Original and Replacement Drivers for VMPS Speakers
This is a repository of information about the the drivers used in VMPS, both as original parts and as replacements. This is vital information for those who wish to repair and refurbish their VMPS speakers, so I ask that anyone with information to please post it here.
I am seeding it with some information. If you have information, please share it and use the format shown in the example below:

This is is the model that Morel identifies as a replacement for the MDT-30.Replace the items shown in
maroon with the information for the driver you are identifying.
Please note that this thread is not a place to ask questions or post items for sale. Notes:
- Even if a driver was used in a particular VMPS model, it does not mean that all instances of that model used that driver.
- VMPS (Brian) made changes and improvements, often incorporating different drivers through the lifetime of a particular speaker.
- Some drivers were sold as optional upgrades in some models.
- Where the VMPS model is not shown, it is known that Brian Cheney ordered the driver, but there is not a determination of where it was used
- "Certainty" is somewhat subjective and a percentage. If you are truly sure, and can see the model number on the driver, then it's 100%. "Kind of looks like it" is below 50%. Since people will make purchase decisions based on this information, try to give a fair estimate.

Driver: Goldwood GW-15PC-8 15" Heavy Duty Woofer 8 Ohm
Source/Part Number: Parts Express / 290-338
Used in VMPS Models: Super Tower/R
Replacement or Original Driver: Replacement
Certainty: 99%
Notes: Although specified and supplied by Brian Cheney, with passive radiators tuned by Brian for these woofers, I find that the extreme low bass is overpowering. The original drivers performed much better.
Further tuning of the passive subwoofer might be able to tame these drivers.
