I have the exactl same inquiries about this product as well. I also recently purchased 3 of these MSL-7700R speaker systems, although I do believe they are a scam. I picked up 3 of them off the streets in Downers Grove, IL, a western suburb of Chicago, where a guy claiming to work for a sound company out of Joliet, IL came up to me while I was driving and said he had 3 extra of these systems that came in on an order where the distributor accidentally gave them more than they asked for. This scam artist in my mind, who was accompanied by another guy and girl, then proceeded to tell me that his boss let him take them and do whatever he wanted, so he was just trying to get a little cash for them on the side. He showed me the MSRP price on the side of the box and told me that their sound company sold them for 2000 a piece. Being naive and a lot bit stupid, I ended up giving in to the guy without finding out any information on the product and forgetting to get his name and company; no contact information at all. In the end I spent about 1500 dollars cash for all three thinking I got a good deal. But then after I got home, I proceeded to search for Millenium Sound Lab products and to no avail found no such information except for a few Ebay entries and your forum. I did find a website, milleniumsoundlabs.com or something to the like that also seemed to be some type of hack site. I have no idea where they are made, no idea how much they are worth, and no idea if I got ripped off or not. They do work and to me sound pretty good although I've not much to compare it to. The only address I could find anywhere in the literature was on the generic warranty form which had an Elmwood Park, IL mailing address for warranty input which is not too far from Downers Grove. It would make sense that these were sold to me in Chicago if in fact the hack speakers were made in the Chicagoland area as well.
Regarding your speakers, where did you get them from and how did you hear that MSL brand was supposed to be top of the line if you can't find any literature on them either?
I'll probably end up keeping all three because I can hook one up to my computer through the AUX RCA jacks and maybe someday use another to a large TV when I can afford one. I'll probably give the other one to my siblings.
If you find any more info on this interesting product, write back please.
I bought a MSL-7700R home theater 5.1 system. My question is, has anyone ever heard of this system? I can't find anything online about this product. I have learned that they produce top of the line products, but I can't find their complete systems. Please get back to me. Thanks.
