The flagship of the KLH Model Collection, the Model Seven was designed by chief engineer Kerry Geist and made its world premiere at AXPONA 2023. Inspired by the iconic KLH Model Five and the acoustic suspension principles co-developed by Henry Kloss and Edgar Villchur, it is the most powerful and ambitious speaker KLH has produced in the modern era. The Model Seven features a \u003cstrong\u003e13-inch high-displacement pulp-paper cone woofer\u003c\/strong\u003e, a dedicated \u003cstrong\u003e5-inch pulp-paper cone midrange driver\u003c\/strong\u003e in its own sealed sub-enclosure, and a \u003cstrong\u003e1-inch aluminum dome tweeter\u003c\/strong\u003e, with a frequency response of \u003cstrong\u003e38Hz to 20kHz ±3dB\u003c\/strong\u003e, an in-room sensitivity of 91dB, and a low-frequency extension reaching -10dB at 26Hz. Sold as matched left and right units, two speakers are required for a complete stereo pair.\u003c\/p\u003e\n\n\u003ch2\u003eAcoustic Suspension at Flagship Scale: The 13-Inch Sealed Woofer\u003c\/h2\u003e\n\u003cp\u003eThe KLH Model Seven marks a significant engineering milestone as the first acoustic suspension loudspeaker ever built around a 13-inch woofer. Where conventional floorstanding speakers of similar driver size typically use ported bass-reflex enclosures to maximize low-frequency output, the Model Seven maintains the sealed-box acoustic suspension architecture that defines the KLH Model Collection. The sealed enclosure uses the compression of the trapped air volume as a pneumatic restoring spring acting on the woofer's highly compliant suspension, delivering low-distortion, linear bass reproduction that remains controlled even at the highest excursion levels. The 13-inch cone is constructed from pulp paper with a half-roll rubber suspension and a 2-inch diameter flat-wire voice coil, housed in a non-resonant die-cast aluminum frame. This architecture extends usable bass to 38Hz at ±3dB and to -10dB at 26Hz without the abrupt 24dB per octave port-unloading cliff of a ported design, and the sealed cabinet makes the Model Seven considerably more forgiving of close-wall placement than ported floorstanders of comparable output capability.\u003c\/p\u003e\n\n\u003ch2\u003eThree-Way Driver Architecture and Isolated Midrange Enclosure\u003c\/h2\u003e\n\u003cp\u003eThe Model Seven's 5-inch midrange driver is housed in its own sealed internal sub-enclosure, acoustically isolating it from the woofer cavity and eliminating back-wave pressure interference that degrades midrange clarity in conventional three-way designs. The midrange covers the band from 300Hz to 3,500Hz via 3rd-order electro-acoustic crossover networks, reproducing the critical frequency range of the human voice, piano, guitar, and brass instruments with low coloration and high dynamic resolution. The 1-inch aluminum dome tweeter with soft rubber suspension and precision-machined aluminum faceplate handles all output above 3,500Hz. The thirteen-component crossover network uses premium iron-core inductors and Mylar capacitors, consistent with the proven network topology used in the KLH Model Five. A three-position Acoustic Balance Control on the rear panel offers 0dB, -1.5dB, and -3dB attenuation above 400Hz, enabling precise tonal matching to any listening environment.\u003c\/p\u003e\n\n\u003ch2\u003eCabinet Engineering and Mid-Century Modern Design\u003c\/h2\u003e\n\u003cp\u003eThe Model Seven cabinet represents a meaningful structural step forward from the Model Five. The front baffle is constructed from 1-inch MDF, thicker than the 3\/4-inch side panels, providing a more rigid acoustic foundation for the large woofer and reducing baffle-induced resonance at high excursion levels. The wide-baffle geometry focuses sound forward and reduces diffraction and lateral reflections from nearby room boundaries. Book-matched real wood veneers are applied across matched left and right cabinets, which are sold as a mirrored pair, ensuring visual symmetry in the listening room. The included matte black 3-degree slant riser base angles the driver array gently toward the seated listener, aligning the midrange and tweeter axes without requiring any stand upgrade. Five-way gold-plated binding posts on the rear panel accept bare wire, banana plugs, spade lugs, and pin connectors.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlagship Acoustic Suspension Design:\u003c\/strong\u003e Sealed cabinet delivers the most linear and low-distortion bass available, with a gentle 12dB per octave roll-off that is more tolerant of room equalization and boundary proximity than any ported floorstanding alternative.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e13-Inch High-Displacement Woofer:\u003c\/strong\u003e The first acoustic suspension loudspeaker built around a 13-inch driver; features a pulp-paper cone, half-roll rubber suspension, non-resonant die-cast aluminum frame, and a 2-inch flat-wire voice coil for extended excursion at low distortion.