Remove low-pass filter on the sub-out

[Rexicle]

I have an RSL Speedwoofer in my listening room that can easily play down below 20hz with corner loading. I would love the 30hz lower limit of the sub-out to be removed if this feasible.

On wiim app, if you set let say 50hz above 50 goes to speaker below that to the sub. From here, it’s on your sub how well it can go deep. Here I would set up both sub and speaker. Set your desire crossovers, adjust the sub volume without calling attention. Run auto timing then after that run rc and set to flat that is if you’re aiming for flat. In my case I get better sound on range 20 to 500. Play on different range and see which one would sound best on your system.

Hopefully other members can offer some sound advice.

Funny!!

From the sub-out control screen you're able to set a crossover between the speakers and the sub anywhere from 30hz on up. See the screenshot in my post above. It indicates pretty clearly that it's outputting 50hz down to 30hz.

As others have mentioned, this is not what's happening. Even if it was, this was a high pass filter (letting everything above 30 Hz pass), not a low pass filter. But again, this is not how it works.

From doing room sweeps I can confirm that my sub isn't outputting anything below 30hz. I'd like that lower limit to be removed.

It might just be your sub implementing this high pass filter. Are RSL still in business? I don't find any website. Which exact model do you have?

I was using a Umik-1 calibrated mic with the HouseCurve app on a Macbook so it should definitely be able to pick up sub 30hz.

Nothing against HomeCurve (on iOS and iPadOS devices) but on your Macbook you should rather be using Room Equalization Wizard.

RSLspeakers.com is their URL. They're alive and well and have 2 of the best budget option subs around these days. I have the 12 in my HT room and the 10s Mk 2 in my listening room/"parlour".

I'm fairly certain that it's either

a. my sub is in a bad position in the room - if so I'm not sure I can change that as the room has limited locations for a sub or
b. HouseCurve. I do have REW and I've used it in the past for my HT room. I'm just very rusty on its use and I'll need to brush up on it before I run some sweeps.

Long and short of it - please consider this request closed - user error. Thanks for the lively discussion!

I tried putting my BK sub in the corner and didn't notice any extra boost when doing the room correction sweep. It's back between the speakers now. It doesn't really go below 30Hz either.

I suspect it is my unfamiliarity with the HouseCurve output that is the issue here and not the Ultra.

What sub are you using and do you have a sweep you can share?
