    Room Acoustics Terminology Standing Waves Sound coming from a speaker bounces around in a room until a pattern emerges—this is called a standing wave. Typically, this is only a problem with frequencies below 100Hz. When this happens different parts of your room experience either an excess or a lack of bass.

    ™ (see figure 17), included with your Depth. With the use of these spikes, the Depth subwoofer 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.

    Home theater is a complex purchase and we recommend that you consult your local MartinLogan dealer, who is well versed in this subject. Each piece of a surround system can be purchased sepa- rately.

  • Page 17: Depth Advantages

    Low-Pass Filters Maximize Blending The Depth's low-pass filters achieve extremely precise crossover points in both amplitude and time domain resulting in seam-less blending with both MartinLogan and non-MartinLogan products. By tailoring custom filters to the main speaker roll-off characteristics, minimum group delay results in cohesive integration and musical results.

    Is there likely to be any interaction between my sub- woofer and the television in my Audio/Video system? Yes. The Depth subwoofer doesn’t use shielded drivers. Since the drivers are arrayed to balance the reactive force of the woofers, their magnetic fields are also balanced. We recommend 3 feet between the Depth subwoofer and video components that are susceptible to magnetic fields.
