Does anyone have any advice or previous experience of building scoops for Fane 18" 400W drivers?

I am poised and ready to build, using the Super Scooper plan.

I'd appreciate any wisdom that may help me avoid any rookie mistakes!

Cheers.

Are these the really old Collossus Studio ones? I have a pair of scoops with these in and they sound awesome, but im still searching or the plans.

Yep. Studio Colossus 18 Bass.

My other option is to scale up the Fane 15" scoop plan from their loudspeaker design book.

I found this on a previous forum....

The Vas for the Fane's is 366, so ideally the front chamber should be around 90 litres.

Here's a question.....

What's the volume of the front chamber on the Super Scoop? I got about 56litres, but not certain exactly how much of the front chamber is the front chamber (.... you get me?)

Put Fane 18B400 into chamber of 90 litres, and it's Good Night Mr Bond.

I may have got the Vas wrong for the Fane's. Looking at the Thiele-Small database I reckon it's 209 litres not 366.

Build a super scooper, ensuring you have bib handy, for drooling at the effortless notes rolling out, when you load it with 18B400.

EDIT:18B400 has parms similar to Bline 18-800, and that is a stonka' in SS18.
