[QUOTE="squeak9798, post: 651114, member: 555320"] Deep; yes. Loud; no. I'm a picture kinda guy [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] So here, look at this: [URL="http://www.imagedynamicsusa.com/website/tech/data_sheet_max12v3d4.html"]http://www.imagedynamicsusa.com/website/tech/data_sheet_max12v3d4.html[/URL] Notice how the red line (the line that represents that sub in an IB alignment) is lower than the other two lines (sealed and ported). Those lines represent output across the frequency spectrum. The higher the line is, the higher the decibel level of the output. Between 20hz and 60hz, the IB setup simply has less output. But, there are things to consider other than overall otuput. But moral of the story, if you are a basshead, IB probably isn't for you. It's not hard to build a box and toss it in your trunk. IB requires you to find a place to mount a baffle (or find a pre-existing space) large enough to mount the sub on, and then you need to seal that baffle area up so that the backwave and frontwave are isolated. It's simply a lot more work, and not something that will work well in every car (hatchbacks and SUV's for example). For example purposes yes, that would be right. [/QUOTE]
