Default designing crossover and enclosure without a data sheet.Help please

hi all

I have just got these drivers TC14wg0508 i have done endless emails and research on these and i am beginning to loose hope.

they are made by VIFA audio i have emailed them for a data sheet and they have never replied to me. the only spec i have is something i found on a website that the closest i have got but its the WG06 not WG05 posted below

any idea how i would calculate crossovers and box volume (on about building a 2 way enclosure tomorrow)

hope someone can help

Many thanks

Wez

If you don't have the T/S params, your best bet is to measure them yourself.

If you have a desktop computer, then the built in sound card should be adequate. for a laptop an external USB sound card is probably needed (as laptops generally don't have a line in).

I use REW for software. available here --> REW - Room EQ Wizard Room Acoustics Software

The help files for REW should have info on making a suitable cable and doing the measurements.

I very much doubt it...

More like 5.5" drivers in the 149mm rebate Vifa tradition:
Vifa Tc14wg49-08 Polymer frame
Vifa PL14WJ-09-08

Paper (?) drivers suited to 9L closed box by the look of the Vas of 9L and Qts of 0.51.

This Troels Gravesen design would be about right electrically:

I was going of cone area.the drivers are from Rouark audio who have kindly donated a set of drivers and tweeters that would match my college amplifier project. the 5.5" driver shown above looks much cheaper in design than the set of vifa i have.they have more of a shiny plastic coating with a wooden dome dust cap (i think there called that ) was hoping to make a two way ported enclosure today but will have to put it on hold till i can sort the dimensions.don't fancy ordering the birch ply for it to be all wrong

It's called a phase plug, and is usually made of plastic...

Are we looking at drivers that resemble these in the Ruark Epilogue variants?

Do the cones look like polymer or paper from behind?

It's hard to say that you wouldn't need to make slight crossover adjustments with a new speaker based on visual inspection over a forum, despite similarities with another design. That said, I believe System7 will get you as close as one could.
