  1. Hi, I currently have a build going on of a BiAmping box and need a little help. It's basically four separate power amps in one conventional-size enclosure with nice big heat-sinks. It also has: - Separate regulated power supplies for L & R - Speaker DC offset protection for both tweeter and woofers - Soft start - no speaker thump Each power amp is about 100w and is of my own design, but is based on tried and tested long-tail-pair / three-stage architecture, solid-state drivers and is perfectly stable and not prone to oscillation. Very good damping factor etc. DC offset is tuneable down to a few millivolts. I would love to buddy up with someone who owns or has built a speaker setup with an active crossover in it; two-way prefereably, but I wouldn't rule out trying a tri-amping setup at some stage. I would like to bring this to Kegworth either this or next year, so if this sounds up anyone's street or you know anyone who would like to get involved with something like this, then let me know. I'm based in North-Surrey / South-London, if that helps. Thanks all, NAP.
  2. Hi after hearing the efforts of Colin and Tony at shows (Harrogate , Kegworth) I would like to be able to at least try to get to grips with doing something along similar lines . However I have a number of severe draw backs in that my woodworking skills are pretty non exisitent , I have no workshop or other space I can use and my electrical circuit skills are pretty weak. My inital thought was just abandon any thought of this but part of me still says stop being a wimp and at least make an attempt to see what can be done . So given my lack of speaker building ability I would be looking to make changes to a current ready built speaker that I like now and remove the passive crossover and replace it with an active unit that would include some DSP control . I would also look to using exisiting ready built amplifiers rather than the kit units around (perhaps with advice and assitance I could look at using pre made kit amps class D or otherwise but not sure if this is possible or advisable.) . What I want to ask of those of you who have already tried this type of work is it possible without too much soldering / Woodworking ability ? I know that this will place limitations but at this time I just want to give it a try without investing too much in learning new skills and hopefully not spending too much money . Any thoughts ?
