i'm probably going to trade the three 15"s i currently have for 12 10" sd-1's. i've only got room for 10 of em, and this is the design i came up with. its for a cuthrough in a truck, you think these will compete with the 15"s off the same amount of power?
i think it came out pretty decent for my first time using sketchup.

Might be some cancelation with being that deep and narrow.

x2...deff. gonna be cancellation

hmm, forgot about that.:crying:

i can fit even less in a V, which is what i originally planned to do. i might need to try something else.

Also with that design watch out for the magnets hitting with the front 2 subs and the ones first ones in the tunnel.Don't know if you took that into account?

just do 4 12"s in a v shape ported...no cancellations and LOUD!!!

What about a "w"

This truck with a similar design seems to be doing ok:

Only 8 woofers in a similar channel. Sure there is probably some cancellation but it appears that the retarded amount of cone area still gives some good output even with the cancellation. 155db at 32hz ain't bad :laugh:

not sure which mic that was on btw

Sketchup is sweet huh? I use it for architectural visualizations and stuff like that. If you ever feel the need to have more realistic renders, There is a program called Kerkythea that will accept Sketchup exports, and supports raytracing, reflections, lighting, shadows, ect.

Probably more than you care about, but oh well.

so will i run into cancellation or not? i thought that that only had to do with higher frequencys or something like that.

i only see 10 holes for subs :fyi:

...... i said i only had room for 10 in the first post...... :fyi:


i was just going to sell the other 2 locally.

You fail at reading.

instead of angling the 2 outermost subs, keep them flat and angle the 2 walls of 4 into a slight v

better? i'd probably have to countersink the two subs closest to the back wall.

looks better. try doubling the wall thickness with the last 2, itll increase the clearance by 1.5"

you may have basket/magnet clearance issues in the rear with the angle, also how are you installing the subs, screw em down first then mount the board into the box? all in all looks good just minor stuff to refine. sketchup works pretty nice dunit?

edit: at least the bottom will be easy to make, just cut a full sheet in half

that looks good.Or you could take out the 2 front ones and widen the tunnel a bit.You would lose those 2 speakers but 8 should be **** loud.Just a suggestion.

well originally i was going to do 16 10"s, and that number is all the way down to 10 or possibly 8, so i think i'm going to scrap this project and pick up some beefier 10's like cvx's or somethin and do 4 of em, and when i get more money down the line double it to 8 ported hopefully.

Is this actually a design, or did you just draw this up?

:confused: it is all to scale, it would fit in the bed of my truck. all of the cutouts and OD's are the exact size of the subs i'd be using, so idk what youre asking. it is a design and i did draw it up?

What he's asking is did you design it to any particular specifications for airspace and these particular subs, or did you just throw it together in Sketchup?

5 speakers, in 4 cubes so .75 cubes per speaker. yes, i did.
same for the other side, thats just what the specs called for

Enclosure Recommendations:

0.5 ft^3 - 0.75 ft^3 sealed

thats the internal dims of both chambers, i didnt account for the little angle because i figured driver displacement would kind of cancel out.

:rolleyes: i think i can multiply three numbers together and divide them by 1728

no need to get snippy.

you asked me if the design i made was accurate, i responded with yes, with evidence to back it up. you questioned it further, saying you thought i wasnt right. i provided evidence once again showing i was correct. what's the problem? you don't have to assume everyone is an idiot :veryhapp:

All these people saying you'll run into cancellation blah blah blah, pure bull ****. You don't have to worry about it with bass frequencies, because the waves are far too long to cancel each other out in most vehicle set-ups.

i thought i had read that, thanks for that info. those 10's are gone anyway, but i think i'd rather just run 4-8 quality 10's ported with the space i have.

btw, the second design was 4.25 cubes per chamber, making each speaker see .85 cubes. after driver displacement of around .05 i'd guess (couldnt find any specs) it'd put it in just a tad larger box then recommended.

dims if anybody is interested

if anybody wants me to model up their box i'd be happy to lend a hand.
