Major differences in sound? what do u prefer? ie. RE se15.....SS rlp-15

aluminum cones have a higher tendancy for buckling.

Just to clarify....

The Rl-p's do not have a problem with their cones buckling.

But of: "Aluminum cone vs paper cone"...

But then again, what quality woofer with an aluminum cone has had a problem with buckling?

Pulp paper has one of the best weight to strength ratios of any common material used on speaker cones. Better than aluminum. But that is not to say an aluminum coned sub cannot be designed to perform as well, or better. There are much bigger, more important factors that dictate a driver's over all performance than just its cone material.

Okay - the concern about aluminum cones buckling....that's news to me.

Should I be worried about my M6? It hasn't shown any signs of giving me problems but now you guys have got me all paranoid...

Any well and consciously designed woofer with an aluminum cone will not suffer any problems. The subwoofer was designed to perform optimally with that cone, and was thorougly tested prior to being put into production.

Nick's comments were more of a "comparison"....Paper tends to have higher strength. He wasn't saying that everybody with an aluminum cone woofer should worry about their cones buckling.

Aluminum cones are a very good heatsink- designed well , attributes to great frequency response, efficiency, durability, and power capacity over 'paper'

i've fed my rl-p as much as 2500wrms from a orion 2500d (rated, of course) in a ported enclosure..

never even seen the rl-p come close to buckling....

u'd have to get some cheap *** aluminum cone sub or be feeding one tremendous amounts of power to achieve what nick mentioned.....

not saying it can't happen....but if a system, and it's equipment are designed properly, then that shouldn't be an issue...

and +1 on what audioholic and steve said as well...

Seriosuly? LOL

I was simply stating the primary differences between the two materials as used in recent (3-5 years) history. Of the two materials, pulp > alum for strength *IN GENERAL*. Other then that, the rest of the driver is optimized around the given material.

I forgot which forum I was posting on.

Power capacity is not a woofer attribute. It's an enclosure / environment attribute.

Besides, everyone knows the most important part of a woofer is the bling factor

Duh
