Wow, these mods really work...
I just got my T50RP's. I listened to them for a bit but immediately realized their flaws. I had already ordered the mod material so here's what I did:
- Plasticine mass damped the rear of the baffle in every place possible. I put a lot in on each side, they were super damped.
- Lined the back of the cup with Silverstone acoustic foam. I didn't just do a few strips, the whole back of the cup is lined with this stuff except the curved sides because I didn't want that part to press against the plasticine and greatly reduce the volume inside the cup
- Removed the felt from the front (ear side) of the baffle (NOT the back of the driver)
- Shure SRH840 Pads
- Silverstone acoustic foam donuts that are double layered on the back half to push the rear of the pad up to get an angled affect -- it works
I could immediately tell...
- Stronger bass, deeper sub-bass (from better seal)
- Much tighter bass
- Smoother mids
- Crisper, more detailed highs, though there is slight sibilance.
- Just more awesome overall
I really liked the stock sound signature so I have zero desire to remove white felt from the back of the driver. The highs are also good as they are so I will not be doing a reflex dot. Before I poke around any more in the baffle and cup, I will be doing at least 50 hours of listening. So far, this new improved soung signature is awesome.
EDIT: I'm going to post why these mods work for my preferred sound signature.
- I'm more team treble than a bass head. I like deep extensions in the bass but I like when bass knows its place. I'd prefer it not be as forward. Well-balanced is what I prefer I suppose.
EIDT 2: I should tell you how I'm running these:
Play on Mac OS X using FLAC Files (16bit/24bit mixture) --> Opus DAC --> Bijou Tube Amp --> T50RP's
