I cannot decide between 2 12w6v2's or 2 10w6v2's. I listen to rock mostly, but i love to bump once in a while (i know, nothing surprising). So, has anyone done this comparison before? how much louder do the 12's get and how much SQ do i gain from the 10's? Unfortunately, I cannot listen to both and it seems its different for every car install. But I was hoping for some general comparisons to help me make my decision. ANY help will be great.
Well im not an super audio man like some of these guys here but from what I understand it.. the bigger the woofer the lower the tone it can play. Its really not about loudness its about the tone. Like a 15" sub can play bass that is at a much lower frequency than lets say a 10" sub .. but the 10" sub plays the higher frequency bass better because its smaller. This is how I understand the size on subs though I could be wrong just my expience with listening to systems.
A speaker basically is an air piston....When voltage (signal) arives at the woofer, it pushes outward (typically) and pushes the air in front of it, then as it comes back to rest, it pushes air off the back side of the speaker...As more wattage is pushed through the speaker, it will move farther and produce more pressure....Volume is measured in db's. The louder... the more db's (of sound pressure)....Given the size of the piston (speaker) the more area to push the air, the more air gets moved.....12" speaker will push more air than the 10" speaker (louder) as to how much more I am not sure...There may be a chart somewhere..... Just remember, a sound pressure increase of 6db will sound to you to be twice as loud....Typically if you give 100 watts to a sub, you have to push 200 watts to that same sub to see an increase of 6db... If you push the 10" or 12" with the identical amp, you will see an increase in volume, but I am not sure how much....Look at the freq response charts for the speakers you are talking about....The 12' should reproduce lower freq better than the 10"......You should look at a chart and understand it...Just because a speaker is rated for a response of 10hz-250hz.....Does not mean you will hear all of that (at least not at the same volume across that curve, a chart will show you that...keep in mind 6 db sounds twice as loud)...

Bigger speakers do make lower notes.....sometimes......depending on the sub, the box and the vehicle.... Had a buddy who bought two 12" subs in a box (cannot remember what brand)......I had my one JL audio 10" in a box I had built......With a test disc and SPL meter, I checked the response in his vehicle and I also checked the response in mine.....His actually had more output in the mid bass (100-250hz) than mine..Mine had more output in the 20-40hz range....To listen to both systems, his moved more air and appeared to hit harder...Both with about the same power amp-wise....SQ?....Mine walked all over his.... This is the prime reason why a very cheap sub usually is not as good as a well made quality one.... In the case of this example, both are JL audio...The 12" should go lower than the 10"....... Willy
I know a little bit about JL.. and the W6's are nice nice subs. But in reality. all you need is a 10inch. I'd recomend the H.O. Box from JL. GREAT sound. And it'll get loud enough to impress the friends. Quick tight bass - If you have the money though why not try a w7? an 8inch will also do the trick. H.O. Box
There is actually a way to figure out maximum SPL in the vehicle...All the times I did it, I was usually within 2 dB of the actual outcome...up tp about 150 dB......Yes, this is true and i aint full of shyte!!!!!!!!!!
