp or receiver's LFE output may be connected to the SPA250's Left (mono) input. The internal low pass crossover is fully adjustable between 40 and 180 Hz, and of course the amp has built-in protection against internal and external faults.

Dayton Audio BST-1 Product Details
The human ear has the ability to hear a wide range of sounds, however, some sound is simply too low to hear and must be felt through the body. Feeling this extremely low frequency sound adds a new dimension to your listening, gaming, and movie experiences.
With a Dayton Audio BST-1 Bass Shaker installed in your home or auto sound system, you’ll feel those low bass notes or the thundering weight of a dinosaur’s foot slamming against the ground as it approaches. Your favorite action movies will come to life as you feel the cannon blasts and explosions impacting your body! If you’re into die-hard gaming the BST-1 Bass Shaker is the perfect addition to your gaming chair or couch! The power and impact of a football tackle puts you on the field and in the game! Feel the kick of your proton gun as it fires against the enemy!
Unlike subwoofers, the BST-1 Bass Shaker will not overload your listening area, and the perceived loudness of the BST-1 Bass Shaker improves listening at lower sound volumes. The engineers at Dayton Audio designed the BST-1 Bass Shaker to reproduce accurate, tactile sensations from your music and movie sound tracks. When a BST-1 Bass Shaker is installed on a resonant surface, it increases the portion of tactile sound as being "felt" beyond what is normally produced by subwoofers and ordinary speakers. Conventional subwoofers are traditionally considered optimized when you can feel rather than hear the bass. By using a BST-1 Bass Shaker in your system, this goal becomes easier to achieve -- enabling the subwoofer to perform at a more natural sound level.
A specially formulated nylon/fiber spider and the selection of quality hardware components allow the BST-1's internal motor structure to not only outperform the competition but increase the product lifespan. Simply put, with a Dayton Audio BST-1 Bass Shaker you can count on years and years' worth of amazing blasts, shakes, rolls, rattles, rumbles, thumps, bangs, and bumps!
