robot underground?

[donpisto 5,000+ posts]

This is a quote from Steven Kephart on another forum (he's a former Adire employee, so he's familiar with the Brahma);
"Just so you know, the Robot Underground subs are far from the original Brahma performance. They use a much longer coil which completely eliminates the XBL^2 motor topology, creating more of an evenhung motor. This means that BL will be very peaky (Madonna's proven peaky isn't good ), distortion will be higher, and linear excursion will be much lower. "

I would never buy one.

If you were interested particularly in a Brahma, I'd check out Exodus' "-X" subwoofer line-up. They use an updated version of the Brahma motor and are considerably more cost effective than the hack-job Brahma's sold by RU.

This from the12volt.com? I've spoken to him on that forum a couple times, not sure what other forums he may be on, just curious.

opinions on robot underground hard times anyone?

Just a heads up, when you go direct, you get a free cast frame upgrade. We're building more this week.

this is true i talked to pat from robot underground about this. the length of the voice coil affects the xbl^2 techongly, make the subs nothing near a brahma. but pat says he talked to someone from adhire that said using a long voice coil instead of the oem vc will only increase spl. cough ******** cough.

I think Dan Wiggins is a great source for answers on that subject... Which is where we got the parts and information. Kephart is just pissed that I posted his vid on YouTube.

Wrency says:
Remember kids that your amp, especially a class D mono block amp will run full power into a 2 ohm load even though its 1ohm stable or states that it produces full power into a 1ohm load.. I know, this goes against what everyone says, but it's true. Simply adjust the gain properly to the 2ohm load and PRESTO, full power. If you want more info on this please email, robotunderground@yahoo.com Remember that an amp is simply a gain device. Signal in plus whatever +db gain the amp can do = output.

One of the funniest things I have read in quite a while...lol
