Buyer’s Guide

The difference between a standard and a plate amplifier is that there isn’t any real chassis in the second case. If you take the product and check its back part, you will see a circuitry, connecting to the plate for heat and a bunch of wires. In turn, the enclosure of the woofer or speaker becomes the box for it. Usually, subwoofer plate amps are made of aluminum, but they can be also be crafted with aluminum.

To tell the truth, such solutions have very much in common with regular amplifiers and perform approximately the same. What distinguishes them from alternative options is their cost-efficiency.

This will help you get a more hands-on experience and simplify operation of the system. Depending on the number of items you would like to connect to the amplifier, consider how many outputs and inputs (and of what quality) you need to satisfy all your objectives.

The quality of controls is also important. At least a two-band equalizer has to be present in the model to choose. It will enhance your abilities in the role of a sound message recipient and tune the performance to your liking without a difficulty. Besides, such controls as bass, treble, and phase filter will allow you to match the elements of your audio system. If users would like to vary the active point of the amplifier’s frequency performance, the top priority is not to miss the presence and functionality of the crossover function.

Which ohm-rate should I consider to pick up the best subwoofer?

Besides, it is one of the most spread options on the market. However, if you are looking for a device to hit as hard as possible, then the lower the number of ohms applied is, the better the expected result will be.
