About to try some idea's, and wondering if anyone out there modified any plans they had seen/superscooper, without completely re-modelling horn section and had success by trial/error/ear.

E.g subtle mods to:

scooper to work better with drivers other than V18,
enlarge chamber/throat, by moving baffle or other internals,
mod for o/p to be flatter in 2's/4's.

Been spending far too long on hornresp, and want other peoples different perspectives/physical results on this.

Model of tuning Scooper18 for V18 with:

Throat reduced from 792 to 615 (1/2 Sd)
Front Chamber reduced from 44l to 34l

SPL Plot is Horn o/p only for clarity..

Hopefully above mods require no changes to actual horn, by
just moving rear baffle.

Comments/Corrections anyone?

very nice levyte,

i have super scoops v-18 loaded, rear baffle moving would not work well i think because there is not much space behind the driver and the baffle, maybe a bigger triangle reduces throat and chamber?!

Reducing the chamber by 22% (e.g moving baffle forward) gives us 34.34l chamber, and approx 617cm2 throat ( I think..).






The rear baffle is originally 202mm from inside of front baffle.
(256 - 18 - 36).

Reducing chamber by 22% means rear baffle distance from front baffle
of 202 * 0.78 = 157.56mm.







As can be seen from pic. V18 is 169mm deep from inside edge.

If We use double size front baffle (36mm instead of 18mm), this will remove 18mm of V18 depth = 151mm

So we would have 157.56 - 151 = approx 6mm clearance between
V18 magnet and baffle in reduced scoop.

Comments/Corrections please.
