Cables "ARLA6" www.americanradiohistory.com Quality is a word often loosely used. "High Fidelity" is a term also often exploited by manufacturers of every type of sound reproducing equipment taking advantage of the present public interest. In most cases this equipment produces neither quality nor faithfulness of performance justify- ing use of the term. High fidelity sound reproduction has long been a specialized science and art practiced by too few manufacturers having a history of leadership, progress and intrinsic sense of dollar value. You may judge the validity of present claims to the classifi- cation "High Fidelity" by determining whether the manufacturer has a history of sound practice and integrity in the art. Such developments as the Jensen Model 530 Coaxial loudspeaker typify these histories. At one hundred and twenty -nine dollars and fifty cents this finest of 15 -inch coaxial speakers is acclaimed as a milestone in speaker engineering. Cost has not been a factor, though experience in design and production facil- ity have kept the price within reach of all. The low frequency unit is newly designed for smooth transition in the crossover region. The crossover network is included as a separate more efficient unit. The new compression driver has been developed as a per- fect match for the high frequency divided cellular Hypex horn. Wide range extension, unusual smoothness and outstanding balance of response guarantee an impressive professional realism unique in two way systems. This new Jensen 530 adds to the many reasons why in loud- speakers Jensen has been the world's quality standard for more than a quarter century. Other fine Jensen Coaxial speakers are: Model H 520 15" speaker at sixty -nine dollars and fifty cents. Second only to the 530 in performance with combination driver high frequency unit loaded with multi- cellular Hypex formula horn -crossover network with controls is built -in feature; its extraordinary high power rating and efficiency are due to the advanced design Alnico 5 P M magnetic structure. Model H 222 12" version of the H 520 at fifty -four dollars and fifty cents is ideal when speaker and enclosure area is limited. Model K 310 15" Coaxial at thirty -seven dollars and sixty cents. Model K 210 12" Coaxial at twenty -four dollars and eighty -five cents.
