I have a 2 high performance REL subwooferss positioned behind my couch and for me the best compliment I get is when a friend mentioneds... "how come your little bookshelf speakers sound so huge" and that's when I think to myself.... oh yeah that's how it's done 😁
If you have speakers that HAVE to be crossed high, like 100-200 Hz, a good hack is to put the tv in the corner, with the sub behind the TV. I recommend to just get speakers that can all handle being crossed at 80Hz or lower, crossing at 80Hz or lower helps a lot to keep the sub hidden and blended. A lot of small speakers will claim to go down to 80Hz, but they will still struggle with bass and mid bass even when crossed at 80Hz, resulting in the speaker sounding wonky at high volumes. The bigger and clunkier the speaker, the less likely this is to be a problem, try to get something that can legit get down to 60Hz, including the center.
I have 4 subs. Two up front and to in the back. All four subs are about 4 to 5 feet from the walls. Subwoofer placement will change the low frequencies in the room. Case in point, with dual subs in the front next to the LCR. The low end base will be more present during gun shots, punches connecting, head on car crashes, Helicopter fly overs ect. If I move the front subs to the sides of the room, all that low end frequencies I just explained will be gone and your LCR will have to go at it alone. Having the 4 subs covers more than enough. However, if I add 2 more subs for the sides walls in the room It will be perfect.
If you have a wooden subfloor then you will have localisation from the subwoofer... Concrete floors make it harder to localise... Clamping the subwoofer to a wooden floor as appose to isolating will give you a early arrival time of low frequencies which can be fun... More than 1 option when using subs...
Great video. Great information. I’m gonna have to invest in my fourth subwoofer. Because it’s annoying. That my third sub can be located Because it’s on the side of my couch.
I felt an itch to give a recent (read more) example of what I talked about in my first comment. So I've been listening to my JBL Studio 220's for a month now. The 4" polyplas midbass comes from the N24II, witch was a decade ago when the studio 2 line came out. Now it's 2 decades. The little 4 inch can't handle loud playback crossed at 80Hz and don't even think of running it full range. This is the FOURTH JBL speaker I've owned to use this bass driver. N24II, E10, Studio 130, and then the Studio 220. Lazy engineering. The tweeter is new tech, but everything the bass driver does is old, outdated and sounds like crap to me. The cabinet bass tuning sounds bad, and the rear port is bad sounding through a large part of the frequency spectrum. I have it crossed at 120 Hz (with Infinity PS28 sub) because that's as High as my Denon AVR-683 will go. Even THEN, The bass gets fatigued easy and the midrange, midbass is never great. Add the fact that the tweeter is bright, and the bass driver will never keep up with how loud you need it to go when the speaker is far away like it needs to be, AND the problem of having to potentially run the crossover so high and having the sub stand out super bad. Not worth the 150 spacebucks sale price. Not even as a surround channel. Plan to sell after review is up on my channel. I would try the 230's because a 6" would solve a lot of the problems. Just because a speaker is smaller, does not mean it will produce higher frequency's better. A 6" could produce better midrange because it's not trying super hard all the time to make the bass happen. My JBL Northridge 28II's are a 2-way 8" crossed at 4000Hz, compared to the N24II being crossed at 3000Hz. The N28II's have some of the best midrange in a consumer level speaker I've ever heard, and you can cross them with a sub at like 60-70 Hz and have it give a legit performance at volume. The N28II's could potentially be much better with a crossover upgrade. I hear the cheapness in the signal path, now that I've tried (slightly) better things.
@@Echo-jg8is I believe it may help blend your main speakers better with your sub to ensure that you don't hear a gap between where your main speakers roll-off and your sub kicks in
Yes but it can be slowed depending the material it travels in or through. Just like anything else, an object in motion stays in motion until an outside force stops it. So the speed of sound outside your home will be faster than the speed of sound under water. There's not a set speed. But there's a maximum speed.
@@Kpaceguy Thanks for the reply, my friend. I think we may have lots of points of agreement. The speed of sound, as I understand it, is generally dependent on temperature, pressure, and the medium (eg water vs air). This would apply to both low and high frequencies alike if they are in the same environment, for instance, speakers and a listener in a room. While some part of the bass may travel through the structure and hence have a different speed because it is in a different medium, this will actually put it out of phase with what's that going through the air and be a kind of distortion. In any event, it would probably contribute little to the overall energy. I also understand that sound is a wave and not an object, particle, etc. Hence, the laws of motion don't apply in quite the same way. The peaks higher frequencies will encounter one's ear more often because there are more of them, that is waves going by at the same speed as the lower frequencies. The fewer peaks of low frequencies will encounter the ear less often because there are fewer of them going at the same speed. But the waves are all moving at the same speed. High frequency peaks pass by more quickly because the waves[lengths] are shorter than low frequencies, not because they are going slower. I believe the speed of sound in water is about 4.3 times the speed of sound in air. On a fun *note": The speed of sound in air at typical temperatures and pressures is usually given at 343 MPS. Apparently, the maximum possible speed of sound is reported as 36 KPS. This, however, is a theoretical estimate done with things like quantum mechanics of a relatively extreme state of matter that cannot be obtained with our present technology. Please let me know if I've missed something. I really enjoy your channel,
Subs produce 30 feet to 60 feet of LFE waves inside your room. This is why the volume on your subs has to be managed because all those waves will cause your ears to feel closed in. Sometimes popping sound in your inner ear along with eardrum pulsating like if you have tinnitus.
