iv settled on the design for my new sub build an im going to start buying the parts so

if i go with a Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil wired to 4ohm an placed in a 18in by 60in

sonotube with one 21in by 5.220in port tuned to 17hz

an powered by a Crown XLS 1502 525W 2-channel Power Amplifier in Bridged 4ohm for 1550watt

with gain knob to full would i get an audibly chuff id be using the 10band parametric eq in my outlaw audio 976 4
receiver

the sub ch has a hi an lo shelf an 8 adjustable bands all 10 can be tweaked for 2ohz to 20khz +3 to -20db an the 8 bands
q goes from .5 to 14 for some fine tuning

an id use REW WIZARD to do it


drawing is a rough concept

cant really show more till all the parts are bought an arrive the sonotubes are a set back as the shipping cost changed with the company i was going to go with tho they did mention they would when i first look at deco-cretesupply.com

2 x 18in by 60in ran 173.50$ with fedex ground the cheapest at 210$ so 383.5 total not bad i thought for to cabs at less then 200$ each for 8.3ft3 but now is 430.35

an why i didnt get when less i did think i would go up that much that fast at save up to get the amp an driver first was my goal tho i did manage to get the amp while on sale an its on the way right not

so im reassessing wither or not to either go with another company that sell by the foot or to go with smaller cabs

the original design called for an 8.8ft3 with a 21in by 5in port tuned at 17 or even two at 37in long but that would very costly for the ports so one

v1

54628


v2 with one port

this sees like the happy trade off for size to cost as two 18in by
48in will run me 138.80$ with 122.71$ in shipping for a total of 261.51$ with the desired sub do you'll that this would be a good compromise with the one port per cab

these are my end caps to be custom cut by sendcutsend.com

theres two different quotes one is for layered hardwood mdf at .125in that would be layered up to 1in for the port side an to 1.5in for driver side per cab

the other quote is for 1in thick for both sides with a mix of .125in an .5in for the port side an two .5in layers for the driver

54630


54631


im good with the cost as iv had work done by them before but my question is do you'll think the both endcaps for these cabs with these drivers need to be thicker then 1in to 1.5in

or is 1in on both ends enough either way thers some steel outer rods that are planned to be used as like a vice grip to the outer frame that also serve as the legs for the cab
