    Its funny many of them have some parameters some have all, they are Chinese companies and it seems nearly all do not have xmax. When I ask them they just say, we usually don't provide xmax. But, without xmax I have absolutely no where my distortion is kicking in.

        If they can't/won't provide the data you need don't buy from them. Problem solved.

          Agreed. Pay a few bucks more (maybe?) and get a good driver instead of a pig in a poke.

            Agree I will just pay a few bucks more and get a decent driver, I was just been looking for that perfectly tonned and speced up driver for dirt cheap but it doesn't exist. Actually, the closest(non Chinese) seems to be the Dayton RSS315HO. Some Chinese ones look good, but no xmax, most I have come across are just random Ali express drivers.

            I bought some half decent stuff from China but I won't risk it without an xmax. Appreciate your responses. I just wasn't 100% on what happens below the Fb in a sealed box. I simulated it a winisd and its clear when xmax is over driven, although it doesnt look like it has anything to do with the fb given in the pop up box hence my confusion. It seems it has more to do with the power level than anything else but if that is what im looking at thanks.

              For the most part, Dayton = made in China.

                For the most part everything = made in Asia. If the driver isn't made, which is to say assembled, there the parts are probably made there. Manufacturers without complete specs are probably knocking off name brands that might be produced in the same Guangdong region. If you want to see how bad it gets go to wish dot com and look at the golf clubs sold there. They're not just knock-offs, they're downright counterfeits.

                  I checked it out, very interesting. But, on the other hand state of the art DAC's from Topping for around $100 tells me that some goods can be made with superb engineering in China. The only downside is that its more a matter of luck than anthing else when choosing, and you take the risk. With a speaker driver for around $60 ish extra to get something that is more robust in design its not worth it unless of course it has been tested by a 3rd party.

                    Many very good products come from China. But not all products that come from China are very good, or genuine. If you're buying an unbranded product you pretty much expect that it might not work as well as a branded product. But it's a horse of a different color when what is represented to be a branded product turns out to be fake. I wouldn't be surprised to find out that it was Confucius who first said 'If it seems too good to be true it probably is'.
