It's hard to equate these experiences & to optimise your speakers & speakers positioning unless you can measure what's going on with say a UMIK microphone & REW (the most popular low cost option for measuring what's happening with your speakers in your room). It's really a great investment in order to get your best sound, but it does require some effort to learn how to use REW and to understand the theory around measurements (& room EQ) to enable you to optimise your speakers. I did go through a long stage though where I just listened to my 308p mkii with an Anechoic EQ and no room EQ, just relying on the Anechoic EQ - so effectively just letting Anechoic Flat speakers roam free in the room so-to-speak, and it was a good experience, and probably the best way to do it if you're not gonna have any one listening position - ie you want it to sound the best it can be from anywhere in the room. So you could still do an Anechoic EQ on your speakers using Amir's measurement, hell you could even use my Anechoic EQ that is listed in this thread somewhere. But for dedicated listening at one listening position then you'd want to be using Room EQ, which is achievable through using UMIK & REW.I moved my 308p from the wall to the middle of the room, and for some reason they sound flat. They have way more air behind them now, but they sound anemic. Bondary EQ and HF Trim are set to 0. Isn't BEQ for compensating when really close to a wall? I've had mine set to 0 before the move since they were a few inches from the wall. Also, what's the risk of things crawling inside the speaker hole? Does it matter? I live in a fairly cold climate with few bugs. Is itr common to filter these holes, or does it change the sound signature?
For a short & quick fix regarding Anechoic EQ, just flip HF Trim Switch on the back of the speaker to -2dB, that takes you a lot of the way there to an Anechoic Flat Speaker, so do that first.
(Room EQ is designed to sort out your bass for your listening position).
Regarding creepy crawlies infiltrating your speakers, I've thought about that, but I've got my ports plugged now because I'm using a sub so don't need the low end extension of the speakers, but I wouldn't worry about it - just hoover up the spiders and critters in your room fairly often to stop infestations, I do have quite a few spiders in my place & I quite like that because I like them getting the germ ridden flies, so I just clean up the cobwebs that eventually form around the speakers & sub, lol, spiders are useful though, but I don't want them living in my audio gear, they probably have more sense anyway!
