JBL LSR 305 Monitoring Speaker Review

Looking for the best affordably-priced monitoring speakers is now easier than ever, especially since there are so many quality options to choose from on the market.   JBL’s budget range are always worthy of consideration, particularly when the company leverages technology normally reserved for their high-end monitors. In fact, JBL has managed to put an exceptional amount of performance and value into the JBL LSR 305, which is one of the reasons why it’s so popular with home recording studios. If you’re looking for studio monitoring speakers that provide excellent performance without breaking the bank, the LSR 305 might just be what you need.

Features of the JBL LSR 305 monitoring speakers

The JBL LSR 305 has been regarded by many as a good-looking speaker, with some noting that it looks like Batman’s speakers (it’s up to you to decide if this is a good or bad thing, but we like the look of them!)  Utilizing an internal bi-amplifier, it has a magnetically-shielded 5” woofer and a 1” soft-dome tweeter powered by 41W Class D amplifiers fed by an active crossover. The woofer’s cone is made from a low resonance woven composite for rigidity. The smooth trim ring around the woofer allows for a smooth transition from cone to baffle. The woofer, along with the Neodymium-powered tweeter, delivers deep bass and a smooth high-frequency response for a monitor at this price. This monitor claims to have a frequency response of 43 Hz to 24 kHz and has a maximum peak SPL of 108 dB (C-Weighted).

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.

In terms of sound, these speakers produce impressive bass for their size and have a nice high-end too.  They provide excellent stereo imaging and depth which helps isolate different instruments in the mix.  While they sound great for a speaker of their price, their midrange can be a little weak when compared to other monitors (and at higher price points), however this shouldn’t prevent the home recording artist from achieving solid well-balanced mixes.
