Default And so it begins. Fostex FE166En + BiB

These arrived today.

My BiB plan is to build a hybrid BiB with the front, back, baffle, and bottom of MDF and the sides with pressed oak plywood.

I'll try to keep a photo log going here.

N4BBQ,

Why MDF? BiB is a big cabinet and the extra stifness plywood will give will come in handy. Also MDF is heavier, and these boxes can be pretty heavy (I built a BiB with FE166EN last year).

You're spot on about it being heavy. I donno. I guess the price got me. Our local Home Depot had some nice 3/4 on sale at $19/4x8 sheet so I bought two sheets of that, but I want a nice wood side, so I decided to use the Oak plywood for the sides. I plan to finish the front black and that should make for a nice looking speaker.

I won't have to worry about anyone rushing in and stealing them (unless they are a weight-lifter).

Are you enjoying your build? What amp are you using with them?

N4BBQ,

I had built the BiBs for a friend. The speakers were at my place for some time, and I was using a Miniwatt N3 and another El34 single ended amp with it. Both were a good match with the Fostex drivers.

The BiBs were very enjoyable to listen to - my first brush with full-range speakers in fact. Since I liked them went on to quite a few other builds.

What amp do you have/plan to use?

Very good. I'm sure the same will happen to me (on to other builds).

I just finished a single-ended 6N3C (6L6) amp.

The speakers I have now are old Infinity RS-6000s (but the woofers had been removed and replaced with some JBLs of some sort), so I'm looking forward to the Fostex build to see what sort of a difference there will be.

I will. I've been reading and thumbing through build pictures.

What is the opinion of using dampening material anywhere in the cabinet?

12mm quality plywood would give a better result (and i wouldn't use less then 18mm (~same as 1 1/4" MDF) in a build this big (unless very well braced)

Thanks for the tip.

BUT, I've already cut all the stuff...but looking at the bright side of that, there's always the next BiB made with all plywood and possibly a different speaker.

A few parts that are cut & dry waiting on a few other parts to dry.

Question : How has others routed their speaker cable inside the cabinet?
