Description of Patent Types

Im following you, and i agree that people tend to push their subs too hard. RMS ratings are too often seen as a minimum power requirement, and has helped to popularize the notion that 'underpowering' your subs is a bad thing.
Yes, you could eliminate the spiders, if your moving mass was zero. We are saying the same thing...

Weeeeee

I'm not trying to sound like a know it all but I have a idea on how to completely elimate the spider but it's going to rake some aerious pecersion and special circuitry in the Amos to work..

The typos make it hard to understand exactly what you just said, but if you have a legit way to eliminate spiders, I bow down to your intellect. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I read the original replies from Scott about the patents, and I might be remembering wrong, but Id remembered it as he purchased the patents to all the sizes except the 18". Like I said, I may be remembering wrong by now though, and Im too lazy to try and find those posts by him.

It's so easy in concept you would say **** why didn't I think about that..Key is to keep the mass perfectly linear in stroke..

This reply seems to indicate you are only talking about coil rock, lateral motion. But the spiders also help with linear damping.. transitioning from the cone moving one direction, to moving the other. Unless Im not following you exactly.

Yes I'm talking about coil rock..

I dont claim to be an expert on speaker design, but it would seem to me that eliminating coil rock is an easier accomplishment than is controlling the vertical motion (damping) of the moving mass. This is especially true with subwoofers which only cycle 100 times a second or so, which linear bearings could withstand. Its mids and tweets, which cycle thousands of times a second, that would make traditional bearings impossible to implement. Its always occurred to me that speaker designers dont use bearings, even on subs, because spiders combat both vertical and lateral motion relatively effectively. I suppose it would also take a hell of a bearing to withstand even 100 cycles a second for any reasonable lifespan.

You've piqued my interest. But if you dont want to discuss your idea here, I certainly understand.

Sorry op

Op I'm sorry man I didn't mean to hijack..

It's so hard to get any decent tech talk now n days I got excited..

Btw I know those drivers are going to pound..

Btw they loook freakin sick..

I'm jelious..
