but im sure it will be fine for a pc speaker setup

[diy 2.1 pc speaker]

No it was a acoustic solutions DS533!

[diy 2.1 pc speaker]

it on the side of the of the transformer it was on the pic of the transformer

these speaker where part of a 5.1 system not cheap radio

[diy 2.1 pc speaker]

that dont seem that good to me 4.3w, need to make that higher

[diy 2.1 pc speaker]

made that term up  ;D

[diy 2.1 pc speaker]

well the speakers must of been in the range of the amps that were used in the 5.1 setup. i can remember that they where pretty loud for there size.
tda2030a was for the woofer and tda2003's were for the 5 satellites speakers
and where the speaker wires clipped to the back is has (speakers out 4ohms).

the small speakers are 3"

with the transformer, if i use a Spilt Power circuit would it half the power if i use just one 15.5v
so it would be better to use the single supply

[diy 2.1 pc speaker]

i was looking into the transformer, trying to figure out how I'm going to get a + and - supply and its down to a bridge rectifier, so theres one on the board that came from amp box. its a 2w10m and on the other board theres a bunch of 4004 diodes which i can also use as a bridge rectifier

i didn't know that even the secondary windings on the transformer are still ac current and a bridge rectifier is needed to get DC + and -

please clarify

hi
the only info i found is this
Subwoofer output power 35 watt RMS
Output Power 5 x 7 watt RMS
and all that is on the speakers is 35P1 20021115A and the woofer has 65P83 20021101A

Ive emailed the Toroidal Transformer manufacturer and hopefully i will get some info.

Ive got a bunch of Lm272 op amps i used on a railsplitter project would they work?
is it a 2 way active crossover circuit needed?

so would it be better to put the speakers in parallel then

"Then simply change the crossover frequency to match your speakers"
this is getting a little, no alot over my head i thought this was going to be a simple project but i guess not

OK is there any info i could read for beginners to get a clear understanding of all this stuff
thanks

ok so there not that great

ok so i'll get 2 of the TDA7240a
should i use the TDA2030a for the woofer or is there another more efficient.

i was thinking that i could use 2 speakers in parallel or series which ever is better on each channel

ive been trying to find a active crossover circuit but ive only found ones for tweeter woofer speaker setup.
i looked up this TDA2320A datasheet as a crossover chip but im not sure if this is the right type.
thanks

so let me get this right.
Theres a slight power difference in one Tda2003 to another even though there the same.
but with a 8pin dual amp would work better cause there together in one IC.

hi
i got a old 5.1 home theatre system and i wanna recycle it into a 2.1 PC speaker set.

well i took it apart and found that it has 5x TDA2003 and 1x TDA2030A and couple 7805, 7812 regulators a toroidal transformer and loads of capacitors and resistors loads of other stuff.
also one 6" woofer and 5 small speakers.
so i was looking up the schematics on the amplifiers and found that they could easily be used for a 2.1 speaker setup

so i was thinking that i could use 4 Tda2003's, 2 bridged for left and 2 bridged for right and the Tda2030a for the woofer.
i just need help connecting it up with the power and how to have the woofer for the bass.

thanks
