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...

No doubts, your ears sense is the Chief Justice anycase in accordance with your personal taste. In general, room acoustic treatment seems to mushroom picking in deep forest: you are looking for any mushroom, take it, and after some these acts you wonder to surprising changes. For mid and high...

There are two methods: to hear and to see. What is difference between them? The thing is that some of changes are difficult to sense briefly. Sometimes you need to have either very sensitive ears or big experience, because aged people have worse hearing, then young. That's why to use...

The first of all, you need to get noise response of your room, because there is suspecting, that power supply (or something else) in your room may causes distortion at this frequency. If not, then you need to choose the best position for stereo only, especially, if they work good in LF range...

My favorite movies are Cast Away, The next three days and of course, I like Back to the Future very much, especially N3.
