Our JBL LSR310S Review

Are you looking for a new subwoofer?

The JBL LSR310S Subwoofer is the perfect speaker for anyone who wants to hear deep, dynamic bass at all playback levels. It’s packed with features that make everyday life easier, more entertaining, and more productive.

With its custom-designed driver delivering deep low frequency response into the 20 Hz region, 113 dB peak output, and professional balanced inputs and outputs with balanced XLR and 1/4-inch input, this subwoofer will be sure to deliver quality sound no matter what kind of music you are listening to!

What Is the JBL LSR310S?

The JBL LSR310S is a 200-watt subwoofer system that comes with a Mackie Big Knob monitor controller, as well as everything you need to enjoy great sound regardless of what you decide to do with it. If you have a dance club or you produce electronic music that has a lot of bass in it, this is the sub you need.

In fact, it is good for a variety of genres, including rock, country, and other types that don’t use a lot of bass in them. This is because the sub has a lot of range capabilities that nearly any musician or producer will appreciate.

The sub provides you with the ability to play in extended low frequency (XLF) mode, which essentially applies an EQ to the lower frequencies, resulting in a response that is no longer considered 100% flat.

Instead of a flat sound, the sub actually imitates the sound environment of your church’s sound system, even pushing the bass response to create a more extravagant sound. And while not necessary in a lot of cases, there is still the option of an external crossover switch that allows you to set your own crossover with your external gear if you prefer not to use the 80Hz crossover.

But most importantly, the JBL LSR310S subwoofer set provides you with a crisp, clean sound and some great technology that makes it operate and sound like speakers that are much bigger and much more expensive in price.

With an included crossover and a clean bass sound, pairing this 10-inch sub with small studio monitors provides you with the sound that you need to get great results every time. And at a price of around $460, you can enjoy a professional sound without paying thousands of dollars for it. You’ll get accurate higher volumes without the need to get any extra bass and an excellent “live” sound, among other things.

Top Benefits of the JBL LSR310S

The JBL LSR310S subwoofer system offers high-tech advantages you often don’t find with products in this price range. The Class D subwoofer is optimized for use in all of JBL’s 3 Series of speakers, making it a very versatile system. The 10-inch speaker combined with JBL’s Slip Stream Port work together to provide a peak output of 113 decibels.

This is a lot of power and strength for a subwoofer that is so small and inexpensive. There are also three crossover settings — 80Hz, external, and XLF — as well as an enclosure that allows you to use the subwoofer without fearing it will break or fall apart suddenly.

Included in the system is a subwoofer isolation stabilizer to improve the sound and resolution of the subwoofer. You can also use the stabilizer to reduce both unwanted resonance and unpleasant vibrations that tend to make the subwoofer sound muddy or incoherent.

There is a selectable input sensitivity and three crossover settings, allowing for the use of external crossover. These three settings include 80Hz, external, and XLF (120Hz). When you use the bundle, you get a great dynamic bass response regardless of which playback level you use.

And when you select the external low frequency (XLF) effect, you can augment low-frequency responses like the ones found in many dance clubs and venues. It also allows you to use the subwoofer to provide a sonic picture of how your tracks will sound once you get to that venue.

In practical terms, this means you essentially get a customized approach to your sound needs regardless of the type of music you perform, and JBL makes it super easy for you to enjoy all of this and much more. JBL even has a patented noise control filter that produces excellent sound regardless of the situation.

If you want a truly great bass sound from a car audio system or live performance speakers, you need a good subwoofer, and the JBL LSR310S subwoofer system is one of the best. The subwoofers made by JBL have a good reputation and with good reason.

You don’t always find subwoofers when it comes to sound systems, but they’re a great addition to any one of them. JBL subwoofer systems are also easy to install and easy to operate, enabling you to enjoy all of your favorite music, movies, and more complete surround sound the easy way.

Expert Opinion

As I have said in other reviews, don’t buy JBL because of the brand reputation. These are not the same JBL speakers of yesteryear. Harman, the parent company of JBL, has sacrificed quality for affordability. So understand you are buying a mid-tier speaker. Not top of the line.

This subwoofer is small. I don’t recommend using it in a medium to a larger venue. It will work for a small sanctuary or chapel. It is more designed for home theater than it is for pro sound but it will work.

Conclusion – JBL LSR310S Review

If you want a high-quality and efficient subwoofer but you’re on a budget, the JBL LSR310S subwoofer system is for you. It is easily found either online or in many electronic and car audio stores.
