zZounds Gear Experts Say...
5.25 in. woofer. 1 in. Titanium composite diaphragm tweeter.
Overview
The LSR25P Studio Monitor combines JBL's latest in transducer and system technology and incorporates many of the design philosophies of their LSR Studio Monitor Systems. Scaled to provide an extremely accurate reference for workstations, edit suites and small control rooms, the LSR25P.
Features:
5.25 in. woofer
1 in. Titanium composite diaphragm tweeter
Elliptical Oblate Spheroidal (EOS) Waveguide with 50 x 100 degrees dispersion
Bi-amplified design with 100 watts of low frequency power and 50 watts of high frequency power
Front Panel Volume and Power Controls
Integrated mounting points for horizontal or vertical orientation
Shielded for use next to Video Monitors
Built-in high pass for use with optional subwoofer
The LSR Philosophy
The Linear Spatial Reference (LSR) philosophy is based on a set of design goals that carefully control the overall performance of the system in a variety of acoustic spaces. Instead of focusing on a simple measure such as on axis frequency response, LSR designs require much better control over dispersion via transducer selection and crossover frequency design. Critical decisions of image placement, EQ, balance and timbre are typically made within +/-15 degrees vertically and +/-30 degrees horizontally. This workspace is where the engineer, producer and artist make critical mixing decisions and this is the area that LSR is optimized for superb in room response. By incorporating LSR into the system design requirements,… read more placement rules are relaxed, a more stable stereo image is maintained and off axis coloration is minimized. read less

"They are great little speakers."
Verified Customer
zZounds has verified that this reviewer made a purchase from us.
I have used these a lot but I do not trust them like I did my old speakers. They sound great. I mean amazing for little speakers. They have great bass response. I am just afraid there is no apparent quirk that I can work with. Sounds crazy but I think I am supposed to do more work to test my mix.
Sound
They sound great and the music has been fairly portable without a lot of compensation.
Features
They sound good. They have a notched volume knob that help if you need to turn down from the speakers.
Quality
I have had them for several years and never had a problem.
Value
I think they are solid and well made and sound good
Manufacturer Support
No idea never needed any.
The Wow Factor
I want lots of things. I got this so I don't know
Musical Background:
20 years of playing and recording. Run a small studio as a sideline
Musical Style:
Rock, jazz and hard rock almost heavy.
