It uses a single 18-inch long-excursion woofer in a bass-reflex cabinet to deliver substantial low-end energy down to 30Hz, making it an effective solution for extending the impact and depth of compatible VHA systems.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe enclosure is optimized using BEM-type acoustic simulations to reduce port turbulence and cabinet resonance, helping the subwoofer maintain strong output with controlled performance. Its cabinet is constructed from 18mm birch plywood and finished in a durable black anti-scratch coating, while the front is protected by a powder-coated perforated steel grille with protective fabric.\u003c\/p\u003e\r\n\r\n\u003cp\u003eFor practical deployment, the cabinet includes multiple aluminum handles, provision for four 100mm swivel casters, and two M20 stand sockets for horizontal or vertical use. Integrated hardware also supports ground stack configurations in conjunction with compatible VHA models, making the unit suitable for professional rental inventories and fixed system deployments.\u003c\/p\u003e\r\n\r\n\u003cp\u003eOnboard control is handled through an OLED display and push encoder, giving users direct access to settings and presets. The VHA 118 SN is also designed for remote system management through FBT INFINITO software over TCP\/IP. According to the provided product information, the VHA 118 SN shares the same core characteristics as the VHA 118 SND version, but does not include Dante functionality.\u003c\/p\u003e\r\n\r\n\u003ch3\u003eVHA 118 SN Features\u003c\/h3\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eBass-reflex amplified subwoofer\u003c\/li\u003e\r\n  \u003cli\u003e460mm (18-inch) high-excursion B\u0026amp;C woofer with 100mm (4-inch) coil\u003c\/li\u003e\r\n  \u003cli\u003eFrequency response from 30Hz to 100Hz\u003c\/li\u003e\r\n  \u003cli\u003e2500W RMS Class D amplifier with switching power supply\u003c\/li\u003e\r\n  \u003cli\u003eTCP\/IP network interface with AES70 compatibility\u003c\/li\u003e\r\n  \u003cli\u003eEthercon RJ45 input and output for daisy-chain connections\u003c\/li\u003e\r\n  \u003cli\u003eRemote control via INFINITO System Management Suite\u003c\/li\u003e\r\n  \u003cli\u003eOLED display and push encoder for onboard control\u003c\/li\u003e\r\n  \u003cli\u003eNeutrik PowerCON IN and LINK power connectors\u003c\/li\u003e\r\n  \u003cli\u003e18mm birch plywood cabinet with anti-scratch varnish\u003c\/li\u003e\r\n  \u003cli\u003eTwo M20 stand sockets for horizontal or vertical use\u003c\/li\u003e\r\n  \u003cli\u003eFour FBT aluminum handles and provision for 4 x 100mm (4-inch) swivel casters\u003c\/li\u003e\r\n  \u003cli\u003eIntegrated mechanics compatible with VHA 406ND and VHA 112SND for ground stack configurations\u003c\/li\u003e\r\n  \u003cli\u003eExtremely robust grille with protective fabric\u003c\/li\u003e\r\n  \u003cli\u003eIdeal for reinforcing and extending the low range of the VHA system\u003c\/li\u003e\r\n  \u003cli\u003ePreset support for cardioid configurations\u003c\/li\u003e\r\n  \u003cli\u003eHigh-brightness blue front LED for remote identification\u003c\/li\u003e\r\n  \u003cli\u003eIntelligent forced ventilation system\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eVHA 118 SN Specifications\u003c\/h3\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eConfiguration: Single Reflex\u003c\/li\u003e\r\n  \u003cli\u003eLow Frequency Woofer: 1 x 18-inch \/ 4-inch coil\u003c\/li\u003e\r\n  \u003cli\u003eFrequency Response: 30Hz preset dependent\u003c\/li\u003e\r\n  \u003cli\u003eMaximum SPL (Cont\/Peak): 137 \/ 143dB half space\u003c\/li\u003e\r\n  \u003cli\u003eDispersion: Omnidirectional\u003c\/li\u003e\r\n  \u003cli\u003eInput Connector: 2 x XLR In \/ Out\u003c\/li\u003e\r\n  \u003cli\u003eAC Power Requirements: 650 VA\u003c\/li\u003e\r\n  \u003cli\u003ePower Cord Length: 5m\u003c\/li\u003e\r\n  \u003cli\u003eDimensions: 23.9 x 27.6 x 28.3 in (606 x 700 x 720 mm)\u003c\/li\u003e\r\n  \u003cli\u003eNet Weight: 143.3 lb (65 kg)\u003c\/li\u003e\r\n  \u003cli\u003eTransport Weight: 165.3 lb (75 kg)\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"FBT","offers":[{"title":"Default Title","offer_id":51832381899034,"sku":"116918","price":4299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/fbt-vha-118-sn--18in---143db--powered-ground-subwoofer_f2d22549-7ff6-4a97-8303-af381de67299.webp?v=1773680144","url":"https:\/\/squarecable.com\/products\/fbt-vha-118-sn-18in-143db-powered-ground-subwoofer","provider":"SquareCable","version":"1.0","type":"link"}
