This \nis particularly relevant for film sound, LFE effects, electronic music, \norchestral passages, and other bass-intensive content.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cbr\u003eApp control for easy \nadjustment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe SVS Subwoofer Control App is compatible with Apple iOS, Google Android, and Amazon \nFire.

This results in a \nsignificantly fuller, more dynamic sound with palpable bass, more spaciousness, and \na more intense listening experience.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eActive or passive subwoofer: What is better here?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe SB-17 Ultra R|Evolution is an active subwoofer with an integrated STA-2800 Class-D amplifier. For \nthis product, the active design makes sense because the \namplifier, DSP, protection functions, app control, and drivers are directly \nmatched and integrated.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eWhat room size does the subwoofer require?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWe recommend a room size of 25 \nm² to 60 m² (medium to very large \nrooms) for the subwoofer.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eWhere should a subwoofer not be placed?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe subwoofer should not be placed near water, heat sources, or without \nsufficient ventilation in confined furniture. Ventilation openings must not be \nblocked, as the amplifier needs to be cooled.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eCorner placement can be good, but not always\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCorner placement can reduce bass cancellations and make the bass sound more \npowerful. At the same time, depending on the listening position, it can lead to boomy bass; \nin that case, more distance to the walls or adjustment via the control functions helps.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eGood positions in the room\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA front placement between or next to the front speakers \nsupports the blending with main speakers and center channel. A \nside wall position can also work if accuracy and performance in the \nroom come together better there.\u003c\/p\u003e\u003cp\u003eFurthermore, we recommend a minimum distance of 10 to 15 cm from the wall. Since \nthe subwoofer is constructed in a sealed enclosure without a rear bass reflex port, \nit can be placed significantly more flexibly near a wall than a \ncomparable bass reflex model like the PB-17 Ultra.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eTwo subwoofers for more even bass\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe \noperation of two or more subwoofers can improve frequency response, bass distribution, and \nperformance in the listening area.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eConnections for home theater and stereo\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFor home theater setups, the LFE connection via RCA or XLR is key. In \nstereo systems, left and right line-level or balanced \nXLR outputs of a preamplifier can be connected to the subwoofer's \ninputs.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eWireless option with separately available adapter\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA USB port provides power for the SVS SoundPath Wireless Audio Adapter, \nwhich is sold separately. This eliminates the need for the connection cable from the source device to the \nsubwoofer.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eDoes SVS make good subwoofers?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe SB-17 Ultra R|Evolution shows SVS's clear focus on \nsubwoofer technology: large long-throw driver, powerful amplifier, high-resolution \nDSP, app control, stable MDF construction, Iso-Elastomer feet, and a 5-year \nwarranty. The strength here lies not only in performance, but also in \ncontrol, adjustability, and integration.\u003c\/p\u003e","brand":"SVSound","offers":[{"title":"Black Oak","offer_id":54748344287573,"sku":"60166","price":3699.0,"currency_code":"EUR","in_stock":true},{"title":"Piano Gloss Black","offer_id":54748344320341,"sku":"60167","price":3699.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/9715\/6693\/files\/IMG60166_169802.jpg?v=1787662739","url":"https:\/\/fidelity-hh.de\/en\/products\/sb-17-ultra-r-evolution","provider":"Fidelity","version":"1.0","type":"link"}
