View Full Version : About the Exodus Anarchy...

I recently had a parasitic resonance develop in my door panel so I took it off to address the issue. The Anarchy is a pretty potent driver. One thing I've noticed lately is talk of needing a big amplifier for these to compensate for the fact that they are 8ohm drivers. It occurred to me that I should post a video of mine running off of a Sony XM-450G. For those unfamiliar, it's a four channel rated to do 50w/ch at 4ohm. Two channels for the Anarchys, two channels for my 3/4" Vifa tweets. The first video is solely the midbass drivers and their output, no subwoofer. Toward the end of the first horribly recorded video, you can hear a frequency that isn't as strong as the rest... this is where my sub comes in. The subwoofer is in use for the second horribly recorded video. I'm truly sorry for the awful quality but you will get the idea if you put on a good pair of bottom-heavy headphones.

Very efficient lil drivers, they definitely dont need a ton of power to get them singing... folks just cant stand the idea that they dont need to tax their electrical system to get nice front stage lol. I'm a fan of the anarchy, 1 @ 30net per on 100rms per would convince many you had a substantially larger sub setup if one was to run them as the bottom octave supply. People cant read tsp's anymore my man... and have no idea what to expect from looking at all those numbers and abbreviations lol. According to most people the tsp's are useless and dont even matter anymore.

Yeah, these things are great. Just trying to help those who are thinking that 8ohm drivers are a no-no or that they need gobs of power. I mean, when I cross these high and apply more volume knob(80Hz@18dB/oct), my ears give out before these drivers do. And that's still off that Sony. In the future I will likely build enclosures as many have done, and throw my Nakamichi amps on the new front stage. Planning on 40Hz to 400Hz coming in underneath a set of Aura wideband drivers in the pillars. For now, this temp SQ setup is what it is.

10" LMS on a US Acoustics 2300F, by the way. Feels nice. :)

Right on, I've got tsp's i pulled from them here somewhere. good bl:mms, low le, good q figures, good sensitivity, good x parameters etc. how you liking a single lms 10 sub stage? i just switched from dual 10" to single 12" and I'm liking the swap. <17hz without issue!

Having total control over time alignment, EQ, and crossover points/slopes via the 800PRS helps. It shakes the steering wheel and all that fun stuff but I plan to scale things up, soon.

Don't be afraid to cross these over much higher than that. Also you have a good bit more travel out of those little guys than you're using with that little amp.

Much more left in these, this is just how they're setup for now. Some days I run them without a filter and cut the sub, some days I highpass them @ 50Hz and some days @ 80Hz. Depends on how loud I want it or how real I want it to sound. The Sony works them to full stroke with ease but it leaves a little to be desired for warmth and control when pushed really hard, which is to be expected in that scenario (less than 50w). In the near future the Auras will be on a Zed Nakamichi PA-502 and the Anarchys will get a Zed Nak PA-1002. I may even get crazy and double up on the Anarchy drivers as I like to cross very low.

As far as crossing them high, I've been very pleased running them as high as 2k as long as it was a steep filter. That won't be necessary pretty soon as the Auras are more than able to cover 400Hz and up. I'd rather avoid crossing in the 1k-3K region altogether, it pays dividends when extracting all the spacial information in good recordings.

They also offer 4ohms now

They also offer 4ohms nowWhich is definitely a smart move. I just thought I would post some real-world evidence that low power on an 8ohm driver will still provide pretty decent results. Mainly for the guys with this mental block.

Yeah they are very efficient and 12 mm of xmax each way ain't too bad either:veryhapp:

lol, been on caco much lately? Ever since SD and Skar hit the scene saying they didnt and the hordes of huggers started replicating the gesture it has turned into a misinformed epidemic :(

Haven't really looked at CACO since Ant bought it.

maybe 1 of 40 there even consider them relevant to the driver. Apparently you only have to throw sd parts into a frame and motor to get a winner lol. Its like audio sects worse than ever. Sundown, AB, tantric, Skar, Obsidian, or "other' lol

Considering what passes for sounding "good" to most folks that might as well all be true.

No mud with these drivers.
