JBL LSR308: Pro-Level Monitor Speakers for Your Home Studio

With the JBL LSR308 powered studio monitors, JBL has made their patent-pending Image Control Waveguide technology available in an amazingly affordable model! The LSR308 is a bi-amplified monitor with a magnetically shielded 8" woofer and a 1" soft-dome tweeter outfitted with the Image Control Waveguide -- a means of sound dispersement that promises an incredibly wide sweet spot in any room, originally designed for the JBL flagship M2 Master Reference monitors at $20,000 a pair. The Image Control Waveguide controls sound in the vertical and horizontal planes, allowing the engineer or musician to move around freely in front of the monitors without hearing changes in frequency response, even allowing you to accurately discern mic placement. With the LSR308, JBL is bringing this technology, previously reserved only for high-end engineers, to the masses.

Check out our exclusive demo of the JBL LSR308 Powered Studio Monitor:


Built for Wide Frequency Response at Any Volume

When you're playing back a mix at low volumes, many monitors lose bass information in the mix, losing accuracy and becoming unusable. JBL has outfitted the LSR308 monitor with their patented slip stream low-frequency port design, which works with the woofer to deliver great bass response, even if you're listening at low levels, using the double-flared shape of the port on the rear of the monitor. The LSR308 uses Class D amplifiers to power the speakers with ample headroom, including an input sensitivity switch on the back of the monitor so you can be sure that you'll never overload it or head into distorted territory.

Options That Match Your Studio

The JBL LSR308 is outfitted with balanced XLR and 1/4" TRS inputs, so you'll never run into a situation where these monitors won't fit. The back panel also features trim switches for the high- and low-frequency response, meaning you can tune them specifically to your room, which makes them some of the most adaptable monitors on the market, fit for any room, from bedroom studios to full-blown professional control rooms.

JBL Means Reliability

Before shipping out any set of LSR308 monitors, JBL runs them through a 100 hour power test, where they must perform at full output for 100 hours without failing. They also test their monitors with LSR -- that is, Linear Spatial Reference -- criteria, taking 72 measurements that make sure these monitors sound right in any room, no matter what. The LSR308 monitors truly have professional standard features with an affordable pricetag that is sweet enough for bedroom recordists.

Features:

- JBL's Image Control Waveguide, a unique design ensuring accurate sound imaging in any room
- Bi-amplified 112-watt monitor, with a 56-watt Class D amplifier behind behind the 8" woofer, and a 56-watt amplifier behind the 1" soft-dome tweeter

- Patented JBL slip stream low-frequency port design

JBL LSR308 Powered Studio Monitor

The JBL LSR308 8" bi-amplified powered studio monitors are the first affordable studio monitors with JBL's patent-pending Image Control Waveguide, for remarkable performance over a wide listening space in any room. The difference is indisputable. With the Image Control Waveguide, 3 Series delivers incredible imaging, with an expansive soundstage and solid phantom center. Increased detail means you'll hear micro-dynamics in reverb decay -- and hear mic placement! The LSR305's broad sweet spot let you hear the same response across a large space in any room.

Image Control Waveguide

The Image Control Waveguide was developed for JBL's flagship monitor. With the introduction of the JBL 3 Series, is now included for the first time in an affordable, compact reference monitor. The patent-pending design of the Image Control Waveguide precisely controls the sound emanating from the speaker in the vertical and horizontal planes ensuring the presentation at the listening position is neutral and accurate.

JBL Transducers: Legendary for their Performance

The 3 Series long-throw woofer and its 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

This port 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

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 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.

Features:

- Bi-amplified 112-watt studio monitor
- Class D 56-Watt RMS amplifier for LF, and 56-Watt RMS amplifier for HF
- Magnetically-shielded 8" woofer
- 1" soft-dome tweeter with Image Control Waveguide
- Balanced XLR and 1/4" TRS inputs with detented level control
- HF and LF trim controls
- Includes US power cord
Customer Reviews
4.5 out of 5 (8 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Great for playback, and for live monitoring."
Overall: I purchased a pair, which saved me $125.00 from zZounds, of JBL LSR308 Powered Studio Monitors. I use them as monitors for studio live play, for practice, and for recording playback. I have a Taylor 416ce with expression electronics, the reproduction through these 308’s is crisp, clear and rich bass. The reproduction is better than I expected. I was considering an acoustic amplifier, I am holding off for a while because these monitors are getting the job done for what I need right now. They sound just as good, better in my opinion, as the Yamaha HS8’s for a lot less money. Can’t go wrong with these monitors. I haven't had any issues with the speakers, so I have no rating for JBL support.
Style of Music: soft rock, rock, alternative, rockabilly, blues, country, folk, ect...

zZounds has verified that this customer bought this product from us. "Outstanding Sound at a Great Price"
Overall: I recently upgraded from 5" M-Audio StudioPhile Monitors to these 8" JBLs. Those old ones were actually pretty nice for low-budget monitors, but I just wasn't hearing the crisp highs I needed, or feeling enough thump from the bass frequencies. These JBLs answered all of those concerns. Rich, full bass, clean, crisp highs, and everything in between. I am extremely happy with these monitors, ESPECIALLY at this price. I was lucky enough to score them from ZZOUNDS for only $199 each on sale, and was psyched about that, but they are definitely worth the regular price of $249 each IMO. JBL is a trusted brand, they sound great and look awesome. They are quite large, and fill up my desk, but the tweeter is almost perfectly at ear-level now with only Auralex Mo-Pads underneath the monitors- no stands. I mostly compose music intended for Movie Trailers. A lot of it is that EPIC style that is very common these days- heavy guitars and percussion with orchestral sounds, too. These JBLs are handling these sounds beautifully. I'm giving them 5 stars for Manufacturer Support, although I have not needed their assistance. I am assuming that a company like JBL would provide good support, but hopefully I won't need to find out. I HIGHLY RECOMMEND THESE.
Style of Music: Decades of Punk and Rock Pro Band Experience on Guitar and Bass. Currently semi-professionally composing "Epic" and other st
