8030A's + 7350 sub?

Youngling Posts: 8 Join Date: 3/3/15 Recent Posts
I have a pair of 8030A's and am considering adding a sub for some sound design work that I do. Would I be able to use them in conjunction with the 7350 sub? I'm assuming I'll need GLM to do my gain adjustments and crossover settings... Is that right?

Eventually I am planning to upgrade my 8030's to the 8320/8330's as well but for budgetary reasons I need to do things one step at a time.

Thanks in advance!

Hi,

Yes, you can use those together in the same system. 7350 needs to be controlled and calibrated with the GLM but obviously 8030s need to be operated with their own controls (DIP switches). Once you'll upgrade to DSP series speakers, you can control and calibrate the whole system with the GLM.

Do you have any recommendations for setting the phase of the 7350 in my situation?

I adapted the coarse adjustment method from the 7050B manual to GLM which helped tremendously but as GLM offers add'l phase settings, is there more fine tuning I can do?

I don't have any test equipment other than an SPL meter unfortunately.

Thanks.

Hi,

Typically it is difficult to find any audible improvement over the typical method and 0/90/180/270 degree options. Which setting do you have at the moment? You can use your SPL meter to find the best option by playing an 85 Hz tone (not too loud) and monitoring the SPL reading while you are adjusting the phase setting. Ideally the best phase matching should provide you the highest SPL at the crossover.

Thanks for the reply. Your answer confirmed my findings. I have my phase set to -180 degrees which measured the loudest on my SPL meter.

Just wanted to confirm before I get knee deep into mixing.

Thank you!
