Hi Wayne and all,
I'm in the final preparation phase of a project, not my first, but my first solo project. I'm sticking as close to the plans as I can. In the onePi_A08_bass_reflex_baffle_cutout.jpg diagram, the port cutout begins 1" from the bottom and right exterior edges of the enclosure. With 5/8" material, this places the bottom and one side of the port tube 3/8" from the inside of the box.
From the page linked below: "It (fiberglass) should not cover the woofer or the port opening. If construction type fiberglass is used, the paper backing should be peeled off."
My plan is to keep the R-13 away from the port tube, by sticking it to the top side of the box (int. D X int. W), then the side opposite the the port (int. D X [int. H - 3.5"]), and last the rear panel ([int. W - 3.5"] X [int. H - 3.5"]). Are there any known side effects to this approach?
Second question: Leach says that the paper backing should be peeled off. Any idea why? I can't see why fiberglass glued to paper, glued to MDF would sound different than fiberglass glued to MDF.
Thanks!
