JBL LSR305 Studio Bookshelf Speakers review

by admin on March 16, 2021

We have reviewed several of JBL’s speakers and headphones over the years. Many have touted the “JBL House Sound,” but we’ve never really talked about what that means.

When we first checked out the JBL LSR305 powered monitors a few months ago, we were thoroughly impressed by their amazing imaging and overall balance. However, we wondered if their unique sound stage would translate into something we’d want to listen to, or mix with, once we’d spent some more hands-on time with the speakers.

So as not to keep you in suspense we’ll just go ahead and tell you: the answer is an emphatic yes. JBL has managed to squeeze an impressive amount of value and performance into these speakers. Although they don’t do wireless streaming and require a different approach to set-up than your average shelf speakers, at $265, they could make for an enticing addition to your home studio, or your living room, you just need to sit on your sofa and relax with the fur pillows .

  • Features of the JBL LSR 305 monitoring speakers

  • At first glance, you’ll notice the LSR 305’s large horn flare tweeter, which is actually the company’s proprietary Image Control Waveguide. This technology is said to control the sound coming from the speaker in the horizontal and vertical planes, ensuring a neutral and accurate presentation at the listening position. It aims to manage dispersion to provide the widest sweet spot possible.
  • The LSR 305 also features JBL’s patented Slip Stream bass port, which is designed to keep port noise to a minimum while extending the bass performance at all playback levels. Another feature is the Linear Spatial Reference (LSR) technology, which employs 72 axis measurements to deliver superior accuracy regardless of the shape and size of the room.The LSR 305 offers adequate controls and connection points. The rear panel has XLR and 1/4” balanced TRS inputs, which accept professional +4 dB signals and consumer-level -10 dB signals. This allows them to be driven with various sources, from a professional DAC to an iPhone. It also has trim switches that provide control of the low and high frequencies, offering +2 dB, 0 dB and -2 dB settings for each.


The LSR305 are exceptionally good looking speakers, especially for their price point. Pulling them from their foam enclosure’s revealed sleek lines of jet black plastic, glossy circles around the drivers, and what we’ve described as batman-esque points surrounding the tweeters.

The LSR305 are exceptionally good looking speakers, especially for their price point.

ICW technology was leveraged from JBL’s super high-end flagship series, the $26,000+ M2 Master Monitors – just one of the benefits of having the resources of a company as big as JBL. And because it’s a physical manifestation rather than, say, digital circuitry, JBL was able to easily add it to these affordable speakers, helping to separate the LSR305 from other entry-level studio monitors.


The JBL LSR 305 is an excellent budget bookshelf speaker that may exceed your performance expectations for the price. It delivers high performance for very little money, and while there may be some compromises, they’re very minor for monitors in this price range. We at Studio-Speakers.com believe they’d make a great addition to your studio, and are good enough to produce some stellar mixes on.
