Hello all,
The TL design programs are Greek to me so I'm just going real basic planning for a classic tapered line with 125/100 sd about 8ft long for 30 hz. I've found two 10" woofers that fit my requirements for 24db crossover @450 hz but I have no idea if they are good for TL application. Someone please have a look at the specs below and advise on which woofer is best for a TL (other advise is welcomed too):
Driver A: Fs 21 / Vas 5.58 ft3 / Qms 3.68 / Qes .37 / Qts .33
Driver B: Fs 23 / Vas 6.85 ft3 / Qms 3.52 / Qes .58 / Qts .41
thanks,
Charlie

I spent time here helping you and didn't even get a response for my efforts, instead starting this thread, so I think I'll pass this time around: http://www.diyaudio.com/forums/showthread.php?s=&postid=1462036#post1462036

thanks for your help
GM:
Please accept humble apologies for being unthoughtful. Believe me, your advice did not go unheaded-- had you not pointed out the futility of my original box design, I might have used it with disasterous results.
As it was, I devised a radically different design using a still compact but much larger box volume with longer 9ft line using Roger Sanders' cookbook recommendations for line sections of 125% of cone area at the front and 100% at the terminus. Having already offended your hospitality, I was then too embarrassed to ask you to run another simulation. I've completed the speakers and I think they sound great -- not sure if frequency response is better than a sealed box but I'm convinced the resulting lack of coloration and overall sonic character was worth the effort.
Anyway, I just wanted to apologize and thank you for your help.
