Reactor 600 vs 900

[ogs]

Placing the 600 in a corner will probably give you more bass than you need. A Gecko is a good way to mount the speaker. When you've moved and buy the second 600, try to place the pair as symmetrical as possible. If you use Roon it's parametric equaliser is a good (and somewhat advanced) tool you can use to adjust bass response. Roon also does convolution. If you are up to it, room correction is an even better option. Thierry at HAF https://www.homeaudiofidelity.com/ could help you with this.. Good luck!
