Bennett, I just checked that ad and they are sold. I don't know if you bought them or not. But I can tell you that those Tyler cabinets appear to be a bass-reflex design, and that is not the ideal enclosure design for the Lowther. However, they will work. The drivers pictured in that ad werre the older series Lowther DX3, and those are good, but not nearly as good as the new series, which have made some important changes in the design, to eliminate the characteristic upper midrange peak called "Lowther Shout". This is a certain area of the frequency response in which the whizzer cone and larger cone resonate together and cause higher output at this frequency, which is in the upper female vocal range. It tends to sound very forward in this area, and some people find it disturbing. The new series of Lowther drivers have a rolled-edge on the whizzer cone and a type of de-coupling of the whizzer to eliminate this effect. Also the outer suspension ring is changed to improve the smoothness of the transition of the sound waves to the cabinet face(baffle). All the new Lowthers have this, and that is why you should get the new series. And I would recommend a more "Lowther suited" cabinet design. The claim that those Tyler cabinets go to 30Hz is unrealistic, given that Lowthers have an impedance spike up to 50 ohms at the resonant frequency of about 35Hz, and it is unlikely that any amp will be able to overcome that. So the realistic bottom end on Lowthers will be about 40Hz.
If you did get these Tylers, they will work but they will not be the best. However, they can be used to "get your feet wet" and until you can try some more proper cabinets later. Let me know if you did buy these, because I can turn you on to some tweaks that will help the "shout" on these older drivers.
