… Annoying the neighbours!

This soundsystem has the same ported enclosure but to improve the output I have added an electronic cross over and Bi-amped the system to give a total of 40W of skateboard mounted noise! The system is powered from either a 12v internal battery (small and light with about 2 hours play time at full volume) or an external battery pack for longer skate session.

Here is a shot mid wiring that shows the two amps and the rear of the drivers. I have used spray foam to fill the backs of the top end pizeo horns to stop the heavy bass rattling the plastic. The enclosure is made from 15mm solid cedar, glued, screwed and filleted with epoxy to withstand the abuse it will see while skating. I have tuned the enclosure to have a little bit of a bass boost around 80-100 Hz to give this more punch when in an out door environment.

Currently I have a very basic preamp that has a line in, high and low gain, the ablitly to change the roll off of both the high and low outputs, a battry meter and very high quality volume pot. Over the next few weeks I want to add a few different line in jacks, audio source selector, Mic in, Headphone out, bass and treble control, mono/ stereo switch, about 6 light to show power to the amps and xover and to the fault warning from the amps and two very sexy blue vu panel meters!
