Another just finished brick.
A Hifimediy T2 (stock), a SMPS300R from Connexelectronic, a Pesante enclosure from HIFI2000 and a lot of patience. Sounds very good, an very rich and detailled soundstage.

And yes, 220 V kills.

So, be careful and responsible (and forgive-me for going off-topic).

This is the way I implemented 125asx2 power module into the housing. It is made out of perspex, on the sides it is opened so that the module doesn't get baked.

Very nice work, mravlca! Beautiful!

Also: you are someone of great taste. The Prodigy are amazing. I wish they'd come to North America some time. We didn't even get to see a screening of World on Fire at our movie theaters. Amazing band, very underrated.

Great design. I think you achieved the goal of every DIYer: not to hide in a black opaque box all the work invested in the construction (like me).

mravlca · 19th September 2011, 08:59 PM

Thank you all for great compliments!

@J.R. Freeman: The Prodigy are amazing group. BTW I also didn't see the movie World on Fire, but I am thinking to buy a DVD.

Best Regards,
Ales

My board

tangmonster · 26th October 2011, 07:29 AM

my woofer amplifer:

2 x L15D (irs2092)
balanced input ,with one speaker terminal inverted ( to help with buss pumping issues)
40 0 40 V AC 800VA toroidal
3 x 10000uf 80V capacitors per rail.
30ohm slow start for around 150ms with seperate transformer.

Own designed chassis (1.6mild steel black powder coated ,with anodized faceplate)

tested for just over 300W rms per channel into 4 ohm resistive.

My woofer EQ (technically not for this thread)

Took the Marchand bassis circuit diagram and added a 2 channel parametric filter and designed my own board. For use with my twin 12" sealed woofer I built.

Things on right are mediaplayer, DAC and couple of tomatoes.

Like the enclosures .... where to get these

Thanks Baldin
