I have a few issues:
A I was just playing some Stereophile Editor's Choice test tracks and TelArc Surround Test CD stereo setup tracks on my stereo at home. What I tried was playing discreet decay frequencies from around (iirc) 2kHz down to 25Hz. I found that the response isn't smooth at all. For example, 40Hz would be massive, then there would be literally nothing on the 35Hz step, then some resonance at 32Hz. It happens higher up in the frequency range too. How do I smooth out the frequency response?
My uncle told me that there are three dimensions which should not be simple multiples of each other, otherwise some of the bass frequencies may be cancelled out: 1. height of speakers, 2. distance from back wall, 3. distance from side wall. In my case, the height of the speakers is almost exactly half the distance from the side wall on the LHS. Might this be the culprit?
B I played some wide-band discrete frequency tone sweeps through the stereo and apparently if the room was perfectly set up, the sound from all frequencies would only appear to be coming from a single point in between the speakers. What I found was that the image shifted from left to right depending on the frequency. Apparently, this is due to a poorly set up room. Solutions?
C Another thing I tried was to do continuous and discreet wide-band frequency pans, which is basically playing a single tone across the lateral aspect from left to right either continuously or discreetly. The width of the soundstage is massive with the actual sound appearing to come from outside the speakers both on the left and right hand side. I was impressed. However, I would like more soundstage depth and also for the speakers to acoustically disappear. How would I achieve this?
D I have floorstanding speakers where the bass drivers are mounted on either side of each other, close to the ground. Now my components are also placed on the ground, in between the speakers. This means that the right hand woofer of the LHS speaker and the left hand woofer of the RHS will sort of firing into the components. According to the official literature, the two woofers operate in a push-push configuration. Regardless of what that actually means (please enlighten me!), the two woofers have been designed to work together and any slight asymmetry in woofer load (due to the reflections off the components coming back to the drivers) is likely to affect overall performance. In which case, would it be better to put the components elsewhere?
Last but not least, E The overall sound is slightly on the warm side. Are there any tricks which would slightly boost the highs? Perhaps moving the speakers slightly further from the back walls would result in less room reinforcement of the bass frequencies. My uncle suggested adding power-related upgrades. Currently, there is no power-related enhancements and I was told that changing the power chords and adding some degree of power filtering would possibly enhance the highs a little. Would it be better to go for power regeneration instead?
Thanks in advance. After yesterdays listening session, I discovered that there is still a lot of work to be done
