Diaphragm (Cone) - paper cone made with the best beating degree and freeness ratio (°SR), which is one of the main factors affecting the driver characteristic. "°SR" is calculated in terms of the Schopper-Riegler (SR) value, which determines the rate of drainage of a dilute pulp. The SR value is the inverse of the volume of water collected divided by 10. The rate of drainage is related to the work done on the fibre during beating and refining. It is a very important index for paper manufacturing.

Dome (Dust Cap) - its curve is being calculated curve for perfect integration with Ologe's diaphragm. It is also a part of the acoustic design of the driver by radiating/suppressing high frequency energy. A staple of audiophile-grade speakers, Ologe's special designed dust cap features low distortion, flat frequency response and smooth acoustic dispersion.

Suspension (surrounds rubber) - with the accurate mass, it can prevent the impart energy to go back to the cone, the problem of audible signal that is often referred to as edge yowl. It serves to terminate or dissipate the waves or vibrations that travel up the cone towards it periphery.

Voice Coil - the heart of the speaker, it gets energized by amplifier output signal and moves the cone in and out to produce audible sound. To attain a solid soundstage the gap/space between voice coil and centre pole/front plate hole must be less than 1/10,000 inch. In any case, there should not be much room for the voice coil to over-expand or deform much.

Spider - made of a bakelized fabric with accurate no. of corrugations. Our spider is designed to be at twice more as wide as the corrugations in the surround of the cone it is used with. That's why our driver can produce prodigious power of sound without any problem, even over its limit.

Waveguide (face plate) - die casting aluminum with accurate calculated curve, it can produce the widest axis sonic effect with Ologe talior-made tweeter driver.
