audioengr and sean, i called b@w regarding bi-wire application of my nautilus 801 speakers, they said the speakers were designed with bi-wire in mind and while they work fine with the jumpers, the eng.at b@w find they sound best bi-wired. sounds like what sean said. since b@w could care less about how you wire the product since they don't sell wire, i think i got the straight scoop on the bi-wire issue as it relates to nautilus speakers. i replaced long [20ft] runs of dunlavy bi-wire with much shorter runs oval 8 bi-wire and the soud is great. i think that some of us spend too much time trying to outthink the designers and when you think about that and the business ramifications, it takes some mighty ego's to challenge the guy who designed the product. i know i know the argument that all products are designed to a price point but in the case of bi- wire vs single wire plus jumper this makes no sense. as usual sean your analysis is right on point. it's interesting to note that the analysis plus eng. dept agreed with b@w eng dept on this issue. so i guess the issue is ,are your speakers really designed with bi-wire in mind or as audioengr infers as marketing hype. call befor you buy!
