Its innovative design facilitates remarkable sound staging and clarity across a wide frequency spectrum.\u003c\/strong\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003eThe Perlisten Audio R4b Bookshelf Speaker employs a 3-way acoustic suspension design that leverages a DPC-Array incorporating three 26mm silk dome tweeters. This array allows for focused directivity control, enhancing soundstage coherence and spatial imaging by minimizing off-axis frequency response errors. The utilization of a proprietary 165mm HPF pulp diaphragm woofer, which has undergone two years of development, ensures improved transient response and dynamic headroom, offering a significant leap in low-frequency fidelity. Coupled with a sensitivity of 84.6 dB and a nominal impedance of 4Ω, the R4b is engineered to work effectively within a wide amplifier power range, achieving SPL capabilities up to 107.6 dB. The design also emphasizes a frequency response linearity of +\/-1.5 dB from 80 Hz to 20 kHz, ensuring that critical midrange and treble frequencies are reproduced with accuracy and minimal coloration.\u003cbr\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDPC-Array Technology:\u003c\/strong\u003e Incorporates three 26mm silk dome tweeters for improved directivity and sound coherence, minimizing phase distortion across the audible range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary HPF Pulp Woofer:\u003c\/strong\u003e A uniquely developed 165mm woofer increases efficiency and transient response compared to traditional materials, enhancing low-frequency performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Way Acoustic Suspension Design:\u003c\/strong\u003e A configuration that provides optimal bass extension and control, allowing for deeper and more defined low frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Frequency Response:\u003c\/strong\u003e Achieves flat response from 80 Hz to 20 kHz +\/- 1.5 dB, ensuring accurate audio reproduction across a variety of content.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Dimensions:\u003c\/strong\u003e At 382 x 230 x 236 mm, the R4b is designed to fit neatly in smaller spaces while still delivering robust sound.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for Compatibility:\u003c\/strong\u003e With a recommended amplifier power of 50 - 200W RMS, it integrates seamlessly into a variety of audio systems, maintaining performance integrity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimensions (HxWxD): 382 x 230 x 236 mm (15.0 x 9.0 x 9.3 inches)\u003c\/li\u003e\n\u003cli\u003eWeight: 9.5 kg (20.9 lbs)\u003c\/li\u003e\n\u003cli\u003eSensitivity: 84.6 dB \/ 2.83v \/ 1.0m\u003c\/li\u003e\n\u003cli\u003eImpedance: 4Ω nominal \/ 3.8Ω min\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 45 - 32 kHz (-10dB)\u003c\/li\u003e\n\u003cli\u003eTypical In-Room Bass Extension: 38 Hz\u003c\/li\u003e\n\u003cli\u003eSPL Capability @1m (100-20kHz): 107.6 dB peak\u003c\/li\u003e\n\u003cli\u003eRecommended Amplifier Power: 50 - 200W RMS\u003c\/li\u003e\n\u003cli\u003eCertification: THX Ultra\u003c\/li\u003e\n\u003cli\u003eAvailable Finishes: Piano Black\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Perlisten Audio","offers":[{"title":"High Gloss Black","offer_id":43088190734449,"sku":"R4B-HGB","price":2695.0,"currency_code":"USD","in_stock":true},{"title":"High Gloss White","offer_id":43088190767217,"sku":"R4B-HGW","price":2695.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0571\/7617\/files\/R4b_P4_d23c8abf-2378-46a2-b9d3-eeaceacc7920.png?v=1774187490","url":"https:\/\/shopodsy.com\/products\/perlisten-audio-r4b-bookshelf-speaker-1","provider":"ODSY","version":"1.0","type":"link"}
