Seaton Sound SubMersive1 - Page 249

Yes I have it done per your specifications, for better or worse.

That's funny. There is a scene in one of the Bruce Willis Die Hard movies where he is driving this semi on some freeway ramps and a jet fighter is trying to eliminate him.

I have a friend who has the best two channel system I have ever heard and a really, really nice HT and I played this scene for him, and at the conclusion of that scene (played at reference), he looked at me and he was exhausted. There is so much going on and so many sounds (and some fun bass), it really is "involving".

There is not a commercial movie theater I have ever been in that can replicate that.

Happy Thanksgiving to all my American friends here on AVS!

I have a strange issue with my Submersive HP:

Whenever the subwoofer amp is on but there isn't an input signal (e.g., my AVR is off), the subwoofer starts picking up and amplifying radio signals. I can basically hear the radio through my subwoofer at low levels. Doesn't happen when my AVR is on... The sub is perfectly silent then.

Never had this happen before with the other subs I have owned.

Any of you experience this or know how to remedy this odd phenomenon?

Just for fun...

Happy Thanksgiving to all bassheads here! I know we were/are all itching to show off our submersives' capabilities to family and friends who have no idea what a "subwoofer" is.

I've discovered a problem with my F2's. I noticed that the whole house shakes every time when I play anything that has low frequencies - even at moderate levels. Can anyone help me?

HAPPY THANKSGIVING to all of my american friends.

Lol.....But alas, that is a wonderful "problem" that many "un-submersed" enthusiasts WISH they had

LOL, I had the same issue too. Oddly enough, it never happened when they were hooked up to the Onkyo 5008. It only began happening when I had to send the 5008 in for servicing and hooked them up to the Oppo BDP-93's multichannel analog outputs (basically connecting all the speakers directly to the Oppo 93 since they all have external amplification).

When the Oppo was ON, even if it wasn't playing anything, the whole system was silent. It was only when I turned the Oppo OFF that the SubM HP's would pick up radio broadcasts... for about 20-30 seconds, then it would fade away back to silence. The first couple of times it happened was late at night and I thought some dumbass was blasting their stereo so loud late at night, that I could hear it inside with all the doors and windows closed. The fact that it only happens (in my case anyway) for the first 20-30 seconds after the Oppo is turned OFF and then fades away added to the assumption that it was external noise, until I pinpointed that the sound was coming from the subs.

Now that the 5008 is back, it doesn't happen anymore. I don't know what exactly it is about the 5008 and Oppo's analog/RCA pre-outs that are different that cause this to only happen with one but not the other. Or why it only happens for 20-30 seconds. Almost seems like while some capacitors or something in the Oppo retain a residual charge, it becomes a radio antenna, and once the residual charge fades in 20-30 seconds, so does its tendency to become a radio receiver.

Just won the winning bid for a Submersive HP on epay for $1487.74. This will now give me Quads in my HT room!

Wow, great price - nice job. I'm a bit jealous...

NOW I am done!!!!

^^^

are you gonna make me go find the previous posts from you that said you were "done"?

quads... damn... my manhood just shrank...

Who in their right mind let an HP go for under 1500?? I think Christmas came early for you!

 

Way, way cool!!  Fantastic price too! 

I've heard THAT before. In that size room, you will have a huge opportunity to really hurt yourself. I have 4 in a room a good bit larger than yours and it can get really, really scary!

Congrats (It must have been a very desperate person to sell at that price). I wonder what he "upgraded" to?

Baby on the way and moving to a new home with less room.

Sorry for this naive question but with three Submersives I assume you can play reference with no distortion and your frequency response is fine, what is the advantage of adding another sub?

I have four Maestros and one Submersive in a 20x40 room and I was wondering if adding a second Submersive would provide any benefit.

   Sometimes people just have to downsize. I have the two SubM's that belonged to the person that started this thread. (He
had to go to China, I believe)

In my case, two was enough but the placement was asymmetrical to get flat FR and my OCD nature would not allow it, so I got two more. Assuming you have adequate headroom (don't know much about your Maestros) and flat FR I can't think of any reason to get another SubM UNLESS your other subs don't dig as low as the SubM's.

Hey guys,

Anyone else not able to communicate with Seaton sound? Waited all last week for them to get back to me regarding my submersive order, but no update. Is it because of thanksgiving? Not familiar with how the tradition works as it isn't celebrated in my country! Or maybe I've just annoyed them too much with my countless questions and emails.

Many businesses here close for the week of Thanksgiving and Christmas....then there is New Year, Valentines Day, Groundhog Day.....

 

 

 

I asked an electrical engineer friend of mine (who also happens to be a Radio Ham) and this was his reply:

 

 

"TBH, it's difficult to say without seeing the exact hookup & the schematics of the kit involved, but yes, it's not inconceivable.

 

The outputs of the Oppo are dynamic, i.e. from an active component, either a discrete transistor or an IC.

 

When there is NO power they probably represent a finite, lowish impedance to ground, which will probably look like a short-circuit to radio interference picked up on the cabling.

 

When the power is ON, the output impedance is invariably low, because that's how we engineers like most outputs, & again, signal pickup will be attentuated.

 

However, when the equipment has its power switched off, depending on the design, it may well take 10 or 20 or more seconds to discharge the power supply from its normal level to zilch.

 

The electronics are designed to operate correctly at the normal power (voltage) level; what happens when that voltage is seriously lower than that can be anyone's guess, but the engineer would prefer to say it's "indeterminate".  :)

 

It's quite possible that the output stages are oscillating briefly as they power down, or maybe have just drifted into a high-impedance state.  Either way, they are allowing radio signal pickup to exist on the cabling to the sub which, as it has its own amp, is amplifying it to an audible level.

 

Nothing to worry about, particularly."

That's what I would have said.

I know ideally you should have a dedicated 20a breaker, but would my current 15a outlet be able to handle the hp amp or would i be tripping the breaker all of the time. i don't listen at reference(usually -10/-15). my add'l equipment is fairly efficient meaning averaging 150 total watts on a normal bases.
