DC-93 Posted April 18 Share Posted April 18 Curious about my 2Ce Signature II speakers... How can two woofers work without interfering with each other? Thanks for any insight. (2Ce photo below from the site) 1 Link to comment Share on other sites More sharing options...
Richard Vandersteen Posted April 18 Share Posted April 18 All the Two's, Three's and Treo Series use this system but how it works is a secret. You own one of them and can comment on how well it works. RV 2 Link to comment Share on other sites More sharing options...
DC-93 Posted April 18 Author Share Posted April 18 I'll take a stab at it- The 10" woofer is tuned lower by the mass weight on the cone. The polyfill soaks up a vast majority of the back wave of both woofers. Clearly, they can play deep in a room. 👍 I repair vintage speakers and use a 30 hz tone to center voice coils. My Signatures can easily play the tone, whereas a lot of woofers installed in their cabinets just have some cone movement with nothing audible.

I recommend you just enjoy the music. RV 2 2 Link to comment Share on other sites More sharing options...

With a 5” blade, sharpened at 14 degrees to a mirror finish on my ceramic stones. 😉. I enjoyed my music while stabbing. Link to comment Share on other sites More sharing options...

B Elon garners some polarization, (p’rolly like a vandersteen speaker.) I’m not sure he personally trained them, and also not sure he really cares about the IP. The state of pollution there (From what the TV shows it as) seems like it rivals SoCal before the NOx reduction, so it is p’rolly a good thing in total for them to be doing EVs.) 1 Link to comment Share on other sites More sharing options...

A joke until we have a Carbon/NOx free electricity grid to charge them with! RV 1 Link to comment Share on other sites More sharing options...

RV Two points: Larger engines usually have a better brake specific fuel consumption… so assuming no losses on the grid it is better from a total enters perspective to centralise it. The larger facilities are typically running high boost and running lean, which also decreases NOx. And it is easier to have a larger catalytic converter if it does not need to be in a vehicle. But yes, you are correct. One still looks woke in a Prius or Tesla though, and social signalling is a thing. 1 Link to comment Share on other sites More sharing options...
ctsooner Posted April 30 Share Posted April 30 Great stuff. My only politics with my music is listening g to my politics of choice through my system. NPR AND Fox News both sound equal through the system. The tuner is an olde Luxman from the 70,s lol 2 Link to comment Share on other sites More sharing options...
BFW Posted May 1 Share Posted May 1 From a “well to wheel” perspective battery electric vehicles produce less emissions than internal combustion vehicles. BEVs are NOT zero emissions but significantly better than ICE vehicles. Link to comment Share on other sites More sharing options...

From raw material to EV vehicle through recycled material after use energy, emissions and toxic waste EV vehicles have a more significant impact. Where this pollution/waste is deposited or emitted is more portable. Our home and factory are solar including two Tesla batteries $$$$$$$$$$ at home and it is a real eyeopener how inefficient solar panels/batteries are as our system won't power our home from sundown to sunup! Just did this (always investigating something interesting) so I would know what I'm talking about with experience. RV 2 Link to comment Share on other sites More sharing options...
GdnrBob Posted May 1 Share Posted May 1 Congrats Mr. V. on using solar. It is a relatively new technology, and, I believe will be improved upon with better tech and materials. -Kinda like digital audio, don't you think? 😉 Bob 1 Link to comment Share on other sites More sharing options...

DC-93 Posted May 21 Author Share Posted May 21 Back to my original question... I figure the trapezoid shaped bass enclosure combined with the polyfill stuffing gets rid of any back waves. I forgot the shape of the bass cabinet is most important. 👍 1 Link to comment Share on other sites More sharing options...
