Ken Freeman & The Birth Of String Synthesis. People + Opinion : Artists / Engineers / Producers / Programmers Ken Freeman couldn't afford a Mellotron to play his string parts, so he invented a new kind of electronic instrument.
But though the world would eventually embrace string synthesizers with a passion, he never got the credit he deserved. Gordon Reid When I was but a wee lad in the late 1960s, I was besotted with... umm, something. I didn't have the faintest idea what it was, but I could instantly recognise the weird sounds that I loved pervading the music that my parents hated: Traffic's 'Hole In My Shoe', Pink Floyd's 'See Emily Play', The Move's 'Blackberry Way'. What they didn't realise (and, to be honest, neither did I) was that I was listening to recordings of three little old ladies playing their violins in someone's bedroom in 1952.

Preamplifier 2012 (3) Preamplifier 2012 (2) Elliott Sound Products - The Audio Pages (Main Index) Pages Last Updated March 2014 Welcome to ESP, the home of DIY audio articles, projects and shortform kits.
Audio is a wonderful hobby, and with DIY there is a huge scope to get the very best performance for a lot less money than otherwise. DIY audio is fun and educational, and by building your own audio equipment, you get to learn electronics as well as build equipment that would cost a great deal more in the shops. ESP is committed to providing high quality projects that are known to work, printed circuit boards (PCBs) for the most popular projects, and to assist you if necessary to complete or debug your project. There is a very wide range of power amplifiers, preamps, guitar/ bass amplifiers, studio equipment, effects, and other projects to build, including loudspeakers, subwoofers, and many others.

A subwoofer for use with multimedia loudspeaker systems Published in issue 318, February 2003 As with most small enclosures, the bass response of the active 2-way loudspeakers described last month has its limits.
The compact subwoofer described here will therefore be a welcome addition for most enthusiasts. With its adjustable filter this subwoofer will also work very well with other small (satellite) speakers.As a rough guide the bass response of loudspeakers tends to improve in proportion to their dimensions. This is not completely true, since there are a few tricks that can be used to get a reasonable bass response from a relatively small enclosure.
