Thoughts on this setup...

Here's what I'm thinking with regards to my TourX setup....

2 x 15"
2 x 18"
2 x EV Q99 Power Amp Plus One other Amp.
DBX 1231 EQ
DBX 3-Way Stereo Crossover

I know how to hook everything up to the crossover from there my thoughts are to go from the Mid/Highs to the tops and use the Sumed Sub out to the subs....

The question is am I better off running to Sub 1 and then daisy chain to the second thereby presenting a 4 ohm load to the amp and running the amp in Bridged mode or would it be better to run it in Parallel and feed each sub their own signal.

As a side topic I've never used an EQ of this magnatude nor a crossover so I'm a complete noob as it were to these two pieces of equipment. So be gentle.

There I fixed that for ya!
EQ To Crossover
3 pairs of outputs from crossover to 3 amps. Hi, Mids & Lows.

What happened to those awesome extremely powerful Bose sticks that can easily cover 1,000 people, which spread the sound evenly at the same DB level no matter where you are in the room?

Your subs are rated at 500 Watts RMS/1000 Watts Program/2000 Watts Peak
The Q99 is rated at 2800 Watts bridged mono at 4 Ohms.
I would daisy chain the subs and use the amp in bridged mono to have some headroom and real thump. If you use each channel individually you're going to be asking "Where the hell did the bass go????"

MIXER --> EQ, PROCESSING, ETC. --> CROSSOVER THEN IT'S MID/HIGH PASS TO AMP 1 AND SUMMED MONO TO AMP 2

One last thing when $$$$ is available try to buy a third amp (Backup)

Find your own damn system, Copycat!

Question for you.

I know it will probably sound better with the crossover. But the tour x tops and subs have their own built in crossovers. So couldn't you just do full out to the tops and full out to the subs and daisy chain the amps?

rob, as you know i run the same system and i recently changed the way i run it and its working great in all situations, karaoke 4 nights this week and then tonight i just got home from dj'ing a sorority ball at Longwood University and it sounded amazing. im running the same speakers as you, using an ev dc one crossover, with an ev q1212 for the subs and then an ev q99 for the highs. I highly recommend this setup

Rob..
Is there a way to bypass the internal x-over in the Tour-X??

9 outta 10 times i've seen...When you want more "control" you have to bypass
the internal x-overs...Otherwise your really not changing anything...

I'd talk to Ben about this..Before you buy anything.

Single Output for bass?

As I understand it... bass is omnidirectional, so you don't need to run it in stereo. I am NOT a sound engineer, but according to what I've heard/read, there's a greater chance of phase cancellation when you run bass in stereo.

So, if I understand everything right, you're better off going to a single bass output from the crossover and bridging the amp - unless the amp has the ability to duplicate the same signal to both channels so you can still run them at 8 Ohm?

The Q series can do this, just run the amps in Parallel mode. It takes the signal from input A and puts it to A & B. And you have separate volume controls of each channel on the amp as well.

This is what I plan on doing when I get my SB122's.

Rob,

I think you're on the right path in the way you want to run it, with the crossover and EQ. I personally run everything in stereo because it makes it easier on cable mgmt....ie, running to one side and then daisy-chaining back to the other is not my cup of tea. I run my tops with the Q99 and my subs with the CP3000S. Sounds fantastic!

This is the exact way to run that rig for DJ applications. Adding a processor/crossover just adds more clutter to an already simple system.It won't really do much more for the sound with all the processing.

1 amp for sub duty. 1 amp for the tops. Add a quality mixer like a Rane and your sound will be sweet.

Come on guys it was a joke!sqlaugh

Bridge the Sub amp as SVO stated and the Crossover is going to sum the sub frequencies anyway so they aren't stereo to begin with. Depending on the output section of the Amps and the inputs of the speakers you really don't need to daisy chain. Just run run one cable from the amp to one sub and another to the second sub. Nine times out of ten you are going to be (or should be) running the subs side by side anyway so the daisy chaining issue really isn't an issue as far as running the cables back across! However if the inputs to the speakers are 1/4" plugs then you should be concerned arcing on the connectors with the amp in bridged mode! If they are speakon or banana then this isn't an issue! If they are speakons then check to see if they are 2's or 4's if they are 4's you can use a 4 conductor cable to the sub and a jumper either to the second sub or to the main depending on your setup! Most decent amps using strictly speakon outputs also allow you to configure both outputs to bridged connection although Banana plug outputs are much easier to configure for multiple cables!

Cross the sub frequencies at 80 or 90 hertz since your mains are 15's! Use the EQ sparingly and you should have a decent setup!

Depending on the internal crossover on the mains it may be pretty easy to install a speakon 4 to set up for biamping the mains but if you want to biamp all the time just bypass the passive crossover completely It is just a matter of unpluging the wires and you can always go back inside and plug them back in if you decide you want to go back to the passive or install a switch and you have the best of both worlds with little effort!

There is that what you are looking for Jon?

To hit on a few other points!

1. Passive crossovers eat power.

2. Sub Passive corssovers and or bandpass boxes have a very muddy sound!

3. Properly setup bi, tri. and quad amping a system will do more for the sound than all the EQing and process you can ever find to try!

4. It will also allow much cleaner sound at a higher volume using less power than any passive setup can even start to think about!
