OK...Added 2 HSU ULS-15Mk2 subwoofers To My System

After unboxing , I put one next to each speaker on the outside edge just to get started.
Followed the directions to get a base point on adjustments and then I listened to a couple of very familiar  Lp`s

I found that these subs are VERY distracting.....In a good way 
Naturally (at least to me) when someone adds a couple of 15" subs to a setup they have a tendency to focus their attention on bass and all that.
But I was hearing  many new sounds and DETAIL too that I had never picked up on before.
These sounds are not 'bass territory'... how does a Triangle image so much further out to the side now ?  

The next morning I dragged my Adcom 575 CD player from the garage system and powered up the subs only and put the RHCP`s Californication on repeat for about 12 hours or so.

Then did the crawl and moved the subs around and listened on and off over a week or so and then did another crawl and made changes to the settings on the subs too.
Getting better for sure. I think HSU recommends 30 hours for break in.

So far I absolutely love these HSU subs for what they are doing for my music !

I`m also finding that the numeric volume display on the Tortuga Preamp is down a bunch from my usual levels.

So, I now have 3 15" sealed subs in the room, the HSU`s and my Revel Ultima 15

Lindsey Stirling's` Shatter Me' has never sounded so good !

I've long considered most systems I've heard to sound too lightweight, lacking the heft and visceral qualities heard in live music. That lack of weight is accompanied by a lack of lower-midrange/midrange tonal density: instruments are robbed of their full, complex timbral character, sounding anemic, eviscerated, "washed out". It's analogous to lack of full color saturation in photography.

I find the fact that the lower few octaves contain SO much information in such a limited range of frequencies: the bottom four octaves cover only frequencies 20Hz to 320Hz, a span of 300Hz; the top four octaves 1280Hz to 20,800, a span of 19,520! Interesting, ay?
