Re: Danley SH96HO
Not nearly as off-putting as the "impossible to state" NO numbers answer. In that case, accuracy is completely useless.
I agree. If they graphed the magnitude and phase response of the drivers in each passband that would answer my question. But the published graphs do not.
I am not trying to be rude in the following answer-but please try to understand.
What you are asking is A LOT of work, that will take a good bit of time. So what is in it for Danley?
What you are asking for is not exactly as "simple" as you say.
For example-You are asking that we "simply grab some traces"
Let's look at what that actually entails and why it is not as "simple" as that.
SURE-we could that with a little bit of work-but the answer would not be correct-but maybe that is what you are looking for-just something?
For example. This has a passive crossover between the mids and highs. All the components in a passive crossover affect everything else. Sometimes quite a bit-some times not so much.
For example-Let's just say we disconnect the HF driver and measure the mids. How do you suggest we deal with the "unterminated" crossover section on the HF? That loading can affect the response of the mid driver. So do you want us to remove the circuit board, and then unsolder the input to the HF crossover? That takes additional time.
How do you plan on dealing with the "unterminated" HF driver? Just having a diaphragm "hanging out there" is going to affect the mid range response.
If we short out the HF driver-that will provide some sort of "terminantion", but not that actually provided by the HF crossover.
And those measurements would be for the "acoustical crossover" of individual components ONLY. Once you have BOTH drivers working, the result can be different (as Rich says) due to the PHASE response of the drivers.
But that makes it harder to see any sort of "acoustical" crossover-if done properly.
And the same thing applies when trying to measure the HF response.
To get the ELECTRICAL response of the crossover is a little bit easier.
We can simply take the cabinet apart, (fortunately both the mid and HF drivers in the case are sealed-so having the back removed is no big deal), dual a dual transfer function of each freq band, and produce a report for you. But this takes some time.
This will give you some graphs-but no ANSWERS. As you have to combine all of the above to come to some sort "answer".
But who pays for all of this information gathering? and for what purpose?
We don't need to do this for our needs. I personally don't have the time on my own to do it.
You could put a request in to Danley for the information. But unless you are willing to pay for the time-I could do it "when I get a chance". But that could a couple of years or more-if things slow down a lot.
Again-I am not trying to be rude-just stating some of the realities.
