You might also consider the JBL LSR6332
monitors. They are $1560 shipped each. They are some of the best measuring speakers you can buy at any price. They are THX pm3 certified which means they can be used to mix and create THX sound tracks- that is NOT an easy certification to get. They won't have the dynamic range of Pi, JTR, or JBL cinema, but they will still pack a punch and be more accurate besides. According to this SPL calculator
they could still hold reference level sound in your room with headroom to spare. If it were me, it would be a choice between the JBL LSRs and the Pi Fours. The Pis will have great accuracy and insane dynamic range and the JBLs will have great dynamic range and have unmatched accuracy. If you want a speaker with similar levels of performance, you will have to work your way up to the higher end $11k pair Genelec monitors (very nice!), the $20k Revel Salon 2s, or some crazy expensive JBL Synthesis setup.
If the Pi Fours are too big, consider the Pi Threes
. The Pi Three measurements
have flatter on-axis measurements anyway, and they will still have lots of headroom to spare. As with the Fours, I would get them with upgraded drivers. The Threes have terrific measurements.
