hi,
my first post here, and i am no electronics genius. : )
what i am wanting to do is create a pllxo for the stereomour, so i can bi-amp a kind of FAST system (sorry for all the jargon i picked up....!) basically, run little full range drivers (alpair 7p) with the stereomour down to 120Hz crossover, where i feed some helper woofers (sdx7 in the same enclosure, separate sealed) run by an adcom amp for the low range.
firstly, does anyone have any thoughts, concerns, or encouragement?
secondly, i am considering a simple first order high pass for the stereomour - less components so more transparency - and stack the effect with sealed box resonance to the same 120Hz point. so i have looked around, finding different figures - is the stereomour a 100k input impedance???
thirdly, is this basic idea right? i have a selector switch in the stereomour, and from that to the volume pot - from there - after the volume knob (an alps now) - i take two lines - one to the stereomour preamp with the pllxo cap(s) to give high pass, and a separate line to the adcom with a low pass 2nd order. does this make sense??? of course i would have a pot before the adcom to balance the sound also.... (or in the steremour if it ends up being the louder of the two amps!)
why??? sounds complicated, i know. what i am trying to get - clarity and soundstage with the stereomour and full rangers, combined with good extension into 25-30Hz with helper woofers and adcom. i am hoping this frees up a little stress for a touch more headroom and poetry with the stereomour, as well as giving me serious extension and quick punches down low. i do not want to thrash this - i just want full range, clear and transparent, at good normal listening levels.... i listen to all sorts of music, some classical, post-rock, glitch and experimental that can venture down very low in the frequency range. i want to hear it all.
happy to hear any thoughts / ideas....
cheers!
sean.
ps - i love my stereomour - i made a special copper chassis for it being a metalworker - it sounds great, and makes me smile when i listen to music. : )
