Busking / portable battery powered speakers

Post by DS-10 Dominator » Thu Mar 04, 2010 1:40 pm

I was reading about the DS-10 picnic stories by Cardiac Trance and saw pictures of the Roland Mobile Cube



Harmony Central: http://reviews.harmony-central.com/revi ... +Cube/10/1

Seems pretty cool.

Any experiences with this one?

Or others like the ion Block Rocker...

or the ion Tail Gater

It's a pity these ion devices are mono, could give phasing problems when using stereo effects. Well, you could pan everything to one side....

the cube is pretty sweet. nearly bought one for summer busking sessions. instead i bought a really clean and loud local (korean) made amp that has pretty decent build quality and runs well off a 9v.

don't worry about the mono output, it is all summed and the speakers would not have enough spread to give phase issues. try a few out at a local music or guitar shop. your ears will know what you want

In theory there are phasing problems to that too. Left +1 and Right -1 stereo becomes 0 mono.

But in practice I guess it wouldn't be that audible.

if the left channel and right channel are out of phase then when it is bounced down or folded in a mix then there are some serious issues. it is all about the time of arrival. material that is not in sync will go berserk and kill people at random!

i remember back at a university live gig. we created a pocket of out of phase material by angling flipped out speakers into a corner and it made a little space (a somewhat quieter space) of barely audible aliased type sounds. very cool experiment.

it was also better than hearing the horrible "music" that was being performed

haha i nearly picked up the mobile cube too! but it seemed too small/good to be true.

the video review demonstrates some pretty nasty clipping though - has this been a huge deal to anybody who owns one, in practice?

I tried the ion Tail Gater a minute. It has a tweeter and a woofer. Like I said it has mono output, but it sounded pretty good, and loud! Not bad for about €/$ 150. It has an ipod dock,RCA and Jack connectors. Still considering it...

The great pixelh8 busking



at the end you hear the live sound, don't think this thing produces any bass

He uses Marshall MS-4 : http://www.marshallamps.com/product.asp ... and%20MS-4

If you wanted to go down a slightly diy route you could probably mod a cheap guitar amp to accept battery power. This shouldn't be too difficult because beyond the transformer and rectifier stage of the power supply the mains voltage is turned from AC to DC (batterys are DC) to power the electronics.

So if you could find the right point on the circuit board and measure the voltage you should be able to substitute it with the right battery voltage from there. I'm thinking a small (atleast not car battery size) lead acid battery about the size that go in burglar alarms would do it.

I've got a cheapo amp that i might have a go with when i get time. :geek:

This could be done with any boom box that has an 1/8 inch aux in line.

Yes, there are tonnes of options. Most portable stereo loudspeaker devices have an aux in of some kind.

I ended up buying the smaller stereo Roland amp. It's pretty loud IMO but it was pricey

I have the Ion Tail gater, perfect device, really loud. 2 x RCA, 1 x iPod, 2 Mic inputs, all usable simultaneously is a win!

I have two batter-powered Roland Amps: The Bass Micro RX, and the Micro Cube (for guitar). I highly recommend them (they have some effects built in, as well.
