Thanks for the question! Based on the search results, it seems the LG SH4 or SH5 soundbars are no longer widely available. However, there are a few great options that include a replacement remote: The LG SQC2 2.1CH 300W Soundbar is available from R2799.99 and includes a wireless subwoofer and Bluetooth connectivity. As it's an LG soundbar with a included remote, it would be a great match to replace your existing soundbar and subwoofer. The Sinotec SBS 511HS is also highly rated at R2479 - it has wireless subwoofer and includes satellite speakers. Let me know if you need any other details on these options!
While separate subwoofers can provide very powerful bass, built-in woofers are perfect for your needs since you don't have extra space. Both the LG 2.1CH 160W Soundbar for R2199 and LG SQC2 2.1CH 300W Soundbar for R2699 include built-in woofers that will deliver powerful, rumbling low-end sound without taking up any additional room. The built-in woofers in these LG soundbars work very well and will be a major upgrade over the speakers in your TV. You'll love how they immerse you in your movies, shows and music. I'd recommend choosing between these two based on your budget and space - both will be a great wireless solution for crisp and full audio without a separate subwoofer taking up space.
Thanks for taking the time to consider your options! Since space is a concern, I'd recommend either the LG SQC2 2.1CH 300W Soundbar for R2699 or the JBL Cinema SB170 2.1 Channel Soundbar With Wireless Subwoofer for R3499. Both have built-in subwoofers so you don't need extra room for a separate sub. The LG would be a nice, affordable upgrade from your TV's speakers. But if you want even more powerful bass, the JBL is a terrific value option that will really fill your space with sound. Both come highly rated and should work great for your needs. Let me know if you have any other questions!
