Dorm room sub ver. 3 wtf lol

[PV Audio 5,000+ posts]

Okay y'all, I'm now onto my third dorm sub. Here was the first:

Two TangBand 5.25" subs off 70w plate amp. Problems with this one:

1. Nowhere near enough output.

2. Amp was running at 2 ohms, making it hard to play different kinds of music without having to adjust the gain (overexcursion wasn't a possibility, it was a matter of how much //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif ).

3. Too large for the room.

No pictures of the second one, but here's the design anyway:

Problems with this one:

1. Again, too small Vb for the driver (wait and see!), too large for the room.

2. The ****ing jigsaw broke when cutting out the amp hole, so I cut it 2" too tall for some genius reason, which meant that I had to put in a 2" strip of wood in the hole (unglued and all!), and seal it not with silicone, but mighty duct tape //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

3. Too boomy anyway, aka, couldn't play harmonic bass notes at high volume without running shit together

Now, on to the new one! This uses the same driver and amplifier, but is a completely different alignment //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

So, let's see, what do we have here?

Hmm? What's that screw in the middle of the side for?

Let's see if we can find out by looking at the front. Hmm, doesn't look like it.

A peek inside you say? BAM! Full 1/2 chamber bracing mother****ers //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

What gets this honor, eh? How about a driver from my favorite company?

Yep, there it is. Dayton 12" HF subwoofer.

What shall power this mother? Why not a digital amplifier?

I peeked under her skirt for you electronics pervs out there.

All cut on my fantastic new 60t titanium blade.

I'll audition this tomorrow, and if I don't get some clean, accurate bass, I'ma be pretty **** pissed. //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

What are y'all running in the dorms? Don't even bother posting ballstothewall. You'll just make us all feel bad. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

.75 cubic feet is WAY too small for that. I'd even say that a 1 in front of it would be too small. Give it 2.5 at that tuning to be really hittin the notes. These subs don't like to be choked up, as I found out switching from a 3 cube box to a 2 cube one to put in the dorm. Completely different behavior.
edit: Take that back. That's the HO, so 2 cubes should be perfect for it.

Design?

Hows the Bash amp? Does it put out close to rated power?

 

[PV Audio 5,000+ posts]

Yeah man, it's pretty solid. Could use a bit more headroom though, so I might get the 500w instead.

Im thinking about doing one of the Parts express projects...Maybe the Tri Trix...and upgrading to better drivers.
