Omega Super 3 Bipole speakers, ebony finish with magnetic grills in excellent condition.
From a Google search:
The Super 3 Bipole uses Twin front and rear firing 4.5 Fostex drivers. By incorporating twin drivers front and rear firing the Super 3 Bipole is able to reproduce more complex music with more dynamics and low end response than the Super 3 while producing a huge, deep and wide sound-stage. The music signal is shared by the twin drivers which increases sensitivity and lowers distortion. The Super 3 Bipole has dual sets of binding posts which are connected to the drivers individually which allows the Super 3 Bipole to be run in either 4 or 16 ohm impedance. Jumpers and diagram are provided for easy switching between 4 on 16 ohm, Bipole and Dipole as well as Monopole (front driver only) or Bi-amp.
1: Bipole 4 ohm
2: Bipole 16 ohm
3: Dipole 4 ohm
4: Dipole 16 ohm
5: Super 3/8 ohm
Setting them up was a bit different than the other speakers and they do need some room to breathe from the rear wall. I got the best sound with the speakers toed in. They have great bass and a very smooth mid-range presentation. The speakers truly disappear and the soundstage is very wide and deep. I've tried all my amps with them in 4 and 16 ohm and they performed great. I hooked up the 2A3 in 4 ohm and the amp sounded great this way. Very powerful.
They Sound most like a Super 3 as the design is based in it. Each driver has the same internal cabinet volume as the Super 3.
One of the important things about the design is it has to start off with a wide baffle so most cancellations will be avoided. They have a very wide soundstage and tend do disappear in the room. In Bipole the sweet spot in front of the speakers is wider.
The Dipole is when the drivers are out of phase. Both versions will give a greater soundstage and much wider and deeper than monopoles. The dipoles will have a bit more focus and clarity due to the side cancellations or nulls, but the sweet spot is a bit narrower than the Bipole.
