Any advice on shifting the pinna gain peak on RAB-32257 from 4k down to 3kHz?

There are all sorts of info already posted in this thread regarding RAB. Start with the proper zobel network. Adjust tube length and damper accordingly.

I saw prices for $199-250-500$ depending on model

value plummeted it seems

 

[justsomesonyfan]

just look at these beauties
as far as I know these are AMT full range flagships
they are expensive, but I have seen cheaper models from the same manufacturer ($200-250)
and oxygen here for 500

[justsomesonyfan]

I haven't seen many reviews for them, have you owned any and which ones fit?

I owned three, I don't know the names, there were two hybrids which were 1dd/1amt, and those fit well, and one amt only, which did not fit very well.

Got my IEC-711 clone calibrated, IEC60318-4. Measurements of KZ ZSX and my DIY 10mm planars, with physical tuning only. The highs are a little shimmery on the planars but details is there, and with the right tips and good seal, sibilance is minimal. I posted dayton Imm-6 measurements earlier in the thread, these planars are my daily drivers. I might almost have more listening time than build time at this point, a few years later

Edit: it is ZX ZAX, not ZSX. Just there for a comparison on dB level.

Hi Guys, i need a help with my Blon blo3 iem.

I removed the nozzle filters because of dust accumulation and sound is not coming properly in one side and i lost the stock filters.I'm using foam used for microphone cover foam, but even after that I'm hearing sibilance. I don't know how to control sibilance.i can't order nozzle filters from AliExpress, because it was banned in my country. Is there any other way to reduce sibilance?

Find some open cell foam sheets, maybe 1/4" thick maximum. The microphone cover may be too thin, try multiple pieces. Cut small circles of the foam, and insert into nozzle. Try different types of foam

Quick question for anyone who's 3d printing their shells with standard resin, and then giving them a final coat of fotoplast lack3.
Are you sanding your shells before adding the lack3? Or are the print layers small enough, that the lack3 will fill them in and still give a smooth finish.

I'm using a photon mono 4k which can get down to a pretty fine resolution. I sanded my last pair a little bit, but am I just making more work for myself?
