Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier
The Dayton Audio SPA1000 is 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.
Specifications: Rated power output: 497 watts into 8 ohms, 950 watts into 4 ohms with 0.92% THD (based on one-third power duty cycle) S/N ratio: 98 dB (A-weighted) Low-pass crossover: 30 - 200 Hz, 24 dB/octave Parametric EQ: Frequency: 18 - 80 Hz; Bandwidth: 0.1 - 1 Q; Level: -14.5 dB to +6 dB Phase Adjustment: 0° (NOR) or 180° (REV) Input impedance: 12K ohms Input voltage: User switchable 115V/230V (Euro cord available) Stand-by power rating: 115V 24W; 230V 18.4W Efficiency: 86% Net weight: 17 lbs. Dimensions: 11-15/16" W x 11-15/16" H x 5-1/4" D; Cutout dimensions: 10" W x 10" H.
With a Dayton Audio 5 year warranty, it's more than a guarantee, it's a promise. We stand behind our products and our warranty is a demonstration of our commitment to quality and reliability.

So I purchased this to replace my Klispch 115 SWR amplifier after it died. The difference is night and day as far as features, build quality, and power goes. I doubt the Klispch stuff makes more than 250w with lightening as a power supply. This SPA 1000 is definately worth the price at about .50 per watt. Not too mention the clipping protection, great EQ, and AB class with a massive Xformer.I actually threw the Klipsch woofers in the trash where they belong and installed Sundown subs. The house is now powered with 3 of these amps on Sundowns in Klipsch enclosures. What a difference!

Very clean sound, with no clipping or distortion. The on-board equalizer eliminated my 15 Cerwin-Vega subwoofer enclosure's reverberation excellently. It cut only a very narrow frequency band to cancel out the excessive cabinet vibration.I thought a 1,000 Watt peak amp would be louder, but this amplifier subwoofer combo still significantly outperform both of my 15 3-way C-V floor-standing speakers, so I guess I should be content. The three-some sound fabulous together. Definately a strong 4 stars for this Dayton plate amp.

Used one of these 1000w amps with two 12 Polk Dxi subwoofers for a dyi home theater subwoofer.Pros : I really like the subwoofer controls and eq although I ended up using the LFE input which bypasses all controls except the gain. Very well built with a beefy transformer. Auto power on sensing seems to work well so far.Cons : Nasty thump when powering on(not when auto sensing though). Would be better if a 12v trigger option was offered.
