Product Details

Bohlender Graebener RD48 Planar Transducer

The Bohlender Graebener RD48 was specifically designed as a replacement for the Carver line-source transducer. They share the same electrical and acoustical characteristics, which ensures that the same performance and sound quality are maintained. The original Carver transducer was used in some of the Carver Amazing Loudspeaker Series as well as in several Genesis Loudspeakers models. Keep in mind that if you have a Carver element which has blown or otherwise catastrophically failed, there is a good chance the RD48 will suffer the same fate if no changes are made to the system. Be sure to evaluate amplifiers, crossovers, and connections before you install the new RD48! Also note that on some Carver speakers, a small spacer is needed between the mounting flange and the baffle, allowing the front face of the driver to sit flush with the surface.

Specifications: • Power handling: 70 watts RMS/270 watts max • Nominal impedance: 4 ohms • Re: 4.0 ohms • Frequency range: 150-18,500 Hz • SPL: 88 dB 1W/1m • Net weight: 25.2 lbs. • Dimensions: 48" L x 6" W x 1-1/2" D.

Rated 5 out of 5 by from Excellent product..I got this as a replacement for my old Carver ALS-III transducer. Beautiful clean sound. But when you hear this, you pretty much have to get two... :-)PS: Taking apart the old Carver transducers is also a lot of fun...

Rated 5 out of 5 by from rd48just want to thank the sales dept,dealing with Partsexpress for years! they will not let you down.this driver is killer in so many ways you can build a flag ship speaker that will take you to the event.compliment it with a good ribbon around 2.5 to 4k and a good fast mid bass drivers around 200 to 400hz passive and you are good to go.note a lot of people run active not an option for me i run tube amps.if you you can build a passive crossover you dont have to go active as others say. after all its just a driver and one of the best.also to get the best sound go dipole get out box you will never go back.

Bohlender Graebener RD48 Planar Transducer

Is this an exact replacement for the Genesis 350 midrange?

I have a pair of Genesis 350se loudspeakers, with the BG48 midrange speakers. One of these has some ripples and possible damage, and I am thinking of replacing both. Is this an exact replacement, or does Genesis make some special modifications to the BG 48? Thanks
Asked by: Stan
The Bohlender Graebener RD48 Planar Transducer is not a direct equal replacement for the ribbons in your Genesis 350 speakers and even farther from a replacement if you have 350SE's.It is an excellant replacement for the Carver ribbon. When you reach this level, they all sound good, but the Genesis is flatter in actual responce and almost transparent in coloration.If you wish to exactly duplicate the performance of new then these will miss the target, however if you wish to improve the sound of ribbons that are damaged and get to an impressive sound at less than half the cost of OEM ribbons, then this would be a good choice. It really depends on your budget and drsired outcome.You should understand that if you did an A /B comparison of new Genesis 350's to a pair with replaced Bohlender Graebener RD48 Planar Transducers you will notice a difference. If you didn't have a pair to compare against, you most likely would not find a difference. It is subjective at this level.Good Luck

Is this an exact replacement for the Genesis 201 midrange ribbon?

Asked by: chien
Unfortunately only Genesis will be able to answer that. Companies often will take a driver like this and make minor changes to it for their own products and we have no way of knowing what those changes are.
