That was my experience with my speakers tho :/ I guess it's different with everybody. I can see how .5 makes closer to 20hz much cleaner. I did like that aspect. Double kick was much cleaner too.
So you like the typical roll off? then either learn to appreciate "flat" sound or build for ".707"

With cars, you have to remember there is MASSIVE cabin gain and its highly unpredictable.

So picking a Q and aiming for it won't help you unless you know what sounds good in your particular car and to your own ear.

with a decent sub, .8 should be good in most cars. they SAY .707 is good for home, but it really isn't considering room gain doesnt start till 30 Hz, and even then, it doesnt stack much.

I had an 18" woofer in a 21 cubic foot box tuned to 12.5 Hz with an 8" wide port, 36.5" long....

That... was the cleanest sub I've ever heard. My current setup is that same 18" sub re-coned in a 7 cubic foot box with two 18" passive radiators.

Doesn't even compare in terms of sound quality but its much less of an eyesore.

Then again, going from a coffin sized sub to a washing machine sized sub isn't much of an improvement.

It does weigh around 220 lbs when fully loaded though. Can you spell resonance-free?

But to the point, horrible sound quality relative to the coffin sub.
