Model no:   SP-3W4D

This speaker system utilizes super high quality speaker drivers that have good frequency accuracy and phase coherence over the whole spectrum. Its precise and specially designed highly efficient crossover network allows them to work well with amplifier outputs as low as 8.5W (e.g. 300B single-ended) . You will hear unbelievable low frequency regeneration from this small speaker even at low power inputs. Both drivers have a very high dynamic range. The tweeter is made with a pure silk wide dispersion, super light weight dome diaphragm. The voice coil has a liquid magnet for cooling and damping. (The same design as the Dynaudio Esotec D-330 tweeter). These speakers are matched for +/-2db accuracy between left and right. The two 7" woofers are made with specially  coated paper cones and super durable but soft rubber surrounds providing a very high dynamic range with no noticeable distortion.

In our opinion this speaker compares head to head with those selling in the market for US$8K-20K .

The speaker drivers are made in Denmark utilizing super rigid die cast frames and a large 64oz magnet for each woofer.

The Cabinet is made from 1" thick MDF to eliminate resonance even when driven to very high output levels.

Same price up-grade option:

The right photo shows a separate chassis version, which separates the speaker into two chassis, the upper one contains a 5.25" mid-woofer + 1" silk dome tweeter (or 2 x 3/4" mylar dome tweeters, becoming a 5 driver version), the lower chassis contains two 7" woofers, with this upgrade, you can time align (move the upper one back and forth) to obtain very high accuracy in the sound stage and focus. This is our newer design option with the same price as the old version.

Various types of finish and colors are also available.
