Natural Cherry Klipsch Cornwall IV Floorstanding Speakers. Brand new, never used, only unboxed once and kept in original boxes since purchase. One big upside is the fact that you can drive them to extreme levels with very little power, so there is no need to invest in an expensive, high powered amplifier. NEW TRICKS - BETTER SOUND Its been said you cannot improve on perfection. Not true. Klipsch engineers have continued to carry on the groundbreaking vision of company founder Paul W. Klipschs unique approach to acoustic performance with upgrades to the Heritage Cornwall IV Floorstanding Speaker HEAR AND SEE THE DIFFERENCE WHATS NEW? Inside, the Cornwall IV features a new, mid-frequency driver and a new midrange Tractrix horn for improved better clarity and detail, as well as new ports for expanded clarity and deeper bass. The outside of the Cornwall IV is a change from its predecessors as well. It features a new logo design scripted to match other Heritage products, a new matte black riser to give a floating appearance, and an updated brushed metal premium input panel. BEST OF THE BEST As the largest of the compact” Heritage speakers, the Cornwall IV offers the highest performance of any non-fully horn-loaded speaker we make. Only the legendary Klipschorn and La Scala (with their horn-loaded, low-frequency designs) exceed the Cornwall in bass extension and output. BIG BROTHER Initially introduced in 1959, the Cornwall speaker was designed to serve as a larger, full-range alternative to the Heresy when used as a center channel speaker between two widely spaced Klipschorns. Thus the Cornwall is likely to be the worlds second commercially produced center channel speaker. HOME GROWN The little town of Hope, Arkansas is the birthplace of the Klipsch Cornwall speaker. Assembled with handmade cabinets since 1959, we are proud to continue to build and assemble these hand-crafted speakers in Hope.
