Some 20+ odd years ago I built a FS using Targa woofers that were 8ohms.
They sounded and still sound very very nice.
And they're very tough as well.
They're one of my favorite speakers.
I'm thinking of an MTM with side firing 10" sub and planned to use TARGA sub drivers.
I called Dai-Ichi Mega, they don't have them anymore
They have a very nice 10" sub but its 4ohms
Wish they still have those 8ohm Targa Sub drivers.
(BTW, the lady at the other end of the line was very nice to talk to...)
