Most will also love the duality of the low-pass and high-pass functions.

With the low-pass filter, there’s no interference from high or midrange frequencies. With these removed, the bass output remains neat.

The high-pass filter is just as efficient. By keeping low-end frequencies away from the speakers, the sound comes out pleasantly.

This filter also serves another purpose, which is to keep the speakers safe from the excessive excursion.

“Since this system works with a PC, the lack of a USB cable is staggering.”

What We Liked

  • User-friendly interface
  • Powerful performance
  • Super easy to tune
  • Keeps the main speakers safe

What We Didn’t Like

  • USB cable not included

What to Consider When Buying Best Subwoofer Plate Amplifier

After checking the reviews, let’s get into the elements that make the best subwoofer plate amplifier.

Keeping this information in mind will narrow down the list of options to only a few. Then, you’ll be in a better position to pick one.

Power

Determined by watts, the power architecture of subwoofer amps may differ from one another.

Therefore, it’s crucial to determine which one will be the most suitable for your system. Here’s a quick guide on how to figure that.

  • Say you live in a small apartment. There’s no need for too much power, so going for a 150 Watts system may be the correct path. This will meet your demands, and it’ll do well in any application.
  • Alternatively, oversized rooms will do better with a subwoofer plate amplifier 500W unit. Of course, the biggest setback here is that the more power, the more expensive the unit is.

Build

Commonly, there are two types of subwoofer plate amplifiers that you could get: sealed and ported.

Each design works better for different circumstances, which means you have to be careful before picking one. Just like before, here are two examples of when to buy each.

  • If your purpose is to enjoy music alone, then you’ll need a sealed sub. These are tighter and have an overall better performance with songs.
  • On the other hand, if you want to use the system for a home theater, pick the ported plate amp. These display a fantastic bass extension that truly immerses you in action.

Design

Most of the amplifiers reviewed here have a sleek design with a black finish. This gives them a modern look that also blends well with most decorations.

As a result, the units are discreet and won’t get you out of the immersion.

But there are many more things to consider. For instance, having a compact amplifier is perfect for a cabinet-like setup.

This will fit in almost any location seamlessly, meaning you won’t struggle to make accommodations.

Lightweight is also another feature to consider. More so if you intend to install the system at an elevated height.

LEDs & LCD

These aren’t essential features per se, but they’re still nice to have in subwoofer systems.

An LCD screen keeps you updated on the sound performance, which you can use to adjust the unit as needed.

Usually, the LCD screens have a blue background and information about stuff like volume.

Then, there are the LED lights—these work as indicators to keep you updated on the status of the system.

Again, some systems may not even have these featured. It’s not necessary, but it sure makes the interface friendlier and intuitive.

Price

Subwoofer plate amplifiers aren’t necessarily cheap.

As with any other system, their price varies depending on several factors. That includes the power offered and the brand behind it.

While some units come at around $70, the most potent amps are above the hundred dollars.

This is why working on an estimated budget before considering your options is a must.

Also, stick to the most renowned brands. There’s Dayton Audio, Yung, Sismic, and many others.

These are popular for their great equipment but also due to their fantastic customer attention. If there’s any trouble with your purchase, they will most likely get right on it.
