To eliminate this unwanted effect, you will need to determine whether the room’s reflections are at fault, or whether you are not in the “sweet spot.” REAR AMBIENCE DRIVER ADJUSTMENTSTANDING WAVE PHENOMENA GENERAL TUNING INFORMATIONBASS RESPONSE TUNING TOO MUCH BASS OVERALL THEORY OF RECIPROCITY REGARDING BASS RESPONSElengths that the waves take before arriving at the listening position. Although the first arriving bass wave will have flat frequency response, fractions of a second later the same waves have bounced off of the front wall, rear wall, side walls, and the floor. These reflections both reinforce and cancel the original direct wave, depending on the wave length vs. the path length. If the path length is an even multiple of the direct wave at any one given frequency, the reflection will reinforce the first wave since it will be mathematically additive and will cause a peak in the response at this frequency. However, if the path length is such that the reflected wave is out of phase with the main wave, there will be a cancellation in the frequency response. Researchers have found that the dips and peaks in the response can be very powerful, with 18dB variances across the bass range! Note that this effect occurs with ANY speaker design no speaker system can overcome the law of physics LACK OF APPARENT BASS BASS RESPONSE TUNING FOR TUBE AMPLIFIERSANCILLARY EQUIPMENT metal film resistor to equalize the sensitivity of the louder speaker in order to make a fair test. Here at the factory lab, we have used several brands of electrostatic and ribbon speakers for comparison and have been consistently amazed at the results we are achieving with dynamic cone drivers TROUBLE SHOOTINGmost wear to the electronic components in an amplifier results from the inrush of current from the wall into a cold part. Once the unit is left on, the voltages and temperatures stabilize, resulting in better sound and component life. The electric bill will not reflect a huge price difference, as electronics at idle do not use much electricity other than Class A amplifiers and tube amps CARE FOR THE FINISH
