Just finished the first of two subs I'm building

[sine143]

Well guys, I just finished my first tuba 30. Was a week from start to *finish* (we still need to roll duratex over the latex base coat), but I only did work on the weekends. This is number one of the pair, both being driven on a single channel with a crown xti 2000. I have to say I'm very happy with the build, the plans (http://www.billfitzmaurice.com/) were very good, and the forum over there is very helpful.

I can get this sub to a nauseating level in my room at about 40-50% power on the amp, with just a 30hz test tone. The walls start shaking pretty bad. At 90hz, 2-3 out of 20 clicks on the amp its almost unbearable

Heres a pic for ya! God I am so stoked.

that looks like a beast. total cost?

[sine143]

~99 for the driver (delta 12lf. Should have gone with the 3012.... but it was double), this is after shipping (15 dollars)

~75 for the wood, and we have about half a tuba left over

~10 dollars for pl glue (stuff of the gods)
~15 dollars for plans
~15 for the corners, speakon jacks, screws and casters
~8 bucks for a quart of black matte latex, still 3/4 full after 2 coats here.


Then of course we spent about 40 bucks on cables. Bleh. and we already had the necessary tools (handheld circular saw, Drill, Jigsaw, clamps)

It brings the sub itself to around 215ish dollars, but since we have glue, and screws, and wood left over, I anticipate the next to come in at around 150.

damn, not bad at all. you had a chance to get an RMS level on it?

[sine143]

Have an spl meter to test db with, at home (not at my apt). I'll get it mailed to me I guess. My multimeter is messed up (measures 150 volts from all the wall outlets in my house) so I cant even accurately gauge what I'm putting into it for wattage. Thankfully, I'll probably have my fluke mailed to me with the spl meter =]

If you want to know more about the design itself, you can check out their website. They have like a ton of frequency response graphs and comparisons.

word, thanks for the link man!

[sine143]

No problem. I'm pretty confident in the design, although this is my first sub of any decent power or size. I am so ready to build the second one and v couple them.

We will be giving them the first real test on thursday (gotta go pick up the tops/get to a place where my neighbors wont kill me). We'll run it wall loaded with the tops in a fairly large semi circle shaped room (radius of the semicircle is ~ 30 feet).

Can. Not. Wait.

dope man, let us know how it goes definitely! really would rather make my own than pay out the ass for one
