Hello everyone the more I listen to the Marty Cubes the better I like them. Now the question the urge to build has struck again but due to space limitations I am looking for something smaller to use for midbass and nearfield ( from what others have wrote that seems pretty neat ) I am not interested in something large due to the space I have in fact I was hoping to use a couple of 12's in a smaller box. I was also thinking for power I would use the nu1000 or the DSP version but that leads to another question. Most of the flatpacks I have seen in PE or DIYSG are sealed and from what I remember it is not a very good idea to have both ported and sealed in the same room? Like I said I am not looking for anything that gets down low but I am looking for a good strong midbass. All of my separates are 2-way with the mid range of 6.5". I thought with a good midbass driver it could bridge the gap between the 2 18's and the bookshelf speakers. Any ideas?
