Ive been into car audio for a while now, Ive designed and built several systems for myself and friends. My last sub was a simple sealed box for two 12" Alumapro's. I haven't even carpeted yet, but it sounds real nice hooked up to a Zapco Z50C2. Cleanest bass Ive heard. (although Im partial to my own design
) I've only done a little bit with fiberglass and other slick fabrication methods, but I plan on starting something next summer.
I haven't done much with home systems , but for my first project Id like to build a set of pro audio monitors, or a passive radiated sub.
Those speakers you built sound sick!!! What did you use for components?

I think this is a great hobby to have. With your knowledge of speaker design, you'll be able to build yourself an ass-kicking setup in your own home for a fraction of what you'd pay retail......... and you'll have fun doing it.
Car audio is fun. Maybe I'm getting old though, I usually just prefer quiet when I'm driving around.
On my big cabinets.............
Tweeters: Morel MDT 37's (horn loaded, fabric dome)
Mid: Focal 5K4411's
Bass: Dayton 12" (I forget model)
each driver has about a 92 dB efficiency on it's own, and overall they retain about a 92 dB efficiency, which is pretty good I think. I had Madisound make the crossovers for me.
I have a 4th order Linkwitz Reilly crossover on Mid-tweet, and a 2nd order bass to mid. The dayton's have about 2.5 cu ft. of dedicated volume space, the focal's have about 400 cm each. While a lot of guys these days are running with MTM's for Left/Center/Right home theater set ups, I still like the 3-way setup a lot better for straight audio purposes. you really hear the difference on, for example, a tight punchy bass drum.
On the audio side, I drive these with a Crown 800 CSL power amp (300watts/channel 8 ohms).
The REST of each cabinet is dedicated volume space (over 9 cu ft) for 15" McCauley 6142's pro audio drivers..... Their ultra low frequency 15" They're not even listed on their web site, they're a custom modification to their 6242's that they make for movie theater applications. The cabinets are ported, and the f3 approaches 21 Hz.........
All wood is 1" mdf, and finished with a nice REAL cherry veneer. Big as they are, they're beautiful to look at. I built a small frame to attach speaker grille cloth to, that plugs into the face of each cabinet.
I drive these with a Crown Power Tech 3, which is 760 watts a side into 4 ohms.

I use a Behringer active crossover between the 2, and usually crossover around 50-55 Hz.
Yes, they DO POUND, heh
The nice thing about the McCauleys is that they're still very musical for the audio side. And they handle a lot of power. Spec wise, they're very similar to JBL pro audio drivers, but are considerably less expensive.
With the size of the cabinets (like most things in life, you know that to get deep bass out of a speaker, size DOES matter

I get really low bass sounds on any decent dvd movie sound track. If I turn it up a bit, it's enough to shake the couch. When I first planned out my system, I considered making some tactile transducers. But I don't need them
So I tend to like movies like the Matrix, or the Lord of the Rings trilogy not only because they're great movies, but because of the quality of the audio sound track as well. Although to Warner Home Video's shame, the 2 Matrix movies were released in 5.1 not 6.1....... boo hiss.
