Another SuperScooper Doodle... Discuss

Right similar on this traces.. smiley20
As I have noted in other thread about tunable throat scoop - idea... it was intended to be medium chamber one (~62ltr. brutto - volume displaced by driver not excluded .. so with driver will fall in 55-57ltr.) with throat easy changeable from 3.8" to 5.1" without taking driver out.
... still think that there is no valid reason to build one like this? smiley23

From my experience of scoops, drivers, extensive testing, gigs, buying/selling, sound dude talk, I have arrived at 2x conclusions,

Scoop design can be optimised for one of 2x types of "scoop compatible" drivers,

a)Drivers that are optimum in tight chambers and tight initial throat
b)Drivers that are optimum in medium+larger chambers with loose initial throat,

Personally think trying to design a scoop for one particular driver is pointless, Also trying to design a scoop for all drivers is equally pointless. The only reason scoop owners use scoops, is for the huge efficiency within certain pass band, for given types of music. So optimised cab for the driver type is key.

The tight chamber scoop war is all done, and the winners are ASS, SteveB, Eminence.

The Medium chamber full scoop war has'nt even started yet, but the best I've heard (so far) is from Hangar Lane builder.

The test of the perfect Medium Chamber scoop is impressive SPL, extension, throw, cone control, with correct HPF,
using one of 2x particular drivers. (Which I won't say)..

All "IMHO". smiley23

have eminence a tight chamber?

Tight chamber/throat.

Would also describe JBL/Fane designs as Tight chambers/throat.

do you mean the original one or a less wider one?

195cm equates to almost 2meters or aound 6foot (masive boxes) :lol: Should it not read 195mm. I like the plans though.

:lol:

Yes it should read 195cm...

We often have a little doodle with Rog Mogales Superscooper 18, lends itself nicely to tweaking, and offers very comprehensive plans.

I'm estimating, the rear baffle should be approx 545mm long.

The "real" throat will probably fall somewhere on the small diagonal after the "pseudo" throat,
And will be approx 4" - 4.5", (101.6mm - 114mm), 609.6cm2 - 685cm2.

with this layout and these external dimensions I can't reach 195cm of horn lenght but 15 cm less...
In jbl layout and eminence too tha panel below the baffle help to encrease lenght, very simple trick very effective.
However I guess this layout loves not very low qes.
