Whoa, 4" woofer. Why not use a proper 8" to 10" woofer. After all it's all about pushing air around. Can't move alot of air with a drinking straw.

This is a little 10W amp..so adding one more opamp input I'm scared of overdriving the tda2030 making a distortion. let me say, I won't agree for a distorted output. If it no problem na, plz help me out to add a buffer using a tl074(quad for both buffer n tone ctrl). I dont know anything abt that stuff.The tone control circuit must be fed from a low impedance to work properly, add an opamp buffer to the input, and you could add a little gain there if required as well.
MusiclOk . this is my complete schematic for the amp. Let me know any errors out of the drawing.
Why u unnecessary use buffer, i send u a circuit for really u can doing easily.
and no compromise sound quality.yes buffer improve your input impedance but why ? high impedance input can collect other noise too.
A simple buffer has no gain, your tone control has no gain either (wth the controls flat), so the only gain is your power amp.
what I'm asking is without any gain how is the low frequencies are boosted to some db(?) right? Is my buffer circuit is ok for the impedance issue.
ataul,
Does ur tone control for eg, bass control affects the mids and highs in either way while moving? I want it to have control only over teh low frequency spectrum n treble ctrl has only over the high.
No.Thank you. so u mean the 334p should be applied on the tone control input also. Like this.
200K gain control is ok or do I need a 1Meg pot over ther for better control.
