After living and experimenting with your Abyss, you may
want to use Mini ETC™(Energy Transfer Coupler) Spikes
(see figure 19), available from the Xtatic shop at www .
martinlogan .com . With the use of these spikes, the Abyss
will become more firmly planted on the floor and, conse-
quently, bass will tighten . It is best not to implement the
spikes, however, until you are secure in the positioning,
as the spikes can damage the floor if the subwoofer is
moved . MartinLogan Mini ETC spikes will fit any common

-inch thread insert that may be found on your other
audio equipment (racks, speakers, etc) .
