Anyway, crossing the subs over higher really brought the mid-bass up a notch.
The sub is superior to the studio 100 in producing bass in the 15-150hz area to my ears.
So, yesterday, RH sub fires up with a load thud, very loud. LH one fires up as usual with a barely audible clack. Walk away and the RH sub does the thud loud again,. Hmm. Gotta make breky for the little one so I continue walking away.
2 mins later another loud thud. Run upstairs, unplug it. Plug it back in. It comes on after about 30 seconds(music is playing already) with the regular clack.
Phone dealer. They will call back when somebody is available.
I also discover that the dealer ran PBK with the x-over at 80hz, and phase at 90. Sub worked the rest of the day admirably.
Basically all dials at 12. I was there when they did it, and heard the one guy tell the guy at the subs to set x-over at max, and phase at 0. Guy on the phone at the dealer says it doesn't matter when the USB is in. Ok, don't know, but the graph went well above 80hz, so maybe.
Anyway, go to fire it up today, the loud thud goes on and off again, then the sub dies. No nothing.
I am unduly impatient with this kind of thing as I am an instructor during the day,and fabricator the rest of the time. Both ends of my day rely 100% on being able to display exceptional skill, and customer service at the highest level.
Needless to say I'm not happy, and the dealer is in no rush to even call me back. Gonna be calling again, as it is completely dead. Tried new cables, everything I can think of.
Seems I was unlucky enough to find another lemon sub from PD.
At least I bought 2. Not sure if I should call Paradigm at all, judging from the sub2 thread.
