G'day Guys. I am friends with DaveS in Australia and about to build a WO32 using Vifa PL26WR09-08 Drivers. Qts=0.39 Fs=27

In Australia I can't get 3/4 inch MDF (19.05mm), closest is 18mm. Does the box need to be modified to take this into account. Works out that the throat of the box will be up to 4 mm wider than original design.

Also curious as to how Steve's DHM108B Driver works in the WO32 as Qts=0.68 and Fs=40.8hz. After reading most of the forum the Qts seems to be high. If using this driver how low will the box/driver combo go?

Cheers Andrew

Andrew,

 If you follow the lay out lines, your throat should be exactly the same as if you were using 3/4" MDF. It will how ever make the sealed side of the cabinet just a bit bigger which in this case, won't hurt a thing.

Mike, I didn't know you had a cabinet shop. Interesting.

Thanks BobZ.

Any idea how DHM108B sounds in the WO32? Does the High Fs mean the box wont play super low or does the box compensate for this?

Thanks for your help. I'll Upload photos in a month or so when the box is built. Cutting timber on 4/7

Cheers Andrew

Mike,

  I know what you mean......My son worked for a guy up near Hawi,  on the big Island, his name was Hap, did you know him?
