You guys are getting mixed up with terms, they will play the SAME frequencies, the only difference is the volume at which those frequencies are reproduced, that does not mean one size has "better low-end extension" than the other.

It just means one will have more low-end output over the other, all size subs can usually plya the same frequencies as stated above.

yeh i guess we did mix up terms and understanding lol...i meant to say that an 8 will have a harder time being loud in low freq compared to a 15

That must be why in the world of home audio, there are 4" speakers that play clean and linear down in the 40's. 8's don't have a harder time if the enclosure is right. On a retro note, back in the day a friend of mine had 18 RE8's that peaked 32 hz and did 153's on the headrest. Displacement (NOT cone area) is required to get more amplitude from a lower frequency in many conditions. So, it is very possible three 8's could have the same SPL at the same frequency as a single 15 if all drivers had similar stroke in a similarly tuned enclosure.

i stand corrected...**pulls foot out of mouth**
