I have a Gear4 Portable Duo Speaker which includes a Dock for I Pod / I Phone.It also has a detachable front with strong metal for portable use.It's in excellent condition with hardly any use.It has 38 total speaker output.18w satellite speaker output,20w subwoofer and delivers true high-fidelity audio quality.It will also come with an 18v charger and lead from headphone jack to the speaker so music can be transferred from any portable device.I will also supply a 8GB I Pod,BUT THERE IS A FAULT WITH THE I POD.SOON HAS IT COMES OF THE SPEAKER IT DIES SO I ASSUME THERE IS A PROBLEM WITH THE BATTERY,BUT YOU CAN TRANSFER MUSIC TO IT FROM ANY DEVICE WHEN CONNECTED BY LEAD AND IT WILL PLAY ON THE SPEAKER AND WHILST PORTABLE SO IT HAS IT'S USE.
If you would like any more details then please let me now.
