Yet another one of these "4345" threads. I'm reposting this because I was asked to.
I decided to whip up a pair of DIY 4345's this past spring. I could post a bunch of reasons along with a ton of detail but I really need to get back to more pressing tasks at hand so I'll just post the pictures I happened to take at various points.
I suppose it would have been nice to do a full photoshoot of the whole process but my passions lay elsewhere during the six month period and I just wanted them done so these are the pictures I ended up with. I didn't even take pictures of the networks or the back with the access panel open but I have to take these apart in a few weeks so I'll take those pictures then.
The original components were going to be:
2245H
2122H
2445J/2311/L94 (aquaplased)
2405
Charge-coupled, bi-amp only 3144/3145 equivalent networks
And they ended up being:
2245H
2123H
2445J/2311/L94 with D8R2452H-SL diaphragms
2405H
Charge-coupled, bi-amp only 4344 Mk II networks that really should be optimized for the 2445/D8R2452H-SL combo.
4344 Mk II network
All the components are fresh with brand new recones and diaphragms.
I could be mistaken since I can't compare them directly but I think the tricked out 4355's with charge coupled equivalent networks sound a wee bit better. And that's very probably because the 4344 Mk II network is optimized for the 1.75-inch compression driver which has a wee bit less bottom end and a wee bit more top end than the 4-inch compression driver. In other words, "tilt".
In any case, I'll be moving on to the 4345 equivalent networks with the 2122H's and 2421B's as well as 2445J's in a few weeks after I get the rest of the 4355 networks out the door as promised. I'm extremely pleased with the tricked out 4355's but that's another thread I suppose.
