ya i recommended them. i have used the tweeters that are on them but never that woofer. oo and one thing i notice is that your crossover is a little wrong. the black spool inducer should be standing up not on its side. having it the way it is now can induce cross talk between the 2 channels.

I guess its a Must, at the very bottom of the page some dude makes a comment stating that the pronounced effect is actually "cross talk". so you were right.

Time to rip em open!

edit : yeah im going to have to leave it, only way would be to pry it and destroy the cabinet... I am sadface ( an idiet frown.gif ).

How much did they cost you? There are typically solvents you can find to dissolve various glues, I am sure you can find one for whatever you used.

I have plenty of finished DIY audio projects lying a round, I might post some up later. This is what I have been working on lately;

Finally got my first M3A finished and working - Time to case it up. This amp sounds very nice.

Second one built and tested with +- 10V supply, will order a 500VA former, a rectifier and 4 10000uF caps this weekend smile.gif.

I had my first attempt at the starving student a couple of weeks ago, I went a bit overboard with the power supply tongue.gif. I designed a acrylic case, it is on it's way from the laser cutters. The amp sounds really good, I worked the design to around some pentodes I have easy access too smile.gif I still need to spray the heat-sink as it is a little scratched up from the hole saw.

Put together a another GrubDAC and Starving Student, all tested and working. I will order a suitable power supply this weekend.

I picked up most of the parts from a local electronics surplus store. The rest was from Element 14.

You may run into trouble with the 12au7's as a 19V heater is needed to bias the mosfets. I think their are schematics around using resisters to make up the difference, these will have to be of the 5 watt variety and will need cooling.

I think using a board similar to the one I used in my second attempt will give you better results.
