Features

PRV Audio’s 6MB550FT 6.5″ Forte Series midbass was specially tailored to give you more Xmax and less distortion on mid low mid bass frequencies, with its Peak-to-Peak excursion going up to 14 mm (0.55″) this speaker can give a heck of a punch!

The tall 2″ voice coil ensures high heat dissipation and the necessary motor strength to deliver high sensitivity even on high power with the minimum distortion with recommended High Pass filter of 95Hz at 12 dB Octave.

All this attention to detail makes the 6MB550FT one impressive driver. With 94.5 dB efficiency and 550 watts power handling this mid bass is ideally used in stage monitor, auditorium, touring, and outdoor systems. The smooth response from 85 to 7,500 Hz makes it perfect for 2 or 3-way designs.

Highlights

Designed to handle low frequency at a high power output
Xmax 5.40 mm – 14 mm Peak-to-Peak excursion before damage
A huge magnet for increased efficiency and control
High power copper tinsel lead wire
Vented pole piece minimizes power compression and increases power handling
Rigid cast aluminum frame can withstand the use and abuse of pro and car audio
Natural paper cone and double-roll surround for smooth response

A rigid cast aluminum frame with spokes to minimize reflections back into the cone. To drive the voice coil, a large ferrite magnet is used with a very precise machined top and bottom plate.

The additional forced vent in the backplate for the coil allows this driver to handle up to 250 watts RMS without issue.

This mid bass will stand up to years of serious professional use!

Its special composed spider reduces distortion at a high excursion and double roll surround keep cone travel linear at high excursion, while its copper tinsel lead wire is capable of high current transfer makes this driver not only unique but gives all high-performance characteristics and high-quality components providing exceptional clarity, detail, and dynamics sound.

Its CCAW voice coil has 14.8 mm of winding wire, giving it an incredible 5.40 mm Xmax with capability of 14 mm Peak-to-Peak excursion before damage, which allows its cone to travel over 0.55″ giving a heck of punch.

Featuring a paper cone has a special high strength paper pulp composition designed to achieve the best possible linearity within the middle frequency range and a special cone treatment specifically dedicated to improving the dampening properties of the moving assembly, thus considerably improving the smooth frequency response.
