Morphenspectra Subwoofer Box, Passenger Footwell Type Options

[Allan]

I just got my new subwoofer enclosure from James, but have a question.

Who has one, and how did you secure it in the footwell?

Btw, I highly recommend it if you're wanting bigger sounds in the car... (IMG:style_emoticons/default/smile.gif)

I have heard of a new "flat" sub woofer. Anybody using them?

smallest i've seen is a 10". too big from the box morph makes, not enough cubic inches.

Make a taller and larger dia. ring spacer. Port the encloser to reliever preasure

and get movement on coil.

This is very bad advice and it's much more complicated than just trying to get the cone to move more. Boxes are tuned to a certain extent, and ported enclosures require very specific volumes and port sizes to match the drivers specifications. Like someone else said, ported boxes are normally much larger in size than sealed enclosures too, so to get the correct size for the woofer you're using you'd eat up way too much space in the 914's foot well.

A small sealed enclosure is less efficient than a ported enclosure, but the other benefits far outweigh the benefits of a louder, peaky ported or bandpass enclosure. A sealed box has a much flatter frequency response curve that sounds much more natural and isn't nearly as picky about the enclosure size in regards to the drivers specs. To get the sealed box louder, just add more power. Really. Oh, and ported enclosures really are only louder at certain frequencies. They're great for rap music if you want to tune the box for 808-like bass drum frequencies. (IMG:style_emoticons/default/smile.gif)

I'm generalizing a bit, as there are very high end audio systems that use ported enclosures. It's even possible to get a rather flat response curve. However, this isn't likely to happen in the passenger foot well of your 914. And you're really going to do nothing but hurt the sound by sticking a random sized port into a sealed box.

My four cents,
