[QUOTE="Robert Burns, post: 22917, member: 76"] Re: 12v Eco project sound system Dan: I built only 2 BF designs and while I've read everything BF has written about his designs since way before he started selling plans, I haven't heard the designs you mentioned. That's why I value the object feedback I've gotten from guys ( like Jeff and Ron ) on their experience with BF designs. One of the most powerful biases that confront a DIYer is expectation bias or what I call builder's bias: Basically the builder is convinced the end result sounds good because it has to - the builder simply puts so much time/energy to admit defeat, or caves into opinion of others. A forum ( ancillary to a business ) probably cannot expected to be completely objective, if BF can make money to some selling plans ( some of which haven't changed in 50 years ) that's fine. In the past decade with the advent of computer based modeling and testing there are a lot of options. A major reason that sound systems demands are identified and quantified is to logically determine what is needed/will work. That does require valid predicable performance from a speaker design.
