Monitor loudspeaker by Tony Gee of The Netherlands.

BL ACK BOX

Design Goals
The Black Box was designed to be a precision monitor speaker that could produce deep bass from a relatively small cabinet and have the detail and neutrality of a studio monitor. As I have stated in the past, for me natural effortless bass is only possible with lots of cone area in the low frequency range. When using a single driver, 10 inches is about the smallest size you can get away with. Downside of these large woofers is that they need a lot of air behind them to be able to produce deep bass. This speaker shows you a way to get around that problem and still maintain a full-bodied sound. The deep-bass-small-cabinet concept is based on the principle of mounting a large woofer in a small closed box, purposely creating a slight hump in the output level and then attening the response by putting a capacitor directly in series with the woofer. When dimensioned correctly, the capacitor will react with the impedance peak of the woofer at resonance. At and just above fc it will raise the impedance, therefore letting less current go to the woofer. Just below fc it will lower the impedance slightly, there drawing a little extra current from the amplier, thus increasing the output level. So the end result is an enclosure much smaller than the equivalent version without a high-pass capacitor and at the same time having a lower -3dB point in the bass! This concept isnt new and to my knowledge has been used in many commercial designs since the late 1970s. Users of this principle (to name just a couple) are Isophon and KEF. Back in the mid 1980s KEF even had several DIY kits available with capacitors in series with the woofer. This Constructor Series CS9 for example had the famous B-300B bextrene woofer with 450uF in its direct signal path. Finally another advantage of this capacitor is that it creates a subsonic lter protecting the woofer from infra-sonic frequencies and therefore giving the woofer a little more dynamic headroom and greater power-handling.
1-1/8 tweeter to improve power-handling and maintain a coherent source rather than use a smaller 3/4 dome tweeter that has to be crossed higher and therefore stretching the radiation point at high frequencies.

Black Box

Driver Selection
The only criteria for a woofer to work according to this principle is that the driver must have a low resonance frequency fs (below 30Hz) and a high Q-factor Qts (above 0,40). Basically these type of woofers are designed for use in closed boxes or large bass-reex enclosures. Browsing around the web, I came across the Dayton RS270S-8. This 10-inch woofer is big enough, has a resonance frequency of 27Hz and a Qts of 0,41. The Q-factor will be raised slightly when there is extra resistance in the signal-path by means of the resistance of connectors and wiring and the Rdc of the inductors, in this case about 0,5 ohms. The Dayton RS270S runs very well up into the midrange, the stiff black anodised aluminium cone showing a very short decay time in the usable area. For a matching pure midrange driver I chose the Dayton RS52AN-8 which is a 2 black anodised aluminium dome-midrange because of its good on-axis and off-axis radiation pattern. Furthermore the moving mass is much lower than that of a conventional cone midrange, with speed and micro-detail in mind, a positive point. The logical tweeter is the Dayton RS28A-4 that also uses a black anodised aluminium dome. I chose a relatively large

Enclosure Design

Now for the implementation of the woofer/capacitor concept. The cabinet volume for the woofer should be calculated based on a closed box with a Qtc of about 1,0. In this case it results in a nett volume of 24 litres, very small for a 10-inch woofer considering that a standard maximally at Butterworth alignment with a Qtc of 0,707 would have lead to an enclosure about 3 times as large! The midrange and tweeter come with their own sealed rear volumes so they dont need any extra air from the cabinet. All they need, practically speaking, is a bafe to be mounted on. The size of the bafe is chosen as compact as possible - the minimum width is determined by the width of the woofer, the minimum height is determined by the space required for mounting the three drivers in a vertical line as close as possible above one another. The spare space behind the midrange and tweeter I reserved for the crossover, kept well away from the high pressure inside the woofer volume.

Malibu Series

Butyl rubber surrounds are superior to foam in two important ways. First, the butyl rubber resists moisture and will not dry rot, providing years of service. Second, the rubber surround, due to its superior damping characteristics, will greatly reduce cone break up and ensure low distortion. These woofers are ideal for replacing and upgrading old, worn out drivers. They all feature a polypropylene cone, vented pole piece, foam gasket, soft poly dust cap, and stamped steel frame.
