A long time ago someone donated a plate reverb to a studio I work at...it's a EMT plate but it has Ecoplate electronics. The drivers are broken and there's no remote so it needs a lot.
I ordered some 9K piezo pickups from DigiKey but was wondering what to use for drivers. Parts Express sells these "exciters" but I think they are meant to clamp on a service and that might add too much mass to the plate. Or couldn't you take apart a woofer and use its driver and mount it to the rails in the plate?
Interested in hearing some options to get this guy working AND sounding good.

The only dude I know servicing a studio with an EMT is Greg Norman @ Electrical Audio. You can post on the Tech Journal he keeps on the Electrical Audio BBS or fire him an email and I'm sure he'd get back to you.

I'm looking to build a plate reverb so a driver is also on my list. I agree about not adding too much mass to the plate so unless there is a ready made EMT style driver available off the shelf modding a speaker may be the only option. Most DIY plates I've seen tend to use a driver mounted directly on the plate. |

Here is the web site www.soliddrive.comThere is a big thread on GS where somebody used one on a DIY plate ! I have a permanent demo on one of my walls for when my neighbor gets annoying! |

The issue with these style of drivers is their mass and that they are directly affixed to the medium they are driving. This maybe fine if you want to turn a wall in your house into a speaker but not so good for driving a plate reverb. As the OP alluded to: For those attempting to get close to the orginal EMT sound these type of drivers are going to add a fair bit of mass to the plate right at the point of excitation and will change how the plate reacts compared to the original design. Here's an EMT 140 plate reverb with the driver magnet assembly removed. You can see the coil assembly fixed to the plate protruding through the centre of the driver mounting bracket. The driver magnet is mounted on the frame, not the plate itself, and this just leaves the coil which is fixed to the plate and is much lower in mass than the driver magnet assembly.  |
