Duct tape ans SPL

Same. I want to get to where my beard goes ape **** sitting there. Once I get my money for my B2s... And that Viking 7k... And all the batteries and wires... Well ****. Why did I pick such an expensive hobby?

I had a Viking 7k. Good amp

Anyways, back to the original topic, I am going to try some tape. I cut one hole a little too big so there is some noticeable air leaking when I'm pounding. I'll definitely report back if there's even a slight audible difference in my case

Thanks! I might try sealing with caulk instead

Well, not much, if any improvement on the duck tape. Meter might say something different, but I doubt it more than a couple tenths. Also, your new sig... Yes. Just yes.

Which one? Gay pride or Spidermonkey?

Changed it back anyways

I enjoyed the gay pride one, but the spidermonkey one was absolute gold.

Found that pic and had to add a caption with Spidermonkey in it, lol

This is the impedance profile of a vented enclosure. The two impedance peaks represent port and driver resonance. The *height* of the peaks represent losses. Anything you can do to minimize the losses and/or increase damping will result in a lower peak, more power and more SPL.



Dis be de math and shit.

Thanks! I thought the peaks in impedance were also peaks in efficiency //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

They are, but the efficiency you gain from resonance you lose because a constant voltage amp makes less power at a rate more or less in direct relation to the efficiency gains. This is why an impedance peak that looks like that doesn't sound like that.

Then wouldn't lowering those peaks just stress your amp/electrical more?

Throw a curve ball to you here since you said this is a daily and not chasing tenths... consider fill.

I hope you all realize that tweaking to pick up a dB at the meter with duct tape, PVC pipe half-rounds, etc. will be inaudible for you or passengers. For more impressive demo, figure out which door or window open makes it feel more intense in the passenger seat. Those sort of things can actually be audible, the vast majority of tricks on that thread won't help for just having your music louder.

Not to mention that looks fkin ghetto. no way I would roll with my sh*t looking like that.

Should I cover the inside of my box with polyester foam instead?

I was going to resin everything and then wax it. I thought resin/wax or bed liner were the best options.

What's your opinion? Any experience with polyester foam on the inside of the box?
