Напольная акустика — Tekton Design 2-12 PERFECT SET

The 2-12 Perfect SET is a tall tower speaker made by Tekton Design of Orem, Utah, listed in the Full Towers category at USD 3,150 per pair. As the name indicates, Eric Alexander designed it for single-ended triode amplifiers, which typically deliver only a few watts, and the maker says it needs very little input power. The speaker is made in the USA.

Key specs that matter

Two 12-inch drivers handle the bass and midrange, and a triple-ring polygon array of small high-frequency domes covers the treble. The maker gives the frequency response as 30 Hz to 30 kHz, sensitivity as 100 dB at 2.83 V and 1 m, and nominal impedance as 8 ohms. The speaker needs as little as 1 W RMS and accepts up to 300 W. Each cabinet measures about 1,562 x 356 x 432 mm and weighs about 54.4 kg.

Engineering and use context

Single-ended triode amplifiers usually offer low power and a high output impedance, so a speaker for them needs high sensitivity and an easy load. The 2-12 Perfect SET meets this with its high sensitivity and easy nominal load, and the two 12-inch cones provide a large radiating area that moves plenty of air for little input. The treble array belongs to Tekton's patented design, US Patent 9247339, which arranges several low-mass domes in rings rather than using one conventional tweeter. Buyers can order bi-amp or bi-wire terminals for an extra USD 75 each, choose paint colours and gloss levels, where high gloss adds build time, and add grilles, which ship separately, or different footers. Beryllium domes are among the tweeter upgrades Tekton offers for its arrays. The 2-12 name refers to the pair of 12-inch drivers, which is what separates it from the 2-10 version with its pair of 10-inch drivers.

Pairing

A 300B or 2A3 SET amplifier of a few watts is the intended partner, and push-pull tube or solid-state amplifiers also work within its power handling. The heavy cabinets suit a room of 20 m2 or more, and the 12-inch drivers give enough bass for many systems without a subwoofer. With the bi-amp option, one amplifier can drive the 12-inch pair and a second, smaller one the treble array.

Alternatives

The Tekton Design 2-10 Perfect Set is a smaller SET-oriented tower with two 10-inch Pendragon woofers, a seven-tweeter array and 95 dB sensitivity at USD 2,300 per pair.
