The ESL-2805 is the smaller of the two models using six panels rather than the 8 of the larger model. The inner two panels of the ESL-2805s construction, again utilise the concentric anode rings for point source imaging, and the outer rings are again linear in their response. Whilst absolute bass extension and dynamic ability is less than it's larger brother, the ESL-2805 offers a sublime performance.

The clarity of mid-range for which the Quad are most famed is fully in evidence, as is the sparkling detail and transparency that has long been the hallmark of this series. Their response characteristics are virtually identical and a base weight of 34.8kg together with the rigid bracing, ensures they are suitably deep in bass and dynamic enough to fill all but the largest of listening rooms. For the Quad aficionado without the need or desire for the additional bass extension of the larger model this, the smaller of the ESLs is still regarded as the pinnacle of electrostatic refinement.
