Don't sell those buttkickers without talking to me first.Repooc wrote: ↑Jul 10th, 2018 10:11 amProject update and progress on the "how low/high can you go test"....
So this past weekend marks the completion of all buying all my gear to complete the HT. I bought a Behringer iNuke nu3000DSP amplifier for the 2x VBSS subwoofers (more on that below). And 4x 10" coaxial DIY speakers for my Atmos height channels... I still need to assemble/paint the cabinets and build the crossovers, so it may take some time before I have Atmos enabled in the HT.
The equipment rack is pretty well completed now, and I've included a pic below to show what powers this beast. Surprisingly, it's not a lot of gear compared to some other HTs (in terms of discrete amplification for different channels). The Anthem MRX-1120 receiver/amplifier is an absolute beast and does a VERY good job at providing the horsepower for all of the HT. Honestly, If I didn't go with the passive subwoofers, all I would need is the Anthem and just run (bigger) powered subs, like SVS or HSU Research.
Order of gear (top to bottom)
- Xiaomi Mibox 3 Android STB (not really visable... want to replace it with a Nvidia Shield)
- Laptop cooler
- Anthem MRX-1120 Receiver/Amplifier
- Panasonic UB900 4K BRD Player (with external WD hard drive plugged in via USB... trying some downloaded 4K content out)
- Logitech Harmony Hub (on left side)
- Behringer iNuke nu3000DSP Amplifier (for 2x 18" VBSS subs)
- Sony PS3 phat (I'm not a huge gamer anymore, this is a remnant from pre-kids/D.I.N.K. days)
- APC UPS (for my projector and harmony hub)
- Furman Power Conditioner (everything in rack is plugged into this)
The mess of ethernet Cat-6 cables on top is another future project of relocating my network to the basement, NAS, patch panel, switch, security camera NVR into a wall-mounted rack above the HT gear. After that's all done, I plan on installing a barn door to slide in front and stop my kids from pushing all the interesting glowing buttons.
Going back to the "how low/high can you go before your piss off your wife challenge" LOL..... Last night was another HUGE win.
At around 12:30 (kids and wife sound asleep upstairs) I hooked up the 2x 18" subs for the first time to the iNuke amp and threw on Black Panther. Mind you this is with the 2x 12" subs too... so 4x subs in total going. The iNuke is turned up to about 3/4 on both channels (still not maxed out).
With cell phone in hand (waiting for an angry text in all caps) I started out at -45. Couple minutes into the movie.... not bad. No texts. So, I went to -35; and could start to feel the 18" subs delivering some punches, but still pretty contained within the room. Gave it a few minutes before turning it up anymore. At -35 tactile response in the back row is feeling pretty good. So, I went down to -25 (my preferred listening level) and things REALLY got moving at this point. I FOR SURE thought my wife was going to kick the door down... gave it a few minutes. Nothing! So, I let the movie run, went upstairs to the kitchen directly above could feel VERY slight rumbles on the floor... nothing more than if I were watching TV in the family room. GREAT! AWESOME!! I went up to the second floor and stood outside the bedroom doors, and it was virtually silent. In fact, I could hear my kids' night time noise machine coming from the bedroom. WINNING!!
So, I gotta keep going right? Headed back downstairs and proceeded to go to -20.... at this point the HT is just BOOMING. The 18" subs are really showing their power here. And it just so happened that this was the car chase scene after they leave the club and Black Panther is jumping all over cars and blowing them up. Sitting in the front row and I'm getting amazing tactile response throughout my chair and body.... back row was just bananas!! I ran upstairs to the kitchen and can feel the floor vibrating now and dishes/glasses in the cupboards tinkling every so often. Went to the second floor, and while you could hear SOMETHING it was as if I had the TV on in the family room at this point. BUT still not enough to wake my wife up and get a text!!
But I must admit, at -20 I think it's a bit much... it's ridiculously loud. I couldn't sit through an entire movie like that. Really only good for demoing clips and and showing the room's capabilities. It's just crazy to think that the system's power is nowhere near it's maximum of being tapped out. So, all in all, the added cost of adding the sound dampening was WELL WORTH IT. Especially, if you're the type of person like me that wants to watch a movie the way it's supposed to sound. At this point, I don't even think I'll need to install the butt-kicker transducers in the chairs. I also think because of the sealed nature of the room, the room gain and ported subs combine to really fill the space.... not so sure you'd get the same sensation in a open-concept media room.
So, next steps are to build my Atmos speakers, and then I'll run the room correction software while looking into treating some of the walls with absorption panels to get rid of some reflections and "tuning" the seat riser by drilling holes into the front face. THEN, I'll bring in the ISF calibrator to work his magic on the projector. But honestly, to the non-audiophile and non-videophile (ie: my entire family) it's really impressive in its current uncalibrated state.
.... more to come. Stay tuned!!
I have been thinking about needing them in my theatre because I only got 1 subwoofer for my theatre, but I am planning on putting the sub nearfield so I might not need buttkickers but if nearfield doesn't pan out I will be wanting to do buttkickers so I would be happy to take them off your hands if it comes to that.
