Our Top Pick: Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier

Features: Dayton Audio is a well-known manufacturer of sound devices. It creates high-quality items that withstand the longest in the market. One such device is the SPA1000 subwoofer plate amplifier. It is a cutting-edge gearbox amplifier that takes the best characteristics of Class G, Class D, and Class AB amplifiers.

Dayton Audio SPA1000 1000W Subwoofer Plate Amplifier has a Class G circuitry with the high-fidelity functioning of a Class AB amp. It also has a proprietary tracking down conversion power source that boosts efficiency to 86%. This means that you get unrivaled Class D-like performance with no difficulties with durability and great sound.

The Class AB output signal ensures distortion-free sound without the unpredictability that most high-efficiency amplifiers suffer from. The proprietary circuitry of this American-designed and constructed amplifier constantly tracks the input signal.

It takes it to modify or adjust the voltage available to the output stage. This tracking capacity delivers a precise amount of energy. This energy is delivered based on demand rather than maintaining it in reserve all of the time. This feature ensures that the output stage only pulls the power that is required at any one time.

More power is available for the subwoofer driver since less energy is wasted as heat. The SPA1000 is an improvement over previous models in terms of heat management, making it an almost bulletproof amplifier for today’s extremely HT audio and music playing situations.

There are several subwoofer amps on the market, but only a handful of amps are being produced for home usage. Plate amps often necessitate the addition of a sealed portion to the subwoofer box for optimal performance. Otherwise, they could be damaged by being shaken or air pressure could be driven out of switches.

Dayton is an excellent amp to be used at home or studio. The choice is yours and this machine can serve you well. It offers some very useful functions in addition to the conventional phase, volume, and crossover frequency controls.

Runner Up: Dayton Audio SPA250DSP 250W Subwoofer Plate Amplifier with DSP

Features: The digitally processed plate amplifier from Dayton Audio, the SPA250DSP, gives you complete control over your whole system. This one-of-a-kind amplifier enables you to fine-tune your program’s poor performance while also providing high-pass protection for your main supply.

This amp works against harm sustained by over-excursion. Dayton also stands behind its products, and their warranty proves dedication to quality and dependability. The Dayton Audio SPA250DSP plate amplifier is a solid performer for sure and can be used at home or at the studio.

Seven PEQ bands, a low-pass filter, a high-pass filter, a subsonic filter, phase control, a limiter, and a mains delay are among the DSP features. It has a Class D circuitry for reduced superior efficiency.

For flexible connectivity, the SPA250DSP provides different input low-level inputs and outputs. It contains PC-based GUI software that is quick and clever, allowing easier access to the DSP functions.

With special PC software used in the amp, it has a USB controller for PPC-GUI interaction. For the convenience of usage, it incorporates a single-knob control center so everything will be easy for you to control and adjust for the better.

Dayton has done a good job with this amp but some stuff is missing. This amp can only be controlled by downloading the program and connecting it to your computer through a USB cable. However, you will see that there is no USB cable included in the package.

The back wire, which is red and black, is too short and you might need to add some more cables. It will get difficult to get behind the sub and connect the wires to the terminals because to get behind the sub and connect the wires to the terminals is hard. This is a problem if you have a deep box or use the surface mount bracket.

Best for Budget: Sound Town Class-D Plate Amplifier STPA21-710

Features: You may use the Sound Town Class-D plate amplifier to create your own powered subwoofer box. Two XLR-1/4” combo inputs and two XLR outputs are included in the STPA21-710 power amp.

It can take a 500W RMS of electricity. The amp’s speaker outputs both produce 125W RMS power, allowing you to attach two passive PA speakers to it. The plate amplifier also has a polarization switch, a master volume control, and a Low Pass Filter modification.

The amp only works at 8-ohm impedance, and has a 1% THD and power consumption is 30W. The impedance of the amp is 8-ohm. The plate amp works with both 8-ohm and 4-ohm speakers. 

Based on the power output, the Sound Town STPA3L-400D may work out, but please double check if the dimension of the Sound Town plate amplifier (6.46″ x 3.54″ x 16.54″) can fit your system. Also, the internal dimension of the amp is 10.7 x 7.2 x 2.8″.

Keep in mind that some subwoofer’s back hole might be too small for this plate amp, so you will have to extend it somewhat. But, with a little elbow grease, you will be able to get your subwoofer up and running for less than the cost of a replacement part – and far less than the cost of a new subwoofer. 

This amplifier has good specs and is simple to set up and install. You can use Sound Town Class-D Plate Amplifier STPA21-710 to make a guitar FRFR combo amp. It operates silently, does not interfere with the signal.

It is well-built, and everything seems to be working in a nice way. However, providing product documentation either in the box or on their website would be a better way for customers to get the technical data they require.

Why do you need the best subwoofer plate amplifier?

A shallow-frame amplifier installed on the back panel of a speaker or subwoofer is known as a plate amplifier. It is a power amplifier that is mounted behind a speaker on a flat board or sheet metal.

It functions similarly to a standard amplifier in that it accepts a line-level input and amplifies it to power a speaker. The only distinction is that it has a low resonant frequency, making it perfect for driving subwoofers.

A plate amplifier is required to be installed inside a subwoofer’s container. The majority of ready-made subwoofers have built-in amplifiers. However, if you want to make your own subwoofer, you will probably need the best subwoofer plate amplifier.

Cutting a hole in the back wall of the sub and screwing the plate amp to it is the best approach to mount a plate amp to it so we recommend doing so.
