Anarchy/Dayton TM build

any idea when we can expect your build?

Sent him a PM. Thank you for linking this. I look forward to your build.

Side note, I have an acct over there but can't reply to the post. grr.

Thanks for the update. I really enjoy your builds.

I got him via PM PI. TY!

Now I've seen those drivers I can't wait to see what you have planned for the cabs.
Your Curvomatic kit is going in the post today. www.curvomatic.com

Popcorn is in the microwave, just need to hit 'Start'.

Will Rick put up a page on his website for these? Sounds like a GREAT TM, with some good power handling. Great for a smaller HT.

JSS

I wonder if Exodus would do some sort of discount for us as well? That would be sweet. I missed the initial Gb they did. I like the possibility of an MTM version as well.

Awesome concept, can't wait to see what you do with this. I'm guessing the RS28F is going to have to be padded down about 10 dB but the power handling should be quite decent. Depending on the alignment the Anarchy can take well over 100W (not sure what the thermal limits are).

You might want to double-up or tripple-up the resistors in the L-pad for power handling purposes, and then hook these up to 200+ W amp to see what they can do.

"Good tip on doubling or tripling up on the resistors to make sure they can handle the wattage."

for some, this will be very confusing. the idea is to use more and/or higher power resistors that provide the same net resistance as the stock model.

if one just doubles or triples the same resistors, the whole crossover will change.

Yeah sorry. So if you had say a 10 ohm resistor that is rated for 10 watts, you could instead substitute 3 30 ohm resistors in parallel to equal a net resistance of 10 ohms, but giving you 3x the power handling.

It's basic circuit stuff, and most people know about that, but some don't.

I'm not sure if you ever need to do this with anything other than Resistors though.

As far as construction details go, what material will you be making the sides out of? I'm guessing the overall dimensions of this speaker are going to be ~9 x 12 x 16", am I close? Anxious to see how you do this, as I am in the planning phase of my own curved speaker build.

I don't know if anyone is interested but I just measured one of my Anarchy woofers and here are the T/S params:

Fs = 46.43
Qes = 0.46
Qms = 7.627
Qts = 0.424
Vas = 19.7 L (which is wildly different that the published 9.61 which leads me to believe that it is a typo on the web site since all the other values are close)
Re = 6.321
Le = 1.438
SPL = 88.21

This is on a brand new, not broken in driver. YMMV

I had asked Kevin about that VAS measurement and he said to go with his value, not the one I calculated. I'll ask Rick what his measurement was.

Rick didn't measure the VAS.

Let me clarify. Before I tested the woofer I looked at the Voice Coil magazine measurements. I used their parameters as a starting point and chose a test box based on my experience with woofers of similar size. I then did nearfield testing and summed the output of the woofer and port.

With a nearfield measurement being large signal it's more accurate than a simple T/S set of parameters. In this case I think it's even more important because the Xbl motor's inductance changes quite a bit over excursion. Looking at your parameters I would say that my box volume and tuning matches them very well.

Sorry for my late reply. I didn't put up a page on my site because it was my understanding that the woofer was no longer in production. I have been told there might be a 4-ohm version available; however, that would dictate a new crossover design.

He is still selling the 8 ohm version because I just bought 2 of them.

Since I don't get Voice Coil magazine, was it Vance who worked with this driver?

Yes
