My options would be Heresy 1 with Mundorf capacitors 600 euros Clonwall replica 1500 euros Heresy IV 2100 euros My system also consists of 2 15 inch subwoofers Would you take them? Is the IV really better in the details?
I do use Heresy 1s as AV speakers. All new drivers/caps after 20+ years of constant use, and modified mid horn. Before modification, they were free to me, so the price was right.
If you go that route, I suggest stuffing the cabinets with polyfill, and putting them up, level, on stands. On the floor, there is really just one seating spot for which they sound best, but level they can cover an entire room well.
They work well, other than two things There is a lot of cabinet resonance. As in those unbraced cabinets REALLY boost ~1700hz, and some other frequencies. The recessed horns make things... different (lots of reflections before they hit the room). Which is why my midhorn is no longer recessed. You will never get a neutral sound with them, even with lots of EQ. Fun, I like them, but I don't use them for music much anymore.
Yet another options would be Heresy 3s, or even 2s. At a guess, 3s will be about 1500 euro, plus or minus. That gets rid of the recessed horn issue, at least.
The 4s would be a better choice, again, up and level. Cornwalls, I think that depends on how high your screen is, because you likely don't want those up on stands, and I am not sure how the replica might sound, it depends on parts and such. Huge speaker though. Good for close to the wall or corner placement. But definitely consider the size, wide and tall not deep. A couple of boxes or cardboard to mock up the size is worth doing in this case.
Were it me, I would likely go JBL. Of the other options, Heresy 4.
The other option is to buy the Heresy 1s, use them, then resell them if you don't like the sound. Then go with one of the other options. They won't lose value while you own them, but you will waste a bit of time if you do resell.
