Line Release Technology?
« on: June 25, 2015, 09:15:43 am »

CSW claims to have invented a way to limit the excursion of a driver so that it does not exceed xmech.  Does anyone know how this works?  I have been dreaming of a way to make a speaker that can protect itself.

Its called horn loading and a high pass filter!

There is another manufacturer who says they designed the cabinet (with front loaded woofers) so that the drivers would not reach excursion limits.

It is called "using a small amplifier"--------------

Peak voltage limiting and correct HPF?  It is not necessary to reinvent the wheel.

I just hope this kind of stuff doesn't become the marketing equal of "unity", for which I could ritually disembowel Mackie's marketing staff.

No I mean the transducer opens the circuit if the excursion exceeds 3".

So the sound stops?

That doesn't sound like a good idea.

Some people would notice--------------

I would much rather have it compressed than stopped.

put a normally closed lever type microswitch with a roller on the tip against the cone. set so when the cone moves out a certain amout the switch opens. as soon as the cone moves back it closes the switch.

I went to the Canadian Sound Works website and found nothing like that. However, I could not refrain from posting that I would be horribly embarrassed if I published that I used "Russian Burch" (sic) to construct my speakers.

(It is one thing to misspell a word when posting on a website, quite another trying to look like a business marketing a product, instead of a parody. Maybe people without my thousands of hours of proofreading don't even notice it, but typo's just jump off the screen and slap me upside my face.)
 :o

Edit: Google found 5 examples (by Russians writing in English), so apparently non-English speakers spell it that way.
