10" RE XXX quick log

[soloXgt]

Against some peoples wishes and opinions, I went ahead and built a 4th order for the XXX. The kid wanted to build it free, how could I say no? Don't have all the measurements, forgot them at home but I think the sealed chamber is .5-.6 cubes after displacement, ported chamber is .3ish cubes and port is about 56" long giving a tuning freq. of about 54-55?? port size is 22sq. in. I forget. Curve mimicked .4 cu. ft. box but with 3-5db gain throughout until leveling off IIRC. Criticism always welcome, good or bad. Kinda crappy cell phone pics but, meh. On with the pics.....

why did u tune so high?

[captaincheesey]

Unhappy XXX is going to be unhappy

[soloXgt]

i let the guy have his fun building it. It still hits the lows with authority. I was wondering the same thing, but as of now, without playing with the gains/eq too much, I can't complain. After a week of breakin it in, i'll play with it more and tell how it is

[KHARPS]

Looks good. Have you listened to it yet?

Nevermind.

This??? That's just crazy for a SQish sub. :crap:

[soloXgt]

I think the tuning of that port is more of a cut-off frequency. Correct if im wrong

[MisterGrubbs]

Not really that retarded high. In fact, it's reasonable. Consider the fact that the 4th order will allow the subwoofer to freely play some 2 octaves(roughly...??) lower than it's tuned to, that's if I'm not mistaken.

And as he stated in the first post, he wanted a large gain at X frequency, maybe he wanted that larger gain higher but either way he can still tune it with a relatively flat response tuned that high or not.

I see

I don't know too much about 4th order :crap:

[Ray21]

How does that design plot out? And have you measured the freq. response?

Looks like he did a good job building it, aside from the port edges not rounded. I probably would have went with more port area also.

[soloXgt]

When he got done with it, he said he shoulda gone with more port area...kinda late now

[hazardous0388]

holy sub batman. so much sexyness with that 10 inch. i wish i would have bought up 8 of those motors back in the day... *sigh*

[soloXgt]

should have got em

[JBGabriel]

Hows this one compared to the 12" XXX?

[soloXgt]

never really got to play with the 12" like I wanted to. so couldn't honestly tell ya

[DB-Audio]

nice job man looks good.... that is a bit high for tuning but if it suits the kid who you built it fors tastes then no complaints are you planing on wraping it or painting it at all

[soloXgt]

prolly not for a while, pretty busy with school
