i want to try to build some tqwtl or a horn of some sort i have been reading about them for a while and now that it is summer i would like to get out and build them .
i will list the t/s parameters i have from the woofertester2 and hopefully some one can come up with a good idea on what to do with these speakers
i have 2 radioshack 4" woffers drivers from the old linaeum speakers and 4 polk 4" drivers from the old ls/fx dipole bipole surround speakers with matching tweeters.
i have built sealed and ported boxes and have had good results so far but i think it is time to try something a little harder.
i am wonering if it is at all possible to use the 4 polk woffers and the tweeters that came along in those speakers to build the 4 main channels of my home theater, and possibly using the rat shack drivers as a center speaker just adding a tweeter
another question i have is instead of building 4 speakers can i build 2 with 2 woffers each because of the small size of the polk woofers like a sealed or ported box by adding more drivers you get more output ???
i am trying to build something that i can set on the floor and not use a stand and if that means adding extra height in the form of a empty sealed box of the same size to make them taller i will
here are the ts specs
