I run a business. If i give everyone all my information for free, what use would I be over time and what would I gain from my hard work? The information I have, and use, is not something taught from a google search bar. I am a college and military educated acoustical engineer. Do you expect me to work for free all the time? Im not on here to joke around, I am on here to help people, but my time and effort is worth a price as it should be. Everyone should be glad it is so inexpensive. For the work I do, I can charge much more based on average labor and material costs and markup values for a profitable business. I do not use generic calculators. I do not use anything from anyone but what I have came up with and what physics allow me to utilize, along with specific formulas that have been proven effective in audio reproduction that cannot be altered in its purpose. I wrote two programs for my calculations and use them for deciding enclosure specifications ALL based on pre-handwritten calculations. It's not as simple as, "make it 4 cubes and tune it to 33 hz and put a lot of power to it and you will be fine". I am not that type of designer, or I would not be accurate. If you are looking for free and simple, then we have nothing else to discuss, I'm sorry. I have given out free designs before, but that is my option and right to do that at will. And it is not without gaining recorded information for improving my calculations either, if need be....or testing them out if they are new. By doing free designs every now and then, I improve efficiency as I am testing at the time I offer them, and it helps others later in the future and my business with speed and accuracy. Nothing i do is technically free, nor should it be. I'm sorry if you assumed I was anything else but a business on here. I am compassionate, but still professional. So, if you want my help further, yes, "I can't reply w/o a deposit to my paypal". I was send here from a good friend to help you and I have as much as I can with information unless you ahve more questions, but for getting specifications from me any further will come as a purchase of my time and skills.
