I am aware of that driver. I would discart it. Too high Vas and too light curved cone. Risky for this application in my eyes. 
Nikon and Canon people should not be married to each other. Why did you let this happen?

Does anyone know if the Faital Pro 18XL2000 is a good input for scoop/ hog?

Eighteen sound LW2400 IS DISCONTINUED, now the substitute is LW2420. Its very similar but with more power handling (1300w).

Has anyone ever tried this on scoops?

Follow the T/S

  • Fs 33 Hz
  • Qms 7
  • Qes 0.33
  • Qts 0.31
  • Vas 255 lt.
  • BL 24.6 Tm
  • Xmax 10 mm

That driver is reflex driver.

Look at 18LW2600.

That will rock in right Scoop, but maybe not Superscooper.

Will require understanding of matching driver to Scoop throat.

"The 18LW2420 is an 18 inch extended low frequency loudspeaker designed for high SPL subwoofer applications in either a reflex, bandpass or horn loaded configuration. "

"The 18LW2600 is a 18" (466 mm) extended low frequency loudspeaker,especially designed for use in vented enclosures."

Since Iā€™m sure Iā€™m not the only one very, very bored of the ā€˜nudge nudge wink winkā€™ cyclical posts on this section, hereā€™s a comprehensive set of guides from the very experienced Martin J. King on all aspects of designing a well-performing rear loaded horn speaker.

http://www.quarter-wave.com/Horns/Horn_Theory.html

Sections 7, 8 and the two additional articles are the ones of key note, but itā€™s far easier if any interested people work through them sequentially. His MathCAD sheets arenā€™t available any more, but all the relevant equations are included (with all variables clearly defined) and Octave is free if youā€™re the scripting type.

The short summary however is that a ā€˜scoopā€™ behaves as a transmission line at all low frequencies of interest, and the ā€˜horn loadingā€™ part isnā€™t really taking effect until the ā€˜mid bandā€™ of the design. The throat acoustic impedance target isnā€™t really any different to other highly damped loadings. Watch the volume velocity and compression ratioā€¦ plenty of illustrative examples throughout.

Happy trails.

one of the best speakers i have heard lately is the b n c 18sw115 i know its been out a while but wow what a beast ,obvz for med to large chambers  by default because of the depth ( 226mm from back of mounting flange ) but  can do a return on the throat to load it a bit more if needed , we ab tested with 1852s and the 1852s blew up, not in the same league, the b and cs lasted all day as was a afternoon session 2 till 11 on the night :) amp was a itech 12k with 2 a side 32 amp feed limiters set just under clip but no clipping

Isn't that the driver Tony was putting in most of his cabs?
