Gentlemen, I'll apologize now.. I've searched but come up short.. I'm sure it's in here somewhere but I'm not finding it...
I want to learn how to read subwoofer specifications / specs ????
Some I know and understand, many I don't.. I do have basic audio electronics knowledge in areas of impedence, ohm's law, etc.. but it gets fuzzy after that.
Since I see many of the specs on a lot of diy drivers other than just larger subs, I figure it's time I learned.
Please point me to it or where I can understand all these.. Here's an example of the
DIYMA 12" sub I'm currently high-bidder....
# Recommended for sealed box only, from: 0.25 cft. to 1 cft.
# For SQ use, 0.5 cubic feet for a butterworth (.707 QTC) alignment
# Maximum thermal powerhandling: 1000 watts with typical music
# Mechanical powerhandling depends on box and program material.
# If you hear any noise, turn down the volume to avoid damage.
# Single 4 ohm voice coil
# QTS: .354 //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
# FS: 25hz
# VAS: 41.7 L //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
# RE: 3.6 Ohm
# BL: 22 //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
# SPL: 84.3 dbwm
# Le: 1.3mh //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif no clue
# Xmax: 23mm 1 way (71% bl, 25% cms)
# Xmech: 64mm peak to peak
# Weight: 37 lbs
# Cutout diameter: 28cm
# Mounting depth: 16cm
# Driver volume: .15 cft
the enclosure?
... Again, I apologize, if this is covered in some sticky somewhere or a website.. please just point me to it. Just hoping to learn something today so I'm not reading "french" when seeing sub specs posted.
I might add it would be useful to know which are more important and what range should a guy stay in for "SQ subs" as they're called in car audio.. "Accurate, quick, strong" are the kind of terms I would like the sub to be described as.
