The Slims Tower
Since the introduction of the Philharmonic 3 loudspeaker, we have been exploring ways to provide a smaller and more affordable alternative tower that could provide virtually the same level of performance. This alternative is now a reality due to the recent availability of a less costly OEM RAAL ribbon tweeter, and the choice of a small Seas aluminum woofer that is capable of amazing bass performance when mated to a correctly optimized transmission line cabinet. Bass response is flat to almost 35 Hz, with an F3 of 33 Hz.
The titanium midrange driver is, like its counterpart in the Phil 3, capable of operating full range as both a mid woofer and a tweeter. We limit its operation to the most linear portion of its response, which varies by no more than +/- 1 dB. Also in common with the Philharmonic 3, the Slims features an open-back midrange chamber to add depth and realism to any recording that contains natural ambiance.
Despite its lower cost, the new RAAL ribbon tweeter performs as superbly as other RAAL models when used within its intended frequency range. Of particular note is the virtually perfect horizontal dispersion. This wide radiation pattern, together with the rear wave information from the open-back midrange, are responsible for the unusually spacious sound and deep sound stage of the Slims tower.
The smaller cabinet size and savings in driver cost allow us to offer the new Slims tower at a price of only $2,200/pr with a standard veneer and finish. We are not aware of any other tower speaker near this price that provides as high a level of driver and crossover refinement or bass extension. The cabinets are built by Jim Salk of Salk Sound and feature magnetic grills front and back, and a black satin plinth. Front baffles can be finished in either black satin or veneer. A perfectly smooth furniture-grade finish is available for an additional $300. The Slims tower pictured has the premium finish and a standard curly walnut veneer. Buyers can also choose from a wide selection of premium veneers for the additional cost of the veneer.