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDedicated 5-Inch Midrange Driver in Sealed Sub-Enclosure:\u003c\/strong\u003e Isolated internal enclosure eliminates back-wave contamination from the woofer cavity, preserving the purity and accuracy of the 300Hz to 3,500Hz critical midrange band.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1-Inch Aluminum Dome Tweeter:\u003c\/strong\u003e Soft rubber suspension and precision-machined aluminum faceplate deliver smooth, extended high-frequency reproduction with natural dispersion characteristics above 3,500Hz.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3rd-Order Electro-Acoustic Crossover Networks:\u003c\/strong\u003e 300Hz woofer-to-midrange and 3,500Hz midrange-to-tweeter crossover points, implemented with a thirteen-component network using iron-core inductors and Mylar capacitors for accurate phase and dynamic performance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree-Position Acoustic Balance Control:\u003c\/strong\u003e Rear-panel switch attenuates output above 400Hz by 0dB, -1.5dB, or -3dB, allowing listeners to adapt the speaker's upper-frequency character to suit bright, neutral, or well-damped listening rooms.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReinforced Wide-Baffle MDF Cabinet:\u003c\/strong\u003e 3\/4-inch MDF panels with a heavier 1-inch front baffle and structural internal bracing reduce cabinet resonance and provide a stable, non-resonant acoustic foundation for the 13-inch woofer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBook-Matched Real Wood Veneers:\u003c\/strong\u003e Sold as matched left and right units with mirror-image veneer patterns in English Walnut or West African Mahogany, combining visual symmetry with mid-century modern proportions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded 3-Degree Matte Black Slant Riser Base:\u003c\/strong\u003e Low-profile base angles the driver array toward the listening position, optimizing vertical coverage for seated listeners without any additional stand purchase.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGold-Plated Five-Way Binding Posts:\u003c\/strong\u003e Accept bare wire, banana plugs, spade lugs, and pin connectors for flexible compatibility with all amplifier cable termination types.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e10-Year Manufacturer Warranty:\u003c\/strong\u003e KLH Audio backs the Model Seven with a full decade of coverage, consistent across the entire KLH Model Collection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDesign\u003c\/td\u003e\n      \u003ctd\u003e3-Way Acoustic Suspension Floorstanding Loudspeaker\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLow-Frequency Driver\u003c\/td\u003e\n      \u003ctd\u003e13\" Pulp-Paper Cone, Half-Roll Rubber Suspension, 2\" Flat-Wire Voice Coil, Die-Cast Aluminum Frame\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMidrange Driver\u003c\/td\u003e\n      \u003ctd\u003e5\" Pulp-Paper Cone, Half-Roll Rubber Suspension, Die-Cast Aluminum Frame, Sealed Sub-Enclosure\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHigh-Frequency Driver\u003c\/td\u003e\n      \u003ctd\u003e1\" Aluminum Dome, Soft Rubber Suspension, Machined Aluminum Faceplate\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCrossover Frequencies\u003c\/td\u003e\n      \u003ctd\u003e300Hz (MF, 3rd-Order Electro-Acoustic) \/ 3,500Hz (HF, 3rd-Order Electro-Acoustic)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCrossover Components\u003c\/td\u003e\n      \u003ctd\u003e13-Component Network, Iron-Core Inductors, Mylar Capacitors\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFrequency Response\u003c\/td\u003e\n      \u003ctd\u003e38Hz -

It is the flagship model in the KLH Model Collection, featuring a 13-inch woofer, a 5-inch dedicated midrange driver in a sealed sub-enclosure, and a 1-inch aluminum dome tweeter. Frequency response is 38Hz to 20kHz ±3dB with an in-room sensitivity of 91dB and a nominal impedance of 4 ohms. The Model Seven is sold as matched left and right individual units; two must be purchased to form a stereo pair.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the KLH Model Seven compare to the KLH Model Five?\u003c\/h3\u003e\n\u003cp\u003eThe KLH Model Seven and Model Five both use acoustic suspension sealed-cabinet designs, thirteen-component crossover networks with iron-core inductors and Mylar capacitors, aluminum dome tweeters, and the three-position Acoustic Balance Control. The Model Seven scales up every dimension: a 13-inch woofer versus the Model Five's 10-inch, a 5-inch midrange versus a 4-inch, a thicker 1-inch front baffle, deeper bass extension to 26Hz versus 32Hz (-10dB), higher power handling of 250 watts versus 200 watts, and a higher maximum SPL of 115dB versus 112.3dB. The Model Seven also introduces a 3rd-order crossover topology and houses the midrange in its own sealed internal sub-enclosure, a structural refinement not present in the Model Five. Compared to ported competitors such as the Klipsch Forte IV, Wharfedale Elysian 2, or MoFi Electronics SourcePoint 888, the Model Seven is distinguished by its sealed-box bass linearity and superior close-wall placement tolerance.