#307 1980’s JBL MI Series 15A
15” Speaker Ferrite Magnet
8 Ohm 150 Watts
Musical Instrument Speaker
Made in USA
This speaker was removed from a JBL MI Series PA cabinet that I have yet to list. This speaker has been used very lightly as the cabinet was bought new and the speaker is very clean. There is no coil rub or rips in the cone.
This speaker is designed to handle high power amplifiers and produce clean sound without breaking up or producing distortion which makes it excellent for bass or vocal reproduction, much less clear and clean sound for guitar and keyboards. This speaker is also extremely efficient and requires very little power to operate. The SPL (Sound Pressure Level) is much greater than conventional speakers due to it's very high power magnet structure and heat resistant edge-wound voice coil.
We use a Klein multimeter to show conductance on the voice coil integrity.

A careful evaluation of the Ml Series proves they give you a lot more. The frames are die cast... not cheap stamped baskets. A die cast frame provides a better heat-sink allowing greater power handling and because a die cast frame can’t flex, it reduces resonances from the frame.
The voice coils are fabricated from special wire that has been milled into a flat ribbon. Flat wire can be wound more tightly than round wire, putting more conductor (wire) in the gap. The design is more efficient and more rugged.
The voice coils are precision flat wound, in four layers with staggered seams. This construction is physically very strong and resists deformation from heat. The result is greater efficiency and increased power handling.
The Ml Series loudspeakers feature JBL Symmetrical Field Geometry (SFG) magnetic structure, a design that contributes to the clean sound. Typical magnetic structures, with non- symmetrical magnetic fields, add significant amounts of distortion because of the nonlinear pull such a field exerts on the voice coil.

If you do not, the speaker cones could shred and / or the voice coils could burn. If you try to run these speakers with too much power / volume we cannot guarantee that they will last. These speakers range in age and have not been used for a few decades. The cones are original if stated and are VERY FRAGILE.
