how high?

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

   i run mine up to 80hz which seems to be in keeping with the status quo, i have no need to go higher but i do have a freind about to score himself a pair of fk1 res4s which go down to 114hz. the plan quotes 119hz as the upper f3 point- does anyone actually run this high? are there any major issues with a res4 + x1 setup apart from the obvious mismatch of (albeit brilliantly designed) diy and high end pro cab?

	the only thing more dangerous than a person who doesn't give a f*k is a person who gives a sht.

	problem that usualy occurs with bandpass designs is at the upper crossover the group delay gets rather peaky and tends to sound a bit ropey without the peramiters to make a plot of the x1 to hand i cant say for certain this will be the case but i can say its a good rule of thumb to cross a bandpass as low as possabe in its passband to try and get into a smooth area of grroup delay to avoid a boomy sounding crossover. with an F3 of 119Hz youll need to go to around 130 -140 odd Hz to give the res4 enough low end respons to cross over nicley, my advice would be hd15.

	i thought that may be the case- they will eventually end up with a fitting box underneath it's just that i happen to have a pair of x1s.

	allways worth a listening test if the components are lying arround, and available just dont hold out for magnificent kick and make sure the res4's are adiquatley high passed.
