So.... Where are the specs for this sub, a DIY guy loves reading numbers!

Flip, check your PM

While I need to do another set of more ideal measurements, preliminary ground plane response of the SubMersive is +/-3dB 20-200Hz, +/-12dB extends down to 14Hz, and 10Hz is -12dB the 20Hz level.

Here's a link to an earlier response measurement with zero smoothing (2Hz resolution) and with a few reflections making for some wiggle at higher frequencies. 1m frequency response - 100dB @ 20Hz

Below 20Hz there is 6-8dB more output capability beyond this measurement, and a LOT more available higher in frequency.

Final dimensions are 17.5" x 23.25" x 24.75" tall plus 3/4" feet. The feet usually translate to ~25" of height on carpet or 25.5" on a hardwood floor.

Congratulations Mark! This product is a major ball buster from what I have heard and you deserve all the success coming your way!

So you opted NOT to use LINEAR moto tech in your drivers. i wonder why. JL AUDIO, TC SOUNDS, and HSU are using it

Hi John,

All motors are linear over some range.

When you have a pair of large 15" cones and aren't loosing significant surface area to 2" wide surrounds, linearity can be quite good as the cones don't have to move very far for very prodigious output. By optimizing the driver parameters for sufficient sensitivity at low frequencies, I am able to employ two 15" drivers, in an inert enclosure with two 3" voice coils. This results in less need for huge excursion, and less need to get around the inherent hurdles of designing such drivers. Through the development process I have not yet found reliable and viable options in the so-called linear motor designs that were suiltable or preferrable for the performance and value of the SubMersive. I am always working with different suppliers for continued improvement in the future, and I may incorportate such motor designs at some point in the future. That said, solid subwoofer performance requires a lot more than just using an alledgedly "linear motor." There is a lot more to execution of a design, and it is more about selecting parts that predominantly operate within their operating limits to achieve the desired goals.

WOW I haven't heard many other subs really causing physical damage to a room. We have all heard the "It shook my room like nothing else" but this is actual proof

Sounds like a wonderful product endorsement.

Mark S.,

Where do I sign up for your Submersive subs? Where is the web page,where is the shopping basket.I want a SubMersive. Serious buyer here.

Update.... Just watched Batman Begins... The scene when the water mains explode caused my PJ to go way out of alignment again. I think i'm going to have to get better Projector Mount or tighten the screws a lot more. All other rattling and assorted problems have been fixed (i hope).

You're running those bad boys off hardwood floors - that's probably why everything is jumping around. May want to look into one or two subdudes.

this be correct, Mark^2 the benefit though of the linear motor is the distortion lower, but u know that

do ya place any stock on ThD distortions for subs?

woulud be reallllllyyyyyyy interesting to see craig shootout of Sub1 and f113!!!!!! it be a good fight me thinks

I think you are holding a baseball bat and taking swings at your projector.

At least say pictures fell of the walls!

Hi Drew,

The subdudes would have zero effect. The opposed mounting of the drivers results in a entirely inert enclosure, even at the highest drive levels. The SubMersive enclosures are probably the most stable things in the room.

I also believe that the hardwood floor you see is on slab, at most there is a crawl space, but I don't believe so. All vibrations noted are acoustically induced.

Art,

I just finished checking out your site. The theater and the latest G2G you hosted just blew me away. You are indeed one classy guy, and the attendees have something to remember, IMHO.

A very respectful tip o' the hat. Very cool stuff.

Warren, could you show us a picture of the amp section?

Submersive does not move. not one bit. Even when we were running really high DB's they didn't move. The house has no basement and AFAIK no crawl space. it was built back in 1890 i believe and has been poorly renovated (its a rental property). All of my issues are from my neglect to tighten screws (why my projector keeps moving during heavy LFE scenes), and poor construction of the house.

I do not have an ideal room and the SubMersives easily handle it.

Also I apologize for my fanboy attitude as this has definately been the biggest transformation in my theater since i went to a front projection setup.

Anyone in the Chicago area can PM me if they want to stop by and see what these bad boys can do.

Pod Emergence -5 volume..... video with 2 coins on top of submersive

SubMersive Coins
post #48 of 9384
Are us Canadians going to be able to order the Submersive 1 up here o the North?
post #49 of 9384
WarrenB.,

May impress the masses,problem is...

This is a sub using two identical woofers that are opposed. You should see almost no movement even full tilt blasting til your eardrums give.

A single woofer sub like the JL f112/113 may shake like this from the massive strokes of the cpiston at deafening SPL.

hmmm

Exactly my question,I did send a PM to Mark Seaton today. lets wait and see.
post #51 of 9384
ok, i have headphones on, lol, but that pod emergence scene sounds really fricken deep those coins didnt move even a tiny bit!

.... and yeah, i'd also sure like to know if we Canadians are going to be able to order one of those Submersives. What is the final weight of the unit?

I see no reason why the SubMersive won't make it across the border just like any other subwoofer from a US manufacturer. I don't have any plans for a Canadian distributor if that's what you were indirectly asking, but aside from the costs involved, shipping to Canada shouldn't be a problem.

It's more impressive when the coins are ballanced on end.

I should have exact shipping weight confirmed next week as I recently changed some packing details. The subwoofer itself is about 100 lbs.

Hey Mark,

I shot ya an email and PM, but your probably a tad busy these days.
I would love to pick up one of these submersives. If you could shoot me a PM letting me know how to do so, it would be greatly appreciated. Thanks.

Just had Mark Seaton over to install my 2 SubMersives, it being late and all I will keep my initial post on this MONSTER of a sub short.

I don't mean this in any negative way, but I think it's important to note that Mark Seaton actually installed these subs himself. I have read more than one thread where MS has been hired to optimize an HT. In addition to being an expert at sub installation, his expertise has been utilized to do more than just install the subwoofer. He can, by all accounts, optimize the speakers by adjusting placement, toe-in, etc., optimize the bass management, the phase, any and all peripheral EQ systems, and tweak the overall system to sound better.

Mark, could you describe the installation you performed for WarrenBuffett? Also, will your installation services be included with some or all of these systems, or do you charge an installation fee?

Craig

Mark,
I sent you a PM and email

Looking good...a $2000 sub that might actually be worth it. Interesting to see how it does against the Fathom thingie...be nice if someone the calibre of Mullen got his hands on one or both.

If you catch the other thread, you'll see that Mr. Ed now works for SVS.

finally cat is let out of bag about *that*, i was saying that one year ago even told Mark^2 (and big kahuna Mark^1) about that, now he knows i am and was right.
post #60 of 9384
Hi, Mark. It's obviously early in the game, but is a smaller version of the SubMersive, perhaps using 12" drivers, a realistic possibility at some point?
