Speaker Tunings B52 and peavey qsc amps

rolo95

Hi
i know that curently DBX only post tables for
JBL EAW and some other speakers and
only crown amps....

but since the PA is the most afordable of your dirve racks products
and are budget oriented....
like me... i have peavey and qsc amps...
and B52 speakers...

how do i can get the tunings for my b52 speakers
i have the folded horn 18\" sub b52 ( like the cerwin vega L36 )
and the b52 2 15\" mids and 2\" compression driver highs speaker
like the peavey sp4 or jbl 4733....

( anyway i have replaced the high drivers with peaveys 44xt.. as they where blown before the i had the driverack )
hope this helps----
get custom speaker tuning that
where not listed on the factory defaults...

ROlo...

So I assume you are runnung three way? Since you switched to the 44XT's the Xovers iin the SP's would be very miss-matched... There really isn't all the info I would need to make a complete recommendation. You would need to give me amp models and sub models for correct settings... The fact you modified the SP's makes any specifications useless...

Reguardless you have to enter the info into the DRPA manually anyway... so get me all the info tyou can and I'll try and help

All right... fast and dirty:
Note: this is a \"starting point..

1.HPF (lowest point the sub will be allowed to go) for the sub... BW18 @ 40-45 hz deending on the power you have, if you have at least 2X the RMS power you could go lower...

2. Sub, LPF (highest frequency the sub will be allowed to go), 100 hz L/R24

3.HPF, Lo mid, 100 hz L/R24
LPF, Lo mid, 1200 hz L/R24

4. HPF, Hi frequency device 1200 hz L/R24
LPF. OUT ...this means we are allowing the horn tweeter to reproduce whatever it can in the extreme hf region...

As for alignment delay:
1. measure the distance from the bottom of the cone on the mid woofer to the diaphram on the horn....... probably less than 4 inches, since the horn lense is deeper than the woofer... you would delay the mid woofer till the horn can travel the xtra 4\" of distance

2. the sub is probably about an 8' delay so the delay would have to be applied to the mid and horn... and the mid delay added to the subs...
Now if you have the DRPA forget it... you don't have enough delay, and the difference is subtle... but if possible can really add to the cohrence of the system...

Use an all custom set up in the Wizard (as you have?) (I'd go 2X5 and run the subs mono and put them together on whichever side. if there is a boundary all I would go tho that side unless you need to set up anywhere around 3.6 feet from any boundary (up off the floor , from the back wall, from a sid e wall)...avoid this dimention like the PLAGUE!

Read the tutorials section... this info and more is there...here...
