The avr lpf should be used. The hpf is the important filter. It protects the driver from bottoming out due to excursion.

Well I thought if the signal is coming from the LFE rca that only the 100hz and below was processed. Therefore no further "filtering" was required besides the LFcrossover of the nu3000. Am I missing something , what do you recommend?

'The avr lpf should be used. The hpf is the important filter ' I am not familiar with this option, can you clarify as to what my AVR can do to help my situation...I really don't want bottoming out!!! thank you

"Weak subwoofers employ limiters (ie high-pass filters) to ensure that they don't self-destruct. This prevents bottoming out, longer life, etc. Some subwoofers don't necessarily need subsonic filters, like small sealed subwoofers, which act like pseudo high-pass filters."

Ok so I read-up on the subject and pretty sure my avr model can't help me. However finding and instaling the rite external hpf is of importance before sealing my SId4.
Where can I find a good filter where and how do I do the install? Anything else I should know? Martycube 17hz tune. thank you guys for your input : )

Martycube is ported and ported subs need hpf. Cube is set to 20hz. You need to buy a minidsp.

what do you think the guys using a NU 3000 Inuke do, when there using it to drive a martycube? Maybe I should have bought the NU3000 dsp model instead?

Also, on the back of my NU3000 , there is on option switch next to the lf / full range or hf ? If using my LFE from my avr couldn't I use the hf option on the NU3000?
I am feeling discouraged, not sure what to do next : (((, Matt

Ya'll will laugh but I'm using a 1977 vintage Kenwood KA-9100. It comes from the day when a hi-pass was needed to filter out turntable rumble.
My Pioneer from the same era actually filters at 15Hz, but doesn't quite have the 4 ohm current output of the Kenwood.

Again the volume from the martycube sounds very anemic but my Energy speakers are loud. The AVR volume is at -10, what gives?? Any idea's...
I starting to regret selling my SVS PC Plus...twice as loud from just a 12" and bash 350W amp...
I did put the LFE signal at +12db, helped a little
Also the driver moves maybe 1/2 inch when the amp clips!!

Take a deep breath ...... Your setup is wrong. No way svs is better. Start a thread in diy section asking for help and several people will chime in to help. There are lots of experts their. I just got home from work and have to go shopping

After further testing and comparing with youtube video of owners of the nu3000, I have answered my question. I would stop increasing gain after the first clipping light would lightly appear. The amp can be pushed more, driver is fine and the bass is better. If I still feel the martycubes are underpowered in the next few months I might move up to the nu6000DSP, will see : ), thank you for your support, Matt

Just to make sure that the Orange lights are power lights and the clipping light is red

Yep, when I saw the fist orange light, I thought it was clipping. You are correct and I will be careful of the red light. Can't be over careful these days !!lol...

You have to check there output . I had noctua but they only put out 23 cfm in low mode. I don't have a.c. in my house and in the summer my inuke was shutting off. If you have a room that gets hot then you want at least 30cfm constant. If you have a basement theatre that stays cool then anyfan will work.

I just want as close to silent as possible at 4 am and 3 feet away from my device nothing more annoying to me than to hear the whirring of fans during a silent part of a film.

Hi again, I just installed the Effizio 80 and my Inuke 3000 has the two pins...(not three like the instructions suggest ) fan works though. However it is super quiet, but wondering if it's moving enough cfm? how can I know for sure? I tried putting toilet paper in front to see what it did and it moved the paper about 3-4 inches back. The stock fan made it move twice as much...maybe a little more. Just worried that because of the two pin design vs the three suplied I am missing power? How do I know if the fan is turning at full rpm? Thank you guys, any help is appriciated, Matt

Third pin is for variable which that fan doesn't have. Its cfm is 31 which should be good. The stock fan is 65cfm which is for hot stages in live shows.

I'm just putting mine in now .

The third pin is just an rpm sensor.

One minimarty together with inuke3000dsp as well as 2500 watts to the Dayton might cost you Seven hundred to build and nothing beneath Two thousand would certainly match up it through Seventeen in order to 80hz.

You're saying the silenx is quieter than the noctua?
