All of the above, bro.

Thanks!

Hey man, post up those graphs...they show exactly why my boxes sound so damn good in these cars.

Big fat peak at 50Hz with a mellow drop down to 0db at about 80...let the cars acoustics do their thing below 50 or so.

As always... wealth of information in here. Loving it. Keep up the good work gentlemen.

I, like you, opted for a sealed enclosure (custom built ~1.2ft^3) with more power for as good an SQ as I could get. It sounds really clean on all forms of music (important to me since I have a VERY wide taste). I'm sure it could benefit from some form of active Xover setup, but I am pretty pleased with it as is.

I also run a 12" Luke box in my wife's car, and it sounds awesome as well. I prefer my 12" sealed box in my turbo car, but I am pushing 5 times the power to a much more expensive sub and amp setup. Luke's box is the best compromise of Power/$$$ to SQ I have been able to find. I hope he continues to build these sort of boxes and offer them to the community. His box saved me mucho time and $$$ in doing my wife's car and she couldn't be more pleased.

Just gotta get the ability to do waterfall plots...but no mic, no PC card, no high dollar software, just a beat up old man with a tabelsaw and a calculator from the dollar store.
