Wiring tops

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   HeyLooking to get some tops for my system but with all the research I've done into the bass section of rigs, i am still very New to the top side of things and have a few questions.
First off , if buying used commercial tops as opposed to building and loading my own , does it still require biamping ?
Secondly  if I were to build a top like an mt121 how would I wire it from the crossover so that both drivers in it are powered? Would I use different outputs on the crossover so that there is one for high frequency and then one specifically for ultra high frequencies for the comps ? If anyone is able to clear up my confusion it would be greatly appreciated :)

	DIY or pro build second hand can each be biamp or passive. an MT121 would normall require biamping aka: - a HF xover channel (say 2k-20,000k hz) - a midrange xover channel (say 180hz - 2k hx) - a HF amp channel (around 200w....or whatever) - a mid amp channel (around 600w...or whatever) Each amp channel can be connected to each driver by an individual speakon or by a 4 core speakon which is essentially 2 speakons in 1 cable. We use a 4 core speakon with a "Y" end with 2 spekaons for each amp. Each forms the 1/+1 and the +2/-2 poles of a 4 core speakon.
