Thanks Mark!

I'll give you a ring when the room is finished. Right now I am putzing around with HVAC options and power, which are way less fun to think about than your equipment.

Without having to look through all 347 pages on this thread, can someone point in the direction for eliminating the hum from my F2's. I drastically reduced it by plugging into a Richard Gray 1200, but its big and in the way of updated setup.

My setup is a pair of F2's, one in each corner about 10-15 ft away from AVR, each

Thanks

Well, i discovered today my main cable for Direct Tv runs straight from the dish to the receiver with no ground. Direct Tv is sending someone Tuesday to ground the system. Could this be the cause of the hum?

No, that ground is for other things like lightning. Can you try different outlets (AC power)?

He said the cable from his dish (LNB) to his receiver. Grounding this connection helps with static build up, etc.

http://www.sadoun.com/Sat/Installation/Grounding.htm

The reason I said AC outlet is that signals (electricity) take the path of least resistance. Sometimes that path is through your equipment vs. the indented ground causing hum. AC outlets in homes tend to be "daisy chained " to a circuit and sometimes using a different outlet shortens the ground and fixes hums.

http://www.techhive.com/article/3063...o-systems.html

Can you please provide details on how subwoofer hum is introduced via a non-grounded satellite dish connection?

I have had HUM from cable boxes due to the coax from the outside box to the STB not being grounded. The noise is in the signal path of that device.

Not sure about from the LNB on a dish.

I use to have a LNA on my 10' BUD back in 1982...

I have replaced all the outlets with Shuyanta outlets and Shuyanta plug in suppressors. Had the electrician here and isolated outlets used for home theater. Says there is nothing else he can do.

I will be replacing my Marantz with rca sub outs with Anthem AVM60 with XLR sub outs. Hope this will help.

Changed outlets, grounding Direct Tv, changing AVR and what works best is the Richard Gray 1200. Eliminates about 50% of the hum. Trying to get rid of the other 40%-50%

Thinking about running speaker wire or small guage wire from ground on AVR to somewhere on subs, really want to avoid that

Ground it yourself. Drill a hole through the wall and run 10, or 12ga OFC wire to a grounding rod outside pushed into the ground. Seal the wire hole up with silicone ( that matches the decore, of course). Really, people make such a big deal out of this stuff, and really it isn't.

In case you have not done some basic sleuthing, here's some ideas to help isolate the cause:

1) Try the ground lift plug if you have not already done so. Is the hum gone?
If so, you're done.

If not, 2) disconnect the sub's input cable from the preamp output. Is the hum gone? If not, go to step 4).
If so, 3) touch only the ground/shield side of the cable to the jack's ground. Does the hum return? If so, there's a ground or power circuit war to investigate. Let's talk about this later if needed.

4) Disconnect the cable where it enters the sub's amp. Is the hum gone? If not, go to step 6).
If so, it appears the hum is induced from something nearby.
5) Move the audio cable to a different location, or use a different cable taking a different path (even if just temporary) to see if it affects the result. Or maybe there's some other equipment nearby that can be turned off temporarily.

6) Apply a short across the input jack of the sub's amp. Can also be done for XLR inputs but there you have to jump both signal pins 2 & 3 to ground. Is the hum gone?

If not, the unit appears either defective or entirely unhappy in its environment.
If so, it proves the sub's internals are not the source of the hum.

Happy humting

It is best to try to isolate the item introducing the hum. Perhaps you could just hook up source dvd to AVR to monitor and speakers including subs. If no hum add back one device at a time to see if it introduces hum, etc.

Has anyone heard from Mark? I hope he's not trapped under a large appliance.

I've sent him e-mails and no response. How is he going to fill orders with a looming deadline if he's out of pocket?

You may want to call him. Lots of folks getting ready for CEDIA EXPO next week and Mark has stated he would be attending.

So, Mark has a sale going for pre-owned amps usable internationally($700 off). I call him from India and he spends 30 mins talking to me, patiently answering all my questions.

After a bit of back and forth, I decide on the HPi+ in black maple. I call him to make the payment, and ask him about the warranty on the pre-owned amp. His response: I see we have a new amp on the shelf from last year and I am going to send you that one instead of a pre-owned. For the sale price, no less.

There was no real business reason for Mark to do this. I would've been none the wiser if he hadn't told me and he could've sold that amp for the regular price.

You know what though? I'll remember this gesture forever. It's the little things like these that really, really count. Not to mention fantastic product quality. Thank you Mark!

I await the shipping notice later today and look forward to being absolutely blown away when I receive my Submersive.

We all know changing the location of a subwoofer in a room has an effect on its frequency response within the room. However, what if you keep the subwoofer in the same location but change its height? Will that also change the frequency response? Lastly, what if you stack multiple subwoofers on top of each other? Will each additional subwoofer stacked on top change the frequency response?

Of course moving a speaker up higher will change the response in the room (there are three axial modes that affect response - width, length and height). I have done the experiment but the changes were more subtle (but still significant) than other physical changes I have made. To reduce the chance of a visit to your local chiropractor, you can get a feel for the kind of change you will get by using REW (or other measurement tools) and put the mic an the normal listening position and them lift it a foot or two or three and you will see the change.

Stacking subs forms a bass array which has different characteristics, lobing etc. It looks like the Seatons allow separate delays for the slaves which would allow Beamforming. The subs seem to be designed to accommodate stacking. It would be interesting to hear Mark's comments on this

The separate delays are between the powered master units. The passive slaves receive the same signal as the master, so the separate delays are really set between the master units.
