GS8ND2
8” Subwoofer/Woofer/Midbass
Is it a subwoofer? A woofer? A Midbass
driver? It’s all three.
Audiofrog’s all new GS8ND2 is deisgned as
a shallow mount subwoofer for use in
applications in which space is at a
premium. Many shallow mount subs are
designed to minimize mounting depth, but
compromise excursion capability in the
process. Often, the sealed box volume
requirements are too large to fit the appli-
cation.
At Audiofrog, we recognize that the appli-
cation for a shallow subwoofer is a small
sealed box. Small sealed boxes require
subwoofers with plenty of excursion poten-
tial. The GS8ND2 provides 10mm of linear
one-way excursion for great performance
in sealed boxes as small as a quarter cubic
foot. The GS8ND2 is also a stellar performer
in a vented box as small as a half cubic
foot.
For OE replacement applications, the
GS8ND2 is also a great choice for under-
seat enclosures in BMWs, Front-Bass
replacements in Mercedes Benz or in
factory-provided vented and sealed boxes
in the quarter panels of SUVs. The GS8ND2
will also work in an OE infinite baffle appli-
cation.
If you’re building a custom system in which
you need an 8” midbass or in which there’s
no room for a subwoofer and the front
speakers have to be full range, the GS8ND2
is a great choice.
How can one little woofer do all of this? It’s
been carefully designed and engineered.
A conventional overhung motor with plenty
of excursion ensures great performance in
a small sealed box. Carefully chosen free
air resonance (Fs) makes building a small
vented box with a reasonable port length
possible. The copper shorting ring reduces
distortion and extends the high frequeny
response for smooth and powerful midbass
up to 300Hz .
The GS8ND2 does what no other 8” can.
