Did Adding 2 Subwoofers Fix my Bass Issue???

[@nonametofame]

I really appreciate your honest, non hyperbolic, straight, objective videos. You point out the good and the bad and never wax poetic about how "amazing" everything is. It's quite refreshing. Keep it up!

[@TerminatorJuice]

Thanks man, I really appreciate it!

[@miscreant1739]

I think you'll enjoy it a lot more if you bring back the house curve... with the bass flat from the mains all the way down to 20hz it probably sounds very lean. i use a +12dB gradual rise that starts around 130hz and peaks around 40hz. If you have it flat and then just increase the sub level things will sound muddy but the gradual rise prevents that.

[@TerminatorJuice]

I don't doubt that that is good advice, but I can't go back to having to lower the volume during explosions or peak bass moments because of the large db difference between the subs and my mains. Also I'm not really a fan of tinkering with settings, and/or taking measurements, so I'm in talks with Andrew from home theater engineering about having him calibrate my system the next time he's in the US.

[@miscreant1739]

​@@TerminatorJuice Having a steady and smooth rise like I'm describing doesn't lead to a peaky sound because you need more SPL at lower frequencies to sound equal to less SPL at higher frequencies. If you try to fill a null by dumping a lot of power into it that can definitely lead to a peaky and unpleasant sound in my experience. I can turn up my system pretty loud where the low end bass is over 115dB and it still sounds great. If you're satisfied with what you hear now I can definitely understand not wanting to mess up a good thing - it's always a lot of effort to adjust things. I'm not familiar with Andrew but if you think he can help I'd definitely recommend it. There are also several guys that are willing to help remotely, some probably for free.

[@TerminatorJuice]

@@miscreant1739 I didn't really have any boosts going on with my EQ, because I heard that isn't worth trying to fix a little null that you ears more than likely aren't even going to notice. Also, Andrew is a 20 plus year certified calibrator, and seems like a straight shooter, so I'm going to talk with him and see what he says. Here is a link to one of their YT videos... kzbin.info/www/bejne/gXTPga2prKqpZ6c

[@almiragustin2262]

Like you channel :). Iv also got -10db dip on 70hz. Also planning to get a 3rd at the rear and hope it fixes the issue.

[@TerminatorJuice]

Thanks and Good luck!

[@AeroDude73]

I would think most people get or might get better results (& also from reading/listening to many HT Veterans more knowledgeable than I), with the subs in Opposite corners. My two Hsu subs are like that & Slam. One in the right front to the right of my TVs stand, inside my Right Polk RTiA9. The 2nd one is in the rear Left corner under a coffee table. - Hope you’re successful with your results!!

[@TerminatorJuice]

I tested that with the Sealed subs, but lost the tactile bass that the ported sub provides, so that wasn't going to be worth it to me. So my final configuration is the two sealed subs up front and the ported sub in the rear, and that provided the best overall experience for me.

[@AeroDude73]

@@TerminatorJuice nice 👍🏼

[@FrankieKennethL]

I’m absolutely the same way regarding optimizing for multiple seats. I know it’s an unpopular opinion, but I don’t host anyone often…I prefer to optimize my sound experience to my MLP with the wife to my right being great also. I don’t need even responses across multiple rows I ran my initial setup w two SB 3000s and loved it. I’ve recently upgrade to two GSG 21 yet to be built 😮

[@audfrknaveen2256]

Can you generate a waterfall graph.... Just to see the decay time for bass ...

[@TerminatorJuice]

I could the next time I have the mic and everything setup... But I'm going to take a break from tweaking and just enjoy the room for a while.

[@audfrknaveen2256]

Please post your subjective observations for music and movies as you enjoy 😊👍

[@TerminatorJuice]

@@audfrknaveen2256 I don't get caught up in tweaking settings, so I only do it when I make a major change or additions to my gear...which doesn't happen very often. I'm just a guy who loves to listen to music and watch movies, and wanted a dedicated room to do that in. I'm not really the type of guy who gets excited about the gear or feel the need to upgrade all the time, so I'll probably take a very long break before I do anything major to my room.

[@jrep88]

Did you time align the subs with your minidsp before doing EQ? Also I get great results by flattening the sub response out to a frequency double that of the crossover.

[@TerminatorJuice]

Yes I did... and I'll try your suggestion out the next time I mess around with REW! Thx

[@jrep88]

You should be getting more bass than you can handle with those three subs.

