Product Details

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.

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier
Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier is rated 4.6154 out of 5 by 13.
Rated 3 out of 5 by from Has some powerHad a 500 watt subwoofer from an Iowa manufacturer that no longer exists fail. The speaker was capable of handling more that 500 watts so I got the SPA1000. I had to cut the cabinet to make it fit but I was expecting that. After spending some time getting the amp to fit I was very disappointed. The amp rattled horribly. I ended up having to remove the amp and pull the cove to find that pretty much every screw on it was loose. After tightening them all up and putting it back together it works great. More than enough power for movie watching.

Rated 4 out of 5 by from Good valueI have a Niles Stage Front 15" subwoofer. The amp failed after three years. Niles discontinued this model and would not repair the failed unit. I contemplated replacing the entire subwoofer but this was cost prohibited at the time. I did not realize I could replace the amp until I found this Plate amp from Dayton Audio. It matched the power of the original amp and fit the original enclosure with some very slight modifications. I like the EQ adjustments on the amp and still need to tweak these a bit to reduce the boom but overall this is a great amp at a great value. Thanks Parts Express

Rated 5 out of 5 by from Great ampI used this amp in a 4cf sealed DIY subwoofer enclosure with the Dayton Audio 18" Reference drive and I could not be any happier. This amp has plenty of power. The parametric EQ makes it easy to blend with my front mains or if I just want to have ridiculous thumping bass.

Rated 5 out of 5 by from Great amp, massive power and no dirty bass.I used this amp for a custom subwoofer build and I am very happy. This amp has tons of (potential) power. It can be tuned to blend and harmonize with your other speakers, or you can really punch it and get the earth shaking bass for movies or music. This is a great amp and I am very happy with this product.* Project note:Yes, these are car audio drivers. I specifically chose them for their power handling and performance;•12" subwoofer with dual 4-ohm voice coils•polypropylene woofer cone with large-roll rubber surround•progressive spider design for excellent cone control•frequency response: 23-400 Hz•power range: 100-300 watts RMS (1,200 watts peak power)•sensitivity: 93 dB•top-mount depth: 6-3/8"•sealed box volume: 1.25 cu. ft.I also selected this driver because its cost is signifigantly lower than comparable theatre style subs with similar specs (plus they look much better than regular flat black paper cones on theatre style subs)I have these wired to 4ohms, and they have great response in the sealed box.*** I would love to post this in the "Gallery" but that page says "Coming Soon" when you try to add your own project.

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier

Please someone explain the thinking behind the 500watt and 1000watt amps not having an output RCA jacks for passive signal? I notice the lower wattage amps do. I need the output for bass shakers!

Upon purchase of the Dation spa 1000, I noticed "not for pro sound use" such as DJing and pro sound use & a 30%duty rating. Is this because of a small heat sink? Would increasing size of heat sink area increase the duty cycle and offer more of pro use? 

Asked by: spoodoc
Home audio subamps in general are not rated for a high power, continuous audio output as they will rapidly overheat. They are for the low frequency sound effects in movie soundtracks, which come and go. You can get move continuous power output by putting a fan on the heatsink, but I would suggest monitoring the amp until you have a feel for what it can take before getting scary hot. For DJs and bands, an amplifier intended for the application would be a better choice.
