15"s compared to 10"s in speed bass. is the myth true?

[Nighthawk1192 10+ year member]

I've been hearing from friends that 10"s respond faster than 15"s for double bass. is it true? and can 15"s reach the freqs a 10" can? is it noticable?

as in 15"s getting the higher freqs as well as 10"s

Your friends are liars. lol A 15" will play just as fast as a 10". If you give it a 40hz signal it's not going to play 35hz or something.

How a sub performs is pretty much 1/4 sub 3/4 enclosure. You can make a 10 sloppier and a 15 hit very tight and accurate just by how you design and build the enclosure.

Friends shouldn't give car audio advice

i guess not. Sonicelectronix said something along the same lines. they said that bigger motors have a harder time slowing down the cone. i just want to know if its worth getting a SA 15" over a SA 10" because i listen to quite a bit of alternative rock and metal.

get either and build a box thats designed to have "punchier" bass. but back to the myth a hz is a hz whether its an 8 or a 18.

Transient response is not really about the size of the motor, it has more to do with the inductance of the voice coil itself from what I have understood. The box also plays a huge role.

Audioholic has explained it really well in older threads that are related to this topic.

Unless your friends are professionals in the car audio field, ignore anything they say.

The "myth" has alot of truth to it. Subs have different cone mass, FS, motor strength, etc. Depending on the sub, you can tune it however you want, and it still wont play how you want it. Now, say youre using high quality equipment, yea you can pretty much make the sub sound however you want, but not all subs will hit the low lows or be very responsive, no matter what you do.

Now you're talking about different subs, we're talking about the same sub just different sizes. Fs doesn't play a big role unless you are doing infinite baffle, as the sub is tested free air. When you put it in an enclosure the environment and how the sub responds changes. I'm using a sub meant for SPL with an Fs of 42, in a box tuned to 31hz in about a full cube above the suggested size, and it's not sloppy nor does it have a hard time hitting the lows.
