i hv a sonic gear bt3 and a altec lansing vs4121.

sonice gear bt3 - DONT EVER BUY, it sucks after 1 year. the wire got cacated need twist and hold it at the position then only can work normally.

altec vs4121 - got it a few days back. DAMN IT bought wrong speaker d. but nvm bought d so wat to do, the sound quality is NICE and GENG. actually,I wanted to add a double bass and 2 extra speaker. but realise tht cannot put, cuz they use different wiring. (i tot all speakers wiring are the same)
