The 6MB250-NDY-4 offers smooth lower response through a punchy mid bass range and the frequency response that takes your applications smoothly through the 6,500 Hz range. The size and punch of this pro audio driver makes it perfect for a mid range driver in a 3 way loudspeaker cabinet or woofer in your studio monitor while offering outstanding mid to lower vocal support, and at less than 2 pounds it won’t add much to your cabinet weight or your car audio installs.

The 1.5″ voice coil, durable spider suspension and the woven surround all supported by the sturdy steel basket ensures its ability to withstand long hours of operation without compromising efficiency of the speaker. A thick, yet light rigid cone ensures accurate response and power handling.

Looking for car door speakers? This is a perfect light weigh option without the bulky magnet.

    all our speaker can be free air mounted, but you will lose power handling and a lot performance.

    we do recommended you to have some type of enclosure for it, so the speaker can have a load to it
