5" near-field studio monitor, ideal for home and project studios.
The LSR305, part of JBL’s 3 Series studio monitors, is a 5” powered studio monitor delivering professional performance at an affordable price points. 3 Series Powered Studio Monitors are first to incorporate JBL’s exciting new technology, the Image Control Waveguide. In conjunction with 3 Series high-performance transducers and system components, the Image Control Waveguide lets you hear detail and depth in recordings as you've never heard before.
The LSR305’s 5” long-throw woofer and its 1” damped woven composite Neodymium tweeter are designed from the ground up to reproduce the powerful transients and micro dynamics of your mix. These drivers deliver impressive deep bass and smooth high frequency response beyond the range of human hearing.
JBL’s Patented Slip Stream™ low frequency port design works in concert with the woofer to produce deep bass response at all playback levels. The double-flared shape of the port is precisely engineered for greater low-frequency extension and reduced turbulence.
Big Power, Big Sound
3 Series efficient Class D Amplifiers provide abundant power to deliver the output and dynamic headroom needed for the most demanding production styles
Professional Balanced Inputs
Balanced XLR and 1/4” (6 mm) TRS inputs give you the options you need to connect your 3 Series to any signal source while maintaining professional signal quality.
Selectable Input Sensitivity
The -10 dB/+4 dB sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect the 3 Series to high output professional gear without any danger of input overload.
LF Trim and HF Trim “TRIM” switches for both the Low and High Frequencies give you excellent control over the 3 Series sound in “your” room. Use these to fine-tune the amount of bass and treble you hear to compensate for room acoustics, program material and your personal taste.
JBL Professional Reliability
Prior to becoming a production-ready design, each 3 Series model is subjected to JBL’s tough 100-hour power test, in which the speaker is required to play continually at full output for 100 hours without failure. This demanding test ensures your 3 Series speakers will deliver years of reliable performance.
JBL LSR Design - Your Music Needs a Point of Reference
While most manufacturers take only a single on axis measurement of the speaker’s performance, this doesn’t tell how it will sound in your room. JBL’s LSR Linear Spatial Reference design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker that “sounds right” in any working space. With LSR design, 3 Series Studio Monitors deliver superior accuracy regardless of the size and shape of your room, so your mixes “hit their mark” when heard on any playback system.

Comments about JBL LSR305 5" Powered Studio Monitor:
Just got the LSR305's and wrote a quick review in the review section. Figured some of you ne'er-do-wells are too lazy to hunt it down, so here it is;
I came reeeeel close to getting the Equator five inchers with all the hubba-hubba this forum gives those things, then suddenly last week someone started screeching ecstatic about some new JBL's. Well, HEY! I'm a sucker for a good screech, and since the JBL's were cheaper than the Equators, excelsior!
So here they are. They are smaller than I thought (7 1/4 " W, 11 3/4" H, 9 1/4" D), which is fine. Actually, smaller than the Tascam VL-X5 pair these will replace. And on top of that, no real manual, just a quick start guide (yeah, I know - you don't NEED a manual for monitors, but I like to read).
At first they confused me. I've been using the Mackie's for about four years now and they always sounded a little congested to me. Sure, they have some bottom, but the highs were always kinda eh and well, I could get decent mixes out of them, but... time for something new.
The reason the JBL's confused me was because they first sounded REEELY piercing on the top end and WIDE. Much wider than the Mackies. As they settled in a bit, the piercing top subsided. I put on the Beach Boys' SMiLE album, since it has such a wide range of instruments and was recorded so well (at least for its time) and A/B'd for an hour.
No question - even though the Mackies' woofers are six inches and the JBLs are five, the JBL has more bass response AND it's sharper. SMiLE uses lots of contrabass, which sort of disappears in the Mackies. They are there in the JBLs - there's more pluck - more definition to the lower end.
There is also more definition in the upper frequencies - maybe too much. I made sure the HF switch on the back wasn't flipped to +2dB. I started thinking these things may have a built-in "smiley curve" eq. So when I switched back to the Mackies and noticed they were suddenly very two-dimensional. Sort of like that same 2-D sound you get using cheap console preamps. Don't get me wrong - they're very useable and can get the mix done - however the old cliche "lifting a veil off the sound" is true here when switching back to the JBLs. While the Mackies are supposed to be ruler-flat and really emphasize the midrange (at least mine do), that midrange is very *flat* sounding. Things jump out at you on the JBLs - the extra vocal bits from Heroes and Villains really show they were recorded on different days when listening on the JBLs; this should be a great advantage when blending tracks together.
The JBLs at first give the appearance of being top-driven and bottom spunky; once you settle in with them, you'll notice a very wide, clear midrange - you can step into these monitors. You can clearly hear the rooms the separate SMiLE bits were recorded in as well as the different applications of plate verb Brian was using. My apartment requires me to mix at lower levels (sometimes I briefly turn up loud just so my neighbors know I CAN) and even at the lowest levels, the JBLs translate clarity and 3-D-ishnessicity. Are they as round as their 8 inch big brothers? Of course not - however in a small studio setting (mine is 12' X 15') they get as low as you need, provided you have at least SOME room treatment. If you're doing a bunch of sub-bass work, you'll probably feel better getting a subwoofer - the lows are THERE, but they won't rattle your cattle. They're five inch woofers ferpetesake! Get a grip!
Considering that I've been using the Mackies for 4 years and the JBLs for ONE HOUR, I have to say I'm really impressed with the JBLs. Once they break in, I imagine that high end shrillness I initially noted (which is already loosening up) will mellow nicely. I probably should have gotten the 8 inch woofers in retrospect, but for my room, these are Swellsville. If you've been thinking about new 5 inch monitors, these are exemplary.
