Question About My Setup

[leescotty2001]

Here is a short video of my setup. Hard to see if I need to I will take it during the day so you can see it better. I thought this would hit a tad bit harder. I have an epic 160 doing the metering. My current setup is

Sony HU

Epic-160 not used during test except the spl meter

Rockford Fosgate T30001bd

3 Rockford Fosgate T2's 15''

I thought the box was tuned to 35hz

My question is should I get another box so I can get it louder? Also During the song it cuts out at around 60 cycles. What ever that is in hertz I dont know. I play the song Hoods run down by lil whyte and in the intro. I dont pick up the lows right before the song starts. Any help appreciated

Here is a vid.

how accurate is that meter???? and did u ever meter it on a termlab

[ChevyBoy]

60 cycles is 60 hertz. your head unit probably skipped then.

[LSN2meBoom916]

Cycles=hertz=hz.

same thing.

Need some better shots of your box, too dark in the vid.

"You thought" is was tuned to 32hz?..based on what info/specs? CFT/port dimensions etc please.

that IS slightly low for that number of subs/size and power. 3-T2 15's off 3kw "should" be louder but your box is the key to sucess or failure in this case.

I pull about the same numbers on the same mic in my Integra w/ 4-12's sealed off about 1200-1400rms.

If it doesn't play 60hz....does it play Other frequencies ABOVE 60hz? or just no/minimal output above 60hz?

If so I say check ur xover settings on the amp.

~2cents

so how accurate are those meters compared to a term lab

so how accurate are those meters compared to a term lab

off by about 3-7 dbz usually

[cartunez2004]

o ok this meter is suppose to be only .5 db off so i think ill buy this just to do some testing before next season

Well 60hz is way off imo. I think the box is small myself. It measures

50.5'' Length

20'' High

22.5'' Deep

Ports are

14'' by 2'' high. I dont know how far back it goes

There is a divider inbetween each sub.

Does this help any?

Here are pics

First flip your box over so that the ports are on the bottom facing the rear and see what happens. Next build yourself a new box. I'm figuring you have roughly 3ft of airspace & 28" of port area per sub. Go for 3.5ft w/ 50in of port per sub tuned to 32-35hz and you'll be much happier. Do you know if your subs are d2s or d4s?

they are d2's so i think amp is runing at 1.33ohms or 1.34 something to that. So firing them back towards doors and how do i figure out tuning. I have built a box before for 2 15'' hx2 powers that was approx 9.6 cubes before. I think I can build another one. Just how do I figure out tuning. Think if I built a bigger box I can add some more db's?
