I am the fortunate owner of 4 each 288B's and 515's, and two N500C's.

At this point I am not sure I have the room to utilize a 210-like speaker, so am thinking of making two sets of two-ways with one each HF and LF (need two more x-overs, of course), or selling the extra drivers to finance the refurb, cabinets and HF horns.

I intend to send the 288s into GPA for the mod and new diaphragm's, and two of the 515s as well as they have some rips in the cones.

Here are my challenges for which I could use some advice; do I stick with 24 ohm diaphragms or opt for 16 or even 8?

Do I splurge and buy some A7 cabinets off eBay or are plans available to build something better? And what HF horns would I be forced to use in the case of the A7 cabs, as 1.4" horns seem to be in shorter supply than the 1" models. Home use but I tend to play orchestral rock and pipe organ music at relatively high levels.

Any advice is greatly appreciated.
