Default Fast corrosion (etching) method of the Corporation



This is the Dx Semprini, an amplifier sold to Semprini Acoustics (belongs to Miguel Nabuco, Mitchel of our forum) to produce an amplified speaker for subwoofer.

He will produce speakers assembled and kits.... a variable slop low pass filter gonna be used.

Watch the fast corrosion.... 130 grade for Hydrogen Peroxide (usually is 20), mixed half and half with muriatic acid...environment temperature is 27 degrées celsius:

Pcboard etching, fast corrosion of Dx Semprini prototype - YouTube

regards,

Carlos

Default Wanna more bass?

Then make these modifications.

This will change all harmonics....the THD will also change..but if you want for bass, then go ahead.

Carlos

Default Lots of bass

There are some bass songs in youtube.... bass test songs....some of them are very interesting as they mix several bass tones together...the beats and harmonics are very nice.

SUBWOOFER TEST (no joke..hard bass) - YouTube

Subwoofer Sound Bass Test Free - By Generation Soundtrack - YouTube

Bass Test - Demanding tracks for your system [Bass Test] 1 - YouTube

Carlos
