once u buy the r1280db and you'll learn more about speakers and audio and you'll soon crave to upgrade

i also started with r1280db
not bad to start with these

big rooms= more space for bass to develop

its about physics already so i dunno how to explain clearly

6.5 inch for s3000pro sudah mantap

ya... lower bass, longer wavelength, bigger room required
if not, before a single wavelength is formed, already bounce back from the wall

"Also, bass notes have a long wavelength, some exceeding 20 feet, so a 25hz note might not even create a single wavelength before it bounces off the rear wall and back on to itself." from some audio forum

fark although studying physics too but i also abit blur on this matter la.... but u prolly wont even listen down to 20+hz pun
usually 40 hz liddat nia
