Portable Sound System (Prototyping Stage)

Self made 4.0 sound system. With a pair of 4-inches mid speakers capable of delivering max output of 200Watt, and a pair of tweeter for the hi. No Bass speakers were used. The whole amplifier system can be powered up by any 9-12V DC sources. 6xAAA's batteries will do fine. Max output of the amplifier system can be up to 40Watt. Not bad for a portable sound system yeah...

Specifications:
Input power: 9-12Volt, Max 5000Ah
Output power: 50Watt Max
Weight: 900grams
Sound system: Mid & Hi Only. No Bass

i came across this vid a few times, and i was wondering the specific details of that battery you have?

is it a small compact recargable one that lasts a fair while?

@shanoracing

I used 8x AA size battery to power it up. Max volume can last about 90-120 minutes. I am thinking of getting those 12V battery pack thou.

[KZPwned]

how did you made them?

[manwest]

I built it with a amplifier circuit, with a 12V battery supply, and a set of speaker capable to delivering 200Watt of output. If you want I can send you the circuit diagram of it :)

[johny260]

wow. could I get a circuit diagram too?

[Fuckingalien33]

@manwest and the amplifier what sound delivers?

[AlienwareGamerM11x]

these are sickk :O can you make a vid of how you made the circuit board?? please?? :P

[chajdak1]

[jayholley123]

could u send me a diagramm of it plz ?

[Imprezaman555]

[12vinny95]

@MrPulamea

Yupz. I realised it has too much high frequency volume. Now I am trying to do the other one with adjustable Mid and Tweat. And a higher output power too.

@edmundasgiknius nice , too much tweats though . my room speakers are 250w bass and 30w tweat each and I still think the tweat is to much ...
