I found this,through searching on youtube for 12v systems. Then I saw bikeology.net, and then Ians. http://img86.imageshack.us/img86/3073/ontheroadgj3.jpg http://www.zenatode.org.uk/ian/activism/pedals.xhtml Efficiency,efficiency efficiency! Efficient amps, efficient drivers, creative use of things! I enjoyed this,from both a non staged/no acting viewpoint, and due to the extensive knowledge of the guy in blue shirt - Ive used the same winisd program. Using a Paudio complete horn is one option for midrange,another is a conical horn with an 8" or similar.

Very informative and entertaining at the same time. I'd be very very appreciative if someone could volley me some info over about the compression driver/horn and the tweeters (watts,ohm, wiring) as the footage ends when it comes to be explained. Thanks a lot though for all what's there. Big up pedals!!!!!!! GoOd gOoD GOOD...

Thanks a lot!!! JoeCeeDee 2011-03-29 19:39:05 2011-03-29 19:39:05 4 3 4.00
