JBL Soundbar 1000 woofer

I have had plenty of experience with subs going back almost 40 years. There is no real problem with the sub, it distorts at higher volume level. I asked JBL if I could substitute the whole of the next up in the line that has a 12 inch sub. They gave an answer that sounds like they did not know what would happen. I should have brought the top of line BAR 1300.  I am sure I could replace the built in 10 inch driver with a better quality driver than the stock one. 

Sound bars are for girlfriends. Buck up and get a pair of speakers and a subwoofer and do it right. 

No can do. do not have the space or the money to set up a surround set up. I am in a Nursing Home, my LG tv and JBL BAR1000 ix opposite the wall in front of my bed. It sounds pretty good for what it is, in my small room. I can take off the end speakers from soundbar for wireless surround and have them by my bed for about 12 hours. I am bedbiund so I need someone to pull off the speakers then put them back later. I do have a computer sound system a BIC America 12 inch sub next to my bed that will shake the room and piss off the neighbors behind my bed. So I am the PITA!
