Dynamo A-25 2 way speaker with 10" woofers. These are comparable to Advent Large and Advent New Large Loudspeakers and Matantz Imperial 6 speakers all with 10" woofers. The Marantz do have a warmer sound than the others . I have that Marantz Imperal 6 and The Advent New Loudspeakers. I would love a pair of these.
