Well I had made a shortlist of all sorts of great drivers to work through the cabinet simulations with, including the B&C 15TBX100 (Italy), BEYMA 15B100/R (Spain), RCF LF15N401 (Italy), Selenium 15WS800 (Brazil), and even some from Lorantz (Dandenong, Australia), though the Lorantz ones were out of my budget, despite being locally made.
But I got very lucky with ebay and scored a pair of Lorantz 15″ C390X B1 for a great price. I’m told these are asbolutely amazing quality speakers.
Conveniently the auction even included some PA cabinets – though not great for loungeroom use long term at least I can get some instant gratification and get started with measurements and integrating the speakers before I start the big task of building some nice permament enclosures. When placed upside down they even position the speaker quite close to the waveguide, which is how I want the new cabinet to have it.
Not measurements yet. I’ve just quickly hooked up the bass drivers with some temporary banana sockets connected via the bass reflex port.
from the spec sheet of the manufacturer:
The C390X/B1 is An Australian made professional low frequency 15″ bass loudspeaker with a useful upper limit of 2.5 KHz. This model offers superb bass performance, high program power
handling, high efficiency, and therefore capable of producing extreme levels. The smooth response, wide frequency range, wide dynamics is attributed to features not often found in one model.
The C 390X range features rigid diecast aluminum frame, CNC precision components. The massive FE optimised ferrite magnet-assembly permit large linear voice coil excursion with efficiency.
Improved BL linearity, lower distortion , less wind noise is achieved with an undercut and flared vented polepiece. The stiff damped ribbed cone is product of our OFP technology and is molded in -house from a blend of premium air dried wood pulp and Kevlar fibres resulting in smooth controlled mid response.
The spider is made of Aramid material chosen for its high rigidity
and long term stability in demanding applicat ions. The accordion cloth cone surround assures extreme levels with minimal distortion.
I have 8 of these speakers I am looking to sell. I am only asking $210 USD or $250 NZD each.
I am happy to post them at buyers expense. They are in mint condition. They came out of a theater where they never raised a sweat and where never moved. The suspension on the cones is firm like a new speaker. They look and perform as new.

Wow, a pity I already got my pair of them! No room in my place for any more unfortunately.
Apart from the obvious ebay the classified section of stereo.net.au forums could also be a place to mention the sale.
