SKU: 6MB400 Categories: , Tag:



The 6MB400 was designed to provide outstanding durability as well as a smooth punch of mid bass. This 6.5″ professional loudspeaker midbass is purpose-built to cover the critical frequency range in a three-way speaker setup, but also works great as a door speaker in car audio applications. The future is here! Smaller and more powerful mids.

  • A fast and tight midbass response along with a strong vocal response
  • Small profile capable of handling high power, smaller but yet powerful
  • Natural paper cone and double-roll surround for smooth response
  • Handles 400 Watts, guaranteeing endurance at loudest volumes
  • Impressive choice for high output home, car, and professional audio systems – 8 Ohm impedance

Built with many premium components to ensure absolute high sound fidelity, one of which is its compact push terminals, which connect to its silver tinsel lead wires attached to its high temperature CCAW voice coil.

Don’t underestimate its compact motor design! Featuring the latest technology we can increase tremendously the magnet field without huge magnet, making this midbass one of its kinda, small profile capable of handling high power!


Featuring a naturally damp paper cone this professional speaker is able to cover a wide range of frequencies from 95 Hz to 7,500 Hz in three-way systems.

Developed to perform well in tight enclosures, its double roll surround keeps cone travel linear at high excursion. The right combination of cone and suspension gives this speaker an excellent human vocal reproduction with dynamic midbass sound.

6MB400 Frequency Response
*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
