Following. I found the bass to be quite underwhelming too.

Has this problem solved? How are you experiencing the bass now?

The Arc bass sounds perfectly fine to me (using LG C9 TV) ...and is even better since adding surrounds and the newer sub. The Christmas blu-tack helps stops the ornaments vibrating off the shelves ...and the neighbours ‘for-sale’ notices are just a reflection on how good it sounds.

Now the real question here is ...should I add a ‘second sub’ and just sell all these ornaments? I’m just not sure the blu-tack will be upto the job, with two subs?
