First enclosure construction

[Matthew Bibby]

Hello, I am completely new to the world of speaker construction etc.. and so require some help.

My first project will be a sub woofer box for the boot of my car, after that I will add to it, but for the moment I will just be making the sub. I wish to use 2 x Skytronic 902.222 12" 300W drivers as I am on a limited budget and have found these at a reasonable price.

The specs of this driver are as follows:
Power max:300W
Power rms:150W
Voice Coil:6.25 cm (2.5")
Diameter:30cm (12.0")
Frequency response:20Hz - 6kHz
Magnet weight:1.4kg (50oz)
SPL @ 1W/1m:91dB
Re:7.1 Ohms
Fs:29 Hz
Qms:1.62
Qes:0.71
Qts:0.53
Sd:346 Cm2
Vas:49 litres
Cms:288
Mms:59g

I assume that when putting 2 drivers in one enclosure you add the relavant specs of the two drivers together, in this case the same drivers, when entering them into enclosure calculators etc?

Finally, could someone recommend the best enclosure size calculator to use as some I have seen are quite confusing.

Welcome!

Yes you at correct about the enclosure size for dual drivers as opposed to a single driver. Whatever size enclosure is needed for the single driver you just double it for duals, triple it for three etc. I have only done sores building projects so my experience is very limited, I couldn't recommend a enclosure calculator. Jinjuku & Annunaki are both very knowledgable on these things so hopefully they chime in. Try the DIY section here on AH I think they hang out there a lot if I'm not mistaken.

Enjoy the build!!!.....Oh & post a lot of pics once you have enough posts here!!

Thanks timoteo, I will repost my question in the section you advised. Thank you for answering my question about enclosure size. I will defiantly be posting pictures of my progress once I get going.
