Keep in mind your dropping the impedance down to about 3.429 ohms with the 6 and 8 ohms parallel.I don't know if that could be causing a hum problem,but may be low for your amp.
Two pairs of spkrs in tandem
I need the help of the technically minded and capable folks on this great audiophile panel.
I am running B&W original 80 series 802's as my primary spkrs. rated at at 8 ohms..... tweaked..re-wired and all inards hard wired, soldered with cardas, great solid copper binding posts & Sand filled and tensionized side dampers to control box resonance in this (pre- matrix) design.
I have attempted to intigrate my other pair of favorite spkrs, 1996 Sound Dynamics 300ti's rated at 4 ohms, with their propietary titanium dome tweeters and run them in tandem with my 802's
In principal they have added a great deal in capturing subtle detail as well as in specificity and depth in the sound stage, most certainly in (over-all) dynamics and clarity
Basically "I love the sound" the 300 ti's seem to add that extra level of transparancy, reveal and crispness that the the B&W's didn't quite capture on their own...
THE SNAG however is a low level HUMmmmm!!!! coming from the Sound dynamic spkrs......
Mine is a complex set-up.... featuring A stereo pair of Janis SUB WOOFERS crossed over at 100 HZ and powered with their own dedicated W3 100 watt JANIS AMPS..
Also a pair of TOWNSHEND "super tweeters" connected to the B&W's
I built a (glued & screwed) MDF coupling that positions and holds the the 300 ti's upside down (forming a 6 foot high 9 driver (per side)"array" tweeter to tweeter assembley.. COOOL!!!
THE WHOLE THING IS A TERRIFIC REVALATION FOR ME!!!!! EXCEPT FOR THE ANNOYING HUMmmmmm!..
I've checked and re-checked the integrity of all connections to no avail...
If I re-move the 300ti's.. the hum is gone???...
IS it the B&W 8ohm Vs the ti's 4ohm mix??. Is that creating some kind of dichotomy causing the hum in my otherwise silent set_up ?...
I would love some help on this.... THANKS..
