HATT-MkIII-C



The HATT Mk-III-C – The popular mini-monitor taken a level higher

Based on the HATT-MkIII cabinet and woofer, the original Seas tweeter has been replaced by a ceramic version. This resulted in a total revision of the crossover and a new damping material plan but the end result was certainly worth the effort.



  The HATT-MkIII-C’s next to the original HATT-MkI.



The tweeter

The Thiel & Partner C2-12/6 is a Ferro fluid filled tweeter with a 25 mm lightweight concave ceramic dome. Designed for 3-way systems or small, low-output 2-way designs. Very high resolution and very good dispersion up to 42 kHz. Low resonance frequency allows first order filtering and a crossover frequency as low as 2 kHz. The ultra hard ceramic dome material moves like a piston well above the audible frequency band and the high internal sound velocity features very low distortion and virtually no coloration.







The mid-woofer

The Seas L12RCYP-H1207.  It’s a 4.5" mini woofer with a stiff and stable injection moulded metal chassis. The stiff, yet light aluminium cone and the low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion associated with soft cones. On the other hand, the cone break-up modes at higher frequencies call for special attention in the crossover design work. The high temperature voice coil wound on an aluminium voice coil former gives high power handling capacity. A black plastic bullet shaped phase plug reduces compression due to temperature variations in the voice coil, avoids resonance problems which would occur in the volume between the dust cap and the pole piece and increases the long term power handling capacity. An extra large magnet provides high efficiency and low Q. The unit may be used in very small two-way ported systems producing a relatively deep bass and a clean, neutral midrange.







The cabinet

All walls are made of 22mm MDF, just the standard 6 planks. No difficult matrix constructions seeing as they are so small. The cabinets shown on the pictures have additional wooden side-panels for the looks. The edges of the cabinet are routed with 10mm's radius for looks and to remove the sharp edges that would cause baffle diffraction problems – the drawing shows the minimum required: a 45 degree angle on the vertical edges of the front baffle. The reflex port is made from 40mm thick-walled PVC sewer pipe with a length of 130mm.



A higher resolution drawing is available on request.



The inside of all the walls except the baffle are covered with lead bitumen sheets and heavy-duty carpet tiles. The carpet tiles have a nice heavy backing that adds mass to the enclosure. No other damping material at all is used. This results in a good bass weight considering the size of the woofer and cabinet with good dynamic capabilities. The internal volume is only 4,5 litres and the bass-reflex port is tuned to 62Hz giving sufficient output down to about 55Hz.



The crossover network

It uses a combination of a first and a second-order series-filter. First order on the tweeter and second order on the woofer due to the extra inductor L2 before the woofer – this compensates the baffle-step. The extra components are the resistors to tame the tweeter and a Zobel network to compensate the inductive rise of the woofers voice-coil. Parallel across the woofer is an LCR-network that cuts out the resonance due to cone break-up and gives a smooth roll-off above the crossover point with the tweeter. The critical inductors are air core type using large gauge copper foil for better imaging and detail compared to standard air-cores. The capacitors use high-grade metalled polypropylene foil and the thick film resistors have minimum tolerance. The tweeter is connected with reversed polarity.







Filter components:

L1 = 0,68 mH Copper Foil 12-AWG air-core inductor, R = 0,15 ohms (tolerance max 2%)

L2 = 0,82 mH Copper Foil 12-AWG air-core inductor, R = 0,17 ohms (tolerance max 2%)

Lz1 = 0,22 mH air-core inductor - 0,71mm wire baked varnish, R = 0,39 ohms (tolerance max 2%)

C1 = 10uF MKP polypropylene foil capacitor – Clarity Cap SA or better (tolerance max 2%)

C2 = 3,9uF MKP polypropylene foil capacitor – Clarity Cap SA or equivalent (tolerance max 2%)

Cz1 = 1,5uF MKP polypropylene foil capacitor – Clarity Cap SA or equivalent (tolerance max 2%)

R1 = 3,3 ohms (3x 10 ohms parallel), Caddock MP930 thick film resistor (tolerance 1%)

R2 = 10 ohms, Caddock MP930 thick film resistor (tolerance 1%)

R3 = 10 ohms, Caddock MP930 thick film resistor (tolerance 1%)

R4 = 1,5 ohms, 5 watts MOX (tolerance 5%)



* Bypass all capacitors with a 0,01mF Styroflex or Vishay MKP1837 capacitor

** The Caddock MP930 should be mounted on a heat-sink for maximum power handling.





The final (external) crossover.



Measurements







Output level 200-20.000Hz – horizontal division 5dB. Good linearity within +/- 1,5dB, the drop towards the lower end is due to the measurement being done in free-air (so no boundary re-enforcement) – typical in room response is down to about 60Hz. Crossover point at 2 kHz.







Impedance plot 20-20.000Hz, horizontal division 1 ohms, and range 0-24 ohms. Note the port tuning frequency just above 60Hz. The impedance peak just below the crossover point can be compensated with an LCR-network parallel across the input terminals. The values should be 1,5mH / 11uF / 18 ohms.



