Yes, some of the products in the search results could be connected to your JVC 5.1 home theater system. The Jvc XS-N629PB 2.0 Channel Speaker System for R5399 would be a great option to add additional speakers to your existing JVC setup. It comes with 2 additional speakers that can easily connect to the remaining channels on your JVC receiver. The HISENSE HS212 2.1 Ch Soundbar With Wireless Subwoofer Home Theater System for R2250 is another good option, as it adds more sound channels with a wireless subwoofer for enriched bass. I hope these suggestions are helpful for expanding your JVC home theater. Let me know if you need any other recommendations.
