Some of you have heard these either at my house or at CAF. I've changed some of the capacitors in the crossover since CAF, but otherwise they are unchanged since then. Why would you be crazy to buy these? Well, the main reason is there's no resale market if you ever decide you want to sell them. After all, who ever heard of DR Audio Works? The thing is, if you come over and listen to them you may feel you'd be crazy not to buy them. That will of course vary from person to person, but every one who has heard these here lately has heaped praise upon them. I don't charge for an audition, in fact any excuse to spend the afternoon listening to music is a good excuse as far as I'm concerned so feel free to come over and kick the tires.
The pair I'm offering for sale here is the first pair I made. The bass cabinets are the same as the final version. The top cabinets have some minor changes, but I do not believe I could pick out which I was listening to in a blind comparison. The best part is the price, this pair is $6,500 including speaker cables. You will need to add amplifiers - separate amp(s) for the bass cabinets, and a crossover to separate the signals for the bass cabinet and top cabinet. There are lots of options for both amplifiers and crossover, but if you went with the setup I used at CAF it would run you another $2,200. I'll be happy to discuss all the options when you come over for a listen.
I've included a couple pictures of the rear of the bass cabinet. The bass driver is dual voice coil. I believe most people connect the voice coils in series on these drivers but I have provided the option to drive them in parallel. Each voice coil is four Ohms so in series it's an eight Ohm cabinet. With the voice coils in parallel you need two channels to drive 4 Ohms each. This is how I use them. You get more control of the driver (higher damping factor), and can dump more power into them without super high power amplifiers. The amps I'm using for the bass cabinets are Crown XLS1502's which are rated at 525 Watts per channel into 4 Ohms or 1,050 Watts per cabinet. The amplifiers retail for $499 a piece.
The top cabinet uses an external crossover to keep the crossover components away from the vibrations inside the cabinet. I've provided separate connections for the mid-bass drivers and the tweeter in case you want to tri-amp the system. I did this for a while when I was figuring things out but use the external passive crossover now.
As it happens, I have a complete duplicate system of what I'm using right now including DAC, main amplifier and cables so depending on how blown away you are you could walk away with the exact same system. To be clear - these are the only pair of these that will be available and anywhere near this price.
