there is a possibility that the old speaker damaged the output transistors on the amp. i have seen that many times. i have a lot of experience with the Daytons, and the only one worth using is the Ultimax. like the eD speakers, they can cause a slow death to any amp once the voice coils are overheated, even if they ohm out correctly.
but then again, 200 watts RMS is not much. depending on the frequencies, you may be using all the amp has.
So Dave, there is a possibility that the amp is at its limit and would clip? I figured the output would just stop getting louder at its limit. Its a shame because i can definitely tell the infinity driver sounds much better, but am concerned to push it if the amp is just going to clip on me.
That being said, my train of thought is telling me two things given the input from dave and laugs.
1.The amp is degraded to the point that it will clip during scenes that utilize low intense LFE.
2. The amp is possibly underpowered and is clipping somehow?
I was hoping that with this new driver i could really push this sub hard but for some reason that is not the case.
If soft clipping you mean a slight clacking then that is exactly what I heard. The old dayton would do that as well but would sound a lot worse and do it more frequently. I tried setting the avr trim down and bringing the amp gain higher and that seems to help.
That opening scene to gravity shook my whole house way more than the dayton, but when i brought the avr trim up i observed the amp light go from green to orange at the exact point of the clacking sound.
In both of your opinions, what options do i have to remedy this situation cost effectively? Im already thinking about building a sealed 15" ultimax.
Thanks in advance and of course thumbs up!Edited by Patrick1229 - 2/26/14 at 4:58pm
