Larry: Great to hear that your show was a success. I too had another successful gig today with the Tyros & KP-100S alone, performing primarily jazz standards emulating a small trio setting (vocals/piano, drums, bass) for a faculty luncheon of about 30 professors at the Unviersity here, and both sound quality & volume level covered the room nicely while performing the song material they enjoy: Cole Porter, Gershwin, Jobim, etc.



As I mentioned on a separate thread, I recommend placing the the amp on an Ultimate Support 'Genesis 150' amp stand which imho better places the amp 6" off the floor and angled up approx 35 degrees. I found this (for some reason) improves the bass response. I've found (for me) that the expander set between 4 and 6 works (with vocals) for me. I also reduced the reverb setting on my Tyros and that seemed to clear up the earlier vocal problems I had with the Expander set at these settings.



Though turning up the bass knob will certainly add a (boomy) bass which can even rattle the windows, it's effect is not rich & deep, but more muds the mix. I believe this is limited by the size of the woofer (8") itself. My personal feeling about your idea of swapping out the woofers with another (better?) pair of 8" woofers is that it may not provide as much deep rich bass improvement as you might hope, because a lot of the problem has more do with the 8" size size itself. Another thing to consider is that switching out the speakers to slightly better sounding will increase the weight of the unit substantially because better sounding means utilizing a heavier magnet. For situations where you need a bit more bottom end, I'd might suggest a small subwoofer add on box instead. I use the 17 lb Tyros (TRS-MS01) subwoofer and it seems to do the trick. John Fisher (Motion Sound) advised me that they are looking into offering a subwoofer which will work optimally with the KP-100S, so you might want to contact him for a recommendation.

For smaller venues, the KP-100S alone (without a subwoofer) has met with pretty good results for both myself and the audience. I find it works especially well for exposed acoustic material: piano, bass & drums, and vocals. What I like most is the ease it is for gig transport & setup, and that the nature of the stereo enhanced amp allowing me to use it for both monitoring the mix & providing the main output to the audience as well. btw: I set the amp back about 4-5 feet a little to the right behind me. This way I don't recieve the full blast of the speakers, but still able to get enough sound for stereo effects monitoring. No problems with mic feedback either.




The JBL Eon 10 G2's wattage output totals 200 watts (125 to the woofer & 75 watts to the horn) so I'd expect that at 100 watts total output , that the KP-100S be putting out far less (1/2 ) volume. I believe at 100 watts, the KP-100S was only designed to handle small venues of up to 40 people, so I was pretty impressed & surprised you were able to play & sound good in a space large enough to accomodate 60 people. I myself will continue to take my 2 EV SxA100's (300 watts total per speaker) for the bigger events, and reserve the KP-100S for small jobs only. Unfortunately there (up to this point) is no one speaker system suitable for every job.



Interesting idea. I wonder just 'how much' time you'll save with the power cable & audio cable permanently attached to the amp. If it was a minute or two, this appears worth the effort, but saving only 10- 15 seconds is another story . Anyway, I look forward to your feedback after you have this setup and hope you'll post pics as well.

Larry, I've enjoyed reading your feedback & impressions, especially because it was 'you' who initially informed me about this new KP-100S model coming out quite some time back. It's beginning to feel like we're both new parents sharing expereinces and exchanging tips about our new arrival.
