Possibly, but after Bowtie's opinion they suck, I suspect that is indeed what I heard. Towards the last bankruptcy Altec was having QC issues. But something comes to mind about the 604's...were there not mags on later 604's that caused weak bass? The 604 was 515 based. So might be the same mags? I have very limited exposure to ferrite in both so asking, not offering an explanation.
