Acoustic treatment

Hi jtcf,

     I just came up with the acronym ABT (automatic bass trap) to avoid having to use its full name on my last post.  
     I restrained from stating it didn't work because I've never tried them and, therefore, I'm not qualified to have an opinion.  
     My opinion is that good bass response is very important but one of the most difficult qualities to achieve in a home audio system.  I actually consider my system as two systems:  a bass system and a midrange/treble and stereo imaging system.
    I also prefer a system focused on producing good bass than one trying to improve bass that's already been produced in the room.

Later,

In the case of the wretched CD there are two reason why bass response is really rather wimpy and apparently rolled off and otherwise unimpressive. It’s because of the two problems I have been pointing out of late regarding (1) scattered background laser light getting into the photodetector and (2) the fluttering, wobbly and vibratory nature of the CD itself that forces the laser servo mechanism such as it is to work overtime trying to keep the bloody laser on track. The geometry involved with how the laser reads the nanoscale data is extremely susceptible to vibration of the disc.

Geoffkait, just throw the CD's away and download all your music in MP3 files. That should be perfect for you. Your ear works just like any other microphone. It detects minute changes in pressure. In your case you might want to clean the wax out first. In the office we use a waterpick for that. 1 part hot water to 1 part  peroxide. Careful not to squirt your eye:)

Ya don’t get what I’m saying here. Look, it’s not rocket science. All you have to do, gentle readers, is compare the cassette version of almost any record with the CD version. Or the LP version. All will become clear.

@theaudiotweak , are the synergistic research acoustic art (bowls) similar to what you are talking about?  I experienced these firsthand and they definitely worked.  Crazy stuff...

@noble100 , do sba work better in treated rooms?
