1. It's a real pain to reverse
2. You have to crack the cans open to do it, risking cracked plastic.
3. While it increases bass it does so at the cost of the overall balance.
I just think it is better to EQ or roll pads because you can't A/B test the venting mods...you are kinda stuck with it...YMMV.
all very good points.
I am curious how similar the 225 will sound to the RS1 if I vent the 225 to match the RS1.
