I actually had a chance to demo these today. I came in with my mind set on the 16's with Freqphase but wanted to hear the other models. I was steered towards the JH13's by the rep since I was not a bass player or drummer or using them to listen to movies. They sounded great, ok amazing. Very transparent, clear, and natural. The bass response was very balanced in my opinion and they did sound very transparent. Then I went to the JH16's and man, they sounded even better but there was a significant difference in the bass response. I loved it, but my concern is that it could be too much after a few songs. I'll be using these live with a band at my church and also doing some other shows. If I had a monitor engineer I wouldn't hesitate to get the 16's because I know they would be able to keep the low end in check. My concern is that since I'll be getting a board feed and won't have much control over EQ that if there were issues in the low end that it could take over my mix and make things sound muddy. Now I'm sitting here trying to decide...for the extra $50 you get 2 additional drivers and the 16's did feel more "in your face'' than the 13's. After reading these posts, I'm leaning toward the 16's again just because I'd rather have the additional drivers and not use them then to need additional drivers and not have them! I'm also leaning towards the 16's because of what Jerry says in the video posted in this thread about the extra input sensitivity since I'll be primarily using these live...I'll post the video again at the end of this post. Jerry has talked me into the 16's again
What really surprised me was how good the JH5's sounded...blew me away that they sounded so much better than the triple driver customs I have now. The bottom line is I don't think you cannot go wrong with either purchase. If you're in and environment that you have control over the low end and can make adjustments if there are issues, don't hesitate to go with the 16's. If not, the bass response on the 13's was fantastic and if I would've never listened to the 16's I would have never known it could be better. Basically, what everyone has said is true...13's more neutral...accurate...16's more low end at 50hz, more input sensitivity...both sound incredible.
