Gearank High Notes

The JBL LSR305 in particular continues to get rave reviews from experts and users alike, who appreciate its quality and versatility, even though they are mainly available second hand these days.

Housed in its injection-molded ABS baffle is a 5" woofer and a 1" tweeter, that's bi-amplified by dedicated 41W amps. It's most notable feature is its wider center image, thanks to its distinctly designed wave guide, which allows sound to disperse more consistently across a broader area.

Other features include magnetically-shielded transducers, and JBL's patented Slip Stream port design that improves bass response.

JBL LSR305 Specifications:

  • Driver: 5" Woofer, 1" Dome Tweeter
  • Amplifier: 41W LF, 41W HF
  • Inputs: 1 x XLR, 1 x 1/4" TRS
  • Frequency response: 43Hz-24kHz
  • Crossover Frequency: 1725Hz
  • Enclosure: Ported
  • Controls: Input Sensitivity, LF Trim, HF Trim, Volume
  • Dimensions: 11.75" x 7.28" x 9.88"
  • Weight: 10.12 lbs.


Many reviewers liked the LSR305's deep and well defined sound, along with its extended low frequency. Others thought that the upper register was smooth and precise, which gives it a well rounded and balanced sound.


There are some that comment on the speaker's subtly weaker midrange, but mainly when comparing the LSR305 with more expensive units.


The JBL LSR305 is easily the best bang per buck studio monitor in this list, and is highly recommended if you can find a pair available to buy, otherwise the next best alternative is the newer JBL 305P MkII which, at the time of publication, was widely available from most good music gear retailers.


Hello, excellent your site. I

Hello, excellent your site. I think you should educate people between equipment from real manufacturers (those who produce their loudspeakers) and equipment from assemblers (those who don't make their loudspeakers). Indeed, with real integrated manufacturers like JBL or RCF, there is the certainty of obtaining very quickly and for many years the equipment to be renewed following a breakage or seniority. More than 80% of brands only do assembly.
