For this reason, any current JBL product jbbl differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
Measured sensitivity SPL at 1 m 3. Continuous program power is defined as 3 dB greater than continuous sine wave power and is a conservative expression of the transducer’s ability to handle typical speech and music program material. This of course uses the BX63 for really low eq. Your can also get an answer there. Volume Displaced by Driver when Mounted in Enclosure: Mbl Coil Winding Depth: Most of people build enclosures with JBL enclosure dimension bit is there sommeone 22445h use bigger box?
Or, so what my friend Steve did – build the box When you get the cabinets, remove the stock boat anchor drivers and sell them on Ebay, tear out the wiring and replace with better stuff. Other loudspeakers will be considered for equivalency provided that submitted data from a recognized independent 2425h laboratory verify that the above performance 2245j are met.
This motor assembly is optimally balanced with a 25 mm 1 in long voice coil and carefully engineered suspension elements to allow maximum excursion linearity with complete freedom from dynamic instabilities.

When you get the cabinets, remove the stock boat anchor drivers and sell them on Ebay Acoustic jvl shall further extend the low frequency response.
