I was talking to Stace,AKA Geezerrocket and he just built a pair of these Betsy open baffle point source speakers out of a sheet of maple wood.The drivers are US made and cost 110usd a pair with cloth surrounds.He sent me a video of them and being a point source,these little gems are impressive.
Has anyone else messed with these?

 a dipole planar tweeter off a series film/oil cap.

? I've never really liked the sound of whizzer cones, except those with a felt or other absorptive backing. Like the Wharfdale RS8DD? and a Goodmans or two.

And then you add a big (15 -18") high Qts & Low Fs dipole bass driver!

;-)!

And then a 3-way using a smaller WR middle driver looks more rational, covering say 100-200 to 3-4K.

;-)

You - could - still have 1st order xovers, and would have to angle the baffle back.

Wouldn't be as affordable, but it might sound as good and might play a lot LOUDER off just a few watts.

Hi Stace!!

 A little better but it's sore on the lower right back.

Beautiful, great work Stace! I am going to build...., posted on December 1, 2016 at 19:46:42

 A pair of open baffle speakers based on Joseph Esmilla's design.

I'm starting with a pair of 6" vintage Pyle drivers with whizzer cones, but they will be adaptable to more ambitious drivers if I like the result. Joseph's design can be made from a single sheet of Baltic birch ply, but, as usual, they will have neither the beauty, nor the integrity of Stace's build.

But I'm moving slowly as my tube gear is in boxes and I'm plumbing the world of M
Naim right now......but that off topic.

 If - you build a big enough OB to do deep bass ....

you could segue gradually into a 3-way, still with 1st order xover slopes, and deep bass.

Tim;

It is true that if you build a large enough baffle that there will be prodigious bass however, you will lose imaging. Like most everything in life it's a series of trade offs or compromises if you will.

I have some Eminence CW 1526 15" at frame woofers laying around. Maybe we'll go after more bass with those.

 Hi Tim,

If I remember correctly, Thorsten and others were recommending attaching foam to the back of the wizzers on pro speakers like the Eminence. Actually, I have a few full range and WR vintage speakers, including Norelco (Philips), Chrysler, Mitsubishi (Diatone) and others. They did not get much respect here, particularly the Japanese stuff, so I usually only paid a few dollars for them. While not the P-610 that everyone wants, it is extremely similar and also is Alnico Magnet. It sounds quite good with its matching cone tweeter in an extremely thin, crappy looking cabinet. These Japanese speakers still show up in thrift stores for cheap, because the primarily came with cheap, all-in-one stereo's that have long since died. A lot of them are in Radio Shack and Lafayette cabinets, that were paired with inexpensive electronics. You can also find them in Kenwood (Trio), Pioneer, Sansui, and others cabinets. On this side of the pond, it would be wise for a budget minded audiophile to take your advice, and go searching there thrift stores. It won't cost much every if you get burned a few times.

The other thing that is still readily available cheap in thrift stores are subwoofer from home theater systems. All you need is a tweeter. The Foster FT17 is capable of the job. There is also lots of good vintage stuff.

 You really should consider a Zaph SR-71 build. An Amazing speaker that does everything well. Very relaxed and natural with an excellent midrange, treble, like I said it does everything well!!!!

Obviously it's a monitor type but it does go down into the 40's. Paired with even a modest sub it sounds amazing using both my Sherwood and Latino 70.

Charles;

I already own a excellent pair of large monitors - the Paradigm Studio Reference 40v3. I don't see any reason to have a duplicate card in the deck as it were.

They have had their crossovers rebuilt with a combination of Mundorf Supreme silver & oil caps and bypassed with Wima mkp 1837 polypropylene caps. They are a very good sounding speaker that do many things very well, but when it comes to speed and space with well recorded "acoustic centric" music these Wild burros can flat bring it.

I will have my horns back in February. The can play at ridiculous spl's, but I need more room for them to stretch. When I have them in our 20' × 28' × 9.5' living room they sound sublime. In my listening room they're more pedestrian.

Hopefully we will put a guest house over the garage next fall. Guest house is a code word for deluxe man cave.

If I buy anything it will be a pair of Spatial M3 Turbos. They are a dipole as well but can play anything, and louder than I can stand with zero strain. Maybe my tax return will get lost in Utah.
