Have final number on building subs and below is my cost breakdown. Depending on driver selection along with amplification, very easy to spend less as those are two major expenses. Obviously building your own subs will be more cost effective than purchasing commercial and hopefully, will achieve better performance.......though jury is still out on that one. Project should be done in middle of February which is anticipated delivery for UM drivers.
I decided to go DIY to acquire skills in understanding the science behind theater sound and develop a hobby in my retirements years.......I'm most definitely a tinkerer!
I have not included DSP expense since my intent is to purchase Trinnov TEQ-12 this Spring but may look at MiniDSP for hold over until June. I had all but sent in a check for MiniDSP 10X10 but after further research felt system was limited.
$482 Two Ultimax 18 inch drivers- have two more UM-18 drivers that need cabs built
$650 Two channel 2022 watts X 2 in 4 ohm or 3750 watts X 2 @ 2 ohm pro amp
$334 Two Diysoundgroup cabs includes shipping
$34 16 oz + 8 oz Tite bond II glue, rollers, primer
$24 Two cans Rustoleum flat black paint, two cans Rustoleum truck bed liner black
$118 100ft 4-wire 12 gauge, two 15 ft Speakon cables, 4 Speakon wall connects, 4 Speakon ends
$1642 Grand Total
You could easily lower amount by $450 by using Parts Express 18 inch HO Reference driver and Behringer inuke 3000/6000
Because I'm attempting to equal or improve performance comparable to my JTR S2, I've incurred additional cost. The goal is to reach significant output levels below 12 hz and UM drivers with 2200 watts per pair will have enough power to do so. Much of amp wattage will be used to reach close to max excursion and will need significant boost below 20 hz do so. Expectations are not to stress drivers but to have significant headroom for max bursts.
Hope this helps fellow AVS members contemplating DIY. In reality it has been easy so far and has been quite enjoyable........but the hard work to integrate is still forthcoming. Please keep in mind this sub build performance level should be on par or better than my $3000 JTR S2........Edited by doublewing11 - 1/14/14 at 8:15pm
