I am going to build a pair of FRFR cabinets and load them with the Celestion F12-X200's.
-- I am going to follow the Celestion Cabinet Design for this.
-- Yes I am aware of the Kemper Kone.
-- Yes I am aware that Zilla Cabs will build me one, but I am a hobbyist wood worker and want to do it myself.
-- I am doing this simply to see how my Profiler will sound in a true FRFR Thiele environment, I.e. removing
all of the speaker and cabinet coloration I can from the equation.
-- I want to see how close it would get to the tone I hear through my audio interface and a pair of 20Hz-20kHz studio monitors.
In the design specification comments with the PDF it says:
'Polyester wadding recommended, affix using staples'.
Being an exacting anal programmer I have a problem with this statement:
-- What is 'polyester wadding'? I am state side and am assuming this is polyester batting as in sold by the yard at fabric stores.
-- If I am correct about this I see that batting comes in different 'weights' (light, mid, heavy and ultra). Would the weight matter?
-- Do a line the entire interior of the cabinet with the batting?
I am pretty sure the 'polyester wadding' is there for sound deadening. I am used to using
Owen Cornings 703 and sometimes Roxul for sound deadening applications.
Since the Celestion design is clearly for a DIY'r (wood glue, screws, table saw, jig saw is really all that is required)
perhaps the suggestion for 'polyester wadding' is their because it is readily available?
On the other hand if I where to utilize Owen Cornings 703 it is denser and thicker (1") and therefore would muck with the
Thiele design of the box (less internal volume).
My anal tendencies have me frozen like a deer in the head lights!
I asked this question of Dr. Decibal at Celestion and have received no response.
I suspect they think I am crazy.
Opinions (and I understand that is what they would be) on guidance are most welcome.
