The second speaker brought was the Genuin 3 set up below. It weighs in at €8.500/pr in Birch veneer and about 30kg. Its sensitivity spec of 92dB in-room duplicates the smaller rear horn but the tweeter becomes a 45mm Titanium unit with 1-inch horn throat and the mid/woofer grows to eight inches. The crossover point hovers at 1.3kHz and the enclosure runs 25mm Birch Ply panels with a 50mm double-thick front baffle.

Unlike the smaller rear horn, the Genuin 3 sports a separate wood-clad tweeter horn module which can be moved for time alignment but then requires unbolting the woofer to gain access to the adjustment screws. The Genuin 3 terminal plate runs biwire Eichmanns jumpered with wire leads and between them, the impedance correction circuit jumper which can be removed for transistor amps. Personal experimentation determines whether with or without impedance correction is preferable in the listening seat and for a given amplifier. As the front-firing port shows, the Genuin 3 is a bass reflex design. Unlike the two rear horns which use metal bars to mount their spikes or optional footers, the Genuin 3 incorporates a dedicated black plinth. Its front is narrower than the enclosure to bestow upon the latter a somewhat floating illusion from the seat.

The edge mitering of the enclosure exposes the striated Ply layers while the machined MDF horn is painted flat black, the mounting flange textured black. The decorative engraved line pattern on the front baffle varies from speaker model to speaker model.

The Big Fun 20 relies on a 65mm Titanium tweeter and also enlarges the horn throat to 1.4" to apply a high 1:10 compression ratio. The mid-woofer coming in at 1.2kHz and 18dB/octave acoustical is an 8-inch paper sandwich with foam core and built to Thomas' specifications by a pro audio drive unit manufacturer in small custom batches.

The externally adjustable tweeter horn module adopts an exposed metal mount. The loaner's only two items not finalized were the textured paint on the rear tweeter housing and the hair-line calibration sticker surrounding the locking bolt to assist precise physical offset as determined by a listening distance chart in the owner's manual.

With the module removed, the enclosure top shows the two banana terminals for the tweeter connections.

The terminal plate duplicates the one from the Genuin 3 (correction network jumper removed for illustration).

Unlike the smaller rear horn, this one applies only half the internal damping though the overall geometry of the folded horn is quite similar.

This enclosure too is crafted from 25mm Birch Ply with a 50mm double baffle. Proper T-nuts allow high torque bolting of the woofer basket for proper coupling. The crossover hides behind an access panel in the horn mouth flare.

The impedance correction circuit consists of the following three components:

All crossover parts are matched to 1%, all drive units are pair matched and extensively rebuilt and recalibrated over roughly 1.5 hours for each driver.
