Seaton Sound SubMersive1 - Page 222

If you plan to use both (Anti-mode and Audyssey or MCACC) you will need to run Anti-Mode first and then run Audyssey or MCACC.

I love a small house curve but the one posted in the referenced Home Theater article has a 16db drop from 20hz to 20khz. I've tried 10db and thought it sounded awful, much less 16db!!

My curve is close to 20db and think it sounds killer!

Can you post a graph of that? I'm curious how 20 compares to say 50, 80, etc. thanks!

I do setup on the subs with Anti Mode, then run full auto MCACC. I have had Pioneer originally then I went with Integra & Audyssey Pro. Had the Pro Kit and laptop and did my own calibrating with it all. Had over 2500 invested in this just for movies. I didn't like the flat SQ that Audyssey gives. Also, it had too much control over the sub channel with way too flat SQ for me. I then sold it all off and went back to Pioneer. Pioneer with MCACC does not control the sub(s). The lowest that MCACC calibrates is 63hz and that is not low freq territory. Anti Mode fills in nicely in this area and the flatter that you can get your subs too, the better SQ with the speaker channels.

I'll try my omni-mic again and try to save some graphs but busy redoing my stairs......I'm almost done.

It's not a true 'curve' but by boosting my sub it gives it a pretty good upswing in the bottom end....like I said, around 20db (I also ran Audyssey with my SvS Ultra then did a clean swap to the SubM).

I think I'm gonna switch over to Pioneer and get the dual core anti mode.

Thanks for the time to write how you setup bsoko2. That 'll save m time searching when I make the switch.

So I recently got a OmnicMic v2 and have a pair of HP's in a roughly 25x25x8 area which is my LR. Kitchen & Dining. The HP's are in the front corners and the couch is in the middle of the room width wise but 1/3 of the depth.

I just started playing around with the omni mic but having the mic next to me on the upper cushion playing music with the subs turned up way hot and the receiver at +15 I saw bass peaks of 136dB around 45hz and the subs are 14' from the main listening position.

and you had your hearing aid turned off?

That was peak not max right? I'm guessing max was around 126 if peak was 136? That's really impressive, I'm maxed out at around 120 with my 2 submersives.

Hearing aids probably committed suicide.

When I was watching War House, the Trench scene with the German artillary coming in, I was hitting 113 db and my ears started to hurt. I tuned down the bass to a more normal listening level. We all know that our Submersives can do it, we just don't listen that loud for any movie. Normal bass peak for me is 108 db and the reciever volume is -10. The audio is clear with the amount of wpc and the speakers that I have. SQ is amazing. Some movies (like Black Hawk Down) I can watch at -4 and the level is comfortable for me. The SQ in BlackHawk Down is so forgiving but clear. I would put the new realease of Star Wars BD the best for surround sound. I have really never pushed my subs to see what they can do, just afraid that I would blow out the windows in the house.

I was wearing over the ear muffs.

I normally watch at -5 to -10 on the receiver with the subs two clicks up from off. This run the receiver was +10 and the sub was hot another +7 and the HP amps were 12 clicks up from off.

@Carp.. max was actually 131dB with the peak at 136dB. It was insane but very short lived(seconds).

I still need to learn about Audessy and Omnimic more and will post screenshots soon enough. I had to just try a quick max run because I knew it was LOUD after trying it without the omnimic and my old car audio days.

For information on Audyssey, see the links in my signature below.

Froggy, how big is your room? You are kicking my arse.

TY Giomani for the links.


26.5' wide x 25' deep x 8' high.

It opens up to a 4.5' wide x 9' deep front entry and a 39" x 16' deep hallway both of which are 8' tall. Both of those openings are in the left rear corner of the room relative to the main listening position.

All the bedroom and bathroom doors get closed for movie time to minimize the acoustic leakage. Although I left my master bedroom door open(opens to the LR) for the max SPL bit since I was in a hurry and that's an extra 13' x 15' x 8' area bass was leaking into.

There is one sliding glass window and 3- 5' x 6' windows in my room that are double paned.

I need to still get full curtain length light control drapes for the windows for light control and some minor acoustic reflection absorption I hope.

I don't yet know the acoustic cause and effect but I currently have the subs perpendicular in the corners instead of parallel.

Travis

Ummmmm... 45 Hz has a wavelength of 25.1 ft. You have two room dimensions very close to this. I suspect you were measuring a big peak from two, coincident room modes. Did you save this measurement? It would be interesting to see it if you can post it.

Craig

I did not but I will. I should try the test tone disc that comes with the omnimic program to measure SPL at several frequencies.

I was reading some reviews from Keith Yates done in 2004. In talking about the F**kin Irene scene from BHD he said:

"The fire-up-the-choppers scene a little more than 35 minutes into Black Hawk Down (Figs.C1 and C2), seen as vertical stripes in the waterfall plot, calls for sustained, high-level engine and blade throbs at around 7, 18, 31, 43, and 55Hz. No sub I've ever measured has mustered enough grunt at 7Hz to have a hope of hitting the 103dB level required at that frequency to be barely audible."

Are dual Submersives in room able to hit 103dB @ 7Hz? I know it's going to be hard to do for ported subs.

I'd love to know what Mark has to say, but my guess is yes if the room sealed and not too large.

Ok here is my rough draft. I have run Audessy once but it is not illuminating so I am not sure if its filters are impacting anything at this point. The FR graph is at 1/48th octave smoothing fyi.

The SPL graph I should have taken a a print screen in action instead of an after the fact one showing the save numbers but no sound in action. I didn't realize the omnimic software screen shot is of only the graph and not the whole program screen.

Anyhoo here you guys go:

^^ Try changing the vertical resolution to 5 dB instead of 20 dB. That will help a lot.

Froggy: The resolution of your graph is not granular enough. Change the db scale to no more than 5db and we can tell more of what is going on

OK guys ...new to this forum so be patient with my ireverance BUT what is the big deal with the Seaton Subs? How different are they from other sealed subs out there? What makes them so special to have such a following?

Thanks for your replies...just a curious newbee here

From your different postings on the net to do with subwoofers, you are not a NEWBEE. So why the question?

Answer in less words than this -

New amp, 2 programs, build quality, accessibility. support

I would add sound quality - bass extension, articulate, awesome for music AND movies.

most sealed subs have HP filtering to prevent them from going much lower than 20hz or so (some a bit lower some higher)

the submersive follows a true sealed alignment roll-off and can reach down into the single digits and it has the woofers and power to back it up. others do not which is why the filters and limiters

having response that reaches that low not only helps with HT performance but arguably brings out more "musical" qualities also. since the sub is "tuned" via DSP to have below 20hz anechoic response, the sub is free shine even more on those "easier" frequencies found in music

also the dual opposed design eliminates all box resonance and any possible "coloration" to the sound

and finally and more simply it has 2 very robust drivers and a massive amp. i don't know of another sealed sub in it's price range or any price range for that matter than can match ALL of it's qualities unless you go DIY

It's the secret sauce.

Has anyone taken pics of the Submersive driver(s) out of the cabinet?

I can't believe no one has mentioned appearance. It comes in several beautiful veneers.

And last but not least Mark Seaton. A great guy willing to put his considerable knowledge to use for his customers even for issues unrelated to his products.
