[PROFESSOUR2003]

hi i have built my 2.1 sound system based on TDA7294 in bridge config. for each 8" channel and i want to start building the subwoofer unit _WITHOUT SPENDING A FORTUNE _ so, can i parallel two module of TDA7294 (each one is two tda7294 in bridge mode) for subwoofer amp and which size of woofer is the best for TDA7294.
AT LAST I WANNA THANK EVERY ONE WHO HELPED ME

you have to choose the woofer and then design your amp around it.

First find a cost effective woofer. Then build your enclosure. Then worry about the amplifier

I don`t know which size of woofer is suitable with this chip.??

Depends on what size woofer is suitable for your room. I use a 12" with mine, sounds awesome.

12" woofer with tda7294 ??

size is not the issue.

the impedance and the sensitivity is the issue.

 

[PROFESSOUR2003]

12" 8 ohm and i don`t know the sensitivity

12" 8 ohm and i don`t know the sensitivity

My woofer is 12" 8 ohm with 95dB sensitivity. So it doesn't take much for that thing to get *very* loud.
