Had a few quick questions related to BA choice.
So I know of a manufacturers switching from sonion 38 + sonion 33 series ba drivers to sonion 38 + Knowles 31 series ba drivers for low/low-mid frequencies. They are keeping the rest of the high frequency range to 8 bellsing twfk ba drivers. So the only real change is the move from sonion 33 ba to Knowles 31 ba. What's the difference here, which one is actually better?
My next question is a separate question. I want to know which of the following configurations would cost more (a rough guesstimate since I don't know all the exact drivers used), assuming they use the same DD.
Configuration A:
2*Knowles RAD-33518 for high frequency 4*Sonion 2600 for mid frequency
1*10.2mm DD for bass
Configuration B:
2*Knowles twfk for ultra high frequency
2*sonion 2389 for mid-high frequency
2*sonion 37 series for mid-low frequency
1*10.2mm DD for bass
And a last bonus question since this one is the most subjective and depends on too many other variables, which of those two configurations do you guys think is best?
1st thing first. The right implementation is what matters and less about this exact ba versus that exact ba. Everything has to be taken into context to be compared and the way things are tuned as a whole package is what ultimately matters.
Assuming when you refer to Knowles 31 series maybe in your case those are equivalent to DTEC (which is kinda equivalent to sonion 33 series in term of vague fr coverage) Then there could be various reasons why those are in use instead of the sonion 33.
Maybe they found out that it has less of a 2nd peak that could help them achieve a better transition, or use a certain peak into their advantage, or or maybe slightly different 1st peak, or slightly different lower mids and bass behavior etc..
Maybe they needed that certain 31 series to work with the rest of the drivers since it offered a certain impedance characteristic, extracting the spl and behavior they needed for the fr range it covers.
Maybe they had issues with sonion supplies and found an alternative that suited them.
Maybe the size of the driver or spout placement worked for them better inside the shell.
Maybe it's slightly cheaper and offers a similar or good result.
There can be a lot of reasons to why they've switched to a different driver. But all these are just assumptions and it's difficult to evaluate how the change exactly works for them.
Regarding your 2nd question
the 1st option might end up cheaper but it's close and can depend on bulk qty
*maybe you meant swfk then the 2nd one should be more expensive depending on the swfk version
Last question
On paper one could think the 2nd option is better because it has more different drivers but who knows...implementation is what matters.
There are more complications with the 2nd config especially using a twfk and 2389 together which is prone to more difficulties, maybe you meant swfk there, then that's different and then I might be inclined to go for the 2nd one as having more potential
But again who knows