Sound

Straight out of the box, these hard-cone drivers sound cold, closed-in and lack bass and dynamics. Give them at least about four to six weeks of normal listening before they open up. The burn-in period can be shortened by feeding them decent levels of pink noise or FM radio inter-station noise. After this burn-in period The HATT-MkIII-C can best be described as a very coherent, clean and smooth sounding loudspeaker. The bass is full-bodied considering the size, varying the distance to a rear-wall can be used to balance the bass-weight to personal taste. Completely free-standing they can be a little lean but I found the best results with them between 30-50cm from the rear-wall. The midrange is clear and flows seamless into the clear and clam treble. Micro-detailing is very good as is spatial information. The Accuton tweeter costs more than the Seas tweeter from the HATT-MkIII but in my ears, is really worth the extra investment. The high-grade crossover components bring out the quality of this little speaker very nicely.

Humble Statement

Humble Statement, or how to build a no compromise loudspeaker again

Eight years have passed since I designed the Andromeda loudspeaker. Time to design and build a loudspeaker that could serve as a new reference for years to come. Cabinet construction had to be at least as solid as the Andromeda, driver choice the best available for today’s DIY market and the crossover true three course haute-cuisine.



The tweeter

The Thiel & Partner / Accuton C30N-6-24 is a high efficiency, Ferro fluid filled tweeter with a 30 mm lightweight concave ceramic dome using the smaller size front plate. It has a new 6 mm under hung neodymium magnet system. Very high resolution and very good dispersion. Low resonance frequency allows first order filtering and a crossover frequency as low as 2 kHz. The ultra hard ceramic dome material moves like a piston well above the audible frequency band and the high internal sound velocity features extremely low distortion even at high volume combined with virtually no coloration.

The tweeter alternative

The Focal Utopia TBe is a high efficiency tweeter with a 25 mm lightweight pure beryllium inverted dome. Beryllium's density is 2.5 times lower than titanium and 1.5 times lower than aluminium while its rigidity is 3 times higher than titanium and 5 times superior to aluminium. Which means that for a dome of identical mass, a beryllium version is 7 times more rigid than one made of titanium or aluminium - which have similar rigidity for a given mass. Moreover, the velocity of sound in a beryllium dome is 3 times faster than a titanium version and 2.5 times faster than aluminium. However, the manufacturing of beryllium remains very difficult. Beryllium is an excellent high-tech metal - the only metal able to scratch glass - it is only used in strategic applications in the aeronautical and military industries and consequently, its unique characteristics make it extraordinarily expensive, much more than gold and nearly 100 times that of titanium. And the result is an outstandingly detailed loudspeaker which extends to nearly 40 KHz while maintaining a perfect impulse response.

The midrange

The Thiel & Partner / Accuton C173N-T6-90 is a midrange driver with a light weight concave ceramic cone with a penetrated membrane for resonance damping, double roll fabric surround and a large 55mm titanium voice coil former in a new 173 mm vented basket. The 14mm under hung Neodymium magnet system gives extremely low distortion and very high efficiency of 93 dB. Designed for large 3-way systems as a dedicated midrange driver. Very high resolution and very good dispersion up to 2500Hz. Low resonance frequency allows first order filtering and a crossover frequency as low as 200 Hz – I even ran it without a high pass filter in initial tests! The ultra hard ceramic dome material moves like a piston and the high internal sound velocity features virtually no coloration.

The cabinet inside and out

The raw cabinets were constructed by Dennis Grootaers from The Netherlands. These cabinets are extremely complex and time-consuming to build and are not something for a first-time woodworking project. Be prepared to spend many hours in constructing, sanding and finishing these two “boxes”. The top half is made from CNC-milled mdf panels, stacked to form the tweeter and midrange section of the cabinet. The inside has an irregular shape to cancel standing waves; the outside is curved to give the large cabinet a more friendly appeal. The cabinet's swept-back profile better time-aligns the drivers, and makes the speaker more stable by shifting the centre of gravity rearward.  The lower section of the cabinet containing both woofers is more traditional in construction and is made from thick mdf panels with extensive internal bracing. Covering the front of the whole cabinet is the 30mm thick baffle made from solid American walnut wood. The baffle has large rounded-off edges to minimize baffle edge diffraction and has a tapered contour to keep the baffle area as small as possible, minimizing the frontal area and therefore also the amount of reflective surface. Thin routed channels were made to accentuate the vertical direction, making the whole speaker look more slender in appearance. The American walnut baffle has a semi-matt oiled finish, the main mdf section of the cabinet is spray painted in Audi Lava Grey metallic. All this mdf, real-wood, glue, oil and paint results in extremely dead and heavy enclosures weighing about 80kg each. You will need at least two people to lift them! Here are a few photos to explain things a little better:

A higher resolution drawing is available on request. Note that the drawing should be seen as “sketch”. Some improvisation skills of the builder are called for – this is not a beginners project!
