but im sure it will be fine for a pc speaker setup
-
No it was a acoustic solutions DS533!
-
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
-
that dont seem that good to me 4.3w, need to make that higher
-
made that term up ;D

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

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
