I recently found out that my all in 1 Sennheiser Ambeo Soundbar has the ability for me to add a subwoofer to it. As a result, I am now looking for a good subwoofer to pair with the soundbar. \n\n\nI do have neighbors as I live on the 5th floor. So I am not looking to make anybody angry. However, I do feel like the soundbar is missing that punch. \n\nFrom my tv to my sofa is about 15 ft. \n\nMy tv is caddy corner, I have a custom-built fireplace on a swivel door directly under the tv. \n\nmy budget is about $600 max. I believe I need wireless, as I think the only place I can put the sub is on either side of the sofas or behind the sofa. \n\nI am a complete newbie to subwoofers so any advice will be much appreciated.
