The maximum SPL of the CBT36 is frequency dependent. It’s highest from 100 to 300 Hz and then rolls off at 3 dB/octave for higher frequencies. For more details see Fig. 32 later in this section. Here are some approximate numbers (short term peak SPL is 10 dB higher). These numbers were estimated by measuring the system at 4 m (about 13 ft.) in front of the system and then referencing back to 1 m.
80 to 300 Hz: 124 dB (For one minute or less)
800 Hz: 120 dB (For one minute or less)
8 kHz: 104 dB (For one minute or less)
Recommended amplifier power: LF: 50 to 500 watts RMS, HF: 50 to 150 watts RMS • Power handling: LF: 45 volts RMS (500 watts @ 4 ohms), HF: 25 volts RMS (150 watts @ 4 ohms) • Impedance (LF, HF): 4 ohms •

Also see that the CBT36 is a 4-Ohm nominal impedance speaker. That makes the 2.83V input a 2W input. It is also only 79dB sensitive with 2W in at 8kHz. That means that to hit that 110dB+ short term peak, you would need Over 2000W of power (1000x power increase for 30dB SPL increase to get to 109dB, 4000W for the 112dB that is graphed at 8kHz). The rolloff in the HF region is not trivial, and the drivers at the bottom of the array are being taxed very highly, I would bet beyond their linear capabilities. Like I said, for certain applications, CBTs are awesome. but they are not best suited to high-spl applications, especially if budget is a consideration. I think the design concepts are elegant, the aesthetics are great, but IMO, for reference movie playback, they are the wrong tool for the job.
Εντάξει ας αφήσουμε τα 110db + αλλά δεν φαίνονται εύκολη υπόθεση.
Αν ο κατασκευαστής έχει βάλει και τους ενισχυτές φυσικά και δεν με νοιάζει η ευαισθησία, τώρα όμως;
Δεν πρέπει να το κοιτάξουμε;

χαιρομαι οταν μπαινουν λινκ που με δικαιολογουν
διοτι αμα ειναι κατω απο 80db θα χαρισω αντι για 4,5db τα διπλα
