I have very old pioneer speakers pw12a woofer pm6 mid and pw3 horn tweeter. Thau all work and are inclosed in a corner shape cab. What type of cab should I make for them. They also have a dividing network box and volume for top end frequency. .thanks
Same as in this thread? https://www.diyaudio.com/community/threads/does-anyone-know-anything-about-these.398021/

The cabs had huge rectangular port and I cut out at the bottom. So I closed them off. Just very nice mid. I today removed the bottom piece of wood that closed it off still nice mid. But if I put my head in the speaker box it sounds awesome, how do I get that sound outside of the box so I can hear it.
You know, since the midrange driver ( squeaker) and the tweeter are covered in the back, they don't need any enclosure. Not that I say that they might be set naked, but...
You would focus then on the woofer cab only. I would make some cubic-prism-anything that leaves one side near to the woofer free to position the two other driver units, eminently on the vertical axis. This way you could position the whole set anywhere in the room and experiment with the two speakers aiming at you
The crossover with the shell is gorgeous, too! ( pics from the Thread above..!)
Problem is ...ageing of the capacitors, so the shell must be lifted in order to INSPECT!

Everything sounds good what your saying but the heart breaker is that I only have I set of 3 speakers. So I have to build something,, what I have at the moment with 2 other speakers to compliment the one so I get a 2 for stereo at low volume and this for a main centre sound if you get what I mean.
A bit off topic, I have a very close family friend who is a good carpenter. He can help to build a new cab. Between us im going to buy as many as I can afford goodmans axiom and audium vintage fullrange woofers, I've heard that they sound delightful.
Yes, something in the lecture of the thread suggested that it was one cab...
So not more stereo ultrasound!!
And...I wouldn't call those woofers and all the vintage stuff " full range" since they're limited...a modern aluminium/ ceramic/graphene! 4" easily outperforms them in the bass range requiring 1/5 space and mantain pistonic behavior till break-up (well, they are small...) due to cone rigidity ( and the membrane being more soundproof than paper.. ) and roll surround + good excursion..
So you cannot "feed" those (that) woofers with synthetic LFO (like the group!) at medium-hi volume.
In short, I would make a mono speaker with all the sighteable things in sight in a 50's and steampunk style. Woofer cab in formica, of course, and solid copper wires covered in cotton 😉
Amp is a beautiful valve player. I have 2 pro9 tl speakers no problem there. But I have only 1 set of the pioneer vintage for one speaker only.
Amp has only one Chanel for one set of speakers. This project is for my sony ta1144 that has 2 channel a and b. Im looking for a pair of mission 737r to repair my mk2 mission 770. The pioneer set is to provide a larger more open sound stage by having the pioneer in centre and 2 other speakers as satellite to widen sound, if you get the picture.
