Features
PRV Audio’s 6MB550FT-4 6.5″ Forte Series midbass was specially tailored to give you more Xmax and less distortion on mid low midbass 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-4 one impressive driver. With 94 dB efficiency and 275 watts power handling this midbass 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 550 watts RMS without issue.
This midbass 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.

*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 provide 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.

Customer Reviews
Great sound. I replaced some other brands with these and what a difference! I'll be ordering a pair of super tweets to finish off my Hayabusa install.
Great output and punch!! Does well crossed-over or allowed to naturally rolled-off... running mine active with around 200+ watts. They seem to handle the power being high-pass crossed-over at 12db 100hz. As far as PA style speakers go these are very good. They sound smooth paired with the PRV Audio TW100SD super tweeters and combined create a solid component set.
The best speaker 6.5" I've tried so far.
The best Prv.
Ive tried a handfull of speakers and these are by far the best they sound good they get extremely loud and i can set my crossover to 100hz (while every other speaker has to be set around 150hz for bass heavy songs) and play any song at full volume with about 200w per speaker i just wish they made a 2ohm version to squeeze a little more power out of my 1000w amp
