Autruche Posted October 26, 2011 Report Share Posted October 26, 2011 I've never built a sixth order bandpass and have no experience with them, so I figured the best way to learn would be through experience. I just picked up a brand new circular saw and have had the itch to start building boxes. I didn't have much wood laying around so I just used up what was laying around (Brich ply, MDF, and, yes, Particleboard) as it's just an experimental box anyway. Anywho... Here's what followed. Did up a design: 3 cubes rear, 4 cubes front, 33 sq in @25Hz for the LF port, 144 sq in @65Hz for the HF port Onto the build Started with the pieces cut out For the sides and back I had to use 1/2 particle board cuz it's all that I had laying around. So I doubled it up with glue and screws. Then I had to trim off the exess screws sticking through the other side. Much better Need Test Tones/Sine Waves?

Autruche Posted October 26, 2011 Author Report Share Posted October 26, 2011 Then I cut out the sub hole in the baffle. Then I cut out and assembled the HF port And then the front piece for the box Here's how the HF port and the Front go together Then I cleaned up the HF port with the flush-cut and round-over bits in the router. Then I put together the LF port. I was worried that with such small port area for the LF port that port noise would be an issue, so I decided flared openings would be the best bet. I first tried to kerf MDF but that didn't work for me, it just became brittle no matter what I did so I just used cardboard tubes for the flares. Then I mapped out the layout on the bottom piece. Then I pre-drilled everything and glued and screwed it all up. Had to bust out the corner clamps for the sides. If you don't have some, get some. They are like having 4 more hands. Got that all taken care of Need Test Tones/Sine Waves?

Autruche Posted October 26, 2011 Author Report Share Posted October 26, 2011 Then I went to dry fit the top piece and ran into this issue. That should be at exactly 15 Solution? Much better! I then dry0fitted the face of the box on to keep everything strait while I took the top of to glue it up. And this is why I don't buy cheap shit. No matter what you can't get this POS to not eat up belts. Then it came time to glue and screw the face on. Added some speaker terminals Before round-over: After: Down the HF port The Baffle The LF port opening Down the LF port And that's all I got. I still have to drill out the mounting holes for the sub, but I let a friend borrow my MT so I have to wait for him to stop over again for that. Hopefully it sounds as good as it looks, going to be testing it out today with a 15 sitting in my house. Need Test Tones/Sine Waves?

Cashdollar2009 Posted October 26, 2011 Report Share Posted October 26, 2011 This looks great man! I've had the itch to try a 4th or 6th experiment for a while. Seeing this much go into just testing make me want to try it more. Be sure to post some texting results. Good work. On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free.
