Marvel Posted March 27 Share Posted March 27 I think it is two 210 cabinets with the wings on the sides. The A7 is way smaller. 5 Quote Link to comment Share on other sites More sharing options...

Hopefully I will be the proud owner of a barn someday. So I have room for bigger and more speakers. I bet they have plenty of bass. 2 Quote Link to comment Share on other sites More sharing options...

They are also proud of their phase plugs and diaphragms. I think the 802 had an unassailable patent for a long time. Someone sells a ferrite knock off. They don't last long on e-bay. 1 Quote Link to comment Share on other sites More sharing options...

You would probably be better off with a pair of MWM bass bins and some large modern horns for the mids/tweeter. 4 Quote Link to comment Share on other sites More sharing options...

Marvel Posted March 28 Share Posted March 28 The 210s are bandwidth limited to 100 to 1kh. https://greatplainsaudio.com/wp-content/uploads/2016/06/210-210A_basshorn_spec_sheet.pdf They are front loaded bass reflex cabinets. I would go with the MWMs as well, especially after having a pair in my house. 1 Quote Link to comment Share on other sites More sharing options...

boom3 Posted April 23 Share Posted April 23 Thanks Duke. The stock A-7s were designed to speak through perforated theatre screens, which is why a "naked" A-7 sounds shrieky. With the screen in place, the response is "reasonable" but has not been SOTA for about 70 year, in other words, since Klipschorns hit the market.. 2 Quote Link to comment Share on other sites More sharing options...
