Depends on your SPL requirements..The room size where I took demo of Rythmik was around 12 ft x 15 ft x 10 ft. And it was not acoustically treated.
whereas REL HT1508 I auditioned at an exhibition where they had created a room of size 15ft x 15ft. Since it was dark I could not see if the room was acoustically treated.
I would be lying if I would say that I didn’t go for Rythmik sub with much higher expectations and this must have added to my feeling of disappointment.Now do you think F12SE should be able to fill space of above size ?
Further I can’t say about other FM’s but I find it very ironic that you are commenting about REL subs just by reading online reviews. I suggest you to atleast try listening to any of the REL subs before writing them off so arrogantly.
Over and out. Won’t be commenting on this topic anymore.
