[QUOTE="OlogyAudio, post: 1052219, member: 562170"] He did have a valid point though that the L18 isn’t the exact driver that the rainbow platinum set uses though -- and they made adjustments to is to it is somewhere between the quality of the L series and Excel more than likely but to prove anything definitively I would have to get the real Plat driver measured, which is something I'm not going to be doing for some time... I mean think about how many sets I would have to sell in order to be able to buy the Rainbow Platinum set... it just isn't practical lol... I think it is obvious that I'm legit, not trying to screw people over, and that my claims are subjective -- but at least there is some sort of technical data that puts my claims into the proper light and makes it apparent that they are indeed reasonable claims... The biggest tradeoff I made in my design with the RS drivers is the 1.8khz xover point… with an xover this low, even though it is 4th order there is still a substantial amount of power that is going to the tweeter… at *very* high volumes with program material such as metal – or some intense rock like Static X the tweeter can start to get a bit harsh… If this is your listening preference I would have to recommend a 3 way or a soft dome tweeter… if you don’t want to sacrifice detail you will end up having to get a high end seas Excel tweeter which eats a few bucks… Alternatively I am working on a 2 way with the Seas TBFC/TDFC (almost interchangeable, very few changes needed) with a seas midrange… playing with both the MP and MCA midranges… Granted these drivers want a 2nd order high pass at about 150hz or so -- 4th order is fine at 120hz or so with the MCA, 100hz or so with the MP units... These are the likely candidates for the XXX 3 way... They would also be suitable for a 3 way with the Dayton 8” RS woofer… for the more value oriented… This would eliminate the slight harshness at very high SPL, maintain the awesome midrange accuracy… not to mention you would get an even more authoritative midbass.
