Soffit mounting Genelec 8040
Posted: Thu Jan 24, 2008 5:53 am
Hallo everyone,
In The ''Soffit mounting of Genelec 8050?'' threat Knightfly is not mentioning the opening at the front of the bazel which Genelec's mount box which I thing must be very important for the LF of the speaker.http://www.genelec.com/documents/other/ ... t_kits.pdf
I have talked with the Genelec's support and they told me that:
a) The 8040A has the opening of the reflex port in the back and for a proper operation of the port the air pulsated in the port has to be radiated inside the room. So, that the rear opening has to be channeled to the front part of the speaker or more precisely inside the room. If this is not happening, then I will have serious compromise in the LF response of the speaker.
So is the size of this opening maters? or if i place the speaker in the box and make a bazel to fit the speaker's front will it be ok? Any guests on how big this opening might be for a proper LF response of the 8040A
He also said that:
b) technically the speaker does not need to be in that box - there should just be a way for the air coming out of the vent (which is not warm at all) to be radiated inside the room. Of course the cavity behing the speaker and the opening inside the room are all critical for a proper LF response. This is why Genelec offer a simple kit that will make sure you have the best out of your 8040A in the whole frequency spectrum. Yes but it's to much 650€.
So, How can I construct the soffits to make the air from the back of the speaker to be radiated in the room? Do i need to let an opening on the bottom back of the box and also in the top and bottom of the soffit?
Also, the other think is, that in the Genelec's kit you have to take off the rubber base of the speaker and skrew it to the iron base of the soffit box kit. Would it be the same if i leave it with the rubber base, place it in the soffit box with its rubber base? Any thoughts on that? I would like to be more sure about which option is better before i attempt it.
Thanks in advance
steve
