InConcert Duke

Description
The InConcert Duke!

This is THE smaller, great Powerful brother of the previously successfully built Tangen's InConcert Miles.
A wonderfully robust, solid and modularly designed sleek combination.
The difference is that it has 12" basses and the same plate tweeter, but without the horn.
This is effortless, very dynamic, powerful and tight.

An unprecedented Superior High Efficiency with a Very Broad and In-Depth Reach!....
A fantastic complete concert hall and live recording in your listening room!

This really is a great, powerful display with everything you need!
Listening to this combination will never tire you, rather fascinate you!

Equipped with high-quality, beautiful professional drivers from Beyma.
No less than 4x 12 inch 12P1000Nd bass to caress your living room and ears with the unprecedented quiet and deeply controlled, tight bass.
This is generated by the large surface area in combination with the small displacement of the cones, which also results in minimal deformation.
In combination with the great Ribbon Tweeter, the TPL-150B from Beyma for ear-pleasing and detailed highs.
Everything superior, very beautifully filtered and in proportion!

Superior drivers positioned in very well built and designed housings in accordance with the original design, but in their own separate jacket.
A great combination to completely fill your listening room with the most beautiful sounds and with the highest efficiency.
This combination cannot be beaten in terms of control with the least power and the high efficiency that is reproduced.

Truly everything comes and goes with the minimum of ease.

A superior PA combination with HIFI playback in your listening room!
Also very ideal for a tube enthusiast!

Built with great care and very solidly.

Very beautiful Beyma 12P1000Nd with its beautiful large dust cover and ribbed cone, a feast for the eyes.
The TPL150B too, of course again, just like with the InConcert Miles, in a separate room to completely exclude any unwanted influences from the bass room.

It is a 2.5-way construction, with the upper bass playing the full tones (unfiltered) while the lower bass has a partial filter (LP).

Also plays very well, very powerful and dynamic.
The depth and efficiency of the bass is comparable to that of the Miles.
This is done by increasing the capacity from 77 liters gross to 100 liters net and ideally tuning the best ports, 2x Jetset 100.

The Duke plate tweeter works in slightly better working conditions up to 1200 Hz than that of the Miles (up to 900 Hz).
This Duke will have a great game with the Miles.

Cabinets are solidly made in black and clear HD MDF in combination with solid oak.

Damping entirely 42mm Pritex except the baffle in combination with 8mm self-adhesive felt.
