Ok, so I have been dreaming of building a sub woofer for a while. Financially I could not afford A huge sub and with my NatP towers going as low as they do I could not justify building a rinky-dink 8" or 10" sub, too much overlap in capabilities. Anyways perusing the forums I saw "Zaph" was selling off a RS15 for $100. Needless to say I now have a mission to accomplish. So I will keep my latest efforts and tribulations up here.
The first tribulation I should mention is with finding an appropriate amplifier, a venture on craigslist brought me to a 1000W Velodyne amplifier. At its owners house I hooked up the only driver I had on hand to see if it would put out sound. (an RS225). It clicked allot, It was a class D amp and I imagine the clicking was do to its "D'ness" being broken, It had a few unlabeled tabs on it so assuming I had wired it wrong I tried the others, well at the first gentle brush against the accursed tab I hear what sounded like a loud gunshot behind me and the smell of "something" burning. My aluminum cone RS225 was now the first Dayton Midbass dome woofer. In horror of the carnage and in lue of (later admittedly) being electrocuted several times earlier that day by the Amp, the Craigslist seller gave me the wretched thing for free. If I could fix It I would feel less sad.
Anyways on to better things, I now have a Big Beautiful Driver and a box about half complete.
The plan is a 3.1^' internal volume box sealed with 3 inch chamfered edges and spiked feet. I will probably put some figlerglass insulation inside too. Haven't thought things much through past that so if people have porting recommendations stuffing ideas and the like its welcomed.
One question, on a sub, besides aesthetics, is surface mounting a woofer bad on sq? I know its bad on tweeters and midrange. I don't have the gear on me to flush mount.
