Well, here is the thing.
You can't get the same drivers as B&W uses... Plus, their drivers are engineered to work with their boxes and crossovers.
I have a busy life as most people do and I don't have the time nor the equipment to design proper crossovers to specifically match the drivers as they do. Nor can I afford to individually audition components and lots of drivers to find the ones that match what I am trying to do.
Just curious have you ever seen the inside of a B&W loudspeaker? It's not just a box. There is a lot of deadening which is strategically placed. Also, I seriously doubt that I could build a Nautilus taper tube in the same fashion in which they do. Also, the matrix and bracing system used is very superior.
There are a lot of speaker manufactures that half-*** their drivers, boxes, crossovers. I honestly believe that with time and money I could design a loudspeaker much better than many of them. However, in my personal opinion and from my experience with B&W they are very much not like other companies. Their speakers are built with more care, expertise, and engineering that I have time and skill to give.
If, for a second, I could get all the drivers. I could build the crossovers. I could design and build the boxes, and finish them with the same look and feel as B&W. I would still be out money. Here is why, my time is valuable. When I am not listening to my speakers or on here reading posts (which is my comedy for the day usually) I am studying or working. Not doing these things would cost me more in the long run than purchasing the loudspeakers from B&W. By the time I put all of the time, effort, and money into equipment and supplies I would probably be out 2-3x of what the speaker actually cost me. Plus, you have to figure that you are not just paying them for the drivers, cabinet, crossover, and every other piece of hardware. You are paying them to do the service of designing, building, and testing the speakers for me.
And, in all honestly and seriousness I love the B&W sound. It is what I enjoy and what I like to hear in my loudspeakers (which is why I bought them). So, why would I want to design something to sound the same when I already have what I want... //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
