3khz is way too low, and risky with such a pricey driver.
8khz to 12khz would be better, but it depends on the horn you are using.
You could be right about this.You would be better served with a real subwoofer instead of the 1601
I am not so sure about this idea. Having the TL-1102 as the mid-bass, I believe, has great advantages. Not only I do not take the TD-4001 and the TL-1601 to the edge (where they do not perform very well), but I also have the volume adjustment ability for the lower half of the mid-range. Therefore, I can fine tune the sound. For example, if I add more volume on the mid-bass driver, I will get a thicker sound; It will feels like the singer is heavier and the sound of the instruments have more weight. The key is this can be achieved without affecting the bass. I did not realize this benefit until my system was set up.maybe get rid of the 1102 and let the 1601 meet the 4001 if you have a big enough horn
Slow or fast has no real meaning when speaking about drivers, specially subwoofers.
Perhaps we are referring to different things.
I am referring to the speed of cone movement of woofers and subwoofers. How fast the cone can move in/out and retracts to its normal position. But let me know if your statement still holds true.
Does anyone else have knowledge about this?
yesHow big the cabinet for the TL-1102 needs to be in order for it to play down to 60Hz-80Hz? Does the cabinet need to be ported?
1000W per channel would not be overkillWhat kind of amplifier do you recommend for the JBL SUB1500?
I assume you are referring to class D solid state.1000W per channel would not be overkill
woofers and LF need WATTS! lots of them! Brutal Pro amps are ideal for this task.
