Going from 2x UCS1's to a SRX728s
« on: October 15, 2009, 07:13:58 am »

After a few shows, I believe I've pushed my two UCS1's to its limit... and perhaps that it's even the wrong sub for the music I play.

Background:  I usually provide the sound for the second dance room (no bigger than 30 feet by 30 feet MAX, usually smaller) for underground raves throughout San Francisco.

An event we threw in July.
Rig:  4x Mackie Fussion 3000's for mains.  8x Mackie Fussion 1800's for bass, 2x Mackie SRM450's for monitors, and hundreds of hippy ravers on god knows what sort of drugs.

I'm finding that the UCS1's sound overly "boomy" and lack that 30hz bass that a lot of electronic music contain.  The Mackie Fussions actually kept up quite well.

Would I get anything from getting rid of my 2 UCS1's and getting a JBL SRX728s?  I'm running a Yamaha P5000s, which puts out 2,600 watts bridged at 4 ohms.

Here's an example of the music we usually play at levels that make your chest shake, kill small babies, and make satan cry from 8pm-4am:     http://www.imeem.com/psytrancer/music/fMBvAtkS/mindcore-ador ation-lost-found-remix/ (fast forward to 1 minute).

It was 3 days in a forest.

Night Time:http://www.youtube.com/watch?v=8mSONyRRB6c

This event was the DEFINITION of system abuse.  We ran our sound system full volume CONTINUOUSLY for 48 hours.
Similar indoor event last year: http://www.youtube.com/watch?v=LsXi0lrmN9w

Felix,
I don't think a single 728 is going to be much of an improvement.  You really just need more subs.  That style of music requires a significantly higher ratio of subs to tops than most genres.

But from what you heard in the sample, would switching from folded horn to bass reflex benefit me, in your opinion?

Possibly a little.  But not worth making that move unless you intend to expand into more 728's in the future.

You might also consider adding a Waves Maxxbass processor (ie 102 or 107) to add a little bit of increased perception of bass.

It's not surprising that the UCS1's don't have much output @ 30 Hz.

Just a side note: You can't run a Yamaha P5000S bridged into 4 ohms. Bridged it's only designed to play into 8 ohms or higher (and will only do so reliably).

  So you are comparing, 8x Mackie Fussion 1800's to 2x UCS1's?

Mackie Fussion 3000 are very loud speakers and i think you will need at least two 728's per side but properly amplified with around 3000W per cabinet in order to have good results.
