Okay! I got a couple of videos made. Poor lighting and my lack of video skills aside I think you'll get a good look at what I mean. Might wanna turn it down a little, the mic on my phone did not make the audio very pretty, lol.
You can adjust the speed with YT settings, I checked before I posted.
Okay, only 1 video per post. 1 more coming. The lighting in that one got funky for a second or 2.
Can you tell the names of the tracks?
The woofer excursion doesn't seem bad to me. The midrange, in the least, is interesting...I don't think I've ever seen a mid move like that.
That's small crossed at 80hz?
I think the dog wants in.
-curtis
I see what looks like warping with that mid. The first video captured it well, but it's also the same damn spot where the lighting got goofy.
Yup. Crossed over at 80 hz, set to small.
I'm okay punishing myself with a li'l volume sometimes but I usually put the pooches outside when I do. They don't like it very much, lol.
*Edit: The tracks are "Chocolate Chip Trip" off of TOOL's "Fear Inoculum" and "Dead Bodies Everywhere" from Korn's "Follow the Leader"

Here's an online calculator you can play with

I haven't tried that one yet. I like to play around with this one. It assumes 8 ohms tho so I deduct 3 dB sensitivity for the 4 ohm Sierra towers.

4 ohm's is minimum Impedance for the Towers. If you look at the graphs, the impedance is higher than that as you get above 20 hz. I wouldn't assume 4 ohms whilst doing your power calculations.

Using the calculator I linked, and 200 WPC for your Monolith (which is what I believe it is into 8 ohms), at 15 feet you can achieve 99 dB, 10 feet 102 dB, and 5 feet 108 dB.
I'm about 9' from my Towers, driving them with a Rogue Atlas Magnum II Tube Amp (100 wpc). Listening to vinyl, they are loud at -30 on my MRX720. I'm generally around -37 to -40 for normal listening. I don't recall what I've set the volume limit to in the MRX720 (somewhere between 0 and -10)
