JBL såklart, med sällskap av Volt med flera...
The UE4 is a four way bass reflex enclosure.
This extraordinary loudspeaker can produce 135db from 35Hz to 18KHz -3db.
Frequency response 25Hz to 22KHz -5db.
Efficiency: 94db 1w/1m.
Power handling: 300w rms, 600w music.
All the drivers are high efficiency drivers used in studio recording.
The tweeter is a modified version of the 1" dome Scan-Speak Revelator.
The high mid is the ATC SM75-150 3" dome.
The low mid is the 10" Volt BM2500.4 mounted in a 2 cubic feet sealed enclosure.
The woofer is the JBL 2245H 18" mounted in a 8 cubic feet ported enclosure.
The crossover is a second-order Linkwitz-Riley,
with crossover points at 160Hz, 800Hz and 3800Hz
and all drivers have their own impedance compensation.
The crossover is mounted externally.
Each box weight over 400lbs.
They are made with 1" thick braced MDF.
The woofer front baffle is made with 3" MDF.
The low mid, high mid and tweeter front baffles are made with 2" MDF.

They have a fabulous image and breathless dynamic.