\u003c\/p\u003e\n\n\u003ch3\u003eCan the KLH Model Seven be placed near a wall?\u003c\/h3\u003e\n\u003cp\u003eYes. The acoustic suspension sealed cabinet of the Model Seven has no rear-firing port, making it substantially more forgiving of close-wall placement than ported floorstanding speakers of comparable driver size. KLH and independent dealers recommend a starting distance of approximately 6 to 24 inches from the rear wall, and users have confirmed excellent results at much shorter distances without bass coloration. The wide front baffle also reduces side-wall reflections, further improving imaging in typical living-room setups.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the dedicated midrange sub-enclosure in the KLH Model Seven?\u003c\/h3\u003e\n\u003cp\u003eThe 5-inch midrange driver in the KLH Model Seven is mounted in its own sealed internal sub-enclosure within the main cabinet. This acoustic isolation prevents the pressure waves generated by the large 13-inch woofer from entering the midrange driver cavity, eliminating back-wave coloration and intermodulation artifacts that can degrade clarity in the 300Hz to 3,500Hz vocal and instrumental frequency range. The sealed sub-enclosure approach is a more complex and costly construction method than open-baffle or shared-cavity midrange mounting, and it contributes directly to the Model Seven's coherence and dynamic resolution across the critical midrange band.\u003c\/p\u003e\n\n\u003ch3\u003eWhat amplifier power does the KLH Model Seven require?\u003c\/h3\u003e\n\u003cp\u003eThe KLH Model Seven is rated for 20 to 250 watts of amplifier power per channel with a 4-ohm nominal impedance. Its in-room sensitivity of 91dB means it reaches satisfying listening levels with relatively modest amplifier power, but the 4-ohm load requires an amplifier that is stable at this impedance. Solid-state integrated amplifiers and stereo power amplifiers rated at 4 ohms are the recommended pairing; tube amplifier users should use the 4-ohm output transformer taps.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the KLH Model Seven in Buffalo, NY?\u003c\/h3\u003e\n\u003cp\u003eThe KLH Model Seven is available at Vinyl Sound, an authorized KLH Audio dealer located in Buffalo, New York. Vinyl Sound carries the full KLH Model Collection and can assist with system matching and auditioning. The Model Seven is sold as individual matched left and right units, so one of each must be purchased to assemble a complete stereo pair.\u003c\/p\u003e\n\n\u003ch3\u003eWhat finish options are available for the KLH Model Seven?\u003c\/h3\u003e\n\u003cp\u003eThe KLH Model Seven is available in English Walnut and West African Mahogany real wood veneers, both applied as book-matched panels to maintain visual grain symmetry across the cabinet faces. Each finish is paired with a magnetic low-profile grille cloth, and additional grille options are available separately to allow customization independent of the cabinet veneer. The matte black slant riser base is included with every unit regardless of finish.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the KLH Model Seven need a subwoofer?\u003c\/h3\u003e\n\u003cp\u003eFor most listening rooms and music genres, the KLH Model Seven does not require a subwoofer. Its sealed 13-inch woofer extends to 38Hz at ±3dB and -10dB at 26Hz, covering the fundamental frequencies of bass guitar, kick drum, double bass, organ, and orchestral low brass. The sealed enclosure's gradual 12dB per octave roll-off below resonance also pairs exceptionally well with room gain in typical domestic spaces, meaning perceived bass extension often exceeds the anechoic specification. For home theater use or listeners who prioritize sub-20Hz impact, a quality subwoofer can be integrated cleanly thanks to the Model Seven's predictable sealed-box roll-off behavior.\u003c\/p\u003e","brand":"Vinyl Sound USA","offers":[{"title":"West African Mahogany","offer_id":53329935827251,"sku":null,"price":2999.0,"currency_code":"USD","in_stock":true},{"title":"English Walnut","offer_id":53329935860019,"sku":null,"price":2999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/0293\/0739\/files\/KLHModel7FloorstandingSpeakers_Each.png?v=1778177906","url":"https:\/\/vinylsound.com\/products\/klh-model-7-floorstanding-speakers-each","provider":"Vinyl Sound USA","version":"1.0","type":"link"}
