c'est effectivement un très beau tout petit HP ;-)

je partage pas l'avis du choix de coupure à 4,5khz par rapport à 2.5khz !!!!
Midrange driver:
The Volt bass drivers are very well behaved and can be crossed fairly high. This takes the load off the mid-range driver, so we could pick a 4�? unit, which is around the optimum diameter in our opinion.
We say this because we really want one driver to handle as much of the vocal range as possible. This is circa 300Hz to 6kHz, with the ears most sensitive range being around 1-5kHz. Our crossover points are 250Hz and 4.5kHz, so we’re not far off!
Humans are so attuned to understanding speech that any distortion in it’s reproduction is flagged up by our brains. It simply doesn’t sound correct. This is why you need to be extremely careful if you have a crossover point in this range as it can cause phase issues. So a crossover point of 2.5kHz as with most 2-way speakers is far from ideal!
