Default markaudio 12P in superpensil --advice needed

My carbinet is ready and i need some advice :
1) Do i need to line the inside of the carbinet with Insuflex--the aircon duct insulating material ?
2) The carbinet is braced and i intend to place extra bracing to support the polyester fill in the carbinet . Is this necessary ?
3) What internal wiring works best with the Alpair12p? Solid core or 18G multi-core?

thanks

PS i have trouble uploading the pictures.

1/ optional, but some inner wall damping near the driver to reduce reflections might be helpful

2/ At the densities used, and with the braces you already have, friction will usually hold it in place

3/ we use a pair of 24g solid CAT 5 strands.

Hi dave,
thanks for sharing your experience.
What is the sound difference between solid and multistrand?
I notice that many fullrangers use cat 5 cable.

"We" use Cat5 because that wire size is sufficient at the power levels most full-range drivers will handle. There is a technical advantage to thin wire, whether it can be heard or not. On the other hand, I am building a pair of speakers with 18ga silver plated copper because the customer thinks he hears the difference.

What kind of material would you use for this application, dimensions etc?

Thanks a lot

I'd use 12mm Ultratouch cotton felt, but any similar thickmess wool or cottom felt would suit.

I can only source either 10mm or 16mm of this...
