TH & Unity Horn - Solar sound system

So an update.....

After buying a Pulse 4 x 300 and getting it shipped from the UK we now have 8ch`s of power for the system BUT we now know we will definitly need a mid bass driver adding. This is because the Unities only really go down to 250 efficiently, after that they fall of very quickly. So we need something to cover the 90 - 300 range and are investigating what will fit the best...2 x 10" with rear ported back to the horn or 2 x 12" with only a FLH??? It will also be easier to build a whole new box with a larger flare to cover the low extension we`re looking for as well. It`s boiling down to some hornres predictions versus whats available in Aus...!!

So it also means we need to free up more amp channels and the obvious path was passive crossovers for the mid / highs. The mids naturally roll off from around 1k and after a bit more phase and freq testing we reckoned we wouldn`t need a LPF on them. So a simple design which fits neatly into the exisiting boxes was come up with . The adjustable Lpad allows us to match mid/ high ratios better for different venues.




So after fitting a prototype crossover the other day we tested the response which was all a bit horrible till we remembered it was a 2nd order and that we had to flip the phase ..DOH! And we got this trace straight away with no mucking about....pretty damn good ...!




So all coming together nicely.....which leads us onto this monstrosity which is being fitted to the trailer this weekend...say hello to 800 watts of windy power!

What happened to this in the end Phil?

What a project!

Project is def` still ongoing! Just walked in at midnight from day 3 of fitting that wind turbine and other trailer / system mods.

We have the main stage to do at a little Eco Festy this weekend near Melbourne so it`s flat out prep!

More pics and vids to follow!

foldable beds?

yep was probably the bed frames. Look much tidier now!

I did something similar with a battery once but managed to knock the offending item off the terminal before it welded itself to the metal frame and killed the battery. A dead short on big batteries is frightening stuff, it's easy to get 1000a+. A mechanic I used to use once got his wedding ring and spanner to short a battery and nearly lost his finger when the ring melted in a split second.

Be carefull of the vibrations and oscilations from the wind turbine; they can get pretty violent in the right conditions so make sure you don't get fatigue cracks in your welds.
