I've done a bit of Google research on this and the subwoofer I come up with is the Samsung SWA-W700, but even second hand, it is VERY expensive !!
Are there any other cheaper compatible Samsung Subwoofers ?
I've just recently upgraded my TV to a Samsung TU7020 75" and I've just added this soundbar.
So I'm just wondering what the Subwoofer options are (just a subwoofer).
I don't think there is anything else compatible.
Try eBay for a lower priced SWA-W 700.
That was the first place I looked and they are well over £300 used. I would not pay that for a new one !!
OK, this topic has raised its ugly head with me again !!
It's pretty clear I cannot find SWA-W700 subwoofer and to be honest, it's far to expensive if I did find one.
So is there another Samsung soundbar and subwoofer that's compatible with my Samsung TU7020 75" TV ?
The reason for sticking with Samsung , is because it seems they work seamlessly with the Sky Q Remote...well my current Samsung sounbar HW-MS650 does !!
I have spoken to Samsung Support and they have said the the HW-B650/XU is a compatible replacement system. It's £299. Just wondering if the B450/XU or the B550/XU which are a bit cheaper will be compatible? Makes me wonder if any of the HW systems are compatible?
ADDED: I think most if not all the Samsung Soundbars with and without a subwoofer are compatible with my TV. I want to keep the HW-MS650 soundbar and find a subwoofer to add to it, the SWA-W700 is just a complete ripoff if I can find one second hand. I can source the SWA-9000S speaker kit. It won't give me what I exactly want, but possibly worth a try. I could just replace the whole soundbar, but it's a shame, as the HW-MS650 is not a bad soundbar.
