Hi guys, I will be building my first WO but in my country there is no exact 3/4" (19mm) thick MDF panels. What we have here is an exact 0.708" (18mm) MDF panels.
As the plan says that when using 3/4" (0.75") thick panels, the throat will be 1.25 x 1.25, and enlarging this opening will raise the high frequency cutoff point.
So I guess if my panels is only 0.708" (18mm) instead of 0.75", the throat opening will be a bit bigger than 1.25 x 1.25.
Will it be any audible difference as I will use it primarily for my home theater subwoofer.
If that is a problem, I have an option to use a plywood combined with MDF as a single sheet which will be exactly 0.7677" thick (19.5mm). This will make the throat slightly smaller than the original 1.25 x 1.25 plan, which I guess will lower the hi freq cutoff point.
Can anybody advice me which way to go?
Oh, another question is, do I have to put some absorbing materials like rockwools in each of the 'magnet chambers' ?
Thanks a lot for anybody who can help me with this.
I am expecting my DHM108 drivers and Dayton SA1000 amp to arrive anyday next week, so I am so excited to start building the box from now :)
