## Description

330W Peak | 200W RMS | 120dB Extreme Loudness | 40Hz Deep Bass The X20 portable Bluetooth speaker delivers massive power with 330W peak and 200W RMS, reaching an ear-catching 120dB for room-filling, party-ready volume. The three-way acoustic system (7.5"x4.5" subwoofer, two 3.5" mid-woofers, two 1.1" tweeters) produces deep bass down to 40Hz, clear vocals, and crisp treble. Three passive radiators on the left, right, and back, combined with a DSP chip, ensure thunderous bass resonance and real-time audio processing for hi-fi sound across all genres. WDSP2.0 Exclusive Algorithm (Sound Master Tuning) Customize your sound with the free W-KING APP. The WDSP2.0 acoustic algorithm dynamically adjusts frequency response in real time, delivering studio-grade clarity, deeper bass, and fatigue-free listening. Boost or cut specific frequencies, or use built-in EQ presets for music, movies, or games. Wireless Stereo Pairing (660W Peak + 400W RMS) Pair two X20 speakers wirelessly to create a powerful 660W PEAK (400W RMS) system with incredible stereo sound. Double the power and enjoy a wider, more immersive soundstage. IP67 Waterproof & Dustproof Rated IPX7 waterproof and IP6 dustproof, the X20 withstands pools, beaches, rain, and dusty trails — perfect for outdoor adventures and social gatherings. 24-Hour Playtime & Fast Charging (60W, ~3 Hours) Enjoy all-day playback on a single charge. Fast charging support (up to 60W) gets you back to full power in about 3 hours. The speaker also features emergency device charging via USB port to charge your smartphone or tablet. Bluetooth 5.4 & Multiple Connections Bluetooth 5.4 offers better sound quality, lower latency, longer range, and less interference. Also supports OTG (direct wired connection to phones/tablets), AUX input, TF card, and USB flash drive.

Review: W-KING X20: Not for Weak Arms or Low Volume Fans” - This beast is heavy, and the oversized handle doesn’t help much even with a strap, it demands serious muscle. The bass only shows up at full volume, and while it’s deep, it’s not punchy. Definitely built for energetic users who don’t mind the weight and size.
Review: Wking x20 ... wking fa centro - Ho ordinato questo speaker perché ha l'ingresso microfono ma ero pronto a restituirlo e prendere il tribit storm blast se il suono non fosse stato bello davvero Questo speaker suona bene, superfluo usare la formula " bassi sono avvolgenti , medi chiari, alti cristallini" ...la diamo per scontato in questa fascia, l'armonia complessiva del suono è bella e la potenza è notevole Insomma...cassa da goduria L'ingresso microfono funziona bene Senza infamia e senza lode , il serraggio dello spinotto jack ha un po' di gioco ma non sembra dare problemi Non ha effetti voce e nemmeno regolazione guadagno solo c'è solo la regolazione del volume tramite app Si può usare per un karaoke improvvisato o per parlare in pubblico, e naturalmente per amplificare chitarra , ma non è certo la funzione principale. Apprezzo molto la cinghia per tracolla e gli occhielli d'aggancio a scomparsa Giudizio finale....una bella cassa , notevole nelle dimensioni , qualità del suono, qualità costruttiva e potenza Non è un caso che YouTube sia pieno di recensioni positive Spendo due parole per l'app che la trovo fatta bene, finalmente wking non ci obbliga a scegliere tra le due equalizzazioni preimpostate troppo estreme Indor che fa risaltare i bassi ma attenua troppo le frequenze della voce e il suono appare chiuso outdoor che rende il suono squillante ma accentua troppo i medioalti dando una sfumatura citofonale al suono. In questo speaker il suono è bilanciato e aperto, molto dinamico e con tanta spazialità Va già benissimo l'equalizzazione in flat ma sono belle le configurazioni preimpostate dedicate al genere che vuoi ascoltare e si può usare l'equalizzatore grafico sia per intervenire direttamente sul suono che per memorizzare le equalizzazioni che andiamo a creare Rapporto qualità/prezzo ...ottimo

### ⭐⭐⭐⭐⭐ Excelente equipo seguiré probando!
*by R***S on 12 August 2024*

Si se escucha fuerte pero no me sorprende ya que tengo un equipo de audio en casa que tiene mucho más sub woffer la w king x20 suena bien y no distoriona lo mejor es que tiene ecualizador y lo ajustas a tu gusto, seguiré probando el equipo en mi trabajo ya que para eso lo compre para usarlo en el taller. Lo malo es que no trae cuadro para cargar pero pues eso ya lo sabía, si carga de 3 a 3.5 horas con un cargador de 60w la carga obviamente no dura 24 horas con volumen al 100 % la estuve probando y si baja la batería usándola al 100%. En general solo queda seguir probando el equipo lo más probable es que si me quede con el.
