that sub's hardly moving

[wojteklowicz]

good :D

[Raal777]

so what? and not 130 lammh is rated at 126 dB check the manual smart guy.

[Raal777]

the point when I made this video, is the excursion of the DD driver... DD subwoofers dont have to do a lot of excursion to make big pressure level, maybe in the video Im giving to it around 800 clean rms, the hugeee box is tunned at 57 hz, mdf 1.5 inches, 4 ft³ box after displacement and a massive port... the HU is an Alpine 9835 one of my favorites, because I can make pass band cuts, the system now have changed, same HU, mid low/mid /mid high wit the new amplifier Alpine

[Bsktbll895]

800 watts rms? The Mmats DHC1400.1 puts out 1500 rms minimum. You replaced that amp with an Alpine amp??

[Raal777]

the box was made only for a SPL purpose... not a music box, so is not recommend with music signal and is dangerous for the sub with high power, I keep my equipments in very good conditions, so in that test I didnt use full power only around 60% of total power and have around 80/85% of efficiency.. so make some maths with 12.8 volts.... around 1260/1300 real rms watts not 1500 wrms. The alpine only for low mid in bandpass and the JL Audio Set in hibrid configuration now.

Actually, they only go up to 126, and he hit 126 in the video.... so conceivably, we have no idea how loud it really is. Can't really say by the video, but I'm betting over 130 easily.

[mysubsbang]

possible there nice subs but my 2 12's hit 143 :)

[SeanFarley25]

thats fucking horrible

[SeanFarley25]

wow.... all i gottta say

Fart box.

[rowanlloyd]

what?

[bigchevy4]

dont listen to otacrunk hes a fuckin retard

[rhode123]

the prodigy - smack my bitch up

[carbf1942]

whats the name of this song

[Otacrunk]

Nice sub, nice box. But it needs more power, shes hardly movin. Good song too!

[rowanlloyd123]

it aint movin cos its an SPL box

[efrankie90]

Um. SPL = Sound Pressure Level iirc... isnt there more pressure generated with more excusion?

[subman1992]

ahh but isnt the sub playing its boxes tuned frequency?

[efrankie90]

Nah. The tuning is the tuning of the box, not the sub. I don't know much about it or how to explain it. The higher the tuning (if it's around 50 hz) that's a straight up SPL box.. It won't get low, just loud. If it's lower (generally around 32 hz I think) it'll get low, but not as loud as a 50 hz box. Lower tuning also sounds better I think.

[CourtneyChaos14]

Nope, run 55hz threw your sub at your normal volume lvl, then run like 36hz at the same lvl, the sub will move more at 36hz but will be louder at 55hz.( if you don't 36 and 55 hz i can send them to you)

[Raal777]

in 1 day I`ll be in a Db Drag Racing comp I`ll use that same box, works well.

[Raal777]

Thats isnt a musical box, in Termlab I hit 146-148 with 2,000 wrms Db Drag :p

check my register in TL page

[SeanFarley25]

thats all ur pushin, is under 130? sucks haha try makin ur port just a few inches not as wide

[Raal777]

in termlab Street A maximun score was 146.1 dB ;) Db Drag same amp.

[Raal777]

the sensor only reads at 126 dB.... I compete in Db Drag Racing there are my numbers
