[quote name='Buck']I was jc. Just getting the picture. You can't beat testing.[/QUOTE]
true that. I need to beat a 148.7 on under 1k clamped. thats the record held by @n8skow ; I might get it, but I doubt it. I hope to come close though. still lots of work to do, this is only the second day of testing, so far I have gained 8db since yesterday lol

i figured why not test port forward lol, never know what could happen. All in all, I am learning a lot, this being my first actual 4th order build. if I could burp a 146 or 147 I would be quite happy, its nice that im louder sealed than outlaw though, by almost 2 db! lol

and the sucky part is, ive been testing music all day, because I cant find any 0db tones lol, im sure burps will gain me too

That's a very significant difference.

That's a very significant difference.

from what I have seen, its pretty common for that to happen with small cone area/large cabin setups. which makes sense.

making progress. only thing I did, was to actually set my gain with my scope instead of guessing. but this score is vehicle sealed, wired to 2.6, probably rising into the 5 or 6 ohms range, so that should give me around 600-800 watts. not too bad, but no where near where I want to be. peaking looooow too. which I like.

I used the dats to find my rise, and I rise from 2.3 ohms, to 8.93 ohms at 32hz. so 3500/8.93 is 391.9 watts....

You need to bolt your box down so you dont get so much box rise.

LOL! the dats is off I believe, but a 4th order typically has a lot of rise.

test test test test lol lots of variables with 4th orders.

Yep mine wired to .5 and rises almost to 5 ohms.

yeah... so im doing a 144.5, sealed, on 397 watts or so... no big deal lol

What frequency? Isn't it low?

I compliment your db achievement.
