Acoustics rules are not a tenet, but a method to avoid of rough mistakes. This room doesn't seems to me simple. However, we have to remember some of them. The first of all, good bass responce requires dense and massive fences. For this room we see to many windows, which hinder in following it...

Your statement is in clear contradiction with the theory of multivariant analisys. And my practic too.

Sorry, but I don't understand, what do you mean under "sweet spot"? If we're talking about a number of such a LF source positions, where the FR to be smooth and without big deviations as a result of task solving with multyple parameters, then it means, that for these parameters, including room...

There are two opposite points of view in this question. The first - it is possible to repair any problem in LF range by means of adding LF sources. No doubts, it's true, but you have to use too many LF sources sometimes. Trinnov audio is the first, who can use such a method successfully. The...

I still think, that for the best sound you can get from your room and subwoofers set, you need to understand, that room and set have to be in "Harmony" together. AND for this goal only one, or maximum two subs is enough. It means, that your sub or any other low frequencies source can be...

I've got something may change your mind. I know nobody, who did research about all important parameters, which are capable to influence strongly at initial FR for rectangular rooms and even more so for arbitrary geometry. Although FEM-algorithms are quiet ready to solve it for arbitrary room...

Hello! I'm a new in this theme, but for REW use experience. This is the invitation to discuss for some improving (to my opinion) REW in low frequencies problem solving. Sorry in advance, if it will be not new for you. Briefly, if to define the space of variables, which are responsible for...

Hi! My answer - I try to avoid of a sub use at all. To be honest, it's not simple task for Home Theater, but stereo, especially if your speaker's pair has LF range from 25-30 Hz. Due to dependence between Acoustical Room Dimensions and LF Power Point for equilateral triangle: sources-the test...

Such a use of thick absorbing material is not a general-purpose method for to solve LF issues at all. The first of all, ANY shaped rooms anycase have modal frequencies. The second, thick absorbing materials strongly reduce sound decay for mid and high ranges, therefore you have a risk of big...

And one more. Nyal Mellor and Jeff Hedback's advice for (2x) of 5/8" gypsum board like your room lightweight wall construction for low frequencies response causes confusion to me. The first, because it doesn't have sufficient mass (about 20-25 kg/m2 - too little mass surface. The surface mass...

Let me say some words about "good room acoustics". Nyal Mellor and Jeff Hedback's article introduces controversial provisions have to be proved. For instance, the sound quality for low frequencies must be based on, the first, an ear SPL sensibility. Well-known value for it is in the range 1.5 -...

To apply this device one needs its characteristics. First of all - absorption capacity by frequency. The main disadvantage of such a devices - low efficiency and wide band range, if you try to apply this to low frequencies issues. One more inconvenience - you will have to find the best place for...

Join in Sonnie Parker wishes. Have a good news and future health!

The first step for any installation is to get as smooth as possible FR in low range. With accordance to you speakers this role belongs to subs only. The main difficulty is that subs placement may correlate with main speakers position and if subs will placed far from their places and generate...

It's necessary to add, that excessive amount of bass trap use is not good way for acoustical treatment at all. If you take away any mode from your FR by this device, it means, that you take away all subsequent modal frequencies too. Hence, you impoverish your FR, make sound dim and poor. For...
