The Dayton Audio SA1000 is a freestanding, high-power subwoofer amplifier designed for the DIYer, installer, and systems integrator. This unique monaural subwoofer amplifier 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 patented tracking, down-converting power supply ensures headroom for instantaneous power needs and operates cool due to its high-efficiency design.

A new animal is prowling the subwoofer amp jungle! Behind the less than 10" x 10" faceplate lurks a tiger of a 240 watt amp, ready to unleash its power on your subwoofer driver. Includes all the features that you have requested, like a choice of RCA line level or banana jack speaker level inputs and outputs, automatic turn-on that is triggered by an 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 optimum for sub bass reproduction. 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. Unleash the beast! Dimensions: 9-13/16" W x 9-13/16" H x 5" D. Cutout dimensions: 8-1/2" W x 8-1/2" H. 

This ultra-compact 25-watt subwoofer amplifier offers the perfect amount of power for any small subwoofer system. It delivers a real 25 watts RMS of power, which is not an exaggerated figure like found in most typical multimedia systems. With a solid 25 watts, it has enough oomph to reach 100 dB with many drivers. Measuring only 6-1/4" square, the 25-watt amp will fit in even the smallest enclosures. Specifications: Measured power output: 15 watts RMS into 8 ohms 0.1% THD, 25 watts RMS into 4 ohms 0.2% THD. Signal to noise ratio: 90 dB (A-weighted). Dimensions: 6-1/4” W x 6-1/4” H x 2-1/2” D. Enclosure cutout: 5-1/4” W x 5-1/4” H.
 

ayton Audio SPA250 250 Watt Subwoofer Plate Amplifier

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.

With 70 watts of clean power and a full feature set, this amplifier offers exceptional performance and value. A class-AB output stage and a large power supply section give this amplifier great sound quality, and enough power to drive most compact subwoofers. The auto-on circuit and sealed rear enclosure make this amp excellent for upgraded computer subwoofers, and also for driving individual tactile transducers. Don't let the modest price tag fool you-- this is a workhorse amplifier that delivers just the right amount of power. Specifications: Measured power output: 45 watts RMS into 8 ohms  0.1% THD, 70 watts RMS into 4 ohms  0.2% THD. Signal to noise ratio: 90 dB (A-weighted).

 

-NEWLY RELEASED MODEL- One of the most technologically advanced subwoofer amplifiers on the market today! The Dayton Audio SPA1000 subwoofer amplifier is based on a state-of-the-art Class G circuit topology that combines the proven high power, high fidelity characteristics of a Class AB amplifier with a patented tracking down converter power supply to achieve an operating efficiency up to 86%. You get the efficiency of a Class D amplifier without compromising audio quality and reliability. The Class AB output stage provides the clean and low-distortion sound that audiophiles demand, without any of the instability problems that plague other high-efficiency amplifier designs. This American-designed and engineered amplifier uses patented circuitry that continuously tracks the input signal to modulate or control the voltage available to the output stage. This "tracking" capability delivers the exact amount of power based on demand instead of constantly keeping it in reserve, so the output stage only draws the amount of power that is required at any given time. Less energy is wasted as heat, and more power is available for the subwoofer driver. With its enhanced thermal management, the SPA1000 is an upgrade over previous models—making it a nearly bulletproof amplifier choice for today's demanding HT audio and music playback applications.
