Hi,
- Here's a comparison of frequency responses for the old 604E ( circa 1971 ) vs GPAs' 604-8H-III ( 2009 ) .
- I've stretched the vertical scale ( of the originals ) so that any interested party will get a better idea of what's actually going on .
- The sources for the FRs in this collage / are / the Altec 1971 Monitor catalogue ( located here in the Lansing Library ) & GPAs' pdf product sheet for the 604-8H-III found over at the GPA website .
- This picture is also acting as a 'linked source' & is presently displayed over in this thread /at Todds' Altec Hostboard .
>< cheers
