To determine if this Vifa will likely work in any sort of TL, we need to know the values of its T/S parameters. I tried running them down yesterday but couldn't find any, not even old ones from Vifa. Besides, it would be far better to know what the T/S values are for YOUR drivers, which seldom match those from the manufacturer.

I did enough modeling using the specs you linked to know it will work well in an ML-TL, and work pretty well in a tapered TL. Tell me what you had in mind to build, a 2-way or a 3-way, and if you have a cabinet size/shape you're after, particularly any maximum dimensions like depth or height. I won't respond again until tomorrow, however, as I'm shutting down my computer for today after this. Again, it would be wise to measure the T/S values of your drivers as the accuracy of the modeling is entirely dependent on them.

I have in mind 3way speakers with 6 inch kevlar B&W cwm 650, I must cut vifa on 200 to 250Hz becouse of mid, dimensions are not important, I have big room :-)
Thank you wery much

And if I find someone with equipment I will measure my drivers.
Good night
