==== No home theater is complete without the .1 channel – the subwoofer – for deep bass and LFE (low-frequency effects). In a WiSA system, the subwoofer also needs to be WiSA-certified (or connected via a WiSA receiver) to receive the wireless audio. Several good wireless subwoofers are available: ====
* Klipsch Reference Wireless RW-100SW: This is a 10-inch wireless subwoofer in Klipsch’s WiSA lineup. It features a 10” copper Cerametallic driver powered by a built-in amplifier (around ~150 W RMS) in a ported enclosure. Being WiSA-certified, it pairs directly with the SoundSend (or other WiSA transmitters) and plays the LFE channel without any cable runs. Klipsch touts that with its 10" driver, the RW-100SW “delivers Klipsch signature low frequencies to create a heart-stopping home theater sound experience”wisatechnologies.com<ref>{{cite web|title=wisatechnologies.com|url=https://www.wisatechnologies.com/speakers#:~:text=Reference%20Wireless%20RW|publisher=wisatechnologies.com|access-date=2025-11-29}}</ref>. In practice, this sub is quite capable for most living rooms – it hits hard for movie explosions or musical bass lines, and you can position it freely (just a power outlet needed). If you’re using the Klipsch RW series speakers, this sub naturally complements them, but it will work with any WiSA speaker set. It’s one of the more affordable WiSA subs, offering solid performance for the price.
* Bang & Olufsen Beolab 19: For those seeking a combination of high-end performance and unique design, B&O’s Beolab 19 is a wireless subwoofer masterpiece. It has a distinctive geometric shape (dodecahedral design) and dual 8-inch drivers in a force-canceling configuration. The Beolab 19’s selling point – beyond its looks – is tight, musical bass response and very high output for its size. B&O describes that the BeoLab 19 delivers exceptional bass, adding mood and depth to both stereo and cinematic experiences, and thanks to WiSA you have the freedom to place it wherever it sounds best in your roomwisatechnologies.com<ref>{{cite web|title=wisatechnologies.com|url=https://www.wisatechnologies.com/speakers#:~:text=Beolab%2019|publisher=wisatechnologies.com|access-date=2025-11-29}}</ref>. This sub can dig plenty deep and maintain precision (great for both movies and music). However, as with other B&O products, the cost is steep (it’s a luxury sub, often priced in the mid-thousands). It can be an amazing addition if budget permits, especially paired with other Beolab speakers for a completely cable-free high-end setup.
* Harman Kardon Citation Sub S: The Citation Sub S is a compact wireless sub (8-inch driver) originally designed to complement HK’s Citation soundbar system. It is WiSA-compatible (the Citation Surround/Tower use WiSA for wireless audio), so in theory it can be paired with a SoundSend as well. The Sub S is relatively small and stylish (with a fabric-covered exterior), making it apartment-friendly. HK advertises that adding the Sub S will “infuse your home audio with a grounding layer of deep, rich bass” and completes the home theater when used with Citation Surround speakerswisatechnologies.com<ref>{{cite web|title=wisatechnologies.com|url=https://www.wisatechnologies.com/speakers#:~:text=Citation%20Sub%20S|publisher=wisatechnologies.com|access-date=2025-11-29}}</ref>. In an open 5.1 system, the Citation Sub S could be an option if you need a smaller form-factor subwoofer – though you might give up some deep extension and output compared to larger subs like the Klipsch. (Ensure the SoundSend’s app is updated; it should recognize the Sub S as the LFE channel device if it’s WiSA-certified.)
'' Others / Notes: Platin, who makes the SoundSend, also offers WiSA subs in their speaker bundles (e.g. the Platin Monaco and Milan systems include a wireless sub). For example, the Platin Monaco system’s sub is a down-firing 8” unit tuned by THX – not sold separately typically, but if you see it available, it’s a decent budget choice for smaller roomswhathifi.com<ref>{{cite web|title=whathifi.com|url=https://www.whathifi.com/reviews/platin-monaco-51-wisa-speaker-system#:~:text=Platin%20Monaco%205,Digital%2B%2C%20Dolby%20TrueHD%2C%20Dolby|publisher=whathifi.com|access-date=2025-11-29}}</ref>cepro.com<ref>{{cite web|title=cepro.com|url=https://www.cepro.com/news/hands-on-platin-monaco-5-1-2-wisa-system-uses-dolby-atmos-to-create-affordable-cinematic-experience/111754/#:~:text=Platin%20Monaco%205,%C2%B7%20Subwoofer%20did|publisher=cepro.com|access-date=2025-11-29}}</ref>. Another exotic WiSA sub is the Goldmund'' wireless sub (high-end Swiss audio brand), but those are extremely expensive and rare. The good news with WiSA is interoperability: you can choose any WiSA subwoofer and it will work with any WiSA transmitter/speakers. So, you could use (for example) the Klipsch RW-100SW sub alongside Piega or Buchardt speakers, or vice versa. The SoundSend transmitter will automatically assign the LFE channel to whatever device identifies itself as a subwoofer in the setup. In fact, SoundSend even supports dual subwoofers if you want to run 5.2 – users have reported the app allows two subs to connect (it will still label the setup 5.1, but emit bass from two subs)reddit.com<ref>{{cite web|title=reddit.com|url=https://www.reddit.com/r/hometheater/comments/kfbzbw/soundsend_wisa_w_klipsch_speakers/#:~:text=I%20had%20to%20do%20this,After|publisher=reddit.com|access-date=2025-11-29}}</ref>reddit.com<ref>{{cite web|title=reddit.com|url=https://www.reddit.com/r/hometheater/comments/kfbzbw/soundsend_wisa_w_klipsch_speakers/#:~:text=think%20you%20have%20it%2C%20just,After|publisher=reddit.com|access-date=2025-11-29}}</ref>. Using two subs can help distribute bass more evenly in a room, though one good sub is sufficient for most situations.

For most people, the Klipsch RW-100SW is the easy recommendation for a WiSA sub – it’s reasonably priced, hits hard, and is proven to work well in WiSA home theaterswisatechnologies.com<ref>{{cite web|title=wisatechnologies.com|url=https://www.wisatechnologies.com/speakers#:~:text=Reference%20Wireless%20RW|publisher=wisatechnologies.com|access-date=2025-11-29}}</ref>. If you’re building a higher-end system, the B&O Beolab 19 is a standout (if budget allows) with its combination of style and performancewisatechnologies.com<ref>{{cite web|title=wisatechnologies.com|url=https://www.wisatechnologies.com/speakers#:~:text=Beolab%2019|publisher=wisatechnologies.com|access-date=2025-11-29}}</ref>. And if space is at a premium, the Citation Sub S or Platin’s compact subs could do the job. Whichever you choose, a properly integrated sub will dramatically enhance the impact and fullness of your 5.1 audio.
