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.

Dayton Audio SPA1000
Dayton Audio stands for speaker excellence
Dayton Audio has been designing and manufacturing high-quality audio components for more than 20 years. The brand has made a name for innovation, high quality, and values. The products of this premium DIY audio brand are produced in North America, Europe, and Asia. Dayton Audio products have received acclaim worldwide throughout the years and are often compared favourably to similar items costing far more.
Dayton Audio woofers
The dominant component in a majority of loudspeaker designs, woofers are responsible for much of a system's tone and character. Don't underestimate this cornerstone element—Dayton Audio has the perfect woofer for every application and budget. Discover some of Dayton’s high-quality audio woofers, such as the popular Dayton Audio Ultimax UM18-22 from the powerful Ultimax Series, the Dayton Audio RSS390HF-4 featuring ultra-low distortion or check out the never-failing Dayton Audio PS95-8 full-range woofer.
Tweeters from Dayton Audio
Although they are the smallest driver in most loudspeakers, tweeters play an important role in our auditory information perception. Clarity, articulation, imaging—Dayton Audio tweeters make your speaker system come alive! Discover the immense popular Dayton Audio air motion tweeters and dome tweeters! Dayton Audio tweeters, such as the Dayton Audio AMTPRO-4, provide ultra-clean, detailed, and dynamic treble output.
Dayton Audio Drivers by Series
Dayton Audio has created a comprehensive selection of speaker components for every application and budget, all of which you can find at Nonsolospeakers. Find some of the Dayton audio most popular driver series below.
Dayton Audio Reference Series
Dayton Audio's Reference Series is dedicated to the pursuit of supreme low-distortion high fidelity audio reproduction. The Dayton Audio Reference RS100-4 for example comes with a rigid yet lightweight anodized aluminium cone, enhanced motors with distortion-reducing devices, and carefully optimized T/S parameters result in accuracy and detail that are second to none.
Dayton Audio Designer Series
The Designer Series by Dayton Audio was developed specifically with the speaker designer in mind. It is an affordable, attractive line of drivers that puts performance first. Careful engineering ensures that the Dayton Audio DS135-8 5" Designer Series Woofer can handle full rated power at the lowest possible frequencies—without exceeding Xmax. The series combines useful performance parameters with elegant style.
Dayton Audio Ultimax Series
Most low-frequency drivers smear, distort, or alter their input waveform. Ultimax DVC subwoofers by Dayton Audio, such as the Dayton Audio UM12-22 woofer, sweep a higher volume of air while preventing false, deceptive reproduction. They are designed to deliver powerful low-end response from modest-sized enclosures.
Dayton Audio amplifiers

Dayton Audio Exciters & bass shakers
Exciters are compact devices that attach to surfaces and vibrate them mechanically. The vibrations translate into auditory information; the result is surprisingly musical and accurate. Test them on doors, ceiling panels, windows, projection screens—whatever excites you! Check out some of the brand's most sold exciters and transducers, such as the Dayton Audio DAEX32EP-4, DAEX30HESF-4, and the BST-1 bass shaker!

The Dayton Audio B652-AIR 6-1/2" 2-Way Bookshelf Speaker with AMT Tweeter Pair, for example, are known for their pleated ribbon diaphragm AMT tweeters that add an extra portion of smoothness to the already overall great sound experience. Dayton Audio B652-AIR speakers take a big step up, thanks to the addition of a higher-quality AMT tweeter. The AMT's folded Kapton ribbon diaphragm moves more air but with less effort and distortion, for purer and satisfyingly dimensional sound.