[@TerminatorJuice]

@@jrep88 I have cement floor, so it's not that clear cut. Lol

[@Lowkey_nxthxn]

You should get SVS pb16 ultra then problem solved lol

[@TerminatorJuice]

It still wouldn't fix the null at 70Hz, because that's just the fault of the room, but I'm sure it would add something... Lol

[@Lowkey_nxthxn]

@@TerminatorJuice you should be able to fix the issue with a mini dsp or room Direct live.

[@TerminatorJuice]

@@Lowkey_nxthxn All the professional calibrators that I've heard discuss this topic say NOT to "fix" nulls by boosting those frequencies, because it takes a ton of energy to do so and the results aren't worth it. It just makes you measurements look smoother...

[@AeroDude73]

Do you own Edge of Tomorrow/Live Die Repeat on Blu-ray? The opening seconds are Extremely Low & should give your room a serious workout.

[@TerminatorJuice]

I have the Bluray and I just recently picked up the 4K Steelbook(which I know doesn't go as low), but I haven't watched it since I did the latest EQ with REW.

[@AeroDude73]

@@TerminatorJuice look forward to hearing your thoughts 💭. 👍🏼

[@smurfie8412]

Just go all ported my dude, get the best you can afford so you won't have any what ifs

[@audfrknaveen2256]

How is the bass subjectively now ?? Is it tight and accurate with good transients for music?? Let's say drum beats in music, how punchy and accurate they sound?? And secondly how good is the tactile bass for movies ??

[@juleocan]

have you thought of putting that PB1000 right behind your seat for nearfield tactile response? i have a monoprice monolith 10 sub and could not get that deep bass i was looking for but once i put the sub nearfield right behind me i got that punch in the chest sound i was looking for. my monolith sub is sitting aprox 6 inches from the back of my couch seat and it feels good. ive read to have the distance between the front of the sub and back of seat no more than the diameter of the woofer driver to get the best response

[@TerminatorJuice]

I thought about it, but only for about a minute, because it's not practical to have a subwoofer blocking the path to my back room.

[@audfrknaveen2256]

By any chance did you try very near field? Like keeping the sub right behind your chair not more than 10-12" distance.

[@TerminatorJuice]

I wouldn't try it because I'm not willing to have a subwoofer there all the time, and I don't want to have cables lying on the floor.

[@audfrknaveen2256]

@@TerminatorJuice ya ya completely understand 👍👍👍

[@fernandoayllon6376]

I think you got quite an upgrade there :) but you should be able to get a flatter response if play around with some manual PEQ filters after loading the REW filters. If I understood properly , you modified the subwoofer EQ to avoid the 60hz peak when playing mains+subs. If so, don’t do it cause your are messing the LFE channel response: it won’t be flat. If you don’t have the ability to tame that peak in the front channels via Audyssey or a second MiniDSP, let it be. In my room I have two 12” sealed subs, after level matching and time-alignment, I ran Audyssey and then I ran REW and did PEQ to get a flat response on the subs. I also got a peak in the 80hz region when playing sub+mains but I happily live with it. As per AVS sub calibration post, I boosted the subs by 9 dB, this way I got a nice tactile response never experienced before that left me with a big smile. You could try a second config tab in the minidsp and see how you like it.

[@brnmaull]

Just going to throw this out to you. Not sure if you thought of this yet. I know you said you like ported boxes and I know that's what you got in the back of your room. You also said you wanted to stay under 16 inch high. You can always get the pb1000 and put them on there sides.

[@vmd1293]

Do you have emails? If you don't mind I'd like to ask you a bit about how you generated your graphs in REW

[@TerminatorJuice]

There are about 50 videos on REW on YT, but go watch The Home Theater Gamer's videos on it, and you'll see how it all works.

[@frederickwilliams3319]

Are you running an AVR or separates? Have you considered an AVR or processor with Dirac (if you don’t already have one)? I keep hearing it makes a huge difference.

[@TerminatorJuice]

I have a Yamaha AVR and separate amps for my Atmos speakers. And I don't put much stock into room correction to be honest... But seeing that they are starting to allow you to see the measurements and tweak the results to your personal tastes, I'm way more interesting in the potential with room correction in the future.

[@frederickwilliams3319]

@@TerminatorJuice Yeah, I’ve heard really good things about Dirac. I ordered the Onkyo TX-RZ50 because of Dirac integration. It’s back ordered, and I’m still having “second thoughts” about Onkyo (with Dirac) VS something from Yamaha, Denon or Marantz.

[@miscreant1739]

@@frederickwilliams3319 I have an Onkyo TX-NR7100 with Dirac and it has been great for my subs. You can really boost the low end and bring down the mid-bass and get the curve looking very smooth without a minidsp.

u need to keep trying... try 8 subwoofers or 12..... or go industry standard and use 24 subwoofers...
