Its DPC-Array technology ensures optimized sound directivity and timbre matching across a wide frequency range.\u003c\/strong\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003eThe R7i-LR employs a Directivity Pattern Control (DPC) array, which utilizes three 26mm silk dome tweeters arranged to enhance mid-to-high frequency directivity while maintaining a consistent tonal balance. This innovative design is anchored in physics, leveraging COMSOL acoustic modeling to meticulously design each component for optimal performance, resulting in a frequency response range of 42 Hz to 32 kHz, with a sensitivity of 89.9 dB. The custom bass drivers, constructed from high-performance fiber (HPF) diaphragms, bolster low-frequency predictability, contributing to a dynamic range capable of reaching a SPL of 115.9 dB peak at 1 meter. The cabinet’s acoustic suspension alignment ensures controlled resonance, further solidifying the R7i-LR's capability in both home theater and media room applications.\u003cbr\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDPC-Array Technology:\u003c\/strong\u003e This unique configuration of three tweeters allows for superior directivity control and consistent tonal balance, ensuring clarity in vocal and treble frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Woofers:\u003c\/strong\u003e Made from HPF diaphragms, the woofers deliver predictable low-frequency performance essential for multi-channel audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Suspension Design:\u003c\/strong\u003e The enclosure minimizes distortion and enhances sound quality by controlling the back pressure of the drivers, resulting in improved bass response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Frequency Range:\u003c\/strong\u003e With a performance envelope of 42 Hz to 32 kHz, the R7i-LR reproduces both deep bass and delicate high frequencies with exceptional accuracy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Acoustic Modeling:\u003c\/strong\u003e The implementation of COMSOL simulations ensures each component is engineered to deliver targeted sound performance, meeting rigorous acoustic standards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnclosure Alignment: Acoustic Suspension\u003c\/li\u003e\n\u003cli\u003eDriver Compliment: DPC-Array: 26mm(3) Silk Dome, Woofers: 165mm(4) HPF Diaphragms\u003c\/li\u003e\n\u003cli\u003eSensitivity: 89.9 dB \/ 2.83v \/ 1.0m\u003c\/li\u003e\n\u003cli\u003eImpedance: 4Ω nominal \/ 3.6Ω min\u003c\/li\u003e\n\u003cli\u003eFrequency Response (±2.0dB Window): 80 - 20kHz\u003c\/li\u003e\n\u003cli\u003eFrequency Response (-10dB): 42 - 32kHz\u003c\/li\u003e\n\u003cli\u003eTypical In-Room Bass Extension: 35Hz\u003c\/li\u003e\n\u003cli\u003eDimensions (HxWxD): 1032.0 x 293.0 x 120.8 mm (40.6 x 11.5 x 4.8 in)\u003c\/li\u003e\n\u003cli\u003eWeight: 23.1 kg (50.8 lbs)\u003c\/li\u003e\n\u003cli\u003eRecommended Amplifier Power: 100 - 400W RMS\u003c\/li\u003e\n\u003cli\u003eSPL Capability @1m (100-20kHz): 115.9 dB Peak\u003c\/li\u003e\n\u003cli\u003eAvailable Finishes: Matte Black Aluminum with White Grille\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Perlisten Audio","offers":[{"title":"Default Title","offer_id":42704740286577,"sku":"R7i-LR","price":4395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0571\/7617\/files\/Perlisten_R7I-LR_View1_11d33752-cc44-45b5-9b7f-f3b493eaf4b1.jpg?v=1774187436","url":"https:\/\/shopodsy.com\/products\/perlisten-audio-r7i-lr-in-wall-speaker","provider":"ODSY","version":"1.0","type":"link"}
