Put Your Speakers on a Solid Foundation
Put your speakers on a solid foundation with MartinLogan MiniETC Energy Transfer Coupler Spikes. These hefty hunks of metal install in minutes with absolutely no tools required. Once you've installed them, you will immediately notice tighter, better defined bass and cleaner, more dynamic highs, along with improved imaging and focus.
Perhaps the best feature of MiniETC spikes is just how easy they are to install and adjust. All you have to do is screw them in, finger-tighten the jam nut, and then raise or lower the speaker by rotating the center spike.
MiniETC spikes have a standard 1/4-20 thread. Choose package of two spikes or package of eight spikes. |
