leperclown Posted January 25, 2022 Share Posted January 25, 2022 Hi all, just wondering if anyone has tried to lighten the load of their DT50 1x12 or 2x12 by replacing the current speaker(s) with Neodymiums? If so, with what and how was the outcome? Cheers Paul Quote Link to comment Share on other sites More sharing options...
psarkissian Posted January 25, 2022 Share Posted January 25, 2022 Don't do that. These are not all analog tube amps, the digital side might not like it. Looking over the specs and frequency response curves,... it''s close, but not close enough. Stick to the specified parts. Outcome? If the power to speaker is not match and the speaker fails or the tubes and speakers fail, it can take down the system. That would leave it un-repairable. Stick to specified parts (tubes, speakers, et al). Don't try to hot rod, a Bogner hot rod it will just blow something. Line 6 does not support modifications to it's product. If something fails we won't be able to help you. Further complicated by the fact that it is now a legacy product. I don't want to see your amp on my repair bench.

Partev, Maybe a silly question, Yes, I know you state use the same speakers, although how should one choose a cabinet/speakers for a DT50 or DT25 Head? Or even with the DT50 212 vs 112, same amp yet different wattage on the 212 speakers(90W+60W) & the 112 is a 90W speaker? This seems a little confusing.

psarkissian Posted March 23, 2023 Share Posted March 23, 2023 Program for the heads are different, and slight difference in other places to accommodate different 3rd party cabinets. Modeling program for the heads is designed for that, program for the combos are not. Been that way since Spider III and Spider Valve. As I've said before, these are not all analog tube amps, so you can't get away with doing the kinds of things we used to do in the all analog tube amp days (circa early 1970's). Had this chat with a audio test analyst guy here, as we both used to work at JBL (or JBL/UREI in my case). Was picking his brain a while back for my prior comment, as he was dealing with some Neodymium speaker testing that week. Hence my prior comment.

Having said that, with a DT25 head, would the external cabinet with a 15W 16Ω VOX Blue be OK? Thanks in advance! Jd Quote Link to comment Share on other sites More sharing options...
psarkissian Posted March 23, 2023 Share Posted March 23, 2023 Sure, AlNiCo is fine. 1 Quote Link to comment Share on other sites More sharing options...
