Hi sifu, currently im using altec lansing mx6021 but can't be power on already. so any speaker similar to it? im interested in edifier r1850DB but the dept of the speaker a bit too long for my desk so i searched for logitech z623. but logitech z623 doesn't have tweeter on it and i read review they said its just a loud speaker. so im lost now i also have headphones audio technica ath-m50x but the bass a bit lacking.

hey everyone, looking to replace my mx6021, whats the different between rt1700bt and r1800t iii and how does it compare to mx6021? the r1800t is cheaper though.
