Hello all.
Here is a new design I want to contribute. I call it TB4D (Tangband 4'' double). Its cheap and simple to make. It is rather small and 90dB sensitive.
The drivers are Tangband W4-657SC (2 per speaker) and Tangband 28-847S for tweeter. They do offer great quality at the price (139 EURO for all 6).
I kept it simple. All drivers running the centre line, tweeter in the middle. Simplest crossover possible but nothing left to chance. Very good lobe and tight 50Hz to 20kHz monitor like response. Sounds alive but never irritating. Bass is great for the size. Transients clear as a bell. 3D imaging.
Look at the cabinet photo and you will see the dimensions too. Keep in mind that the reflex slot is mirror positioned for the pair to the outside of each speaker.
It is not veneered yet but I will rather choose a dark finish to highlight the magnesium cones. I eased the reflex slot lips as well as the edges of the box face. I used wool felt pads for damping. All drivers flanges are inset.
I also designed for a listening axis higher than the tweeter centre. So if you make a stand for TB4D it will not need to be rather imposing when the axis is targeting your sitted ear hight.
I used Visaton MKP caps and a simple 1mm wire air coil. No biwiring. If you end up liking it as much as I do and want to experiment with expensive parts, I feel it will respond. There are very few crossover parts anyway.
TB4D has potential for very good systems. Just give it 2 days to break in.
