[Special Audiocircle offer below]The Story...
Back in 2007, Dennis Murphy approached us about a speaker that he, along with Paul Kittinger, had designed and encouraged us to bring it to market. That speaker became known as the SongTower.
Over the years, the SongTower has proven to be the most popular speaker we have produced. It has earned numerous awards, including an Editor’s Choice Award from The Absolute Sound for seven years running.
This past year, we asked ourselves a question: "How would this design change if we took on a similar project today?" There was only one way to find out.The Search was On
Naturally, the first step in any new design is the selection of drivers. Speaker driver technology continued to evolve since the original SongTower was born and we wanted to take advantage of industry advances. For example, we have seen the widespread adoption of ribbon tweeters over the years and, more recently, ATM tweeters.
The original Heil Air Motion Transformer (AMT) has been around for decades. We have used it in a number of custom, one-off designs over the years. But recent developments have drastically lowered the cost and size of this type of tweeter.
Our research unearthed an OEM ATM tweeter at a cost that made this an ideal driver for this project. This new tweeter offered improved detail and transparency in the high treble.
Once we settled on the tweeter, it was time to look at recent woofer developments. Over the past few years, driver manufacturers have introduced new woofer designs with many different types of cone material. Among them are ceramic cones.Why Ceramic?
According to engineers at SB Acoustics, "Ceramic cones offer smoothness and harmonic richness unavailable from conventional paper cone material. Ceramic materials also offer significantly higher stiffness numbers and slightly better internal losses than typical metals such as titanium or aluminum."
The ceramic woofers we selected increase both midrange detail and bass extension.
Now that we had the drive complement nailed down, it was time to address the cabinet.The Cabinet
In keeping with the original SongTower design, the SongTower II design utilizes a mass-loaded quarter-wave transmission line cabinet. Paul Kittinger did his usual excellent job designing a perfect cabinet for this new design.
With the drivers and cabinet design complete, it was time for Dennis Murphy to develop an appropriate crossover. And, as usual, Dennis did a stellar job.Introducing the SongTower IISpecial Audiocircle Member Offer
When we set out to produce prototypes of the new SongTower II design, we ordered enough parts to produce 10 pairs of speakers. Why? Because until you actually finish a test pair of speakers, there is no guarantee that the design will work out. And we didn't want to have excess inventory sitting around if the design failed to work out. Now that the design has proven itself, we want to give it a good send-off.
So here's the deal... We are offering these first 10 pairs for the price of the original SongTower - $2395. Once they are gone, the pricing on our SongTower II web page
, $2695, will be in effect.
