Beston RT002a Replacements

[Dwvsplat]

I have a pro audio problem. I have some speakers in a church that keep blowing the ribbon drivers (Beston RT002a). This is a line array system (TVI BT-600) each cab. has 2= 4" mid drivers and 1 beston ribbon. I have compressors and limiters on the system (also it has built in limiting through the DSP, on the built in amp), but the bestons keep blowing after a while. Is there a good horn and driver that will be an exact fit, and can handle more power? The cabs are routered out so the bestons are recessed.

Re: Beston RT002a Replacements

The Beston ribbon isn't exactly a PA driver, and they recommend at least a 3rd order filter at 2500Hz. I don't know what you'd use as a drop-in for that form factor other than a super expensive Beyma TPL-150H. You could always replace the Beston with a compression driver which will increase power handling exponentially.

What compression driver would you recommend for this project? The original ribbons were a metal frame, where the bestons are plastic, but there was no name on them, and the bestons seem to perform as well as the originals.

Raise the crossover frequency a bit. Make sure it is 4th order or higher.

The D-Fend speaker protection system sold by Eminence was originally developed by SLS to protect their planar ribbon tweeters. It goes between the amp and the speaker and dynamically increases the impedance when the power limit is reached to prevent blown drivers. Planar ribbon drivers are not robust, and TVI boxes are not regarded as good designs, so you have an uphill fight to keep these ribbons from blowing.
