Why Is My Subwoofer Not Hitting Hard - PB1000Pro

[liverpool_for_life]

More (bigger drivers, beefier amps, multiple subs etc) simply need bigger rooms to shine.

Not true. As long as the size of the sub doesn’t severely constrain placement to a terrible location for effective transfer of energy to the listening area, bigger drivers (more detail and greater extension) and beefier amps (headroom and greater SPL capability) are always welcome. As are multiple subs. Especially for small rooms.

What’s the point if you can’t turn the dial all the way up to unleash all that power when the small room cannot take it.

As above, you’re likely underestimating the importance of headroom.

You might get a smoother bass with two subs, but I guess the law of diminishing returns would set in much earlier in this case.

If one has flexibility with positioning of multiple subs and has the tools necessary for their integration, a more consistent response over a larger area of the room is a significant advantage. IMO, when it comes to bass reproduction, one is much more likely to hit the limits of one’s wallet before hitting the limits of audible gains.

Hi yes from Avenue Sound in Mumbai, Navi Mumbai. I would prefer not to comment on any brands because I think it would be unethical to come on this forum and promote any specific brands which we may sell. I think the forum has rules against that also. I hope you were able to get the sub sounding how you wanted it.

Forget about specific brands, are you guys a legitimate business is what i want to know since nobody picks up phone calls on the numbers you've mentioned on your website.

Perhaps a little less time giving advice on HFV regarding unspecific brands/topics and a little more time attending to customers vis-a-vis the brands that you actually cater to?

Worst part is even their own dealers complaint about them

I think the thread is sidetracking here. Please focus on helping the OP in this thread. Avenue sound discussions can be done over PM or on a separate thread as deemed fit by the moderators.

Thanks for the clarification- agree about the headroom. I had replaced the L&R of my AVR with the Parasound A21 (250 w/C), and the difference was remarkable. I am yet to see how far my gear would go at high volumes (17 x 10 feet is my room size, 8 inch floor standers, 15 inch sub). Having said this, would introducing an AV pre-processor improve the overall sound quality noticeably? I think it would; but not sure to what extent. I have never used an AV pre-processor before. I am thinking of picking up a used one, provided I get to find one.
Thanks.

Wonderful. Enjoy!

Cool. There's a good chance you'll run into the limits of your room (if untreated) as you turn up the volume.

IMO, the biggest difference between different brands of processors/AVR's is the room correction software. So, I don't believe there's going to be much of an audible effect between using the pre-outs of your AVR vs a dedicated pre-pro, if the room correction software in both units is the same.

Pardon my ignorance, but is the room correction software the only differentiator for a better sound? There are pre-processors that cost the price of a car, but have the same room correction software that a mid-level AVR does. Wouldn’t you think that the pre-processor is doing something more or different than the AVR? In this case, perhaps I am paying more for the pre-amp stage, and therefore expect better sound?

I did say "the biggest", not the only.

What differences do you think arise from using the pre-outs of an AVR vs using a dedicated pre-pro? For simplicity, assume the same manufacturer and similar class (identical features, only difference being in-built amplification vs not). If your answer is better parts and circuitry for the extra money will automatically translate to not just measured but actually audible differences, fair enough. Color me skeptical, though.

In this case, perhaps I am paying more for the pre-amp stage, and therefore expect better sound?

With the caveat above, we can expect all we want, but are the differences real, and more importantly, audible? My bet is no. As always, YMMV.

If you're talking about different classes of processors (Trinnov Altitude vs Anthem AVM 60 in my case), my subjective impression is that the Trinnov is comfortably ahead of the Anthem. And this is before room correction. I definitely wasn't expecting this, so it wasn't expectation bias. So, I'll grant that paying multiples of what I paid for my old audio processor has led to better sound for me.

Though, I did audition the same sub at top gizmos noida. I was impressed with its performance, that's why I chose to buy it.
Also, been following this group since long and after innumerable positive reviews I decided to purchase one.

I don't know what's wrong with my sub.

do you have treated dedicated room or normal bedroom

 

[Supperrabbit]

Try a subwoofer crawl test! Place the subwoofer where you usually sit, then play a test tone or a bass-heavy track from YouTube. Get down and move around the room, paying attention to where the bass sounds the strongest. Once you find the best spot, place the subwoofer there and test it again.

A very old method but can give you some inputs . You will not need any microphone of anythings as such

 

[hardcore_gamer99]

Just buy dirac live and leave this hassle. It will be night n day difference

Hello Guys,

I am pretty happy with the setup I have but I feel that the bass I am getting from my SVS PB 1000 Pro is not adequate. It's hard for me to describe but it feels so low, since most of you here are home theatre enthusiastic so you’ll get it.
That punch or thump on my subwoofer is missing, like when watching any fighting sequence, I don't feel that tight hit sound we usually get in the theatres. Another example is the same tight sound produced by a bass drum kick. My ears are expecting the perfect punchy and powerful bass that you get from an ideal subwoofer like PB1000.

I have seen many of you had previously mentioned on a different thread about how powerful PB1000Pro is, many have set the sublevel to -11db yet sub has its adequate impacts. I have kept it in -4db on avr and bass is almost non-existence. On SVS App its -10db.

My sub is set on LFE with a Crossover frequency 120Hz. And mains are set to 80Hz, surround and atmos speakers are set on 100Hz.
What can be done to fix this?


AVR - Denon X3700H
Front Speakers - Dali Oberon 3 Bookshelves.
Center - Oberon Vokal

This is problem of acoustics in room particularly seat positioning.
You have to change subwoofer position or your seat position.
This can be done by multiple techniques. As a newby to try , check out subwoofer crawl method . Please visit below link for practical method.

If the subwoofer is weak in midbass frequencies, no matter of sub crawl, dirac live can rectify this issue. Svs are known to go lower but weak in midbass.

Indeed, I had a demo before I purchased this model, so I am wondering where I am lacking. I now have upgraded to four subs of the same model, yet I'm still lacking power and punch. I read somewhere that increasing a mid-bass PEQ filter will boost the mid-bass region, leading to subjectively more punch/impact.

Possible to share the settings on the subs and avr?
