Spica Angelus are mirror imaged and the woofers should be placed closer to the inside. The Angelus is a great speaker and deserves high quality electronics. They have a fair amount of high frequency energy, so I recommend avoiding brite electronics. Tubes work well and I had excellent results with Audio Research tube amplifiers and preamps. If you have the spikes you can tilt the speakers forward or back to align the area midway between the woofer and tweeter with your ears. With the proper tilt the desired tonal balance can be achieved.
