The JBL LSR4326P is a robust (28 lbs.), biamplified, 2-way studio monitor speaker, housed in a sturdy, handsome cabinet with a dark graphite finish and a carefully damped and baffled interior. The 6.25" Neodymium woofer and Waveguide-controlled 1" silk dome tweeter are powered by 150 and 70 Watt amplifiers, respectively.
The LSR4326P features a uniquely ambitious front and rear panel set of tune and tone controls, that borders on the fanatical in sheer statistical density. We are now recording and mixing in some strange and wonderful places, and these places may foster and nurture the creative spirit, but for critical listening these places often need sound treatment, and it doesn't get done. And that is why JBL has stocked the LSR4326P with knobs,switches and a remote control - to help us get good mixes in poor acoustic environments.
Now, all of this compensation for room modes, nodes, and standing waves, in bright, boomy, dull, fluttery, boxy, cavernous rooms, and all the other environmental acoustic aberrations that can make mixing a sad experience, does not come cheaply. But, the LSR4326P is designed very much for an age where a lot of music is recorded outside of the "proper" recording studio, and this speaker provides a certain reassurance that no matter where, and how strange, the space you're working in really is, you can fix it in the mix.
