RE: I want to have quiet playback on 100db speakers

:)
Thank You for reminding me the basics. I actually know that the output tap on transformer is not equal to output impedance of an amp and how bass alignment of speaker ( damping) can affect amp-speaker interface. It can be ameliorated with port tuning and if necessary driver change . This particular cab does not strike me as under damped but my question regarding bass meant to be more general in nature. Of course I know that most people here don't use fostex although there is nothing wrong with it.(personally I disliked the ones I tried )I did not imply (or it was not my intention) that you're using monitors or petite amp , frankly I have no idea what you you or others use , however it is obvious from responses that getting a monumental bass is not priority or not even a consideration for most. It is hard to get any bass out of Altec 604 (515) no matter what cab and alignment you try . It is hard to get any bass out of K-horn . It is hard to impossible to get any true bass out of small amp (SE or PP) when you have 2x15" or more drivers unless they are sort of special design with high efficiency , very low fs, low power handling and soft suspension (do they exist?) You can theorize all you want, but at some point you have to sit down and listen and excuse me but it doesn't strike me that you had listen to a lot, (oh dear am I wrong again ;)
At the end , looking at the drivers used in cabs (TAD TL 1602 ) an their pro designation and 21hz fs and likely ~35hz tuning and rather over damped nature, Yes fairly small amp might provide some bass.
Best Regards, W
