When using a pa ir of VA-X Subw oo fers in stereo. it is preferable to

Caut ion!
The VA-X Series Subwoofer amplifier is built into the subwoofer cabinet. Do not
pl ace the cabinet next to sources of heat such as furnace registers, etc. The
power cord should be routed in such a way that it will not be walked on , pinched,
or compressed.
Rega rdless of where you install your VA-X Su b woo fer, it must remain
in an up
ri ght position (passi ve r adiato r Facing dow n wa rd). Usi ng.
shippin g, or otherwi se sto ri ng the VA-X Su bwoo fer in any other posi-
t io n for an extended per iod of time m ay ca u se the passi ve r adiato r
suspension to perma nently

The VA -X Subwoofe r' s d ri ve r h as been magnetically sh ielded to
reduce magnetic emissio ns from its cabinet. However, this shielding

ay not be adeq ua te for all install atio ns. La rge-screen tel ev isi ons
are particula rl y sensitive to stray magnetic fields. If your tel ev ision
produces distort
