Default help with driver specs

I inherited two 15" subs from my son's car system and wanted to try to use them in my DIY home theater. I plan on building my own box(s) but haven't been able to use any design software because I don't know any of the driver specs.
What I do know:
4 ohm, 310 watt max, 15" 30 ounce (magnet)
They are called Y2K Titan and have a sphinx logo on the driver.
Any help locating the info or, at least, some insight on how to proceed sans the info would be greatly appreciated.

Hi,
I couldn't find anything on google but that seems like a very small magnet for a sub. That likely means a high Q. That means a big box. You might want to consider building them into the walls or ceiling.

If you have basic tools, you can measure the specs.

Thanks, I tried that too. I have plenty of room for a big box though.

Cal,
Sorry about that short reply.
I have heard about the wall or ceiling option before and was wondering how (or if) that is any more effective than just taking a wild guess and building a box. Other than the time and materials of course.

I have the multimeter. are you aware of anything for the pc that would work as a sig gen?

I would find the specs first, then we can work on a design.

For a quick and easy signal gen I use WinISD. Jost open a project, then set the signal generator to get the frequency from cursor. Now click and drag with the mouse. This method lets you quickly dial in the resonance frequency by measuring current.

Thank you Simon5 and the others for the helpful links and software !!!
I am an absolute beginner with the urge to learn more and more (I wish I had more time...though)

A little bit off-topic maybe:
The tone generator that you recommend is simply great tool, but I have a question: Every tool that I use for tone generation makes a buzzy sound when I put values from 19700-21000 Hz, through my Audigy 2 6.1 ? Is this a fault of my soundcard or all the soundcards that are available? It would be easy to come up with the opinion that this HF included in cds is making the sound playback dirtier...Is that true? What should I do?

Thanks in advance guys...
