Paradigm Soundscape. Just cable box to bar to sub through wireless output.

Could it simply be that the sub is too small for the room?

Is the subwoofer actually outputting audio (i.e. is it paired correctly with the soundbar)? I ask because your graph looks like the sub isn't even on.

Sub is def on. I am going to play with it some more today. Maybe I am doing something wrong in REW. I went to this page- https://www.minidsp.com/applications...setup-with-rew and on step 4 I used the speaker cal selection to set level on the sound bar and the sub selection to set level on the sub.

I am also going to try moving the sub around the room.

Make sure the SPL meter is set to "C" and "S" (slow).

Also, make sure you are using CH3 (center channel) Output in REW (if you are using HDMI). Do NOT use CH4 (LFE) as that will output 10dB higher than all other channels (and may explain why your sub is so low).

Just got mine this afternoon - I was like a kid in a candy store, totally got Fed-Ex grime on my nice pants and shirt b/c I couldn't even take time to change before I carried it inside and opened it. So far I've only had time to drool on it in the box...thankfully it's still wrapped up.

Will get it hooked up tomorrow morning (or tonight...who am I kidding). I'll post some real pics and impressions after I get it placed and running, then some measurements after someone walks me through REW etc.

So I spent the last couple hours running scans- beside the loveseat, facing forward and to the side, next to the main couch, forward, side and backward, and under the tv, facing me, and to each side.

....and the graph with the least nulls?....

Under the tv facing forward.

Currently running the antimode now to see how it cleans up.

I still haven't had a chance to install the V3600 - got home a little early today, but the phone calls and work emails wouldn't stop. I'm hoping to get done tomorrow early, so i can for sure watch a move on it tomorrow night. It's a shame to have something so beautiful just sitting in a box.

I'm curious, does anyone use a y-connector on their V3600? On the SVS units, it boosted the gain about 5db, so not sure if this has the same effect on the V3600I.

Hello

Just a short note to say hey to all my buds here, I really miss being here and posting to all the comments and introducing myself to all the new folks joining the Family. I'm going to try and be a regular again, still need time to recover from some new ailments which prevent me from doing much of anything, getting older has it's downfalls.

I've learned a few things by getting older, "you don't get old by being a fool", fight the good fight and finish the race". Each day on the green side is a Blessing. Take care my dear friends, I just had to stop by and let you all know I'm still kicking............

Best Regards To All, Jeffrey

This looks much better than your previous one! Good work, sir. It's much more consistent, which is what you want aim for when calibrating. It sounds like your room is quite challenging and if you wanted more smoothing, you'd likely have to end up adding another sub in a different location. If you're happy with the results, that's all that matters.

Now that you've posted some graphs, what are your thoughts on the sound and output? Surely, it must be more enjoyable than a naked soundbar, after all!

@ahblaza , it's good to see your name again, Jeffrey! Though the last several pages in this thread have lacked your helpful and thoughtful posts, you were most certainly not forgotten among us regulars.

Wishing you a speedy recovery,
Travis

Question for the REW savvy here...

Looks like CSL is out of the UMIKs for a while, I guess they are taking pre-orders now, possibly shipping in another week but who knows for sure. I can order right now direct from minidsp, but is there an appreciable difference that makes waiting on the CSL mic (plus the extra $25) worthwhile? I know it's probably a relative question with no definitive answer, just looking for opinions. Thanks all.

I may have one for sale that I bought right before Xmas. Decided against using REW and will use Omnimic instead. I don't think you can send PM's, but you can email me at my username here on AVS @ver izon.net if you are interested. Was actually thinking of returning it, but I am not sure if they accept returns.

As far as I know, the mics from CSL are individually calibrated, where the ones from miniDSP have a generic calibration file that is for a batch of mics. The ones from CSL will be more accurate, how much of a difference it would make, I don't know.

What are your impressions? Also, is a 3-way cab design like that also inert like a dual-opposed S3000i?

