will the crossover be in the amp case?

Yup. My bedroom system with integrated F5T's inside.

for bedroom everything needs to be sensitive , including spks and amp

I can think of at least 3 things need to be Turbo , before amp

It seems i am in trouble then.

 

[Zen Mod]

you can start with Turbo Light

Hi,

I am looking for an electronic crossover to do the following:

low pass and high pass on midrange (330Hz and 2Khz)
high pass on tweeter (2Khz)

6db/oct slopes

I will need TWO B4s, correct? Will the sound quality degrade going through two B4's?

Thanks,
Herman

Yes, two would be necessary for this type of crossover. Your probably would want one for the left channel, one for the right.

Nelson or Jon,
I am staring at the B4 internals, working out my version, and i realize i dont see a psu.

 

[Zen Mod]

Small switching power supply on the cord.

2x B4 had been perfect for my full active 3-way F5 powered system that is comming.

I hope soon there will be schematics available and maybe someone will make it modular 🙂

B4's

There is still no information on a new run of B4's. They do not appear to be high on the list of projects.

B5's are still available. This is the version for full range drivers in an open baffle speaker. (can be used with a slot loaded woofer if you like).

B4's are coming on slow boat.

Nelson,
Would you be willing to divulge the reason for the change?

I guess a slow boat is better than no boat. I guess will have to survive on my single B4 for now before expanding, but it still is an amazing piece. O Captain! My Captain!
