    Great job on nearfield subs, the best I’ve seen or heard on TH-cam. One question: have you tried your PSA subs vertically nearfield and how much of a difference would that make over having one driver lower down? I would guess they’d be more tactility in the abdomen and chest, but since I’m in the planning stages of a home theater build, it’d be useful information for me.

    I put by duel Klipsch THX ultra 2's behind my couch, mainly because my room is very small and they won't fit anywhere else, but i've have liked it because I don't need to turn them up very much to hear and feel them and my girlfriend doesn't complain about the house shaking, I also have them on the SVS isolation feel, so they don't transfer much in terms of vibration into the other rooms. I know that's not what you thinking about, but for those of us who have to keep it quite its a great way to enjoy your system without disturbing others.

    Question about - Distance setting - related to multiple-subs + Locations ( IN ROOM )
    - when using a Single LFE / Subwoofer output, while using 2 or more subs in different locations. - Basically if I'm using a single .1 LFE output, and I have the distance setting set to - for example 9ft how will this effect a nearfield(next to recliner) sub on the same .1 LFE output, I Don't think it will work correctly as the LFE is set to 9 foot distance. (meaning the bass will be like a big blurr of sound Smearing(?) I think is one of the terms, like mixed bass and response and inaccurate.
    The nearfield subs on the same connection / LFE out will still be set to 9ft away when in reality next to your chair / recliner they're maybe 3ft~ away. -
    - The way I see Multiple-subs; some far away, some close for more tactile effect working is if you have 2 or more LFE outputs. Would you agree? -- I Think with the receiver / preamps that have 2 or more, you can set different distance and other settings for each of the LFE outs.
    The info given gave me interest / motivation to set up 2 of my older 10 inch subs (Much less bass extension on them) next to my recliner, while having my M-10 V2 ( MONOLITH (which can go down to 16Hz/17Hz) ) sitting in the current original position front left corner. Then I realized setting up the 2 subs next to my recliner on the same connection does not make sense per the distance setting. I Tested it though anyways, it does feel different, but does not sound right or its best.
    let me know about the whole LFE + DISTANCE setting thing, related to single LFE, and what you think about this.

    Great video! Question...If your front 2 subs are ported, should the subs you choose for nearfield be ported as well? Also, should they be the same size as your main subs you already have? I have 2 12's in the front of my room.

    • @SpecOfTech
      @SpecOfTech  ปีที่แล้ว +1

      It is always easier to integrate identical subwoofers. It isn't impossible to integrate different enclosures styles (ported/sealed), but it does take more work and most likely a minidsp. The same thing goes for different size drivers etc. This is assuming you want proper integration with a flat response.

      Not really. The reason being is that nearfield really neuters the low end your would experience in your seat. If you don't care about the low end though, going nearfield with 1 subwoofer would still shake your chair and make it feel like you have 8 subs in the room haha.

    You just made a comment that blew my mind about the near field drawback #1 which you lose low end frequencies when near field. Why in the world is that? I’m experiencing that same issue with my PSA TV2112M dual subs behind my theater seats. I also have dual PB16 Ultras at front of theater. Sounds like the PB16 subs dig wayy lower thab my dual PSA sub which boggles my mind. The PSA subs are way more powerful and go down to 10Hz but i get mostly mid bass from the PSA Subs. Can you please tell me why this is before I lose my mind lol. I thought something was wrong with the subs or better yet, I was doing something terribly wrong. Please help me understand
    Thank you brother

    • @SpecOfTech
      @SpecOfTech  9 หลายเดือนก่อน

      I don't fully understand it myself, but I believe it has to do with room gain. When your subwoofer is placed behind your seating and away from boundaries (walls), you lose out on room gain. If it is placed behind your seating, their could also be some absorption happening, which will exaggerate the effect.

  • @Ibhenriksen
    @Ibhenriksen 2 ปีที่แล้ว +1

    For near field listening the best place is in the center, below the center channel, in most cases. Each subwoofer varies.

    • @SpecOfTech
      @SpecOfTech  2 ปีที่แล้ว +1

      It would also greatly be dependent on the room. Each room has different room modes, so best placement would be to measure with REW and find which placement gives the best response.

      Hey man, thanks for watching. If your subwoofers have a line in and a line out, then you could daisy chain the subwoofers together. If they do not, you can use an RCA splitter like the one in this link amzn.to/3GrVOCQ.
      Keep in mind that your room calibration software will treat the subwoofers that are tied together on the splitter, or daisy chained together as 1 subwoofer.

