Hey everyone,
have a look at the attached picture. These are my speakers and I love them. BUT in my opinion they have a flaw in the d'appolito design considering the BMR-Tweeter-BMR arrangement.
The distance of those BMR from each other around the tweeter center-to-center is 23cm. This would imply a maximum crossover frequency of 1450 Hz for d'appolito. The real crossover is around 2000 Hz. I think this is mostly a visual appearance decision.
But here's the thing: technically it's no big deal to swap the lower BMR and the tweeter. You can even swap the cables so the crossovers stay correct.
So my thought was switching BMR-Tweeter-BMR to BMR-BMR-Tweeter. This would result in a distance of 12,5cm and a theoretical maximum crossover frequency of about 2700 Hz which is more or less ideal for dispersion. I know it's not a real d'appolito anymore but I think there are only benefits to gain from this. Also the tweeter would be lower and more on axis with the ears when sitting down.
Is there a flaw in my thoughts?
Edit: Noteworthy - the small Low-Mid-Chassis above and below the BMR have their crossover at 450 Hz and have a distance of 60cm which implies are crossover frequency of 550 Hz, so these are placed pretty ideal and there's nothing to worry it seems.
