Another option would be the Dayton Audio DSP-408 or something similar. It gives you 4 channels in and 8 out and a multitude of controls, including volume and crossover . It's $179. It's overkill, but will work. Besides, you can play to your heart's content.
Bi amping with two different pairs of monoblocks
I'm wanting to bi-amp my Canton 1K speakers with my Triode TRX M845 monos doing the LF and borrowed Vacuum State 300B monos doing the highs.
The speakers each have 4 binding posts with links between them which I'll remove which will separate the H & L frequencies
My source is an Oppo 203. I'm thinking of using rca Y splitters like these AudioQuest - Hard Y-Adapter RCA Splitter (1x Male to 2x Female) - Music Direct
Will this layout work for me or does it need tweaking?
