I respectfully submit that materials DO matter. Metal cones can and do ring and have harsher break-up than (conventional) treated paper. This said, there are excellent metal performers -- the "21" Seas are amongst the best. Best,
Metal speakers. How are they?
I notice that aluminum and magnesium cones have become very common, including in some high quality systems. What's the story on these things? I am considering purchase of a speaker that has Seas 7-inch magnesium woofers, in MTM configuration.
These speakers will replace Dynaudio Gemini MTM speakers whose little 5" woofers are great, but just won't keep up with my three MG1.6 + SW front speakers. I have contemplated rear subwoofers, but there just is not space. The Dynaudios were used for many years as the high end of a biamped system, and they were fine for that purpose.

Sorry Eldartford, I missed yr question. I meant the frequency where cone break-up occurs. That doesn't seem an issue in your case as you can easily play the seas in its optimum range, crossing to the tweet above that. Mr Linkwitz's site is, indeed, a mine of info. OTOH, if you're interested in a passive dipole implementation using a seas magnesium mid, check out the Point75. That site has is a mine of information for diy -- probably the best quick-reference site around. Cheers |
