Thanks Altec Best.

These are for home use, conventional stick and drywall. A relatively large room now, 16x24 and 20 foot ceiling open on one end to the rest of the house, but will likely end up in a smaller family room in a town house.

Currently a Yamaha HTR-5590, 100W/channel but I hope some SET's are in my near future. These components came from a pair of A4's handed over to me by a friend in NY. The cabinets were ruined in a flood. I mistakenly passed on the HF horns which included the y-adapter to handle the pair of 288s, as they would not fit in my car. Finding the larger port horns now is difficult. 'DOH!

I was hoping to sell two each of the 288s and 515s to finance the rest of the build, but I am a fan of bass (love those 32 and 64 foot pipes) though I'll keep my Velodyne DD-15. So if you say I need both 515s, I trust you though that will challenge me as far as cabinet size is concerned. Need to decide whether to build or buy cabinets, too.
