Pioneer Elite SP-EFS73 Floorstanding Speakers

Does anyone know how many people have to request these speakers for them to offer these again? Is there a way to promote a product here so people know it can be requested? Sorry, I'm new here. Also, Fry's had these on clearance recently for $169.00 each. Sadly I missed that price. Does Massdrop have the buying power to get pricing like that? I have to believe they'd sell a ton of these if they could also hit the under $400/pair mark. Fry's was sold out of these quickly :(

They use two different (but still accurate) words to describe the same driver. Apex is the top or highest point of something... in this case a speaker cone, the tip or center of that cone is the apex. There are many schools of thought on how to achieve a single point source for the mid and treble drivers. I have an offset D'Apollito array in my tower speakers, KEF, ELAC, Pioneer and others use concentric drivers, yet another is using a full range driver like those employed by Tannoy. You are accurate that designing a proper concentric driver is difficult, this particular speaker was designed during Andrew Jones tenure at Pioneer. If there is a designer I would trust to understand the pitfalls and benefits of this type of driver, he would most certainly be one of them.

My strong suspicion is the upward facing and front facing driver components are identical units, yet the writer describes each unit separately AND differently. In fact, I'm going to make the rather strong claim that a single unit cannot be created which has the tweeter integrated (flush) at the APEX of a 4" driver, as stated. Doing so would put the tweeter smack in the middle of the surround, also interfering with 'balance' of the larger driver. Yamaha, and I'm sure others, have designed the larger driver with a 'bite' in the mount to reduce distance between centers, but the tweeter is still outside the radius of the bigger driver.
