Hey Mike.
I try to keep whatever information of a product
I own. In the event, the manufacter no longer
offers any documentaion of the item, I don't
need to google the web for answers. I bought
the last 200 watt EVM 15B from a store's
showcase window 9 years ago. As with all Mom
& Pop stores, they keep the original box, &
paperwork.
Hanging around with alot of Vintage Home
Audiophiles in the late 90's, I found out
only 15B recones were being made. So, if
you had the 15L reconed, it would be a 15B
I figure Sumsound is going by TL606 being
used, in the response graphs on the 15B.
Looking at my sheet, its the only box used
unlike the EVX 180 B that offers 6, 8, & 10
cubic feet enclosures.
Yeah. Twelves have become the norm for hornloaded
subs these days. I remember alot of horn designers
always saying xmax, was the limiting factor, why
they needed to use fifteens & eighteens.
Sumsound,
It was only until I seen your post in regards
to the BT 7 I realized, you weren't using EVM
for subs. If you want something ultra low, and,
compact, why don't you checkout the Contrabass.
Usable to 14 Hertz. I think it was servojohn,
who said he was using a pair for his bass.
Best Regards,
