harsh, lacking depth. Most experts recommend leaving the equipment on to avoid the damage associated with cold
9.Bloated Image or Poor Focus. Slap echo from hard walls, or too much rear Ambience.
10.Room Effects: Boomy Bass, Harsh Highs. Not many audiophiles realize how important their room acoustics are to the overall soundfield. No matter how good the speaker system and driving electronics, the room will have great influence over the final sound, whether for better or worse! Harsh highs can be created by echoes reflected from large wall surfaces with unbroken surfaces. If you can hear any echo when clapping your hands, you will need to use some room treatment products.
11.Lack of Bass. Check the wiring to the woofer modules and make sure they are in phase. Rooms can add or subtract bass response, but correct tuning and placement can ameliorate these problems. If your electronics or cables are really bright, you may feel that there is more treble than bass. Try substituting different electronics or cables and recheck your room placement.
ROOM ACOUSTICS
Many books have been written about room acoustics, and there is not enough space in this manual to give detailed information on how to do it right. However, the general rule is to use 50% absorptive/50% reflective ratios when covering the room’s surfaces, such as carpeting, drapes, stuffed furniture, bookshelves filled with books, records, etc. It is helpful to damp the first reflection points, which are the boundary surfaces halfway between the listener and the speaker cabinets. This includes the ceiling, walls, and floor. Hard plaster ceilings will reflect treble energy back down towards the listener, and should be treated with acoustic tiles (the soft and porous type) or damping pads made from foam or fiberglass. The walls can have a decorator rug, drapes, or diffusers at the first reflection point, and the floor can use carpeting. We have used plants and trees to diffuse the echo in our very large sound room, and found that this works better than simply absorbing the high frequency reverberation. Some of these diffusion devices are made by Acoustic Sciences Corporation (ASC), Echo Busters and RPG, along with others. Tube Traps by ASC are placed in room corners and will absorb bass boom and flutter echo in the mid/treble region. Michael Green offers Corner Tunes, which are placed in the upper corner joints of the wall/ceiling junction. Call your dealer for more info.
