[QUOTE="Babs, post: 3066755, member: 567066"] 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 [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] # FS: 25hz # VAS: 41.7 L [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] # RE: 3.6 Ohm # BL: 22 [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] # SPL: 84.3 dbwm # Le: 1.3mh [IMG]//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif[/IMG] 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. [/QUOTE]
