Topping many audiophiles’ best rock-n-roll speaker lists because of its incredible output and clarity, the Klipsch Heresy is a compact, three- way design that uses horn-loaded compression drivers for midrange and treble reproduction, and a direct radiating 12-inch woofer for the low frequencies.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eA LITTLE HERESY IS GOOD FOR THE SOUL\u003cbr\u003eBecause of its size, the Heresy offers the greatest degree of placement flexibility in the Heritage series. First introduced in 1957, this three-way horn-loaded loudspeaker is still able to deliver the awe-inspiring Klipsch sound that our fans around the world know and love.\u003cbr\u003e\u003cbr\u003eDESIGNED AND MADE IN THE USA\u003cbr\u003eThe Klipsch Heresy IV speaker is a testament to the quality that Klipsch demands from each and every one of its audio products. Remember great sound? We do, too. The Klipsch Heresy enclosure is made in the USA, by proud craftsmen in Hope, Arkansas, just like Paul W. Klipsch (PWK) intended.\u003cbr\u003e\u003cbr\u003eSTANDOUT FEATURES\u003cbr\u003eCOMPACT, THREE-WAY LOUDSPEAKER\u003cbr\u003eThe Heresy was originally introduced in 1957 with a compact three-way design utilizing a 12” woofer and horn-loaded midrange and tweeter. In 2006, the Heresy III was upgraded with a more powerful woofer and a bi-wire network as well as midrange and tweeter compression drivers, and features a titanium diaphragm for smooth and accurate definition.\u003cbr\u003e\u003cbr\u003eDRIVERS\u003cbr\u003eThe Heresy IV incorporates an all new K-702 midrange compression driver, featuring a polyimide diaphragm for exceptional detail and dynamics. The K-702 midrange is mated to the K-704 Tractrix® horn, providing you with a wide coverage pattern and smooth response throughout the listening area.\u003cbr\u003eThe K-107-TI titanium diaphragm high frequency driver features an all new wide dispersion phase plug, providing exceptionally even high frequency dispersion throughout the listening area, making for a wider, more accurate sweet spot.\u003cbr\u003e\u003cbr\u003eNETWORK\u003cbr\u003eThe Heresy IV has been completely revoiced from its predecessor, utilizing premium componentry in an all new high-fidelity network — minimizing electrical degradation throughout the circuitry — for truer to life sound with best in class efficiency and power handling. The new network draws from the classic three-way steep slope design of the legendary Klipschorn, La Scala and Cornwall speakers.\u003cbr\u003e\u003cbr\u003eTRACTRIX® PORTS\u003cbr\u003eFor the first time in its long legacy, the Heresy now features a rear port – improving low frequency extension by almost 10Hz, for room filling bass. Utilizing Tractrix geometry, the all new Heresy IV ports allow for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.\u003cbr\u003e\u003cbr\u003eBI-AMP INPUT PANEL AND BINDING POSTS\u003cbr\u003eThe Heresy’s premium, aluminum input panel accommodates large, high-quality speaker cables. Strong, versatile and quality binding posts provide the capability for bi-wiring or bi-amping.\u003cbr\u003e\u003cbr\u003eHIGH EFFICIENCY\u003cbr\u003eNothing in the industry sounds as big or is as efficient as the Heresy, given its relatively compact size. This model offers the greatest degree of placement flexibility of the Heritage series. The bonus slant riser base can be removed for cabinet installations.\u003cbr\u003e\u003cbr\u003eMATCHED PAIRS\u003cbr\u003eEvery pair of Heritage series loudspeakers is grain-matched, using wood veneer panels that come from the same timber. Each cabinet is carefully matched so that each speaker in the pair is practically indistinguishable from the other. The speakers move seamlessly together through the factory, and each finished product is inspected and labeled with sequential serial numbers, ensuring that your Heritage series speakers leave the factory as a meticulously crafted set.\u003cbr\u003e\u003cbr\u003eBOOK-MATCHED WOOD VENEER\u003cbr\u003eKlipsch only uses book-matched wood veneers for the Heritage series. The veneer leaves are kept in order as they are delicately sliced from the timber and precisely arranged to provide a mirror image at the splice joint — like turning the pages of a book. This gives each speaker an aesthetically appealing and consistent appearance that is treasured more than any other cut of wood veneer.\u003cbr\u003e\u003cbr\u003eBUILT TO LAST\u003cbr\u003eWhile each and every component of the Heresy IV is built to last. Klipsch has always recognized the unique and critical role of a loudspeaker’s cabinet in the sound reproduction process. From the craftsmen in Hope, AR to the engineers in Indianapolis, IN, Klipsch has always put an extraordinary emphasis on cabinet design. The Heresy enclosure is assembled using only the highest-grade adhesives and fasteners. The riser base can be removed for cabinet installation or placement on optional stands.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBrand Background:\u003c\/b\u003e\u003cbr\u003eFor over 70 years, Klipsch has designed and engineered its products in-house with the most talented, skilled, and passionate people in the industry - starting with our founder, Paul W.

We are looking for damaged or deteriorating woofer surrounds, dented tweeter domes, and cone damage. We also inspect the speaker connection points for loose or broken connectors.\u003cbr\u003e\u003cbr\u003eAfter the initial visual inspection we connect the speakers to a reference amplifier with our preferred test tracks. With the speakers placed with proper distance we listen to each driver to make sure that they are producing the intended frequencies with no signs of distortion or rattle.\u003cbr\u003e\u003cbr\u003eDuring listening tests with test tracks we check for proper stereo imaging and bass response at various listening levels. If there are any audible signs of issues, the speakers are taken to the bench where we perform a frequency sweep to isolate the issue so that it can be resolved by component repair or replacement. \u003cbr\u003e\u003cbr\u003eOur subwoofer evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, cone damage, or rubbing voice coils. We also inspect the input connections for damage.\u003cbr\u003e\u003cbr\u003eAfter the initial visual inspection we connect the sub at our bench and perform a sine wave sweep from about 200 Hz down to around 10 Hz. During this sweep we are listening for excessive rattle or other signs of improper function.\u003cbr\u003e\u003cbr\u003eIf the sweep passes we then increase the input level to evaluate how the woofer performs at high output levels. If the woofer has built-in crossover adjustments or multiple connection options these features are tested at this time. \u003cbr\u003e\u003cbr\u003eWe complete the subwoofer evaluation by feeding the unit with an audio signal in conjunction with our house music system to see how it responds to low frequency content in real world conditions while paired with a full range system.\u003c\/p\u003e","brand":"Klipsch","offers":[{"title":"Default Title","offer_id":67835645395198,"sku":"108166","price":4459.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/klipsch-heresy-iv-speakers-american-walnut-pre-loved-pair-841.jpg?v=1792789989","url":"https:\/\/skyfiaudio.com\/en-au\/products\/klipsch-heresy-iv-speakers-american-walnut-pre-loved","provider":"SkyFi Audio","version":"1.0","type":"link"}
