Loudspeaker kits were very popular. This Speakerlab kit was typical. Notice the tweeter is a SEAS soft dome tweeter, which was common in kit speakers of the late 1970s and early 1980s. Groovy hair too!
Speakerlab, from the mid seventies through the mid eighties, put out a great line of component speakers that would fit most anyone's appreciation and budget to facilitate "all" listening tastes. The SPEAKERLAB K-HORN was no exception. At 10 watts up to 200 watts of musical input, these speakers deliver a clean, well pronounced and comforting listening result. Design specs have been debated for years as to "who" created this design (Speakerlab or Klipsch). Either way, the Speakerlab's version has always delivered a most remarkable listening experience to whomever has been fortunate enough to had the opportunity to do so. With any classification of music, the Speakerlab K-Horn will actually bring you into the music you are listening to. Whether you are using a tube amplifier/receiver or a solid state amplifier/receiver, the results of these speakers will astonish most enthusiasts and even the most particular of listeners.
A typical 1970s kit speaker, in this case an assembled SpeakerLab kit. Note the vertical midrange horn. This isn't a mistake. It's an ElectroVoice 8HD, a diffraction horn that is meant to be mounted vertically. Also note the E-V T35 horn tweeter and the twin 8-inch woofers in a bass-reflex cabinet (described as a "tuned port" back then). Great sound on a budget! Don't criticize the sloppy silicon caulk seal around the tweeter, it was customary and could be seen even in commercial designs…
The Speakerlab 7s were made right here in Seattle, and feature a large and highly efficient 12″ woofer, 10″ passive radiator, and use Electro-Voice drivers for the mid-range and treble horns. The vertical midrange horn will produce a fairly narrow sound field, but otherwise, these are known as thumping hard and delivering exceptional clarity. Truly a fantastic rock speaker from the classic hi-fi era.
