#Nightwish signal path guitar upgrade#

Fortunately I found in the schematics a place were I can add a filter to smoothen that as well. Although many people would say that that is not a bigger issue I do not like that because with many actual recordings, especially pop and rock, or also modern DACs, the sound can get a bit stressy. Also her one sees that the bump at around 4 - 7kHz is smoother and if the picture would not be cropped one will noticed the bit stronger emphasis over 10 kHz. The red curve shows the change with the tweeter flush mounted. I have added in blue the response as it was before without the flush mount. With this change I have got the following overall frequency response of my MFB586. What I found interesting is that also the slight rising over 10kHz got a bit more emphasized. If one looks to the frequency response that results after a flush mounted tweeter ( red curve ) one will recognize the the reproduction is much more smoother and uniform.

It causes per example harshness in the ess reproduction. Unfortunately in between the frequency response gets higher and that is a critical range in which the human ear is very sensitive. One can see that the response is pretty 'bumpy' having larger dips of up to 4dB e.g in the area around 2 - 4 Khz or in the range of 6 - 8 kHz. The frequency response in blue is the original state, which actually does not change very much if one puts the grills on the front. I know that does not look very nice but the result are pretty clear and for me right now more important as updating the electronics and as one can see from the measurements there are some significant improvements. For doing so I have placed paperboard around the tweeter leading to a flush mount as can been seen in the next picture.

This is the next point I am wanted to address, before doing any upgrade to the filters electronic components. Not doing so causes a lot of irregularities in the frequency response. the tweeters have not been flush mount in the front baffle. I am with you, a revision of the electronics makes a lot of sense especially if the devices have an age like the components we are speaking about.ДЄnyhow please understand that I also look to my pair of MFB586 from a developers ponit of view and therefore I try to understand or figure out what the development has tried to adressДЄnd from that point of view I really wounder why e.g. It will make you wonder what this kind of treatment will do to a pair of 587вЂ™s but that is something for you to find out. They donвЂ™t sound like 30-year old speakers at all!

The soundfield is deeper, wider and more transparant. My pair 586 and 587 have Nichicon MUSE Fine Gold in the signal path and BC Vishay 021 ASM axialвЂ™s in the power supply (but any A-brand, low ESR wil do just fine there, especially types that are intended for switched mode PS are a great improvement).
