QUOTE(monodevil @ Nov 17 2009, 04:58 PM) but someone told me that we have to connect an active subwoofer only.. Actually, I think many 2.1 systems for PC do have an active subwoofer. That's why it has its own power cord.the standalone amp cant connect with passive subwoofer (like many 2.1 system for pc)  |

QUOTE(monodevil @ Nov 17 2009, 05:40 PM) he said that if u buy an avr like vsx 818/819.. u need active sub.. Yours is an active sub, but the important part is whether it can accept the signal from the AVR sub pre-out. Which I will discuss below...so i told him i already have pc's subwoofer with 2 small speaker (sonic gear brand) and have its own power cord.. he said that its not active sub.. Added on November 17, 2009, 6:17 pm QUOTE(chiakwang @ Nov 17 2009, 06:09 PM) I am confuse......... Hahahah............ Yours is also an active sub. The tricky part for any 2.1 PC audio system is how to connect it to your AVR. Normally you connect to a PC using a single 3.5mm stereo jack. The signal coming from your PC is actually a 2 channel signal. If you use an AVR, I assume the cable connection will be:The Altec Lansing MX-5021 subwoofer comes with built in amp. 240V is connected to the Subwoofer. The volume/bass/treble control is also connected to the Subwoofer. From the Subwoofer again, it outputs to both speakers. The Subwoofer is rated at 50W and the speakers are rated at 20W each.... So, is this active or pasive amp?? Am I able to buy an amp and utilize these speakers and save some money? (a) from the AVR sub pre-out to the sub - this is normally using RCA connector, so you might need some kind of adapter because your sub probably takes a 3.5mm jack. (b) from the AVR front speaker terminals to your 2 satellite speakers - I see the MX-5021 has got spring terminals so you can use your own cables. Issue is whether your speakers can handle the power from the AVR. You can experiment with the connections, I think it is connectable but I have no idea how it sounds or if there are any other issues.

QUOTE Thats mean it carries the risk of exploding my 20W speakers..... Is it......???? Only if you turn volume up too much. Your PC speakers will have a power rating, if you pump in more power than it can handle then the driver can malfunction. QUOTE My friend tried playing bluray converted transformer dvd using his cheap 5.1 system and it sound much much better than my 2.1 system. This makes me want to buy a 5.1 system and match it with bluray..... Maybe the difference with your friend's 5.1 system is the extra surround effects and dedicated center channel. Added on November 18, 2009, 1:55 pm QUOTE(chiakwang @ Nov 17 2009, 11:11 PM) So, whats the estimated costs of a decent home theater system with stand-alone amp and speakers? I've seen a Jamo 5.1 speaker set at Harvey Norman for about 1.9k. Dunno how good it is though, didn't have a chance to demo it. The AVR will be another 1.8 - 2k.Added on November 18, 2009, 2:04 pm QUOTE(chiakwang @ Nov 17 2009, 11:11 PM) Besides, whats is the cheapest available bargain that we could get for the lowest end pioneer HTiB?
