A simple but yet effective sub bass improvement!

Gold Member Username: Thx_3417Bournemouth ... Post Number: 4012 Registered: May-05 | Take a few simple (breezeblocks) and with some plastic of other placed underneath them prevent them from making a mess then place the sub bass on them. If the sub has feet its okay as this will not scratch the surface. If it doesn't have feet place some carpet on them followed by the sub bass.  This was one of the things I tired out since late of last week and thou it was kinder successful at reducing vibrations it wasn't near enough when I got around to playing Return of the Jedi yesterday afternoon.  Chapter 13 The Emperors Arrival all the deep tympani bass was kinder lost due to the placement as I had only played a few films since and I guess some of them didn't have bass between 20 and 40Hz that was deep enough. So after use the SW-Re-mix function on the Kenwood KR-F9050D THX select and sent the screen channel bass to the JBL 4645 where it sounded outstanding with lots of drama in chapter 13 when the Emperor arrives at the new Death Star. Now all I had to do was re-position it which took around 8 minutes played the same scene over again and wow that was better and no vibration that is originally within 2" from the floor surface this produced enormous rattling problems with the floorboards where I forced to reduce the volume be many db, and as you guessed it this would reduce the impact emotional drama of the mix. When Han Solo gets punched after carelessly steeping on a twig SNAP! The stormtrooper gives him one heck of smack that felt better than before yes a few (breezeblocks) can make a bit of difference.   |

I got some red brick ones and put them up under. You hardly notice except the sub is higher. Like the ones you would see on a nice garden patio. |
