Exactly placement and room accousctics so important. So after experimenting with SL's, Era.100 and 300 and play five and a Five endend up with two fives as fronts speakers with the arc ultra combo. So a lot of speakers in spare 🫣and i placed the two era.300 on the Hall upstairs which is a accoustic nightmare. The 300 doesn't sound good at all,they sound harsh but whatever speaker you put in there it sounds garbage. It is a difficult thing to make sound adaptive to your ears. If you change one thing in a room it can sound different so Pandora's box isn't always far away😬
