A man with a plan is better than a leaf floating in the wind! You definitely need something nearfield. Hitting the spl in not the only thing and nearfields for the win!

There is just something about the fv15hp, its very articulate (like some of the sealed subs that have been talked about around here lately), as well as very tactile IMO, especially in the midbass and very low end.

You'll have to let us know what you think once you get it setup like your talking about .
I agree that the FV15HP is a tactile monster nearfield. It will be interesting to hear if @Marc Alexander was able to test the FV15HP in his shootout and measure it against the TR of the FV18 and 1400/118.

Fingers crossed he used Vibsensor white noise as the measuring tool.

The juices are starting to flow. I'm interested in seeing both scorecards from everyone's system to see if simulated and realworld response are comparable or if there's a wide variance and will the differences be consistent across rooms.

This will probably be my last scorecard for a while.
Bass is just buttery smooth and output is fantastic.
The last picture is basically a mirror image of the front stage, but the last cab with UM-18s hasn't been finished yet.

These UM-18s are just fantastic drivers, and not to mention how sweet they look.
I suppose the next thing is getting some Vibsensor measurements.

Wow! You aren't messing around in that room!!! 10 18's in a 1300cf room on a suspended floor??? I like your style.

Definitely get some VS going...would love to see what kind of TR you're getting.

I agree, I'd also love to see what kind of TR he's getting. I don't think we've really seen anyone run VS on a suspended floor have we? At least not on a system like this. It could really help add to the database of info that's in progress in regards to TR with different types of setups and rooms.

VS on EOT intro AND White Noise 0-50hz would be cool if you can @bgtighe23

I have ran into a problem with my new sub system, The two ported at 7-8hz XXX drivers make my screen wave like high tide! This was during Oblivion while I was building speakers and all the lights on including the work light.

I been wondering how you guys were pulling this off, with huge subs behind the screen even with tightly tensioned screens. It's borderline with just my LCR's. I would love to have the 4 sub setups picture here but I just don't have the space behind my screen. Would love to have that though.

I really believe you need to have the screen as close as possible and right now I have 6 inches from the drivers due to the speakers. It could be the projector moving though so once I finish the speakers I will work on the screen and projector. I really love this all DIY setup. I really like the sound of soft domes that can play dynamics!

Me too. I've resisted the urge to buy commercial surrounds just to "be done" and I'm sticking to my all DIY loudspeaker system. Because I have a curved screen I have about six inches on the outside but my center is only an inch behind the screen.

Yeah, my speakers are within an inch, but the woofers are in the wall with the speakers against the wall.

Maybe you have reached reasonable limits for your HT. I'

My systems usually have anywhere from 2-4ft of room behind the screen to the front wall. Either way the speakers/subs would be right up close to the screen. Never once had flapping screen material. They are always tensioned.

In my case, with the sub an inch from the screen the surround or cone would come in contact with the screen. I can fit 6x18's below the screen which should work out fine.

What kind of surface should I set my phone on? Should I hold it, lay it on the LP seat? Is placement even a variable for data - taken into consideration? Because I could place it on an end table, and at the LP and I feel like that would give different results (soft, cushion vs hard cheap pressboard)

Still need 2 subs to be installed, and I just got another quote for an electrician to run a dedicated circuit. $370 for a 20 amp circuit and hard wired cat5 from router to room.

With just 8 subs, and 2nd limiter lights on 2 inuke 6000dsps (blinking - somewhat steady 2nd light), the blinds flap around, door sounds like it's about to fall off its hinges, fan blades have about 1-2" of xmax, and tons of little noises in the walls.

On the plus side, no noise complaints.

Edit: I just ran the YouTube eot intro...several times Currently don't have my tv or blu ray hooked up to the receiver. HDMI(s) ordered this morning.

Put the phone at your MLP.

Cover it with a 2lb (or so) bag of confectionery sugar or rice (to prevent the bouncing of the phone from influencing VS).

Use the white noise file in the first few post of the VS thread for the sample. It will show you your complete TR from 0-50hz.

Boundary gain. Put the SI's in the same box, same position and you'll be amazed. I tried my SI's behind the screen in a similar placement to what you had and theres a night and day difference to the tune of 12db compared to the way I have them now(see avatar), and I've gone from 12 to 6 drivers.

Can't get any of my subs any closer to the boundaries of the room than I have now.

Would love to be able to cut my system in half and still get the same performance!

I don't want to say I had nothing by way of TR from the front sub array but it was pretty much nothing. FR and PR are pretty much the same. TR has exploded. This rivals them nearfield. It's in the ballpark. While I've moved to new amp, cabs, seating, I think it's the floor doing this. I'm sure of it. This things a launch pad. No comparison between this and the riser. My thought now is the riser shouldn't of had the isolators. This is comparable to suspended floors such as my dads theater. The wife says aren't you glad I forced the issue. Yes I am. I guess we'll see, if others do this.

Wow that's awesome! So you still have the riser then, except without the isolators on it? I think the last I had heard, you were taking the riser out.

Yes. Riser taken out. Basically it's 6mil plastic as vapor barrier, then .75" OSB. I used 12x 1.5" pins per 4x8 sheet but you can float the floor too. Then your choice of topping and you've just turned your concrete slab into a suspended floor. I've been looking at the suspended as it's the open joists or span that's the source of the huge tactile advantage, when it appears to be the subfloor. I've had 2 different models with the same result.

Wow that's amazing that you feel it makes this much difference. I think I follow you for the most part. I follow on the 6 mil plastic for a barrier and the 3/4" OSB. What kind of 1.5" pins? Your using these to hold the OSD in place on the floor right, since you said you can floated as well? Do you have the plastic and OSD directly on the concrete or on the carpet (I think at one point you took out the pad under the carpet to help out the Crowsons right?)? What type of topping, a thin piece of carpet that matches the rest of your carpet maybe?

Do you think the OSB works better than plywood and 3/4" better than say, 1/2"?

Sorry, I know lots of questions Just trying to learn from one of the best. It won't be the first time I've learned something from you about or related to TR

You can buy a powder gun and nail/pins to anchor the OSB. A lot of flooring guys just float the OSB and nail tongue and groove solid flooring to that. Or you could go click lock. Or OSB, pad and carpet. I even use liquid nails to secure the OSB to the concrete. It still resonates. Same thing happened when I removed the pad and placed a piece of 3/8" OSB. It did provide a firmer base that gave the MA's TR gains but it also had the same effect as this subfloor. Certainly my wood floor topping the subfloor could help but the key, I believe, is the subfloor, not what tops it. I will cut and bind(edging) my carpet basically turning it into an area rug with felt backing like we have throughout the house, for the sound benefit. But again, thats not important. If you need a riser for sightlines, don't use isolators. Just lay it on the subfloor. I lost TR when I placed rubber isolator feet on the subs. I'm using simple stick on, one inch felt pads. The fronts sub weigh about 225lb and I can move them by slide if needed. Yet they stay put and couple really well to the subfloor. Again, the important thing is that resonates and its almost impossible to mass couple to concrete slab no matter how attached or unattached it is. It makes sense why sand is used to fill stages and risers. Unless you need a purpose built riser, don't waste your time and effort. There no question the riser works but the subfloor is much more effective and far simpler to place. I don't think the type of sheet wood makes a difference, so use the cheapest. Likewise with the thickness. There may be a small difference between the 1/2" and 1 1/8" OSB, but I doubt its much.

Before I settled on placement I had them everywhere.
