I have been using Edifier M3400 as speaker for my TV. I have a LG 32" LCD TV connected to satellite TV system.
In the beginning (without Edifier M3400), the sound isn't really good. Lack bass and thin sounding (normal for standard TV).
I wanted a budget solution for the problem but don't want a full AV system. I had a 5.1 AV system but it's too clunky and too many cables. (I throw them away after the AV amp malfunctioned).
I wanted something simple and straight forward. I went to the IT hypermarket and tested many budget 2.1 PC speakers and found that Edifier M3400 2.1 Speaker System is a good bargain. It offer clear clean high and mid range with solid deep bass. The wooden satellite speakers looks great beside the LCD TV.
I bought it and plugged it into my TV (RCA out port). Instantly, watching TV become much more enjoyable. Voice become clearer and larger. Sound effect is louder and best of all, there is good bass. I can hear the beat and punch of TV programs that I could not hear from my TV own speakers.
I also connected my Kworld Media Player to the TV. So both satellite TV and media player are connected to the Edifier M3400 through my TV RCA out (line out) and I can enjoy good sound from both.
Do not compare this to a full AV system though. This is merely a budget (USD 70) solution to improve TV sound while using less space. This solution is good for smaller living room only ( I suggest apartment with less then 1000 sq. ft.). Don't expect this to shake a bungalow :-).
Edifier M3400 is even better on PC as you site closer to the speakers. Good gaming sound too.
There you go, I'm enjoying Movies, Discovery and History channel now with clean sound and good bass.
p.s. Edifier M3400 may be phased out in many places. I bet Edifier P3080 can do the job as well ;-)
Here's my setup.
Additional note :
- The M3400 doesn't have wireless remote control. You need to use volume control of your satellite TV decoder or TV to control the volume via their wireless remote control.
- If your TV or satellite TV decoder can't control volume of Line out / RCA output, you may want to choose Lotitech Z Cinema (picture below) with wireless remote instead. Else, you have to manually control volume on the speaker.
- Your wife or girlfriend will appreciate this as they like simple TV set up. Easy for them to enjoy their favourite TV show. They care less about what AV or hi fi system you have, especially it need 4 remote controls to operate.
To connect TV to PC speaker, you need add an RCA to 3.5mm jack (connector) as below:-
