no, no, no, no, no, no, no....they will not produce a square wave unless you send the a clipped signal.

when you hear someone talking about "square wave" is does mean the wave propagates in a 'square'.

A square wave would be a clipped wave. This will be a distorted sound.

ALL subs can (should) create a normal sine-waves if sent a clean signal. But your waves in a pond analogy has not bareing then it comes to speakers.

You have to look into the way the sub is designed...L7's are not good SQ subs, but SQ is subjective. Some people may actually like the way L7's sound (most of the time these people are new to the 12-volt world and all they think is "if its loud it sounds good")

Yes L7's can get loud but they are unable to reproduce sounds as accuratly as other subs in their power and price class. L7 coils have high inductance...this hurts them in the SQ field.

A square wave reffers to a clipped signal when an amplifier is being overdriven, weather it is because the resistence ohm load is too low, or the volume is too high.

A sound wave is curved on a graph, therefore people think it is round, but it is actually "SPHERICAL". The sound desipates in all directions, not just forward. It is not as true off axis as it is on, but they are definetly spherical.

A square shaped speaker will still emit spherical sound waves just as a round speaker. Just take a square piece of MDF and drop it on the sidewalk and listen to it facing it. Now repeat the same as you face away from it. Now repeat the same as you are arround the corner. can you still hear it? Yes, of course you can hear it. You see, th eshape of the object doesnt change the sound wave form. It may change the sound wave frequency, but not the "form".

Now do the same with a round piece of MDF. You will notice that the round will sound different, but it will still have curved sound waves. If you record both of them and look at them on a graph, you will understand the similarities, and differences.

trick question.

sound isn't a "wave" per se. it's compression and rarefication of air. regardless of the driver's shape, the air is still compressed and rarefied in the same manner.

Hey, Marshall...I noticed that you stated the L7's can't produce sounds as nice as others in it's class, price and/or power. If that's the case, what would you recommend?

I would recommend not hijacking someone's thread, and starting your own on the subject :-)
