better sq with 300 watts rms? IDQ 10 or SSA Dcon 10?

[stanky1219]

more xmax and bigger coil than the dcon too.

im gonna run it in winisd and check out some box size options.

I'd say it's far more dependent on the box than the subwoofer in this particular situation. Build an efficient box and either one could sound great off 300w.

Have to keep in mind that winisd plots based on a point source with infinite space around it, not reflecting performance in car. I also prefer to model in Unibox

at 1.3 cubes tuned to 28hz winisd is showing a dead flat curve from 30hz up. nice driver.

yeah but with the eq and epicenter i should be able to get around the peaks and valleys of cabin gain. box is essential but the processors will be a big help in getting dead flat response.

it does well in either. around 1.2 ported or . 6 sealed iirc. your little toyota will have alot of cabin gain down low. id go about 1 cube ported in the lower 30's personally.

probably gonna go ported cuz one 10" @300 watts versus components @200 watts right in my face. i think i will need as much output from the sub as possible to keep up with the comps.

You need to remember that you're going to have a bloated bottom end with cabin gain up to +10 dB down low. If you have the space for it, I'd do an EBS enclosure

tune higher then?

Dead flat is almost impossible in car especially without RTA. Just do whatever sounds best to you once you get it installed. Even I don't like a perfectly flat curve - I like a bit more bass/midbass and a rising top end in the treble.

i just did a 10 inch diamond d6 in my s10. they recommend 1.25 ported. i did 1 cube at 31hz and the bottom end is still a tad boomy for me. should done .8 at 30hz.

me too. and there is a local shop here that has a audiocontrol sc-3055. thats an rta as well as spl meter right?

no. not with that sub anway. sq usually lives in the low 30's or high 20's ported, but some subs are built to be tuned higher and will sound nice tuned to 38 hz. that sub wont like higher tunings i dont think.

 

[stanky1219]

i didnt think so. i was thinking between 27 and 30

it will be a very long port at 27, unless you sacrifice port area, which can wreak havoc on sq. 1 cube at 30-32 would probably work fine. if you want it a little boomier, around 1.2 at 32-35. if you want pure sq with a big sacrifice in loud, do .6 sealed.

Both the Dcon and IDQ are excellent SQ choices, both are proven sub woofers. Keeping in mind there are so many factors that go into accurate sound reproduction past the sub woofer. It is a win win, specs wise the IDQ favors sealed a little more, where as the Dcon is more suited for ported then the IDQ, but either can be installed in either enclosure with great results.

g2g take kids to doctor.

without the resonant frequency of your truck, and alot of trial and error to interperet the graphs in winisd, youll never get flat response by box design alone. it looks like you already planned around this by sampling the signal anyway.

 

[stanky1219]

well i think i'm gonna steer toward the dayton. bigger vc , more xmax , and it can deal with a cramped box a little more than either of the other ones.
