JBL sound system multi surround!

Now there’s term I like to call “crazy bass” that hits the ear in way that you kinder flitch to one side quickly this was more recognized when I saw Titanic at the local ABC and via the -auditoriums JBL 4675-A screen array. When “Jack and Fabrizio” are running though the crowded docklands the bass rhythm was tapping my ear drum with pleasurable and yet pleasing situation that was kind of ticklish.

Now try that one at home but you’ll need matching fronts and a little phasing of one of the channels left and right to achieve this. The music is one the left and right fronts with subtle instatement on the split-surrounds the centre channel carries dialogue and effects during this sequence.

The first bass note starts around here with slow rhythm that picks up the beat in the next shot it taps the ear somewhere between the 40Hz and 60Hz region.

The crossover is set for Linkwitz-Riley 24db LF 50Hz to 1KHz – HF 24db 1KHz to 16.1 KHz 80Hz +7.0db Q 1.0 for the LF LCR channels.

A closer view of my little JBL Control 5 and for the first time they sound a lot better this way without the harshness of brittle sound thou they have been quite beneficial for the past 16 years, but now its time for active crossover active is the way to go its cleaner and its got far more potential.

...
Catwomen was the first film to be tested with the Behringer DCX2496 loudspeaker management system. I was astonished at how the hash sound disappeared into the JBL Control 5 thus leaving it with cleaner more dynamic lower and higher range, meow.

I have one of those older model Radio Shack SPL meters myself; I also have the newer mode.

Yeah its been dropped lord knows how many times and keeps on giving me good readings for a 10 year old SPL metre. It was sold by (TANDY) here in the UK and (TANDY) packed up here around mid 1990’s the only thing close to a Tandy store is (MAPLIN Electronics) I just re-soldered the wires on the VU metre last week an its fine.

Oh well I’m back and I’m tired after humping that huge monolith of 2001 odyssey JBL 4645 sub onto those breezeblocks, well it was easy the cardboard made it slide onto them and its kinder added a slight impact with X-Men II The Last Stand when Jean uses her powers to suspend objects until it all came down to thundering SLAM!

I believe the frequency response is down to 25Hz on X-Men II when that house slams into the ground as well as most part of film. It hit at 112dbc in the middle and that was more than enough comfortable without being overwhelming.

At the moment I’ve got summer hit from 1999 The Mummy playing chapter 5 when “Rick” busts in to save “Evelyn” his voice his heard from the left sidewall surround array and partly the front its then accompanied by some crazy LFE.1 pounding on my body.
