I'm an Internet Project Manager for a major software company, and I personally think they messed up the basics.
The design is open and clean, which is nice, but the navigation must be crystal clear, and it's not. They need to group items the way a visitor expects to see their speakers grouped. In this case, most people want to see their speaker line up in a heirarchical structure, and grouped all in one place. Don't place the individual speakers in more than one place in the navigation, makes it confusing, and it's annoying.. I mean, I just saw this speaker under one flyout, why do I need to see if under another? Don't bury it down three flyouts, the whole list should be accessible from that first level flyout. And what does "Design Series" mean? If you want to breakup the speaker offerings, break it up by something that makes some sense... I don't know if Design Series is better or not as good as ESL. How about soemthing that illicits a Good, Better, Best type of rating/structure? Pick a navigation that makes sense, and that usually means the simplest and most transparent one.
Don't use a confusing nav to describe how one speaker is an ESL, a monitor, and good as a surround. These types of details can be explained on the speaker landing page, keeping the nav simple. You can maybe have an Advanced Search, that allows you to search for "monitors" or ESL, or whatever type of speaker you're looking for...
How about a dropdown, with quicklinks to each speaker landing page? The individual speaker landing pages have large images, which is nice, but apart from the speaker photos not being excellent renditions of the real thing, that overall image is just too large, and it's hard to find the subnavigation that gives you the details on the speaker. Those speaker landing pages should have basic info along with a clean image of the speaker, without the user needing to click yet another time to see if they can find what they're looking for. Who cares about fancy home interiors? Maybe a few to illustrate how they can look great in a home interior, but not every single picture. Some of the gallery pictures I think would be better at the main speaker pages, and the environment pictures maybe get moved to the more buried gallery.
I like the idea of "home theatre solutions", possibly by price/level, also liked the earlier idea of reviews, i'd put them on the landing page for each speaker. I also think recommended accompanying equipment would be great, but no audio manufacturer ever does that, and it's really what we're all looking for, they as manufacturers should know of some magical combinations with their product, yet they dont give us that info.
