4 way all tube balanced electronics crossover system (12db/oct)

This is a super high-end tube four way crossover system. The cut-off slope is 12db/oct, which makes it very adaptable to different types of speakers and amplifiers. 24 step crossover frequency selector for each band (you can specify the frequency range you want, then we will design and make 24 even divsion).

With this crossover system you will experience heavenly details within the music, every music note flowing in front of you effortlessly . Clarity without boundaries which conventional system don't even be able to compare with

External separate power supply with built-in super rectifier (default tubes 805A x 2 pcs), selectable choke. 5V/10V filament voltage selection. You can use 845, 211, 872A, 805A...etc, with our 845 to 300B converter you can also use 300B and other compatibles.

Use 6SL7 x 4 for the front row and 6SN7 x 4 for the rear row , you can use tube converter (12AU7 to 6SL7 converter) and be able to use those 12AX7, 12AU7, 12AT7, 12AY7, ECC81, ECC82, ECC83...and all their compatibles.

All solid aluminum chassis, not possible of being magnetization like the iron chassis, which is just use to increase the weight and trying to make it feeling worthy for the brainwashed vast public.

0/180deg phase selection for each bands.

Oil capacitors upgrade for mid and hi bands, silver capacitors upgrade for lo and sub bands.

All 3D point-to-point and component-to-component hand wiring with shortest distance, no unnecessary long bundle cabling just for the sake of presentation (another move trying to impress the brainwashed vast public) which end up causing poor channel separation and loss of micro-dynamics and transparency of the sound stage.
