SteveNN Dual RL-p15 Wanna-be

[JonW]

Yep, that’s one fun sub. :T Kind of looks like a ‘fridge to me. I found the output to be *very* impressive.

No idea how it compares to my/Steve’s sonosub because we demo’d Ryan’s with movie scenes and I’ve only really used mine with music so far. But there is one interesting difference with Ryan’s: His drivers are side firing, so you can watch them move while playing. Kind of distracting from the movie but kind of cool, too. You can’t see that driver easily on my or Steve’s sub. Anyways, I had never seen the Blackhawk down “f*#%ing Irene” scene before. Those drivers were just flapping in and out. I didn’t measure it or anything, but it had to be getting close to an inch out, near Xmax, I’d think. It was also odd to see the drivers moving so much but not being able to hear anything. Didn’t really feel too much either.

Ryan, you have to add in the EQ and then see what you think of it versus the sealeds.

Yes, definitely a big success. :T

Is that the one with the helicopter blades? If so, Bruce T measured the fundamental at 6 Hz. That low, below port tuning, a ported driver is out of phase with the port so you won't hear or feel much of anything in spite of the huge cone movement.

I
I'll get the wife to leave and try that scene with the sub off and a couple of different crossovers and see what is what.

I just remember being so blown away by how real and impactful that scene was at the Contra demo I attended. Maybe it was more the B&W speakers and full package. We'll see...

From the waterfall thread at AVS, the Open Range head shot:





I'm not exactly sure what part is the actual shot & where body sound is, but it looks like wherever it is, there's some 65+ hz content to it, so maybe some of it is out of the sub's range.

Got a chance to check out Ryan's sub yesterday along with Jon. Man, that 1.25" port flare is pretty nice! The sub just laughed at every demo we threw at it. With WotW in DTS (hot track) at -12 in Ryan's somewhat small room, which was pretty darn loud, it was clear the Ascend 340s were getting kinda harsh at those levels....meanwhile the sub was just laughing, having a good old time. If someone really wanted to get the most out of a LLT like this, you need some pretty beefy speakers all around. Also, and not to get off on a tangent, we played the lightening strike scene and Blackhawk's down f'ing Irene scene at very loud levels and there were no issues with distress or bottoming at all.

What stood out most to me was the concrete floor in Ryan's room. I'm used to powerful low bass scenes causing my floor to shake, my walls to tremble, and a sense of instictual fear and unsafety being created. Some will debate that these room effects are unwanted distortions, and yeah, technically they are, but I feel they add a lot to the experience. Take those away and it's a very different experience. Jon also noted, as we were seeing the cones move with f'ing Irene, that nothing really happened.

No problems with sound quality on music, though I'd be interested in hearing it again EQ'd flat. There may be a difference in sound quality between the Avalanche 18 and the RLp-15, but I can't put my finger on it without a more direct comparison, and it may very well just be the in room response. It will probably sound like I am Monday morning QBing because his at the seat FR is posted in this thread, but it did seem as though some midbass was overpowering bass passages. All in all though, definitely a success :T

exactly what I was looking for :T

although, it would have been interested to see more feedback with music, and with the sub EQ'd....

sounds like Ryan got himself a winner! :T

Can someone please give me a quick explanation on what I am seeing here.

What do the colors signify?

Thanks

The colors are dependent on how one has setup their PC.

In the one above the dark red colors are the loudest. So there's an interesting sound around 7Hz and another at 25Hz.

Here ya go Mike, this is the thread that came from:

http://www.avsforum.com/avs-vb/showthread.php?t=605496&highlight=waterfall+frequency+pink

The very first post has a quick explanation, then there's plenty other graphs to look at too.

I always try and add in MY color scale when I post a bass waterfall.

Steve, Jon,
Thanks for the feedback. We'll definitely have to get together again sometime and do more listening.

And so everyone knows, you'll see looking at the in-room graph I posted earlier, that there appears to be a room gain hump around 50 - 65hz. It shifts around a little depending on where you are. I haven't EQed this out yet, because I don't feel that I have spent enough time listening to it un-EQed. You know when you go switching things quickly based on graphs, you can get going to quickly and not really hear the differances - if any. And it is real easy to make it worse. So, I want to take things slowly.

And Jon, a Fridge??? :P

And Jon, a Fridge??? :P

Yup. It looks like a ‘fridge. A brown ‘fridge from the 1970’s. :P

Oh, by the way, I put my drink on top. It got sucked into the port. Shouldn’t be a problem, though, because all the cone movement will keep a nice breeze going in there… And my drink will stay nice and cool.

Yup. A ‘fridge. :

Thanks for the info and the link everyone,
