Post Subject: How to use the TAD 1201?Posted by Romy the Cat on: 1/3/2008

Greg, I see a regions of concerns that you might contemplate.

TAD 1201 might be good driver but how useable would be the 200/300-800/1000 range? Let pretend that you end up with 250Hz, then what next? You will introduce a bottom octave section but to cover a range from the very begging to 250Hz is practically impossible with one driver. To reproduce 30Hz and 250Hz is require VERY different type of drivers otherwise it will be a compromise in one of other extremes.  In your room of 21’ by 25’ I would like to see driver with Fs of 20Hz in 25-30 enclosure – those types of the drivers will never go up to 250Hz. In a contrary if you go for 35Hz bass drivers (typical JBL) in 45Hz enclosure then in your room you will not get the lowest octave. BTW, did you consider to EQ down the TAD 1201 with a horn? It is 52 Hz driver and in a horn you might easily to push the driver to down to 100Hz or even lower. Do not forget that horn wills EQ the driver + it will have add a few dB at LF that will minimize the excursion…. They are 12-inchers so, 7-8” throe would do most likely…  Though I have to warn you that I am generally horns-biased… What I mean was that if you already have 4 of those 1201 drivers (you intended to use then in MTM configuration) and if you found them “amazing” then it might be a plausible direction:

I would encourage you to think about the “MF Island” separately and then just add a complimentary LF sections - it might help you to deal with the issues of your room.
