Five drivers share the band. A Dynaudio Esotar dome tweeter covers the top, two 6 inch carbon fibre midrange cones with 3 inch voice coils take the middle, and the two 12 inch woofers sit in a compound, or isobaric, arrangement in their own compartment, one driver working behind the other so both move together. This loading reaches low frequencies from an enclosure far smaller than a single woofer of that size would need. EgglestonWorks quotes 18 Hz to 24 kHz at -3 dB, 88 dB sensitivity and an 8 ohm nominal impedance with a 6 ohm minimum. That is a benign load which does not stress current delivery, yet the moderate sensitivity asks for generous power when deep bass and high levels arrive together. Two sets of rhodium binding posts allow bi-wiring or bi-amplification, so a pair of stereo amplifiers or four monoblocks can drive the bass section on its own. The SE upgrade brings improved crossover components, better internal wiring, new binding posts and a new paint finishing system.
How it sounds
The isobaric woofers give the room deep, weighty bass that keeps its shape, so drums and large-scale music carry a sense of live presence. The doubled midrange surface keeps voices full at higher levels, and the wide soundstage lets familiar recordings reveal small details.

To create a first-class sound reproduction, the developers used 5 high-quality drivers organized in a very interesting scheme. The high frequencies are represented by the Dynaudio Esotar inch tweeter, which is currently one of the best and most expensive in the world, the mid frequencies by a pair of 6-inch Morel drivers with carbon fiber diffusers, and the low frequencies by a pair of Dynaudio 30W100 installed in a separate compartment according to the isobaric load principle, which allows for powerful and deep bass with very small own the dimensions of the cabinet.
