Sealing the port of only one speaker (stereo setup)

Hi,
I'm hoping that this is a quick and simple question for someone to answer.

I have a far from optimal (!!) room layout: stereo only, no sub yet. 3mx3m room with the speakers wall mounted too high (1.6m) and angled down and also with the speakers very off-centre because of a door. Left speaker is close to a corner, the right speaker is almost in the middle of the wall. I can't change this for the foreseeable.

I'm waiting for my miniDSP Flex and microphone to arrive and I'll measure then and see what can be done. Meantime I was messing around with REW's room simulation feature and it suggests something that feels *wrong* to me ... but I don't have the experience to know for sure;

REW predicts the best (least bad) response by having a PORTED left speaker and a SEALED right speaker ... sounds crazy to me :) i.e. take the port bung out of the left one only. I'd never considered that sort of treatment.
At this stage (before I can actually measure) I'm just interested more than anything - is this a thing?

Thank for any thoughts and insight!

Yes, and I've done it. It works quite well.
Thanks! I wanted to get a sane opinion on this before I tried it ... to balance out the irrational noise in my head that would have stopped me hearing properly! Appreciated

This might be a very amateurish way of reducing sub-bass volume without using EQ. It works though.

But if you don’t have subs and once you got the flex i would not recommend it because you’re robbing yourself of output at and above the tuning frequency of the port.

Absolutely! I plan to measure (with & without the plugs) and try to sort things out properly using EQ when the Flex arrives - this just surprised me. Thanks for the reply
