Instead of rules of thumb, I suggest placing subs where they measure best. Complex interactions from various wall, ceiling, and floor boundary structure and surfaces are endless. So you've just got to experiment and measure... without ruling out any locations, corners included. I realize everyone wants quick rules of thumb of approaches to try, and those to never try. I agree, corner placement of speakers/subs are often problematic. However, there's instances whereby corner placement is ideal for acoustic performance.

I have my system based out of a corner, where the full range speakers are off the wall and separated, but a 12” subwoofer facing into the corner. Amazing bass! I’m really surprised just how much more sound the sub has facing into that corner, as I tried the configuration many ways. This is great on a budget system, if you just have a single 100 watt subwoofer.

@@AcousticFields Room modes are not created by too much energy. They are resonances caused by coinciding wavelength and room dimensions. Take away the resonance and the excess energy goes away.

There’s no more total sound energy, it’s just distributed more evenly around the room between the subwoofers.

What causes low frequency issues within small rooms? It is the dimensions of the room. Certain energy will fit within the given dimensions and certain, usually lower frequencies, will not. The room modal issues are produced by excess energy that doesn't fit within the room to begin with. How can adding more energy into a problem that is produced by too much energy to begin with? It can to a point but the quality in sound is not there. It is quantity, not quality. A good sub today is at least 2.5K. With 4 you are at 10 K. It is best to treat the room with the 10 K and have just one sub. A single sub produces more energy than your room can ever handle. You are just not hearing that single sub correctly because the room will not let you. If you take the room out of the equation with proper treatment, you hear more with less energy.

It sounds as smooth as a baby's butt as long as I'm not in one of the null zones.

It is nonsense to treat corners and call it a solution to the problem. Since the defintion of an axial mode is unwanted lower frequency pressure between two parallel walls not two parallel corners.

You must develop a strategy and apply the appropriate tactics. Corner treatments are a tactic without a strategy.

You must use the required amount of surface area coverage on each wall. It is the complete wall surface area that is causing your issues. For this frequency and amplitude issue, you will need our Carbon Panel. www.acousticfields.com/product/carbon-panel/ Most wall surfaces in small rooms take 4-5 units to treat. You must also treat the partner in crime which is the opposite wall. Remember that room pressure build up is produced at a minimum by two walls not two parallel corners.

If all the room modes end up in the corners, isn’t it advantageous to place bass traps there? In your corner bass trap video you indicate that they aren’t very effective because you’re only treating a small percentage of the total room surface area. That is correct, but based on what you say in both of the corner-loaded subs videos, it seems the corners are the *most important* area to place low frequency absorption.

This type of thinking Placing low frequency sources in corners produces 3-6 dB in room gain which is distortion that produces a muddy sound with no definition or seperation in certain octave bands. The room gain produces more energy but that energy is a combination of room sound and sub sound. To achive a tight clean low frequency in your room keep all subs away from walls. To increase resolution, treat the room properly with the proper low frequency treatment.

This is not a good start point for this process. Elevate the sub off the floor and place it on casters so it can be easility moved. Place in room center. Move in one foot increments in one direction at a time. Repeat process for another direction. Spend time listening to your music sources between sub moves. Sometimes you will know immediately, sometimes it will take a few songs. To avoid all of this, treat your room so it is pressure balanced. With a pressure balanced room, the sub will sound good anywhere within the room.

Hey I'm curious to know, are you against tactile bass ?? Because some scenes like gunshots, bomb blasts, dinosaur foot steps etc gives great movie experience when there is a good tactile responce that you can feel through the couch. And also chest kick in some movies. If you are not adding more energy to the room, we can't get tactile feel. What's your opinion on this ??

I am against gimmicks that pretend to take the place of a well treated and designed room. Low frequency energy is felt not heard. If these devices produce the tactile experience you desire than mission accomplished. However, once your room is treated to resolve low frequency energy down to . .5 dB, the tactile experience is already there is the oscillating waveform that moves through your room. I gurantee you that feeling of the wave moving through the room is greater than any vibration generating device. There is no free ride when it comes to acoustics.

@@AcousticFields first of all thanks for the reply 😊...I really appreciate you are a strong supporter of QUALITY not QUANTITY. 👍👍 Currently I'm using two 18" diy subs in a medium sized hall. For placement and alignment, I did whatever i can using REW. To get tactile feel, I had to increase the SPL, and it becomes painful on ears. Then I placed one sub "very near field" just few inches behind the couch. Now i get tonns of tactile feel even at low SPL. For movies it's awesome. For music, in terms of transient responce, it's neither very bad nor very great. It's just ok. I have to build bass traps targetting some specific room modes yet. Anyway ..all your videos are very enjoyable 😊😊😊👍👍 keep up the great work !!!!

Corner speaker placement increases room distortions. Try moving them out of the corners and listen to the increased resolution.

@AcousticFields
@AcousticFields 3 года назад
You do not need more pressure. Excess pressure is the reason you are not hearing everything and thus want more energy. You can not use more energy to treat a problem that is caused by too much energy in the first place. You need to reduce the existing pressure within your room through proper treatment in order to hear more.

I have nowhere near the knowledge of Dennis, but I think you would run into serious phase issues unless you have a massive room. Also to be small enough to add multiple subs and not "overfill" your room, those drivers would probably get too small to accurately produce real sub frequencies anyway.

So why did Electro Voice, Klipsch and JBL, etc. design speakers specifically for corner placement?. The EV Regency III and Klipschorn actually use the walls of a corner as part of the folded horn design. They do need a large room to sound good. I used to have an EV Regency III with an EV 18" in it. I just bought a JBL Control SB-2 subwoofer which has a 10" dual voice coil driver and is a slot loaded, vented bandpass design. It is triangular and made to gain full efficiency in a corner either on the floor or ceiling. The efficiency is less when placed in other locations. They came with mounts for corner placement between floor and ceiling or on a wall for commercial applications. So far I have it away from a wall or corner and is still fairly efficient. I have yet to try different placements. I have either stone or concrete walls and floor with an acoustic tile ceiling, and a unique room, so a different situation than most.

Stacking of subs is a great con. Firstly, in the concert industry there is no line array subs. It’s never done. Secondly, you get 6 subs stacked up in 2 columns and then use them in low volume for ‘better bass’. Ratio of 6 subs to 2 stand mount speakers. 🤣😂🤣😂

If you’re a broke person like me the best option is just to place your speakers where it sounds the best the most natural do you want your speakers not to sound like speakers do you want your speakers to sound like the room if you’re subwoofer sounds their best in the corners if that’s where they sound the most natural that’s where they go if your main speakers sound their best up against the wall that’s why you place them if your speakers sound the best when you pull them out into the room that’s where you placed in your room dictates where your speakers go not everybody’s got Tens of thousands of dollars to do what is the golden standard sometimes you just Gotta do what you Gotta do

Placing your speakers in the corners of your room will not produce a natural sound. It will be a sound that is composed of room gain which is distortion. There is nothing "natural" about room distortion. The goal is less room distortion.
