Whats the Difference in Subwoofer sizes?

Most people will tell you big subs are "slow" and don't reproduce "quick" bass very well, while smaller subs are "quick", but don't go as low.

That's really not true at all.

I guess by "vibration" you're meaning SPL (loudness).

Generally a sub with larger diameter will have more potential to play loud, but a smaller sub with more cone travel could make up the difference.

Yes a good 10 in a good enclosure can play low. But an equally good 12 or 15 in an equally good box will play as low or lower and with more output.

Smaller subs are cheaper mainly because they're smaller - less material, less weight, just cheaper and easier to produce.

And a lot of good 10's are WAY more expensive than not so good 12's and 15's.

The other negative of a big sub is that getting the most out of them requires a larger, more expensive box, and generally a more expensive and more powerful amp.

N2Audio said it great. the sizes are also a option on car size. I have a Convertible RX7 with a small trunk with 2 10" from a old I had and it is way to over powering with a cheap amp going with 2 8's with a new set up soon. The sizing of the subs should depend on the size of vehicle that it is installed in. 12to 15 should be in SUVs for the best sound because the sub need to push air by volume like a great 10" set up would drown in a SUV where 12 or 15's would do justice. The same with the 12 or 15 in a small car would not hit right cause it is muffled. I hope that help with what was said by N2Audio!!!

nicely there is distinct distinction between a 8" and a fifteen". the favourite of a sub playes a large area in the performance besides. What it boils all the way down to is the bigger the sub the bigger the day vacation their for the more advantageous air it strikes. The more advantageous air that strikes the more advantageous Bass you experience. an 8" sub with a a million a million/2" voice coil with a a million" day vacation received't move close to as a lot air as a fifteen" with a three" voice coil and three " day vacation.
