I wonder how the Goldwoods would work with a pair of those 15 in Sansui's I have. Might be a way to experiment without spending a lot of money. I'll still play around with something I have laying around first. And to think I thought I was done spending money on speakers.

I think you have plenty of power to drive them or any other FR speaker you desire as well as a separate amp for the Sansui's. Correct?
A low cost option to electronic or passive crossovers may be the FMods which allow a fixed crossover as well as the use of any amp powerful enough to drive the Sansui's. You can find them on the bay or at P.E. I've not used them but others here have so maybe they'll chime in.
Without spending much you could get your feet wet in OB and then decide if you want to move forward.
FWIW, Goldwoods are 20% off at PE

FR was stamped in ink on the magnet and barely visible on mine. Your Kabuki's might do the trick.
IMO, the ultimate low cost H frame speaker design uses the Goldwood GW-1858 woofer. Bass down below 30 Hz with authority. A little bigger then a 15" based H frame design but still not that big compared to many box speakers that go this low.

What sort of output levels have you been able to measure from the 18's before they lose composure? And how high up can they play?

Again an opportunity if someone is not equipped for woodworking. This one is in the CT area. Just the flat boards, JE Labs style. Just $40 with no drivers. No affiliation.

Here is a link to the page with the documentation, the predicted results, and the measured results. I cross over in the 200 Hz range to a Jordan JX92S full range driver.

I have played the 1812 Overture through them at a pretty loud volume and the cones moved but not excessively. I typically do not run my system at nightclub level volumes so I can't tell you what the SPL limit is with the 18's. But it can get fairly loud, at least for me, without showing signs of strain or breakup.
Unfortunately I have never been to the LSAF, I live in cold and snowy upstate NY, but maybe some day. I believe Bob Brines made a set of these H frames and they might have gone to the LSAF, but I may be mistaken.

Ah....right....now I remember. That's who the gentleman was who had the the 18" GW's in the H-frames with the Jordans. I was early in my audio hobby back then and hadn't yet attempted any DIY but was chompin' at the bit for a project. They made a good enough impression that when I did get around to my first DIY project it was based around H-frame subs.
"Cold and snowy".....y'all are gettin' a pretty good helping of it this year, aren't ya'? The news makes it sound like a good bunch of you are about ready to push away from the table.
I know it would be a hell of a long trip for you and maybe not worth the effort, but we'd sure be honored to have you down some time. :yes:

This winter has been very cold with quite a bit of snow, more like what I remember as a kid and when I was going to college. I remember getting over a foot on Thanksgiving one year and two feet on Christmas another year. The last 10 years have been very mild. This week has been -9 F one day and today we should get over a foot of snow, which is similar to the last couple of weeks. But in upstate NY it does not bring everything to a halt like down south, I had no trouble getting home from work (my '98 Ford Explorer will go through anything) and will not have trouble getting in tomorrow, it is handled and people are used to it. But I have to admit after spending a week in San Diego in late December I am starting to question my sanity for living here.
Maybe when my youngest goes to college in two years and the house is empty I will be able to talk my wife into a vacation down that way at the right time of year, I would love to attend. Assuming I have some money left after three kids in college, maybe one of the older ones will land a good job and they can float us some cash for the trip (seems fair).

A perfectly reasonable expectation, if you ask me. :yes:

open baffles can be a lot of fun, make no mistake about that.
There is also a lot to be said for point source radiators.
These sounded good (the MR/HF drivers have field coils; the woofers are your standard dynamic - permanent magnet - drivers)...

My wife was born in Fairport and grew up in Buffalo. Thank goodness she moved south and found me. I say that as we sit snow bound in tropical South Carolina.

Just a few miles from the house after a light icing of the roads a few days ago (it'll be upper 70's this weekend)...
...I saw two more of these during my eight mile drive to work. I'm sure a Yankee driving around around in Texas during a snow/ice episode spends half his time laughing hysterically, the other half wanting to put his fist through the windshield.

Looks like a 4WD pickup (?)... interestingly, the laws of physics apply to them, too...

Here's a low cost 10" cast frame woofer that's becoming a favorite for OB's over at AC. Two per side would be sweet @ $26.99 each plus today you can take an additional 14% off with code VTD402.
My friend bought 6 during an even better holiday sale. I've see them and they look dang expensive with their nice cast frames and terminals. If you want to read more about them check out the Hestia OB threads at AC. They're also used in the prefab H-frames ( H-bombs aka storage cubes from Target )
