The WF-34 ($1199 per pair, MSRP) features a one-inch titanium diaphragm compression tweeter mated to a 4.5-inch 80 degree by 80 degree XT Tractrix horn, crossed over at 2.7kHz to three 4.5-inch triple-woven fiberglass cone woofers with ceramic motor structures, all encased within a dual-ported bass-reflex enclosure composed of an exotic, non-endangered Berlinia veneer from West Africa, finished in gorgeous Espresso or Cabernet finishes. The XT Tractrix technology alters the surface geometry of the horn with four flower-shaped "bumps" to create a wider dispersion pattern than that usually provided by horns. The design employs two oval-shaped ports on the rear, fitted beautifully into the cabinet with sloped plastic fittings. Ditto for the dual pair of 5-way gold-plated binding posts.
Klipsch says that Berlinia is a sister veneer to Zebrawood and is often featured on luxury goods. Whatever it is, it looks downright fantastic, and certainly gives the WF-34 a luxury goods feel. Even the grill has a slick touch of its own, attaching via magnets with no visible fasteners on the baffle. Measuring 40 inches high by 6.5 inches wide by 9.5 inches high and weighing 33 pounds, the WF-34 provides a beautifully slim footprint and has some nice heft to drag around. Overall, the fit and finish of the WF-34 easily rank with the very best in its class, and even with some in the classes above it.
The WF-34 presents a nominal 8 ohm load with a very high 95.5dB efficiency. The speaker sounded optimally even with average power sources, although it did sound just a hair better when paired with better quality amplifiers.
The WF-34s threw a very deep, wide soundstage with crisp imaging that stretched beyond the speakers. The sound exhibited less directivity than do traditional horn speakers, with a larger sweet spot. The top end had a noticeably less edgy quality than typical Klipsch designs, but still provided lots of detail. It stayed coherent with the lower frequencies, added a nice zing to the presentation , and only very rarely sounded too crisp overall. The highs blended wonderfully with the midrange frequencies, and carried over a lot of detail. The WF-34's midrange lacked the honkiness typically associated with horns, with an open, fast quality that brought a lot of inner detail to vocals and piano as well as good body and even some richness. The high-to-mid transition and overall spectrum really excelled and brought some impressive levels of transparency and speed considering the speaker's price.
Into the bass, the WF-34 maintained its excellent detail and speed, and played pretty low considering the "smaller" cabinet size (it's not really that small). The bass exhibited punch and good volume, and stayed very much in time with the higher frequencies, a critical issue given the top end's terrific performance. The ultimate lack of extension took a back seat to the ability of the bass to complement the sound perfectly and bring its own crisp, musical qualities to the presentation. The WF-34 sounded even better when moved closer to walls, as the loading made the bass a bit more substantial with a lot of material, especially large scale classical tracks. The WF-34 upheld the Klipsch tradition of playing effortlessly at higher volumes, even when powered by average receivers and amplifiers.
