Hello all, I'm about midway through my sonosub design.
I'm going for the Adire Alignment Design (Only took me 2 months to decide on a design! )
So, I've cut my tube so I'll have approximatly 214L (How much leeway would I have on the total internal volume, can I safely be 10L out of spec either way?)
Sadly, I don't have the precision flared ports, so I'll use the PVC method so many are fond of (And flaring them at the end with a round over bit)
What size/length of PVC should I use to reach the same porting as with the FP3 twin ports?
(So no one has the pull up the designs, it's 214 liters, tuned to 15.4 Hz, stuffed with 64 ounces of polyfill, using a pair of FP3 ports with 11" center tubes)
Also, I notice with sonosubs that everyone mounts the driver down firing, and the ports on the top. Any reason for that? I would much rather design it with the sub on the top, and the port(s) on the bottom. It will have a baseplate, so either way, it won't be blowing right at carpet. Any reason why I should stick the driver on the top, and ports on bottom?
One last Question, I don't really want to use any rods, I know I definatly should, but I'm hoping I'll be able to fight my way around them. I'm planning on cutting some 3/4" mdf so it fits in the end perfectly, then I'll just glue it in like crazy. I could also screw it to the sonotube, just around the back so the screws wouldn't be visible. (Not sure if the screws would be necessary)
But, with the endcaps glued in (with lots of glue!) would it 'work?' The entire weight of the structure should keep the bottom cap in fine (It will be wresting on legs, then the baseplate) Also, I can definatly put some weight on the top of it. (I figure with the driver on the top, there's 20 pounds, then I can stick an aditional 20 lbs of something up there, perhaps some marbel would look nice. I figure the glue, and the weight would keep it firmly in?
Thanks for any responces!
(PS, I'm in Canada, and looking for a BFD 1124DSP, and a QSC RMX 1450 power amp, to drive them both, anyone know of any Canada retailers that would carry these, or would order them up? I'm afraid of customs tacking a large duty fee on them)
