Specifications: Dimensions: 14\" H x 4.1\" W x 4.1\" D; Generator Type: Ultra Low Frequency (ULF) RF Pulse Generator. Description: The Synergistic Research FEQ X4 is an acoustic field generator engineered to neutralize ambient atmospheric interference in your listening space. Operating as a single-channel ULF pulse generator, it emits a specialized frequency field that overpowers local RFI and EMI. By stabilizing the surrounding RF environment, the FEQ X4 creates a pristine acoustic backdrop, enabling your audio system to reproduce music with enhanced clarity, expanded soundstage geometry, and natural harmonic fullness.\n\nReviews and audio critics consistently praise the FEQ X4 for providing an immediate, noticeable lift in system performance. Listeners highlight a dramatically lower noise floor, allowing micro-details, vocal nuances, and delicate instrumental decays to emerge clearly. Reviewers frequently note a wider, deeper three-dimensional soundstage with superior image placement and enhanced midrange presence. Switching the unit off reportedly results in an immediate loss of soundstage focus, proving its active role in delivering a lifelike listening experience.\n\nControlling room interactions and environmental interference is essential for unlocking an audio system's true potential. The FEQ X4 solves this challenge by actively purifying the listening environment without requiring bulky room treatments. By delivering consistent, late-night sound quality at any hour, it ensures your music always plays with the clarity, warmth, and holographic depth your high-end setup was designed to produce.","brand":"Synergistic Research","offers":[{"title":"Default Title","offer_id":67603008192793,"sku":"98855","price":529.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/98855-3.jpg?v=1790730816","url":"https:\/\/tmraudio.com\/products\/synergistic-research-feq-x4-frequency-equalizer-2","provider":"The Music Room","version":"1.0","type":"link"}
