Sneak Peak

[galacticmonkey]

Noticeably louder... His van is crazy loud, but mine is definately a little over his right now as it sits. When everything gets working correctly and we can finally turn the volume up, it should be flat out insane.

[Charger]

Wow that's insane. I wish I could get a demo. I'd sit in the vented chamber

[dblover]

what amps your using?

[w87will]

what amps your using?

Yeah, 24 Ascendant Audio Chaos 15s on 6 Sundown SAZ-3000Ds in a 4th Order Bandpass.

Wow. Your explorer? I think it was an explorer....amazed me! This just makes me speechless. Awesome. Waiting for vids and more pics

[AI James]

hes using sundowns 3000d's

[fourlug]

Not exactly sure what happened.... Must have dropped the pallet or someting.

Its not able to change the tuning. Its tuned at 47hz, so it should play everything pretty well.

Do you have then entire freq response? How low you figure it will play? lookin awesome btw!!

[galacticmonkey]

Yeah, plays everything pretty well. Havent played too much on it yet though, just tests to see if we can figure out that amp.

As for my Expedition.... This setup is so much louder its almost comical. Makes those 4 18s sound like 2 12s. Blasting this one if I look down I can actually see my nose shaking.

Not sure on what number it will burp... Mike is going to bring in his TL one of these days and were going to do a peak score just for fun. He said that it sounds like a car that could pull a 160. Im not going to make any predictions though, anything in the 157+ range and Ill be happy with the number. As it is Im happy with the loudness, and its only just began.

When we get everything figured out so we can actually turn the volume past 1/2 way (havent been much past it yet) things will start to get loud.

i cant wait to see vids of this beast i hope you get tha bugs worked out real soon

[galacticmonkey]

Now we're thinking it might just be voltage... Dont even have my alt in and havent charged the batteries. So thats the guess for now. Going to put it on a real slow charge and let it soak it up for a while and see how that works.

So If thats the problem, it explains all the "symptoms". I guess that one amp starts clipping out from the voltage (dropping to like 11.2) and shutting off. That would explain that, and also why the subs are barely moving, since if the voltage is sooo low, they wouldnt be getting as much power.

The more we keep playin it, the louder it keeps on getting. As it keeps loosening up, its just getting rediculous. With a full charge its going to be insane. Eventually when I step it up to 16v.... Yeah.

Ummm.....

"One characteristic of bandpass enclosures which is universal is that they exert greater control over cone motion over a wider frequency band than conventional designs. Due to controlled, rapidly changing air pressure on either side of the woofer, the woofer is capable of producing high levels of acoustic output without physically moving very much. This means that the woofer is less likely to encounter excursion limits in the main part of the sub-bass range. However, just because the cone isn't moving as much doesn't mean that the speaker's motor assembly isn't still trying to drive the cone hard; it just means that the speaker cone is encountering resistance to motion. This resistance can be very hard on speakers, especially when crazy car audiophiles are at the controls. The conflict between the force generated by the motor assembly and the air pressure in the enclosure can impose extreme stress on the glue joints and suspensions of the woofers. You can literally tear a speaker apart in a bandpass enclosure if you apply too much power."

Hopefully the guy that built the enclosure understands this.

Looks crazy though, I hope it doesn't tear itself apart long enough to make some cool vids and get it metered.
