Just admiring Challenger604's beautiful 4355 project over at the "4355 Monitor plans" thread I thought it's time to give you a glimpse at my 4355 version. It is, of course, not finished yet (the cabinet is lacking surface treatment) but this is going to happen soon.
The cabinets are made of 25/20 mm beech ply, which is a really great material in terms of strength. But building such a beast from stuff that hard and heavy isn't exactly a piece of cake. But birch ply or MDF really can't compete with this, so I am finally happy after a lot of bruises and scratches .
I've made only minor changes to the original plans, for example there is now a support for the 2441 that really deserves the name and not that lousy sheet metal angle supporting the horn, not the driver.
Sourcing the drivers wasn't that easy here in Germany and so I ended up buying 2202, 2441, and 2405 in the US which didn't make things exactly cheaper, but everything turned out to be decent quality stuff, so I am fine with that.
The woofers began their lives as E140 and got freshly reconed to 2235H. At least that's what I thought, In fact the additional mass rings got folded, so I ended up with 2234H with a slightly stronger motor (due to the stronger magnetisation of the E140 magnets). That didn't turn out to be a real problem. With the original 28 Hz cabinet alignment, the system is tuned a little bit too low, which can be easily corrected with a bass equalizer.
