Having gradually dialed in the x-o on these odd looking speakers, I can say that Danny's M130-16 is a very nice driver to work with and to listen to.
The drivers are GR M130-16 mids an Seas 27TDFC tweeter running in a framed open back, and Jaycar 10" bass unit vented out the base, all lovingly combined with a linked series x-o. Sounding VERY nice !!!
In this pic , they are lying on the back about to have the drivers attached.

Danny, please don't delete this..
