But he specifically asked about the relationship of SIZE and WEIGHT to performance.

So a 4 tesla neo motor will be SMALLER than a 4 tesla ceramic motor. Correct?

Meaning, you can't judge a motor/sub on it's size and weight alone.

the point was not that there would be no change in size or weight (in fact, i have said from the beginning that there would be). the point was that using one material over another does not make it "better/stronger" as you had said.

anyways...

so in a nut shell you can't judge the sub by it's magnet size or weight ?

thanks for all the info...you guys hold down some serious speaker talks.

So where exactly did I say that using one material over another makes it better/stronger?

I said that the materials used has more to do with performance than the size of the magnet.

If you'd just read what I said instead of trying to make up some sort of false argument then we could get somewhere. I *think* we're both saying the same thing at the end, just our ways of saying it are different.

Size does matter but as posted so does quality not to mention overall motor design..... also consider that magnets (especially ferrite)don't like heat and may degrade over time.....

How does a sub with these specs look ?

Peak power handling: 800 Watts

Continuous power handling: 400 Watts

Impedance: Available in Dual coil 4 ohm (2x4 Ohm) or Dual coil 2 Ohm (2x2 Ohm)

3" black anodized Aluminum voice coil former with Kapton layered protection

210 -oz magnet structure

FEA (Finite Element Analysis)

Computer-optimized aluminum basket

Extra large dual Progressive Nomex spider for maximum and ultra linear excursion

High-density 1.25" wide big foam surround

Ultra Rigid/seamless aluminum cone

Rubber-Toughen isolated high current Tinsel lead wire

Patent pending Cartridge Snap Terminal with selector plugs

Unique 2-piece Aluminum frame

210 oz magnet structure sounds pretty good for a 400 watt woofer. The Finite Element Analysis is also a good thing to ensure you get equal levels of linear excursion in each direction.

what sub is it you are looking at ?

xxPunk0Ramaxx

i would rather see some detailed t/s parameters.

are there many companies that don't use FEA anymore?

Good if real

Good if real

Fine, depends on how you want to hook it up

Almost all subs use Kapton.

How much is Magnet, and how much is just iron?

This has been around for decades.

Computer optimized for what? Reduced Cost? Fastest
manufacturing? Almoste everthing is done by computer today!

Fancy words, but does it work?

Fancy words, what is the linear Xmax?

OK, but many cone materials work fine.

Good

OK, so fancy connectors. What is Patented? the manufacturing process, or something that really improves performance? Good connectors have been around for about 100 years.

Why is it Unique? Is it better than a one piece frame?

See you must read these marketing descriptions with some skeptisizm.

Im with Jordy on this one. Yes there is quality properties involved in magnets. Not just strength. Punk you cant believe that pyramid and JL use the same quality magnets. Magnet will degrade with time, better ones will have very little loss of power, and cheap ones depending on what they have put into it (chemically speaking) will lose power.
