tort- It sounds sweet. ARC Audio is a high end woofer and it is built on sound quality. So, any type of music this thing just reproduces it all. From jazz to country to hip hop and reggae, I'm happy. Yes, the 8" wasn't loud enough, I wanted more (had 4 10"s when I was younger)
wildo- Very very very good question. My first attempt I had to dremel the ends off. This one shown above, I tried not to create the ends because I also wasn't sure how it's done correctly. I have since figured it out.
When you stretch the fleece, staple the ends, and overlap the speaker grill, don't worry about anything. Just go ahead and do it. DO NOT cut the speaker hole out and try to resin careful around that opening as I have done. Simply don't apply resin to the center area that you end up cutting. Same with the edges. Resin right to the edge. With mat, just mat right to the edge, and same with the speaker cut out, right to the edge. THe most important step is to then resin the inside of the box behind the fiberglass. You want to resin the interior sides so when you cut off the over hang, it's still solid. AND you want to resin around the speaker ring to ensure stability. So give a good coat or two to the entire inside of your fiberglassed fleece and 4 layers of mat. What I also didn't know is you can do multiple layers of mat without having to wait for it to dry which saves time. Then body filler+resin+hardener and make it semi soupy and cover our entire fiberglass front with it. Then, you'll be sanding for a while starting with 80grit, 150 grit and up top 400-800 depending on if you are painting it glossy, etc.
Also, I read afterwards, that the pros like to us speaker cloth better than fleece because fleece is so dense it does not completely soak up the resin. If you used speaker grill cloth, you might not need to apply resin as much to the inside the box. ANd also resin all edges inside the box.
