Re: Yorkville PSA1?
I have used these on two shows both with the same act, a top 40 DJ replacement cover band. In both instances I used one per side with the matching subs an pole mounts set to the greatest height. The larger of the two events was a wedding in an 80'x40' converted church hall, audience size was approximately 300.
I measured the on-axis response of the speakers using Smaart and an Earthworks M30. In the "single speaker" setting, the speakers required a 4dB cut at about 450Hz with a Q of 0.8 and a -3dB cut at 10kHz with a Q of 2.8 to give me a flat amplitude trace. Once this was done, the speakers performed extremely well. Two notes: First, I found the directivity of the HF element to be accurate to the published specifications - it took me some time to position the speakers correctly to cover my audience area, and the results were very good. Second, matching one of the PSA1S per PSA1 did not give me the output I was hoping for, however I was not able to deploy the subs in a cluster.
I noticed the limiter light engaging during the DJ portion of the event, and although it was not audible to me, I did not push the system past that point. With matched input gain settings on the tops and subs, the system has a peak or "haystack" of +14dB at 80Hz relative to the crossover point (100Hz.) I reduced the input gain on the subs substantially because I prefer mixing on a relatively neutral system.
I would like to do a side by side comparison between these, the JBL VRX932LAPs, Mackie HDAs and QSC KLA12s. Unlikely to ever get the chance though.
