The JBL 305P MkII - Powered 5" Two-Way Studio Monitor is a bi-amplified reference monitor with next-generation drivers, offering high detail, precise imaging, a wide sweet spot, and a remarkable dynamic range to enhance the mix capabilities of any modern workspace. The magnetically-shielded 305P MkII features dual 41W Class-D amplifiers, which power the 5" low frequency woofer and woven-composite 1" neodymium tweeter. The combined output of the woofer and tweeter offer a frequency response of 49 Hz to 20 kHz with a peak SPL of 108 dB.

The monitor features JBL's Image Control Waveguide technology for accurate audio reproduction and JBL's Slip Stream port design for improved bass response. The 305P MkII is equipped with a boundary AEQ for controlling the low frequency response when placed near a wall, as well as a 3-position HF trim switch. To ensure flexible connectivity, JBL included a balanced XLR input and a balanced 1/4" TRS input, both of which feature dented level control. Other features include a selectable input sensitivity switch that ensures compatibility with a range of signal sources. The JBL 305P MkII ships with a power cord.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
