  • Here's my Well Tempered rebuild

    Here's my Well Tempered rebuild

    Here's my Well Tempered Simplex rebuild. We've renamed it the WT "Complex."

    Bought it as just a plinth with motor and bearing off eBay, adapted WTRP bearing, spindle and platter purchased off eBay to it by building a lower base. Moved the squash ball feet to the lower base, bought an AC adapter, built the arm and arm suspension, counterweight, arm rest and designed 3 parts that a friend printed 3D for me. Originally tried to adapt the 5-pin DIN plug to the plinth that WT Lab...

  • Noobster build with Piano Black How To

    Noobster build with Piano Black How To

    For the piano black finish.....get ready. This is quite a bit of work. Made MUCH easier with the right tools...but is a bit of bear regardless. Total time took over a month for me including all my orders/lessons learned/and actual finishing. With a second go-round, I bet I could do it over 3-4 weeks only working on weekends. Biggest part is drying time. Figure a day for final sanding/polishing/installing components for the pair.

    I tried to do it the poor man's way, but it was exhausting...

  • Magnepan 1.7 Review

    Magnepan 1.7 Review

    Having been an extremely frugal music listener-mainly due to financial reasons-it has been difficult throughout the years to satisfy my want of good sound. I've typically either bought used gear, waited for something to pop up on the interweb, or used various employee discounts to buy the next piece of the audio nirvana pie. Thus it was outside my typical comfort zone when I purchased a brand new pair of Magnepan 1.7s two months ago. For that story, see this thread:

  • New Pioneer Elite FD62 Blu Ray Player

    New Pioneer Elite FD62 Blu Ray Player

    Today, I received my new Pioneer Elite FD62 blu Ray player. The build quality is in fact, very average, as honestly I expected for a retail $400.00 player. It's very lightweight and has a small footprint. Image quality seems pretty good out of the box, I have not done any adjustments. I have watched Knight and Day partially on projector, and partially on my 59" plasma. Both seemed reasonably good. There was some pixelization visible on both displays with this player. Some of this could be...

  • Exploring Common DIY Terminology - Suspension
    by technodanvan
    Suspension

    The suspension refers to the mechanical system that provides support and control for the diaphragm (cone/dome) and voice coil within the driver's magnetic structure. The suspension is an important component that allows the diaphragm to move back and forth in response to the electrical audio signal while maintaining stability and linearity. The suspension system typically consists of two key components: the spider and the surround.

  • Exploring Common DIY Terminology - Surround
    by technodanvan
    Surround

    In the context of loudspeaker drivers, the surround, also known as the "speaker surround" or "suspension surround," is a component that plays an important role in the driver's suspension system. The surround is typically a flexible ring or membrane that connects the outer edge of the loudspeaker diaphragm (cone/dome) to the driver's frame (basket). The primary function of the surround is to provide a compliant and flexible suspension for the diaphragm, allowing...

    Spider

    In the context of loudspeaker drivers, the spider refers to a component that plays an important role in the suspension system of the driver. The spider is an essential part of the driver's overall mechanical structure, helping to center and control the movement of the voice coil and diaphragm within the magnetic gap. The spider is typically located between the voice coil and the frame (basket) of the loudspeaker driver. It is made of a flexible material, such as cloth or treated...

  • Exploring Common DIY Terminology - Soundstage
    by technodanvan
    Soundstage

    Soundstage refers to the perceived spatial placement and localization of sound sources in a recording. It describes the three-dimensional presentation of audio, making it seem as if the sound is originating from specific locations within the listening environment, rather than coming directly from the loudspeakers. When a recording and playback system is capable of creating a convincing soundstage, listeners can experience a more immersive and realistic audio experience. The...

  • Exploring Common DIY Terminology - SINAD
    by technodanvan
    SINAD (Signal to Noise and Distortion ratio)

    While not directly applicable to loudspeaker design, SINAD is a term in common use and is a valuable tool when comparing electronic equipment to match with your speakers. It can also be used when deciding what equipment you'd like to use for your measurement setup. SINAD stands for "Signal-to-Noise and Distortion ratio." It is a metric used to quantify the audio quality of electronic devices, particularly audio equipment like amplifiers...

  • Exploring Common DIY Terminology - Signal-to-Noise Ratio (SNR)
    by technodanvan
    Signal-to-Noise Ratio (SNR)

    The signal-to-noise ratio (SNR) is an important parameter that helps evaluate the performance and quality of the audio output. In the context of audio, SNR refers specifically to the ratio of the desired audio signal (the sound produced by the loudspeaker driver) to the background noise generated by the speaker itself or the overall system.

    The formula to calculate SNR in decibels is:

    SNR (dB) = 10⋅log⁡10(PowerSignal/PowerNoise)
