One years later my headhone got dead due cabling issues. After suceed change the plug, it revives again. After that I just got curious about recabling and modding headphone. So I searching on the net about headphone recabling and modding then found Sunneebear's post about modding RP-HTX7. Modding is so interesting if I can add values on this cheap and weary headphone.
First thing I do is recabling my RP-HTX7 using Canare L2T2S. My skills at soldering is still not good, so I decided to pay an expert to do this. After recabling, I found that my headphone become louder (due the smaller impedance).Thanks to Sunneebear, I just got the idea about modding RP-HTX7 driver. I tried another configurations, in searching best combination of driver airflow possible. It's not just about electricity, it' is about headphone's architecture and airflow inside it.
After 2 weeks of modding and several trials, finally I got an ultimate version of RP-HTX7. The hard work is so rewarding and unbelievable. I don't have another headphone to compare with, so I just asking opinion about this mod to my audiophile friends. Here I'm gonna share my final configuration to unleash RP-HTX7 true potent.
Materials and tools:
For materials I'm using 3M Micropore, Scotch Tape and some foam from unused earmuff (has good noise absorbing)
Here is my concept about airflow inside RP-HTX7:
This is my latest modding concept:
Impedance from original RP-HTX 7 cable still needed to control membrane power.
How to Make these "seal":
1. Open the hole using screw driver (beware not to damage driver membrane inside)
2. Cover it using Scotch Tape
3. Make a tiny hole using a needle ( I was using a needle from a pair of compass), (beware not to damage driver membrane inside)
4. Make 0.5 cm foam box (four times: two for upper, two for bass)
5. Put it over the tiny hole
6. Seal it using 3M Micropore
7. Strengthen the seal using Scotch Tape/ duct tape, so it won't easily teared off.
After done these mod, I am widening mini holes (Air Intake) on the body using compass's needle (just a little bit).
Review from me personally:
The Bass is deeper, nicer, softer and not punchy anymore. Middle is so clear and nice. High/upper mid is clear, but still little spiky sometimes (fix that later). Got amazed with improved clarity, staging, and timing.
