Thanks for noticing some of the recent changes to our website. We continue to plug away at it and will continue to do so as needed. In the past, we have taken a more passive approach to the web, but I intend on being "online" more by updating our website more frequently and participating in this forum as an official Aerial Acoustics voice.
On that note, a comparison between our Model 7B and forthcoming Model 7C seems warranted, so without further ado:
Both Models utilize a 1" titanium dome tweeter.
The Model 7C will utilize a 6" midrange versus the 5" midrange used in the Model 7B. The Model 7C midrange will be very similar to the one used in our Model 9.
Both Models utilize a dual 7.1" woofer bass system. These provide the cone surface area of a single 10" woofer, but allow for a significantly narrower baffle. This is done to improve the "look" of the speaker (think tower versus a pyramid) without sacrficing low frequency reproduction and has the added benefit of providing better imaging due to the narrower cabinet.
Both the tweeter and woofer are newer designs and have minor improvements when compared to the ones utilized in the Model 7B.
Both Models are rear-ported and share similar dimensions. The Model 7C will have a cabinet with curved sides which gives it a more contemporary look when compared to the Model 7B, which is essentially a rectangular tower. This is the most visable difference and most people that have seen the prototype of the new design have been extremely impressed. The Model 7C will be deeper to pick up the cabinet volume that is lost by curving the sides. The volume of the cabinet is an essential element to the low frequency reproduction in any speaker design and we didn't want to lose any with the new model.
Cabinet finishes will likely be; Rosewood, Natural Cherry and Black Ash. We may also offer High-Gloss Cherry and Titanium.
The Model 7C is predicted to have a suggested retail price of $7,500 US per pair, compared to $5,500 US per pair for the Model 7B. We are hoping to be shipping the Model 7C this summer, but we follow a "design to achieve the sonic goals, not a date" philosophy. So please don't hold us to price and timing quotes as both are subject to change without notice. They are best estimates based on where we stand today.
So you could view the Model 7C simply as the product that fits between the Model 7B and Model 9 in terms of features, performance and price. Perhaps we should have called it the Model 8, but since we already used that name in the past it would have been too confusing. Also, the overall system design more closely resembles that of the Model 7B. So Model 7C it is!
Hope this helps.
