Beastly!

 

Nice work DK.

 

How about you pull an all nighter and get those granite tops on there, my friend!  THAT pic will be some good looking speaker porn!

 

;)

They are all complete but I don't have pictures yet, will take some tonight. These things are so hard to move, even with two people! I still need to run a speaker cable through the floor, across my basement and back up to the other side of the living room for the second sub (I have one in each opposing corner of my living room). I hooked up one sub temporarily to my iNuke 3000DSP. I have not done any DSP adjustments and my processor out needs to be adjusted but WOW. The sub is barely moving and my living room was shaking during a movie not even known for bass.

Pictures tomorrow for sure!..

They look great! Do those feet have some kind of pad on the bottom? Wondering if they will try to "walk" around much.

they look to have some sort of pad on them, and I agree those look really nice. I assume you just glued down the granite with some sort of silicone glue?

Nice looking subs!

I bet those monsters wouldn't walk around at all @ over 200 lbs each thanks to those granite tops smile.gif

DK,

 

They came out AWESOME.  The granite tops, kick up the class factor bigtime.  

 

Thanks for posting pics!

Thanks for the all the positive feedback, these are definitely the beefiest and sturdiest enclosures I have ever come across. They don't walk at all, they came in at 240lbs each! The feet have a clear plastic/rubber pad on the bottom of each one, should protect the floor and makes it "stick" really well too.


Anyways, I actually played them yesterday and holy cow! They were barely moving and it was powerful and loud. I started messing the the DSP on the iNuke too, was pretty cool but have some questions, hopefully LTD will stop in. This is how I set it up...

-Dual Mono Mode
-Phase 0 on both channels, I tried changing them one at a time but thought 0 sounded best. The subs are in opposite corners of the room, one in front of my and one behind me so thought one might need 180 phase but guess not.
-HPF 20hz 12db Butterworth
-LPF 90hz 48db Butterworth
-Filter 1, -7db 20hz HS12 to lower for around a 13 hz HPF

I didn't mess with anything else, does everything look correct?

I also opened up the iNuke and the fan has no cowling or tunnel to direct air flow. There are some heatsinks attached though, look like Behringer redesigned it from other threads where people opened them up. The fan is 12V 80mm Bi-Sonic, I'm going to replace it with a quieter computer fan I have laying around, I'll try to match the CFM as close as I can.

One other thing, can the brightness of the orange be lowered? I see a contract section for the screen but no brightness. During a movie the lights are very distracting, especially the level LED's.


Here is a picture of the amp exactly how I opened it, nothing altered yet.

look into "light dims" they are basically stick on window tint for LEDs, you can also just paint them with black nail polish

you can place an O-ring around the knobs that helps with that orange as well

There is a thread where someone used black rubber washers around the knobs to block out the orange light.

IIRC it was Cessna who employed the o-rings around the knobs. He got them from Home Depot I believe.

They look really nice DKAudio. Looking forward to hearing more about your impressions.
Do you know what the real tuning of the box is and how it relates to the model?
Have you noticed any chuffing when played loud?
I dont understand why you have a low pass filter. Your reciever should take care of that so its not needed.

Tuning is modeled at 18hz, not sure how to discover actual. I want to get a mic and mess with REW, never done it before though.
Have not noticed any chuffing yet.
I did the LPF just for the heck of it, more or less messing around with the DSP. My UMC-1 is crossed at 80hz I believe.

OK. So did you go with the model in #55 or something similar? You can eyeball the actual tuning by playing a row of sinus test tones around the tuning frequency with the high pass turned off. (15, 16, 17, 18, 19, 20Hz) The tone that have the cone moving the -least- is the one closest to the actual tuning of the box. A mic is a great idea.

Yeah, I did two slot ports 9.5" X 1.75" x 30", all ends have a round over edge done with a router. WinISD showed a 18.1hz tuning.

Interesting on the cone excursion, I will have to try some test tones and see. I have a iMM-6 mic but have not used it yet. Got info for the cables I need to make it work with REW from another member. I have not ordered the cables yet though.

BTW. You can also estimate the tuning with the mic. Just measure the the center of the cone really close (1") with the test tones. Again, its the tone that measures the lowest that is closest to the tuning point.

Here is what I ended up doing with my iNuke 3000DSP’s fan. I already had a 80mm 12VDC fan laying around, it has the following specs…
• DF1208SM
• DC 12V, 0.20A
• Speed: 2600 RPM
• Air Flow: 27.94 CFM
• 30.10 dBA

The stock fan has these specs…
• BP802512HL-03-W
• DC 12V, 0.40A
• Speed: 4000 RPM
• Air Flow: 55.5 CFM
• 40 dBA

The noise level is very acceptable now, the iNuke has the fan spin at a low speed until it is pushed harder so at normal levels or during dialog I can’t hear the fan unless I go close to the unit.

Since this has about half the CFM as the stock fan I thought it would be a good idea to add some more heatsinks. I drilled through the metal stock heatsinks, used a thermal transfer pad and added some bigger aluminum finned heatsinks. After doing this the highest temp I have measures so far (not pushing the amp crazy hard but decently hard) was 96F with an ambient of 70F.

I played some test tones, 16hz and 17hz definitely had the least amount of excursion. Couldn't hear anything but you could feel it and the house was rattling smile.gif WinISD came in at above 18hz tuning, wonder why it is that much lower? Once they break in will it change slightly?

10hz was the lowest freq I had and it was sure moving! I wonder if the iNuke 13hz HPF is working? I set it as I described in post # 101.

Also, anyone know how long the DSP settings in the iNuke will hold without power?

I has been reported a number of times that the tuning some times end up lower than modeled. Part of it might be the down fire port. If it is too close to the floor it will effectively lengthen the port and lower the tuning. If you have some dampening in there you can remove some of it. That will move the tuning up a little. Or vice versa.

Its normal that the excursion rises below the tuning point, but If the filter is not effective preventing bottoming the woofer you might want to move the HPF up a notch.

What was the purpose of the granite top again? Using this as an end table?

Mostly just for looks, I can put items on there (including drinks) without worrying about anything getting damaged. Also makes it solid, 3cm granite does not flex smile.gif