Well I have finally taken the leap. I just put in an order for my T18HT with Anti-Mode 8033. Can't wait to hook that monster up and see what it can do.

For the past year and a half I have been planning on doing a 4x18" IB DIY build and then the wife finally put her foot down...no holes in her ceiling. So Now I'm going the next best route, a monstrous 3x18" setup in the room Surprised I got her blessing for that.

This is will actually be my first true high quality subwoofer I have ever owned. The only other subs I have had were only 8", one Definite Technology with the Cinema 600 setup, and one Klipsch my brother gave me after he upgraded to a 10". I am sure I will be in for a treat with this.

Hahaha, I had to chuckle at "first true high quality subwoofer". First of all, you chose very wisely, so good job! Outside of some pretty crazy and intense DIY'ers, there really isn't much of an upgrade path that I know of. Second, I would try and not let her see the sub in its packaging or on the pallet it ships with; it may sway her decision if she was on the fence about it. When I helped a friend move his V3600 into his house, his wife looked sick in the face when she saw that it filled most of my truck bed in my F150. I lost count of how many times she said to him, "You are #!*$ing nuts!"

Please be sure to stop back and let us know your thoughts and impressions! That is one of the coveted subs from PSA I have yet to audition.

Frustration with REW.

Every time I use REW I have to spend at least 30 minutes to get everything working in order to take a measurement. I have never been able to get the asio drivers working to allow me to pick a channel to graph, I only have 2 channels available so I have to turn Amos on/off or unplug speakers. The last 3 times I have tried and am not able to get any audio out of my laptop to the receiver.

Last week was the final draw, spent an hour going over everything in AustinJerrys guide and could get no output from the laptop (even though playing a blu Ray disc produced audio). Dropped about 50 F bombs, a couple C bombs, almost punched my laptop screen and yelled at my daughter when she came down to ask me to play Disney infinity with me. Even tried on another laptop with no success. Was trying to do the sub distance tweak. Gave up on REW and tried Omnimic and had the sub distance tweak done in 10 minutes.

I am sure I am doing something wrong in REW but just don't have the time/patience/knowledge to fix it.

I can gets sweeps/graphs running in Omnimic in under a minute and it just works every time.

Much better! Great job!!

However, a couple things:

This is obviously a sub only measurement (you either used CH4 out of REW or you bypassed the soundbar somehow). We need to see the sub+soundbar to see the interaction between the two, especially over the crossover point.

You should have 5dB steps on the left hand side of the graph. If your monitor's resolution isn't high enough to provide that at the recommended (55-105dB) limits, reduce them until you get 5dB steps. This just makes it easier to compare graphs.

You must have a fairly large room judging by the sharp drop under 20hz, is this correct? If so, why a sealed sub??

You have an Antimode with a soundbar??

Back when I used to have XS15s, my dog used to lay beside the sub just like Bubba there....since I got my T-18s she does indeed "run for cover". She hides in the bedroom, panting and trembling...I actually feel bad for her, but I'm sorry dog, I'm not toning it down any time soon.

This is obviously a sub only measurement (you either used CH4 out of REW or you bypassed the soundbar somehow). We need to see the sub+soundbar to see the interaction between the two, especially over the crossover point.



You should have 5dB steps on the left hand side of the graph. If your monitor's resolution isn't high enough to provide that at the recommended (55-105dB) limits, reduce them until you get 5dB steps. This just makes it easier to compare graphs.



You must have a fairly large room judging by the sharp drop under 20hz, is this correct? If so, why a sealed sub??



You have an Antimode with a soundbar??

Yup, that is just the sub right now. Playing with that first before I mix in the bar.

In that chart, I am using a lift function at 25hz which unfortunately forces an infrasonic filter at 15hz and chops the lower end.

Yes big room, yes antimode on just the sub off soundbar.

You are going to laugh- I just bought a antimode dualcore to bring the bar into correction as well. It opens up a lot of options- PEQ, lift, tilt, etc. Should help balance the bar to the sub better than I can do alone.
