16 Room Acoustics
After living and experimenting with your Dynamo, 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
Dynamo will become more firmly planted on the floor
and, consequently, 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
1
/4-inch thread insert that may be found on
your other audio equipment (racks, speakers, etc).
Spike Installation Instructions:
1 Carefully lay the Dynamo on its side to gain access to
the bottom.
2 Remove existing feet or spikes. Thread new spikes into
holes and screw them in all of the way.
3 Tighten jam nut snugly by hand. Do not over tighten
the nut.
4 Right the subwoofer.
Caution: Make sure your hands and any cabling are
clear of the spikes. Do not slide the subwoofer as spikes
are sharp and can damage your floor or carpet.
5 Adjust to level by rotating spikes. Tighten the jam nut
securely when satisfied that the subwoofer is level.
Caution: Walking the Dynamo may result in a broken spike.
