The distance of the back wall to the rear of the VR-22 is part of the "tuning," so you might want to experiment with placement first. At 500 hours you may need to install more Dacron into the vent, but push it past the vent into the bass chambers. That Scanspeak 8" woofer is far more powerful than any other small woofer/midrange we have ever seen or tested, so it will really energize the room like a very large floor standing model. However, the speaker itself is flat in response down to 32Hz.
Of course, if your room has dimensional ratios that introduce peaks into the sound due to standing wave Eigentones, you will need to either change speaker/listening positions or build some bass traps specifically tuned to the frequency of the peak. If you see the bass response graph of the VR-22 (published on our Facebook page) which was taken in our semi-anechoic chamber, the response is close to ruler flat. The speaker isn't causing your room to lift the bass at certain frequencies, the dimensional ratios of your room are the issue. Call us at the factory for assistance, we're here to help.
Happy Listening,
