Mod TV speakers?

I have been thinking of replacing the speakers in my Mitsubishi big screen for some time...

I think it uses a 5.25-6.5 inch woofer and a 1.5-2.0 inch paper tweeter.

I think i remember the manual said something like 40-50 watts? per channel.

I would like to add a cheap powered sub to this as well.

Just take the speaker level outputs from the board and rout them to a terminal block on the back of the set and use the speaker level inputs of the sub and send the higher frequencies back to a decent set of component speakers in the TV.

This way i wont have to use the stereo as often to just watch TV.

any suggestions on a cheap powered sub that sounds decent as i would also like to add on in my master bedroom to compliment the 6.5 in-wall speakers.

TIA,

Jonathon

    Yeah, forget it. Instead, find a way to hook up 2.1 powered computer speakers.

    Dont really care about warranty, as it has already expired.

    I dont want to add additional speakers to the room, i have plenty of room in the front pannel of the TV.

    OK, then try it. Keep in mind the replacement speakers should be as close to the specs of the original speakers as possible. If not, it'll sound terrible unless you manipulate the crossover or perhaps bypass the crossover altogether and use full range speakers (???). Not sure, but feel free to experiment and report your results.

    I'm interested because I posed the same question on this forum a couple of weeks ago and the best answer was to use computer speakers. The main problem was a lack of a remote for the volume.

    I doubt very seriously if your TV puts out 40-50 wpc and I doubt that replacing the speakers will improve anything significantly. Get a cheap reciever and a coupla satellites and put them on top of the TV. I got a great little satellite/sub system on Ubid years ago. 3 satellites and a powered sub for about $120. If you can find the Advent B2R system it makes a nice little upgrade for a TV that you don't want to make into a full-blown HT. Sounds very nice for music too.

    Correct, my TV has 10 watts per channel, but you are missing the point, i have thousands of dollars worth of components in a rack right next to the tv but i dont want to be putting hours on them just to watch jay leno...

    even 10 watts per channel is plenty to drive an aftermarket component system with a powered sub at normal TV viewing levels.

    This is going to take about an hour of research to figure out how the tv speakers are wired as they have different speaker leads going to the bass and tweeter drivers so i will have to trace the wires back to the sound board and see how they are crossed over.

    I will just pull the signal before the cross over and send it through a powered sub first then back to the new components.

    Now the hard part, where do i find 8ohm components in the 150.00 dollar range?

    Oy, sounds like a lot of work for what will STILL be crappy sound.

    Turn on the hifi rig. G'head, splurge. Live a little.

    Just do it.
    Find the speakers you want to try and do it.
    Come back and tell us wether or not you think it is worth it.
    I know sometimes I want better sound without turning on the whole rig just to watch South Park or whatever.

    Geez...electronics last for freakin' years. I've got a marantz receiver from 19-freakin'-73 :rolleyes: Believe me....slightly better speakers aren't going to help. There are too many other factors and limitations.

    I am, just have to find the time to do it, probably when i pick up my new speakers as i have to move a lot of stuff to hook them up.

    The TV is quite easy to work on as you can remove the entire top half to expose all of the electronics. (I had to repair the TV when the warranty company couldn't seem to find the problem)
