Apologies if this has already been answered - or if things chance before I get this posted

I have been browsing the web site, and I notice that, at least at the time of posting, there are some differences between the English US & Canadian site. For example, there are more HT options on the US site, and that some of listed specs for certain speakers include frequency response curves that don't appear on the Canadian site.

Are these HT offerings only available to US customers or is this simply a case of the web site updates being "in progress" (I totally understand that, managing a web site myself!)

One further question regarding the curves: are these anechoic measurements for on-axis response?

Thanks for any info!

Bill
