Speakers Hacked into a Little Black Back Pack

Accessories

By: Andreas Ødegård on September 16, 2009 10:15 AM

Portable speakers can be very nice little accessories to carry around, but the "little" part often extends to the sound as well. Forum member Dobson did his own thing and instead put speakers in a backpack.

Dubbed the "sound bag" by its creator, this thing is quite impressive with 2 large speakers powered by a 50W amplifier that runs off a 7000mAh battery, which gives the rig a battery life of about 15-20 hours. This will definitely play louder than anything even an army of normal portable speakers can spit out and might not be too bus-friendly, but it definitely has style. Great work!

Are those regular 6 1/2" speakers? That's a great use for them I should have thought of that!

What kind of amp is it?
Try a Class T amp if you got money laying around - they're efficient + small

Yes that's 6.5" speaker, amp is TDA1554 chip. And battery life is about 30 - 60 hours on normal, easy listening sound, 15 - 20h is on high volume, on full volume (you don't want to near bag then) maybe 2 - 4 hours.

Phonak Audéo PFE

Phonak Audéo PFE offer outstanding clarity and precision; natural, dynamic mids and treble, and decent bass for a single armature in-ear phone. They handle dense, complex music very well. The PFE work well with most acoustic and some electronic music genres, but bassheads might have to look at other alternatives. They're great for sports as well, since they fit very securely.
