Members I stink at bass Posted December 4, 2011 Members Share Posted December 4, 2011 Well, I am DEFINITELY not a sound engineer, so having all of the work done for me is really nice. I don't have to worry about cabinet efficiency, how much amp power I need to match the speaker, additional processing, etc.. I just plug and play. At practice the other I noticed that the singer was standing directly in front of the speaker with ZERO feedback. Then I thought about it, I haven't experienced ANY feedback issues since I started using the RCF speakers. Like I said, all of the work is done for you. They are ALMOST idiot proof. Exactly what I need. Link to comment Share on other sites More sharing options...

You are correct that almost all the work is done for you ... but it really has nothing to do with feedback Link to comment Share on other sites More sharing options...
Members Reson8tor Posted December 5, 2011 Members Share Posted December 5, 2011 I'm going to slightly disagree with Dboomer about powered speakers and feedback. Powered speakers with internal DSP tuning are more likely to have a flatter, less peaky frequency response than an equivalent passive speaker. I think it's easier to avoid feedback with a flatter-response system, which is just common sense. You don't want to be superimposing frequency spikes from a mic on top of a speaker's peaky response curve. It's easier to get a little closer to that flat-response goal with a powered speaker, at least at the lower end of the PA gear spectrum where I operate. All the other usual factors in feedback control still apply, like proper mic-to-speaker distance and angles, control of stage volume, etc. It's not a magic bullet, which is why I still have a Sabine FBX2400 in my small powered speaker rig.

Members agedhorse Posted December 5, 2011 Members Share Posted December 5, 2011 Reson8tor's comments are IMO valid, especially at the middle to entry level. Link to comment Share on other sites More sharing options...
Members I stink at bass Posted December 5, 2011 Author Members Share Posted December 5, 2011 Like I said, I know nothing about sound engineering. However, I DO know that when we had the passive Peavey's we used to get feedback if we went ANYWHERE near the front of the speaker, especially at performance level. Now the singer can move all over the place, even at performance level, and we have yet to experience ANY feedback. Why that is, I really don't care. It just gives me one less thing to worry about.

Members abzurd Posted December 5, 2011 Members Share Posted December 5, 2011 While it's an oversimplification, it's certainly possible that your gain before feedback is increased simply by changing speakers. The flatter response, at least in the feedback areas you were experiencing, could help you get a few more dB's. The overall response could be less peaky, especially if you were using a speaker with a piezo for the high end. Piezo's generally have horribly uneven response and are prone to feedback without EQ, but then again, cheap compression drivers aren't very flat either. It could also be that the speaker sounds better (less woofy or more silibance) so you don't need to get it as loud. It could also be the coverage pattern difference of the horn or the cabinet angle related to the microphone. Link to comment Share on other sites More sharing options...
Members I stink at bass Posted December 5, 2011 Author Members Share Posted December 5, 2011 Or all of the above! Link to comment Share on other sites More sharing options...
Members I stink at bass Posted December 6, 2011 Author Members Share Posted December 6, 2011 Just got through messing around with the new 312's and YEAH.............No feedback with those either. Who loves RCF powered speakers? Megabass, that's who! Link to comment Share on other sites More sharing options...
Members dboomer Posted December 6, 2011 Members Share Posted December 6, 2011 I'm going to slightly disagree with Dboomer about powered speakers and feedback. Ahh ... but you've changed the statement. The OP's experience is not related to "how" the speaker is powered ... there is no "ZERO feedback" speaker. Feedback is not related to how level is created only to that level is created. Link to comment Share on other sites More sharing options...
Members Rbts Posted December 7, 2011 Members Share Posted December 7, 2011 I also know little and do little but when I WAS using my powered speakers a couple of weeks ago the singer for this act did the same thing and took his mic right out in front of my powered yorkville speakers and I cringed - but joyfully - there was no feedback. I felt great about that. The mic was a beta 58 so maybe the mic has good GBF #s too? Link to comment Share on other sites More sharing options...

Same results, so I don't thing that it is the mic. Link to comment Share on other sites More sharing options...
