What kind of cross over should i choose?
I am looking to bi-amp a pair of b&w nautilous 805 2 way spakers, and also connect a 12" sealed bass speaker(have seperate amplifier, but no xover) for low end extention.
I am after transparent and honest sound.
the system concists of:
Speakers
B&w 805 nautilus 2 wayspeakers
12" sealed bass speaker
power amps
2 x 110w 8ohm newclassd green(tweeters)
2 x 150w 8ohms diy power amp(midrange)
2 x 150w 8ohm diy power amp(for bass speaker)
Source:
Holfi xsara cd player with vol. control. only analog rca outputs.
Crossover options:
1) passive biamp for the b&w speakers and a digital lowpass filter for the bass 12inch speaker.
+ easy to get it correct, as pross rd the filter for this speaker.
+ cheap as i have a behringer dcx 2495 for lowpass and offcourse the original passive filter.
- not getting full advantage of bi-amp.
- No Hi-pass filter to to remove freqencies below 100-150hz from b&w speakers.
- need to level match tweeter to midrange level.
2) 3-way Active crossover
Using b&w original xover frequencies for tweeter/midrange xover and adding a hipass ot the midrange driver at 150hz to let the 12inch do all the work below that frequency.
+ full advantage of bi-amp.
+ Transparence of no passive filters?
- dont really understand the theori of active filters or how to design them or where to buy them.
still need to match tweeter to midrange and bass speaker level.
3) 3-way Digital xover with behringer dcx2496.
same as in the active filter above, just with options to roll of much steeper and so on.
can easylie mach levels on all drivers.
I tryed to pass the stereo signal though the behringer and to my poweramp driving the b&w speakers, grany and agressive sound, not nice.
If i decide to spend 500-800euro to upgrade it(fx jan diddens upgrades), will it gett good enoughf or will it still be the weakest link.
+ "endless" options
- alot of work getting it all to play together.
- can all those components create a transparant sound, or will it influence the sound to much?
sorry for the way to long post and thanks alot to all that read this far
what do you think?
