Forevrbumpn Posted May 18, 2009 Report Share Posted May 18, 2009 Actually you can tune a sealed box, you just need a speaker tester like the WT3 tester, and loading a sub in different size airspace enclosures will yield different Peak, and roll off slopes. I' am actually messing with that in the past few days. I have a 18" sub with a 13.5hz Fs in a 1.7cf sealed box, and when tested, hooked up to the tester you see the new "system" peak, which in my case is 54hz, yet rolls off in the 20hz range, even though the peak is so high, its plays really flat below the peak tuning In a 3cf box, that drops down to like 35hz I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

I heard four of these sealed @ 600 watts a piece in a cr-v & they pounded. so i was originally going to seal them in my truck, then i got the idea to port it.

Lowroll Posted May 21, 2009 Author Report Share Posted May 21, 2009 Okay, So i decidied to just seal it. I was going to partially recess the amps into the box but i decided to scrap that and build a center console to mount them in. It moves me from street to modified but its all good. I got some pics of what i got done tonight. id like to see what you guys think, and how do you think it will do on the meter? ill have 3.9 cubes before displacement. Took off the partial front panel Got the panel cut to fit and 2 holes cut Got the front panel on I cant wait to hear these things. Space is a little tight Current System: Pioneer 6900 HU Front Stage: (for now) Soundstream tarantula 5.25 in the doors Soundstream tarantula 4x6 in the dash Kenwood 400.4 for mids & highs Bass: 4 Soundstream RW-12's 2 Power Acoustik Stax 4000/1D's single chamber box, 2.65 cubes.

Lowroll Posted May 28, 2009 Author Report Share Posted May 28, 2009 So iv gotten some more work done in the last few nights. I was supposed to have started my console by now but my local shop has got me all screwed up, so im now looking for new amps. Im looking at the power acoustik Stax 4000/1D or the MB Quart DSC 2000.1D discus. Im going to need 2 of either one. What do you guys think of these amps? if i choose the stax ill have 4400 watts. Right now the box is getting bondo'd & sanded. Ill throw more pics up later. im getting excited to hear these mama-jamas Current System: Pioneer 6900 HU Front Stage: (for now) Soundstream tarantula 5.25 in the doors Soundstream tarantula 4x6 in the dash Kenwood 400.4 for mids & highs Bass: 4 Soundstream RW-12's 2 Power Acoustik Stax 4000/1D's single chamber box, 2.65 cubes.

svman Posted May 28, 2009 Report Share Posted May 28, 2009 if he wanted a ported box could he have put the port/s on the very top facing the roof? Link to comment Share on other sites More sharing options...
Lowroll Posted May 28, 2009 Author Report Share Posted May 28, 2009 well, im like 6'1 & i have some el camino bucket seats in it. My current box is ported and they are facing up on the top of the box. This box however was just the wrong size to port and the fq would have been way high.
