I'll get on that in the morning.. If I turn up the crossover to 120 it fills the hole but, in doing so it make 300Hz about 6db higher than it is now.

I have a servo sub wiring diagram.

Houston, we have a problem. I've been messing with the servo sub wiring for quite some time. To my eyes it's correct but the amps say no go when I turn them on. I can run one but if I try and run both I get this loud deep growling sound. Anyone know whats up with this? I'll keep searching.

Sounds like the servo coils are wired backwards. My sealed unit did that when I wired the servo coils in reverse phase by accident.

I'll give that a try thanks

Once the subs are wired correctly, play with the crossover setting to get everything as flat as you can. It shouldn't be creating that much noise around 300Hz but maybe there's a harmonic there since the room already has a mode at that frequency. I think you might have to find some kind of middle ground.

Thanks fellas. I've finally,,,,,,,,,got the sub wiring firing on both sides. Long story short the servo wiring was a shambles.

Measurements when my wifes heads out. Lot's to do today nut this is priority and she understands.

Hobbsmeerkat, I owe you.

I'm on it in the morning. Busy day and just sat down for my evening Whiskey.

I love a good rye. Cheers!

Wedgies measured.

need that 70Hzhump gone now

mkane · « **Reply #150 on:** 14 Nov 2021, 07:33 pm »

Colors to go with it.

mkane · « **Reply #151 on:** 14 Nov 2021, 08:02 pm »

Here's Super Minis. Still a bit of work to do with both.

Those measurements are great! For the 65Hz hump, use the EQ on the sub. Put it at 65Hz (or where you think that would be since it's not labeled). Then set the bandwidth to the minimum (or close to it since the 65Hz hump is pretty thin). Then turn the gain knob down around 3 or 4 db. Play with these dials until you get the more flattened out without causing other problems.
Maybe you know this but the "bandwidth" knob will determine how wide your frequency cut (or boost) is. For example, if you turn the bandwidth to "minimum" then it will only affect between 60 and 70Hz (or something like that). At Maximum it will affect a much larger spread of maybe 30 to 180Hz. So, you want to set it at the bandwidth that matches the size of the mode around 65Hz. I think it should be much closer to the minimum side.

Thanks DannyBadorine. Didn't have a clue what the bandwidth dial did but I do now, thank you.

EQ on the sub would be the frequency knob? It's now @ 60Hz.

BW is in the middle

Gain is @ +3. Can't take any measurements until tomorrow after I get some wood split.
Think I should turn some knobs and just listen? Awesome.

DannyBadorine · « **Reply #154 on:** 15 Nov 2021, 01:34 am »

Get the frequency closer to 65Hz since that's where your node is. You want to be as accurate as possible. The gain should be negative. You want to pull down that frequency that is too high. I would start at -3, but you might go lower than that. Take a measurement and post it. Once you get that big node down then you're going to be in a really good place. Enjoy the whiskey!

Today Super Mini SPL.

Hobbsmeerkat · « **Reply #156 on:** 15 Nov 2021, 09:14 pm »

Now that looks fantastic!

DannyBadorine · « **Reply #157 on:** 15 Nov 2021, 09:31 pm »

OK. Now take pictures of all of the settings and locations of speakers!!! Trust me on this! That frequency response looks great!!!!!!! I'm guessing that it sounds great too now.

mkane · « **Reply #158 on:** 15 Nov 2021, 10:20 pm »

It does sound very nice. Full, imaging spot on. Low end is the best it's ever been and there's been lot's of speakers through this house.
What's causing the dip @ 160Hz?.

Is the bump between around 10k to 20K normal in the NX line? I have the same bump when I measure my NX-Otica's and thought I may have messed up the crossover somewhere.
