I originally had a pair of ACI Titan II subs - sealed single 12" drivers with a 250watt amp in each. They were touted in many reviews as very accurate and musical.

Well- after installing my new Submersive HP+ pair - WOW!!!!!! What an incredible upgrade. I knew I was missing some impact but had no idea what I was really missing. The Submersives are so incredibly accurate, so clear, so clean. The bass starts and stops instantly with no smearing or left over reverberations. The cabinets with the dual opposed drivers are very inert - no vibrations to be felt at all from the cabinet which is great as I am forced to use them as stands for my front mains. I don't know how to put into words just how accurate the bass is. Never heard any other subs that could do this so well.

The cabinet work is just perfect with the black oak veneer. Awesome finish work. Could not be happier.

I was nervous as I am amperage and circuit limited in my room. I am running my entire system - Denon 4520, Emotiva XPA-3, Submersives, 63" plasma, Bluray all off of one 15amp circuit. So far I have never tripped the breaker at reference level. I do plan to run a dedicated 20 amp circuit for the Submersives later.

To summarize this was money very well spent! Even my wife is happy at much higher listening levels as there is just no distortion that I was getting with my Titan IIs.
Thank you Mark for such a wonderful product.

Welcome aboard. You have discovered what all other SubMersive owners have discovered.

While not inexpensive (nor tiny?), they really do make a huge difference in the audio presentation.

Easily the most fun speakers I have ever heard !!!!

Hey guy's,

I'm picking up my F2 master today and the slave will be here Wednesday! I'm pumped to say the least. I did have a question though. I'll be putting one sub in the front right corner and the other in the back right corner. Will audessy xt32 through my Marantz 8801 be able to correctly equalize them? I'm thinking it might be difficult for audessy to get the distances correct since the subs are in opposite corners?

Audyssey's microphone (and our ears) don't care about direction, just timing.  Audyssey will deal with the SubMersives as a single unit where the distance will be dominated by the closer unit and/or the one which delivers the most upper bass to the listening position.  To be clear, this is exactly the type of setup described in the Harman White Papers describing the benefits of multiple subwoofers (the same drive signal to each identical subwoofer).  I recommend first playing the test signal with just the + unit and then plug in the slave to confirm you are not dramatically killing output from an unexpected acoustic interaction with subs front/rear of a room.  Most often it works well, on some occasions you will see what I've started documenting in thebland's theater in this thread on AVS.  After I get more graphs together I'll post the info here on our forum as well.

Wow! Now THAT is a theater room. [smile]

I just hooked up my master F2 and left the audyssey settings that were there for the co-located SVS SB 13 ultras. I will do the calibration when I get the slave home this Wednesday but even with one of these hooked up I was feeling things I never did with the ultra's and the base was deep and taught. Very impressed Mark. Everything I wanted and more and there is still one to come!

Mark,

Would you co-locate these subs or split them up in opposite corners on the same side of the room?

"I recommend first playing the test signal with just the + unit and then plug in the slave to confirm you are not dramatically killing output from an unexpected acoustic interaction with subs front/rear of a room."  

I'm not sure how to identify the above Mark. My version of audyssey has me match the subs to 75 decibels. Are you saying that I should calibrate the first one and then plug in the slave to be sure they are not being heard differently as in lower or higher decibels? Sorry, I'm new to digging this deep into things. I suppose it might be a good idea to hire someone to come out and calibrate everything...

Translation... When you plug in the slave unit it should get a little louder, not quieter. If not, try another location, or look into taking some measurements to really know what's going on.

Got both subs hooked up but not calibrated. Great sound but a little loud even at 0 gain! I went in and turned the sub volume to the lowest it will go so well see if audessy turns it down or not?? Got my first ground loop him as well. Going to try an isolater from the Shack tonight. Awesome subs with crazy clean spl. Just need to tame the beasts a little before my walls come down. [smile]

Okay, fixed the "ground loop" issue and crazy high base all at once. It was low IQ/operator error. The zero I thought the amp was on was actually cranked to the highest setting possible and the hum was the amp ready to blow my face off. . Soo, everything is great and the subs are amazing. Thanks Mark!
