The DIY Speaker Builders Reference: Articles.

       The following articles have been written as a guide to working with components and materials which are commonly, or not so commonly used in the construction of DIY Loudspeakers. It is not an exhaustive list but is based upon the hands- on experiences of QTA Systems in building cabinets and cases. The notes also draw attention to the pitfalls which can occur when performing certain assembly techniques.

(1)    BITUMASTIC: Bitumastic damping is often used in Loudspeaker cabinets and is a heavy material well suited to providing panel damping and resonance suppression. Bitumastic Damping Bitumastic Damping Sheet

(2)    NUTS & BOLTS: There are literally hundreds of screw type fittings available in a wide number of materials. We look here at a small range sensibly suited to the DIY Loudspeaker Builder. Nuts & Bolts

Cap Head Bolt

(3)    DAMPING MATERIALS: The application of damping materials to a loudspeaker cabinet can provide a considerable improvement to the acoustic properties / sound. The topic is complicated and we skirt around the heavy detail to give you the bottom line.Damping Materials

Herdwick Sheeps Wool

(4)    SPEAKER GASKETS: To work effectively Speaker Cabinets require an airtight seal between the driver and the cabinet. We show you here what materials to use and how to construct airtight seals between driver and cab. Gaskets

(5)    RAWLNUTS: In building dipole designs it is important to reduce / isolate Base driver vibration from the rest of the cabinet. The technique explained here provides some thoughts and ideas to achieve this goal. Rawlnuts

(6)    SORBOTHANE: A relatively new material with the ability to absorb vibrational energy and dissipate same into heat. Used in high tech footwear, electronic data systems, to damp heavy machinery vibration and as a high end damping medium for Loudspeakers.Sorbothane Hemispheres

(7)    LOUDSPEAKER SPIKES: There are many different types and styles of loudspeaker spikes. We take the lid of the pot and advise the do's and don't's of retro-fitting your own.Speaker Spikes

(8)    TURRET TAGS: Want to make your own crossovers, from prototype to something a bit mechanically better. We give you some hits and tips on how to do that job just a little bit better.Turret-Tags
