Nautilus 801 bass/room size amplifiers


Having a problem with standing waves in a 20L x 19W x 8 foot high room. bass guitar(guessing 100hz) on some lp's are boomy and lower bass(maybe 40hz)is rumbling. I'm biamping with 2 bryston 4bsst amps and may go to 2 14bsst. I cant afford more expensive amps!... I can increase my room length to 28 feet. I'm thinking this will make a huge difference... Any comments aire appreciated.

Square rooms are supposedly acoustically inferior to rectangular shaped rooms. I've only had rectangular rooms so it's hard to verify.

Nevertheless, it is my experience that speaker placement can go a very long way in minimizing the negative affects of a room's inherent acoustic deficiencies.

You might try moving the speakers out perhaps 8 ft or more from the wall behind them. This should help quite a bit if you've not tried this before.

At the same time, you might also consider placing the speakers no more than perhaps 4 or 5 ft from the side walls.

(all measurements from the front center of woofer).

From this starting point, listen for a day or so and then move the speakers around in 4 inch increments (front, back, sideways) attempting to locate the best bass compromise. With a little diligence, you hopefully will find a speaker location that smooths out the entire bass region at least to a much greater extent than what you previously had.

Afterwards, you might try moving the listening chair about to also help obtain the best sonics. Although speaker placement should have a far greater impact over chair placement.

In addition, you might want to ensure that:

1. you have good heavy carpeting/large rugs and pad installed.
2. All reflective surfaces are removed i.e. tables, floor lamps, leather furnishings, mirrors, glass pictures, etc..
