So a couple of things first before I continue with this post..
I have my NU1000DSP hooked up via a speakon connector in the back as required, the wires in position +2 and +1 to run in bridged, now going to the sub I simply am using two binding posts with banana plugs. Now is it not truely running in bridge mode because im not using a speakon connector at the sub? One would assume that wiring the + and - on the sub if I used a speakon connector would be the same thing as it being + and - with the binding posts?
The reason I ask, and maybe its because of how heavily I h ad to EQ the sub using the EQ in the NU1000, it seems like its very easy to get the lights to light up on the AMP. Granted ive seen the clip light hit hard a few times but have not heard any odd noise that could be clipping unless I crank it ALL the way up where its just obnoxiously loud anyways.
I got a chance to EQ my sub if your read my previous posts. I think its is good as its going to get without another 5-6 EQ points, or another sub to try and pick up some of the slack. It falls off ~4 dbs from 60-80hz, but if I try and and EQ any of those points, with the limited number of eq points the NU1000 has, Id have to give up the EQ on the low ened and loose the boost in the 20-30HZ range to make the low end flat. As it sits right now while its not completely flat my subs SPL in the 20-80HZ range where it crosses over is pretty linear While not dead flat on 85DB, it never falls off or spikes to hard and everything is pretty close to the 85DB.. i have eliminated any harsh dips or spikes, and playing test tones sounds natural and linear as it increases, I cant really here any audible drop off or spike in certain frequencies like I could before the EQ, and even with my old RW-12D..
The wife took the kiddo to the store last night so I fired up The Avengers quick, the LFE sounds great in this movie IMO. I cranked my system up to a modest -15DB (Usually listen to movies around -20 with the wife, but she wasnt there
) and at first I felt a little let down by the sub but there is probably a good reason for that, keep in mind this is the first time I really had it cranked and listened to it too. My RW-12D was loud, but there was a reason for that.. it wasn't loud across all frequencies.. it had serious spikes in certain frequenices and dips in other, so I always ran it a bit on the hot side.. and it seemed all movies picked those frequencies that were really loud, and my house would be shaking..
Now I have my Ultimax, which is EQ'ed and compared to my RW-12D, it mine as well be a completely flat curve from 18-80HZ..
When I realized this, and as I was watching the movie, listening for the bass... I realized that it had more impact.. while it dident have the loud WOW OMG WTF IS HAPPENING Factor because lets say 40HZ had a spike 10db's higher than everything else like my RW-12D had. I felt my body shake, I felt like everytime the bas **** while it did not make my ears bleed, or my house completely shake, I could feel it in my chest.. everything had an authoritative kick to it. It never overpowered the speakers, it never felt like when a guy punched another that the earth was comming to an end.. it suddenly made things feel more believable. And the detail, oh my lord the detail, compared to the RW-12D I was just amazed at how good the sub sounded. While the klipsch felt like it would just make boom boom and knock **** off my shelves, this all of the sudden quickly punches.. i never feel like the sub is making more noise than it should, like theres a drone or echo from the loud note it had just played..
This sub still gets loud, and will shake my house, but it did take a minute to get used to how smooth it sounds without the dips and spikes in certain frequncies that I had before.. but its WONDERFUL not having any more quiet to OMG WTF WHY IS THAT SO LOUD when an explosion happens
