Hey guys, been lurking for some time and decided to jump in. Very new to all of this and looking forward to learning alot from this group. I have a home theater project I am working on and I am really interested in the Klipsch KL-650 clone build as well as building some surrounds to go along with those. I would love to be able to say that I built all of the speakers in my home theater. The challenge in all of this will be the crossovers. I am completely at a loss on those. If anyone can point me in a good direction on crossovers for that specific build I would be grateful (I am not even opposed to purchasing pre built crossovers). I also have some existing surround enclosures from a theater liquidation that I acquired and I am not impressed with the drivers in those so I will be posting in the next day or so for some advice on drivers and tweeters for those once I can take some pictures and get some measurements.
Hi Wingnut. (your nick made me smile and chuckle)
The crossover is in the second post on the thread ( https://toidsdiyaudio.com/community/postid/3780/ ), both in schematic form and physical soldered form, spread out to clearly see the connections. Since these are just coils, resistors and non-polarized capacitors, you don't have to worry about directionality (which end goes to what).
When you go to measure the boxes, you'll want to measure the inside (to calculate volume), the size of the openings, and the distances between the openings themselves as well as to the adjacent sides. Material thickness would be a nice thing to know as well. That way, we won't suggest something that won't physically fit.