    I ended up upgrading from my V3600i to a PSA T-18 which is 3 x 18" sealed unit with 6000watt amp. It's better in terms of clarity and punch as well being far more musical but I was surprised I hit a sealing with movies so quickly. I also don't feel it gets as low as the vented V3600i did which is strange since the T-18 is rated to go lower. The windows would rattle at 12Hz with the V3600i but I don't hear them with the T-18 which also feels less tactile as a result. I run the T-18 near-field between two recliners, but yeah, just not getting that teeth-rattling sensation that the V3600i gave (although I was left wanting there too!). Maybe a second T-18 will fix it?? I don't really want to go through the cost (and hassle) and getting another one of those beasts in the cinema if it's not going to give me what I'm after tho...but surely 6 x 18"s with 12,000 watts should do the trick!?

    • @SpecOfTech
      @SpecOfTech  4 ปีที่แล้ว +1

      My first question is, have you done much to optimize the one that you do have? Have you ran REW sweeps, played with gain, played with placement etc? Have you talked to Tom about getting the most out of that subwoofer? If you have done those things, here is my advice and what I would personally do. If you are not happy with 1 of them and you feel it is lacking, I wouldn't buy another. You are just setting yourself up to be doubly disappointed lol. Adding a second will definitely add to the overall DB in the room and will smooth out the response etc. But if you have 1 near field and it isn't blurring your vision, you may want to look at upgrading into a different subwoofer, and yes maybe you need to look at ported if that was more impressive to you. Looking at the charts on PSA, the T18 seems to peak at the midbass frequencies. I think you are right, what you may be lacking is a more powerful low end. It doesn't look like the T18 is even for sale anymore. My suggestion is to take a look at the JTR offerings, specifically the JTR CAP4000. They are well known for their powerful output, especially in the low end. My dual PSATV3612's have some pretty great low end and some awesome mid bass, but the CAP4000 has quite a bit more. As it should since it is quite a bit more $$ than my TV3612's. Another one to look at would be the little brother of the CAP4000, the CAP2400. If you don't feel like going the sub route, maybe look at some transducers or the boss platform. Cheers man, and good luck.

      @@SpecOfTech Appreciate you taking the time to give some advice mate! I actually have not run REW on it yet (know any good guides?) but I have run Audyssey numerous times and dialed the gain in with level meters and by ear...like I say I'm happy with it overall it just doesn't have that tactile response that you'd think 3 18's would be able to provide. I have not spoken to Tom no (any tips on best way to reach him?) and yeah the T-18 is an older model but again it's all I could get hold of here in Australia - it was PSA's prior top-of-the-line model though so it should still be a crazy good sub. Ported subs don't feel tight or musical enough for my liking but they definitely offer that bang for buck! I was thinking along the same lines as you in regards to buying another (don't) but maybe having two would pressurize the room properly and give me that tactile response I'm after?

    I don't disagree at all, but I'll play devils advocate and put a vote to bass shakers as a viable option. In my experience, they give the same or even better effect at a typically lower cost. I have one 18" Aura 1808 sub (DIY Wilson Audio sub) (yes it's ancient but still very near top end sub). That was great but I wanted more, so I added two mid-lower end 15" subs from Parts express. I was getting good room pressurization, but as you mention in you video, when I turned up the subs to get good tactile feel, the bass was unbalanced and overpowering when it shouldn't be. I removed the two low end 15"s and I added two Clark Synthesis TST209 shakers, one on each end of my couch and two TST239 shakers, one on each of two recliners. I wired them series parrallel to a 350watt@4ohm dedicated subwoofer amp. I adjusted the crossover and amp level so that now, even at modest listening levels I get a subtle tactile effect which is nice, you don't have to have the volume turned up loud at all to enjoy the experience. And, well,, the REAL experience is when watching action movies of coarse and you get the full effect at reference sound levels, and the 350W amp seems to be plenty. Plus,, they're virtually unseen so if you're into a minimalistic look, they're great, as well as they have a WAF of 9.5 out of 10. The only complaint she could possibly have is that you spent some $$ on it.

    • @SpecOfTech
      @SpecOfTech  4 ปีที่แล้ว +3

      Absolutely, bass shakers/transducers is a great option as well for tactile bass. A near field subwoofer is just a way to increase the bass you feel and tactile response without purchasing anything additional, assuming you already own a subwoofer or 2 ;). Sounds like a pretty sweet setup brother! Those are definitely some strong arguments for the transducer route. I have considered going with a boss platform as well. But right now my PSA TV3612 behind my MLP provides amazing tactile response, and just like you, I do get some tactile feel even at low volume. Regardless how you get that tactile response at low volume it definitely helps with immersion when watching movies or playing games at low volume. Once you go tactile you can't turn back lol.
