  1. hey J4, i want answers for diff kinds of subs...like i mentioned in my post above! does positioning of drivers / ports on a sub has any impact on its output?? if it does, then there hav to be diff positions for the sub placements too....wut say??
  2. hi CECAA850....i really didnt get wut u meant in ur reply! sorry, its kinda woolly up there.. wut i feel is this (.... n its just my imagination! ) - for ported bass-reflex subs, the actual effect comes from the port (i say so, coz i hav seen subs with speaker drivers inside the enclosure, with only the port opening outside!) n from wut i hav learnt in these forums - 1. the port uses the air driven by the 'backward' movement of the driver 2. a in-out phase switch inverts the driver movement. so where the driver would normally move out, itll move in; when the phase is changed by 180° for the same signal....thus changing the direction of bass comin from a bass-reflex sub (in my case, opposite directions, since the ports r at the rear....) now, in my speaker setup, the sub drivers face a hollow wooden cabinet n the ports face a solid concrete wall....did this setup aid in improvin bass on changin phase from 'in' to 'out'??? lemme know....
  3. hey sivadselim, dont mind...but i hav a humble setup! Altec Lansing 641 speaker system - subwoofer with two 16.5 cm front-firing, long-throw drivers operating at 109 Watts@4 ohms@10% THD@16-105Hz(-3dB) Single Channel Loaded (92 Watts@4 ohms@1% THD@18-100Hz(-3dB) Single Channel Loaded); with two bass-reflex ports at the rear. the sub's in a corner with the ports facing a wall, 0.5 m away and the drivers facing a hollow wooden cabinet, 0.45 m away....so the walls & the cabinet engulf a C-shaped enclosure for the sub! the sub has a 'subwoofer phase' in-out switch....for a long time, it was in the "in" position...the bass then used to boom/muddle for few audio passages, which i disliked. i changed the sub position throughout my 5 m x 4 m room; but the 'C' corner still sounded the best! finally, i turned the subwoofer phase switch to "out"...the bass came out wonderfully tight, well-defined & distinctively clear for the same audio passages, which earlier sounded boomy/muddy!! i want to know what exactly happened?? can you investigate? Thanks...
  4. sorry for the revival of thread...but i wanna know how does a phase switch work if the sub has 2 drivers? thnx!
  5. hey guys, how do u place a subwoofer in a 5m x 6m room for the following cases.... 1. front-firing driver with rear bass-reflex port 2. front-firing driver with front bass-reflex port 3. front-firing driver with side bass-reflex port 4. dual side-firing drivers with bass-reflex port 5. down-firing driver with bass-reflex port any answers??
  6. thnx guys!!! all of u.....for all the info! the last question...why do all the latest speakers hav inverted dust caps? they sure look good...but do they make good sound??? wutsay?!
  7. few questions!! 1. what's the function of a dust cap in a speaker? does it have any effect on the speaker performance? 2. over time, i have seen many dust caps 'crumpling'....they get flattened out! does it mean the speaker's damaged?? 3. why are the latest speakers fitted with 'inverted' dust caps? are they better?? plz help me know this! thnx!!
