Is there likely to be any interaction between my subwoofer and the CRT television in my Audio/ Video system?
Yes. The subwoofer doesn’t use a shielded driver. We recommend 3 feet between the subwoofer and video components that are sus- ceptible to magnetic fields. Modern flat screen televisions are not affected by the magnets in your subwoofer.
Will my electric bill go 'sky high' by leaving my subwoofer plugged in all the time?
No. The subwoofer, when the power switch is set to ‘Auto’ or ‘Standby’, will draw about 30 watts when idle.
Should I unplug my sub during a thunderstorm? Yes, or before. It's a good idea to disconnect all of your audio/ video components during stormy weather.
I disposed of my speaker’s original packaging. Can I buy new packaging for my speaker?
Yes, replacement packing is usually available for current and recent MartinLogan products. However, replacement packaging may sometimes be quite expensive and we encourage listeners to save their original packaging materials. MartinLogan cartons will collapse and flatten for easy storage. Foam and additional packing materials may be safely stowed in a large plastic bag.
