Thank you for input. You are probably right.
Unless you want to use the 2405/077 there is not really too many JBL alternatives that runs flat beyond 20kHz. (I cannot fit 2404) I know you cannot really hear up there but I think that the overall "experience" get's more enjoyable if the top end is there. I have no real explanation to why but if I tune the XO’s to 16kHz, which is about as high as we can hear, the sound is different if the tweeter is in or out. It should not matter at that frequency, but it does regardless of filter type or slope (max 48db/oct in my system, no low pass on driver/horn). At least to my ears.
The Ti025 comes from the Ti10K which is rated at 300W (I think) with a cut off at 3Khz. With the above reasoning it should get about 45W RMS in such setup (15%). I will have a cut off at 12kHz or higher so the power is probably lower than my estimated 40W so I think (hope) I'm good.
This entire exercise is really driven by that I want to update my amps and the market seems to offer only very meaty monster amps with >7x150W (+30 Kg) or smaller units with 7-8x40W @ 8ohms or less. To get a 7x150-300W monster to rum my 2451/2332 above 1kHz and the Ti025k above 12kHz does seem like a little overkill…..
I need at least 7 separate amps for mains, rears and center. Sub's and lows amps are already in place (Crown @ 5x250W/Urei @ 2x600W).
I will probably by one of the small amps and do some measurements.
Comments?
