Very strange, every time I read a post by you it reminds me of a Bill Fitzmaurice post. Same use of language and so on. But I assume you are not the same person.

Best regards,

The comparison is most flattering, thank you, but alas I am not he. I'm Batman.

exactly, and with accumulated compromises with horn design, its best to try and minimise these, so theres no harm in trying.

although i dont see how it will help much in a scoop for upper band frequency response due to the pathlength differences from the direct radiating element and rear horn loaded. (42cm you say eh!?)

the modulation thing was from the bass modulating the upper freqs of divisable wavelength, but i cant remember where i read it..

its not my thing, but as mykey insinuates; people who like scoops will probably like the "dirtyness" of the sound this would produce.

howd it go mykey?

Well, if it doesn't work, it might still be usable by lining the curves with sound deadening material - this might reduce the transmission of higher frequencies through the horn path.  Could be worth a try rather than relegation to firewood..

when played at full range, the mid is quite exceptional (effortless)

though some one did mention that would happen?

all it needs is a tweeter above.

ill put some pics up soon

at the moment the cab width is 580mm im increasing it to 610mm.

scoop with a tweeter on top. actualy alot of bass guitarists [ok a particular group but a reasonably sizeable one] with particular playing styles would bite your arm of for such things. i think scoops have got a fair few more uses than peeople like to admit!

some build pic's

inside the throat..

and the scoop.

Notice that it has no brace at the mo the 2 sides were vibrating like rubber bands, and the baffle is machined out for a pd the hexagonal shape but i dont have a pd so i had to put a different baffle in front and use this 19'' im trying out.
