New Mach 5 Build - Zero Power Compression

[bose301s 5,000+ posts]

Is the goal SQ or SPL? Also, it is impossible to eliminate power compression, current running through a resistive element creates heat, always. Thus that coil will still heat and power compression will occur, it just maybe lower than most.

I would guess a coil that size should be able to handle on the order of 6kw //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

I want to see the motor that thing is going in to !

inherit problem of larger coils is more moving mass. I don't know how you're going to solve that slight issue unless you make the cone out of kleenex //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

All you need to overcome that though is enough motor strength.

Reminds me of some antenna loading coils I've used //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

well of course I was stretching the reality of it with my statement //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I would hope by now you'd know better //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

They looked pretty sweet

The surround is sexy the cone and dust cap remind me of the diamond drivers

Be sure to check out the videos of those Acoupower drivers.

Yeah, they were pretty sweet. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The difference with mine is it won't have a basket. This was something I was working on a number of months ago but ended up throwing in the corner to set up the assembly line.

Now with a big lathe on the way, its time to come back to this.

When you say no basket, this driver comes to mind. See the third pic in the ad.
