Are there additional details on the Fast 8 SLOB build somewhere? I actually have a pair of Fast 8s collecting dust. Maybe this would be a good build to utilize them. One reason they are collecting dust is I've never been impressed with their high end. If this is an OB project that includes a tweeter to help the highs, I'd be very interested. The 8 sounds great except for upper highs. And no... it isn't my hearing. My wife with bat ears commented on that the moment she first sat in front of them and my daughter (who inherited her ears from mom) had exactly the same reaction.

Try this thread-

Papa's slot loaded open baffle version#2

Attached is a rough build plan for the frame.

No reason why you could not add a tweeter. You could connect the tweeter to the FR with a capacitor.

That's the best part about the SLOB. It's a template for customization.

I built his smaller version, which is more of a "normal" sized speaker. I don't believe it is covered in his paper.

Default Bypassing low pass filter section

If I would like only use the bass hp filter and eq. section, bypassing the second half of the circuit -low pass filter- , from where would I connect the output in the xover? Thanks!
