Highly respected and incredibly well reviewed. Each speaker has 2 of the crossovers you see pictured. Each also has two of the 7" illuminator drivers, a mid range driver, and a beryllium tweeter. I just showed one of each for reference. Check this out on the madisound site under 3 way kits. This is the best they sell and would represent a speaker comparable to that of one in the 15 to 20,000 range. Everything is brand new and never been hooked up. I also have a pair of custom made cabinets in Ribbon mahogany that I will give to the person that comes to pick this up. I will include shipping at my asking price for the parts only. Cabinets are for pick up only, I won't ship them. The cabinets are in perfect condition except for minor damage to back top corner of one speaker, the other one is perfect. Did I mention they are free? They look perfect from the front and every other angle. This speaker uses the state of the art illuminator drivers and the scanspeak beryllium tweeter. The tweeters alone are about a grand, and used in some of the best speakers in the world. If you build speakers, here is your chance to save about 500 on the kit, and get a beautiful pair of custom made cabinets for FREE! If you just want the kit, then I can ship anywhere in the US for free. I am having to move suddenly and have no time to build them anymore. My loss is your very huge gain!!! Regards.
