And big

Very interesting, thank you for your comment. How far do you have them off the floor?

@@AxiomHomeTheaters I am using six 12" powered ported subs in a 2 channel system. Two subs are 12" off the floor on custom made stands weighting 90 lbs each with fine grade sand in the legs., the second pair sit on top of the first pair and are 33" from the floor. The third pair are on separate stands and both are 66" off the floor. All subs are transmission line from the same series from the one company. Hard to tell the subs are on most of the time until an explosion or something dramatic happens in a movie and then the subs come alive and the sound pressure hits you in the chest. Personally, I will never go back to putting subs on the floor. I am building my system into a surround sound, either 5.1 or 7.1 I have ordered a center channel speaker with leather baffle that measures 37" wide, 11" high, 16.5" deep. It uses 2x 7.5" Satori woofers, 2x 5.5" SB Acoustics NRX midrange drivers and 29mm wave guide tweeter, this center matches my two large bookshelf speakers to get a seemless front sound stage image. Everything is custom made when I order and are not off the shelf items and costs more and is taking me longer to save money but the sound is simply incredible and worth the wait. Not sure how but if interested I can send photos which might help others decide if they would like to do something similar.

@@lorindamikaela Very interesting. I have done a lot of research into multiple subs and the impact on room acoustics, but not loading the room vertically like you are doing. Certainly something to explore!

@@AxiomHomeTheaters While subs use the floor to their advantage as boundary reinforcement, you lose some of that by lifting the subs off the floor, what you do is turn the gain up slightly to compensate or add another sub to the equation. All my subs have the gain set between 1 and 3 that's all and the pressure they develop in my room actually vibrate the windows if a big enough explosion happens. The plate amps in each sub are only rated at 350 watts which is "more" than enough when using multiple subs. We use speakers at different heights in our home theatre setup why not do the same with subs ??? Yes subs are omni-directional "BUT" you get a grand sense of scale when subs are placed at different heights and placed correctly. I've been exploring this for 15 plus years through trial and error and I am really happy with my current setup. Example --: Have you ever experienced a fighter jet flying low over-head and you feel the deep growl and roar and the pressure that is generated from that jet engine over-head which almost takes your breathe away and it gives you a fright and you duck your head but it also brings a smile to your face -------- that's what I experience in my setup. It's life-like and feels like reality and you live that experience all over again. It's not about volume but realism. My sound stage is not just front and center but wide, high, deep and solid and even at low volume late at night the impact is still there. It's worth a try but it will not be to everyone's liking.

@@lorindamikaela Your comments on this topic are really interesting, and it’s something I am going to explore when I can find the time. It sounds like your setup has the LF “horsepower” to really energize your space, without strain or compression. To me that is one of the most important aspects of good bass performance, it should not be noticeable except when the source demands it, and it should be effortless.

Thanks for sharing your experience! Yes, bass is very tricky…and in another room raising the sub might give you better bass. That’s why it’s so important to try things out when you’re first setting up a new system or component.

Let me know as well I am going to cancel a tv console unit that i just ordered as it's dimenions are not same as subwoofer. Is it like a compulsion to place it on floor?

That’s very interesting, thanks for sharing as it will likely help someone out!

That’s an excellent cheap tweak…thanks for sharing.

We actually did real-world testing on this, I had friends & family allow me into their homes where I added subs to their home theater systems and did measurements. It did make a difference, but not in the way you’re thinking, it’s not for more bass and loudness, it’s for smoother bass.

Ahhh, that makes sense. I totally missed that video by the way, and you did explain it well. I think my next home theater improvement is going to have to be a bigger room! ; )

@@sjbenes Thank you! Yes, a bigger/better room is a dream for many of us. 😊

It depends on how you want to look at it. Since we cannot separate the room from the loudspeaker, they must be looked at together as a unit. With that in mind the target should be the best room-response possible, and gain at low frequencies from the room can assist in extending the natural bass cut-off of a loudspeaker or subwoofer. It can also be detrimental, so we will always need to live with some level of imperfection.

For a down-firing subwoofer the design is probably anticipating the loading from floor placement and that’s where it should be located. With a front-facing woofer you can certainly try raising the sub to control room effects, but you will likely loose some bass because of the reduced boundary loading.

Don’t use a subwoofer! Bass travels, not much you can do about it unless you have 4ft thick walls….bass *will* get through, ..even if they were 4ft, some bass would still get through.

Bass is very tough to control, and even with thick concrete or cinderblock walls it can travel. Some decoupling from the floor will certainly help…there are isolation pads available specifically for subwoofers, but their impact can be hit or miss.

And insulate your windows with foam and insulate your walls with like carpets unless you got the thick concrete walls also have carpeted floors if not get something to like cover the floors with extra carpet or soundproof it with the egg crate stuff on on the walls and windows and also sometimes it helps if the neighbors aren't home haha unless they're really cool and don't give a dang

It could only be some sort of modified bandpass design.

@@AxiomHomeTheaters I thought I thought it was just rearranging the speakers with like boxes and different things to put around them to make them sound deeper and clear that's what I thought

@@AxiomHomeTheaters yeah I've been messing with speakers since I was about 13 14 and I'm 48 now sometimes you'll hear a song and you rearrange your speakers in a different way I even put them in the closet it's up in the air and whatever and keep it that way for a little while and then change it up again you know it's just like messing with the speaker wires and trying different things it's kind of addicting you know it's like a little hobby

@@damondteachout4948 Playing with positioning can often give you surprising results, and it's cool that you still enjoy trying new things with your system! Although I'm less "into" the hardware side of my system these days, I still do get intrigued by experimenting with my setup or a new piece of gear.

Agreed, love these no nonsense videos.

Thank you both for the kind comments!

😂

Bruh.. I'd love to see that 😂

Not sure what you are asking? Normal memory cards should not be impacted by magnetic fields.

I'm curious about why you went this route, i.e., what the problem with the original SW placement and how you determined that a platform was the solution. Thanks!

It’s a great idea for some setups.

The first thing would be to stick to a front-firing subwoofer, a sealed design rather than ported would be a good choice. Also, don’t go for a bigger subwoofer than your room requires. I would suggest that you check out the isolation pads and stands that are on the market specifically for subwoofers. They won’t eliminate the problem but can make it better.
