Okay, I'll update the saga of my
8th Nerve treatment journey. A ways back I bought 4 x Adapt corners during the big summer clearance. I will frankly admit they performed well out of proportion to their size & my expectations. The cost seemed high to a cheapskate like me, at least
before I bought them! But now I see I was a fool to wait so long.
So how do I follow up on this gain? By adding some more
8th Nerve products!

Again the cheapskate in me rules the day- I readily acknowledge the excellence of the Adapts, but as much as I'd like to complete the rest of the room with Adapts it's a bit beyond my budget right now. My thumbnail sketch indicates I'd need 7 Rectangles at a cool $1400...probably well worth it, but a bit over my budget. So I went the used route & bought a package of used Response treatments, 10 seams & 5 corners, from a real solid fellow AC'er who moved up to all-Adapts (thanks, Gongos

).
Thanks to an abundance of product, I have actually treated every trihedral corner in my room, including the
floor/corner/wall junction and all of the dihedrah corners- including the floor/wall spots. The ceiling/wall areas are treated with Adapts, with the balance being treated with Response's.
I've only had them up for six hours, so I'll reserve in depth commentary for a later time, but my initial impressions are very favorable- basically I get even more of what I had: a lack of overhang, less ringing, more clarity. The room doesn't seem to "hang onto" bass notes like it did, obliterating the "overhang" & boom that I had. How do those little things work effectively as bass treatments?

I dunno, but I will trust the combo of my ears & my Rat Shack SPL meter! Objectively the response is much smoother. Subjectively, my room sounds larger, less clostrophobic. There's "speed" and "lean-ness" I've never heard in this room before. But that lean, clean sound doesn't equate to a thin bass- quite the contrary. It seems a layer of gunk is peeled off the bass, leaving a potency I haven't had since I moved in. And I haven't even connected my parametric EQ yet!

Kudos to Nathan & Co. I'll post more after I live with the products for awhile.
