rgds, sreten.

A very good suggestion i will try this.
i started out whit a 60L closed because i had this lying around from a previous prosject.
I must say i sounds very good already real nice vokal and nice bass respons
it is a real promising driver in the right enclosure.
it has a sweet sound that makes me wanna listen to my entire record collection

I feel there is many roads to rome, an i am not shure where i end up.
But i am shure it's gonna sound great after what i have heard tonight.

Eariler today i got my hands on a 92L net volum bassreflex enclosure
tuned to 32hz. I know it should be 28hz but it has a built in port so it's a bit harder to change it.
I will come back with a report as soon as i have listened to it for a while.
And write some word on the differences between the two enclosures

Hi,

32Hz is very ballpark and 28Hz was only a personal suggestion.

FWIW you can experimentally detune ports by lining the port walls
with thin porous foam, I do (well did) this a lot for room matching.

rgds, sreten.

Hi sreten,

Can you explain the room matching? Is it to avoid exacerbating a room mode? Is there a way (afterwards) to confirm / validate the results, e.g. with test tones perhaps?
