Bump4life Posted August 12, 2012 Report Share Posted August 12, 2012 What's the difference in a sub with 1 or 2 magnets and a sub with 3 magnets? do you mean like single stack, double stack and triple stack? if so, it is form function. it is all part of the engineering of the speaker. there is a certain amount of magnetic force required and whichever way is most cost effective or best performance is how they cut the magnet pieces. it has to do with throw of speaker, and a lot of variables that make the speaker go round Quote Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

HHR Ed Posted August 13, 2012 Report Share Posted August 13, 2012 Has to do with the geometry of the woofer design and how all the parts work together. For instance, you may have a 200w rms woofer with a single slug. This is because at 200w, the woofer will only move a small amount. So adding more slugs would be a waste of money. A larger woofer that handles 1500w rms can have 2 or 3 slugs. This depends on how thick the top plate is and how tall the coil is. Also what design are they using. A SQ woofer will be underhung with a short coil and does not need as much depth in the gap as a SPL or ground pounding woofer. So woofers also use a bump in the backplate to add depth. Sometimes though, another slug is added to increase motor strength but this has shown to not help much. A good top plate and pole piece design can be the most effective when coming down to motor strength.
