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.
