Are you looking for a specific ported box design? I can come up with something in a few minutes.

You can always turn it down, but you can only turn it up so much (before you run out of power, excursion or structural integrity).

I want to verify this is right. This is a mini marty with the port out the back. Is the port length correct? The same port cutlist length was used. 43"

Yes, as long as it's open cell foam (you can blow through it).

Hi team - i am running two micro martys off a 3000dsp. Would swapping it out for a 6000dsp with double the power give me an upgrade?

What drivers? What impedance? What's the power required to get the drivers to xMax in those boxes?

Remove the limiter, you don't need it, and it's just going to make you hit the limit light before you're at full capability.

Then set your sub trim nice and low (around -10dB is good) and then increase the amp knobs until your subs are back at the level you want them to be. Then keep doing what you're doing with the RP1 race scene and see what happens with your limit lights. The low sub trim will protect you against AVR clipping and amp input clipping.

It's perfectly fine to hit the limit lights on the loudest hits. Even with the limiter "disabled" it still kicks in right at the point where the amp starts to clip. They designed it to always be a safeguard against hard clipping.
I searched your other post and found where you said to remove the limiter for the ST HST. But it has a rms rating of 2k where the Dayton he is using has a rms rating of 1k. So you still recommend removing the limiter even with the Ultimax 18s?

I did a few measurements of my dual Full Marty setup. My mic started clipping though so the attached file is where I maxxed out mic wise.... 16hz HPF in place. The blue line is the clipping measurement.

makes me feel a little better about increasing the nx6000d wattage limiter. If you aren’t running one and the subs are performing well, no reason to have such a low limited set on mine.

I'm adding two Marty Cubes with a UM18-22 drivers and am looking for some help to make sure I don't screw up the wiring. A couple questions:

- Do I need two RCA to XLR cables from the AVR to the iNuke? My AVR (Denon4300) has two outputs just wondering if I can run one and them use bi-amp mode on the iNuke.

- I get confused with all the series vs parallel stuff so wondering if someone can take a look at the picture below and let me know if I've laid things out correctly. I'm a visual person so this helped me visualize things.

Thanks in advance!

You can do either. The Audyssey XT32 on your AVR-X4300 will set distance/delay separately for each sub, or you can handle that in the nu6k.

Your diagram is correct for a 4 ohm load to each channel.

Sub builds: Yet another Infinity 1260 build | Twins! | Modified V.B.S.S. build | UM12-22 builds | AV stand and sealed UM18s

Speaker builds: DIYSG HTM-10 build | DIYSG Volt-6 build | DIYSG Fusion-8 builds

Awesome. Thanks for the confirmation. You can never be too sure especially for a newb like myself.

Yeah, but they're long gone. They all look pretty much the same though, with ported (blue) showing more SPL until tuning, and sealed (red) showing more very low, but at such low SPL, it doesn't matter anyway. Something like this:

Thank you, sir!

Here's another question a colleague has about these: Any idea what the 2.83 V sensitivity of a finished (vented) "Mid" Marty (8.3 cubic feet) with a UM-18 would be?

You can model it with those specs, but it should still be within 1 dB or so of the figure listed. That is a negligible difference. I used a different driver in a 10+ cu. ft. box, and it modeled within .34 dB of spec.
