As a newcomer to speaker building, I am grateful for all this information, but I must say that the more I learn, the more confused I become! I am now intrigued with the possibilities of OB design. Given that I expected to utilise a subwoofer anyway. What is the highest frequency that I could crossover at without losing integration of the overall sound? My reading suggests around 130Hz - could it be higher if I use 2 subwoofers. I would wish to use an active crossover, so my 2a3 amp would supply the main component of the music, and I would use a high power transistor / chip based amp (ie. a chip based pcb kit - Maplin or similar) for the subwoofers. Can anyone point me to a very good crossover? --- The valve amp has 2 or 3 inductors -- o/p, interstage, and optional switched transformer attenuators on the input. How would the phase -shift difference between the amplifiers affect the integration? Is there maybe a complete subwoofer amp that contains crossover, amp, and phase-shift ajustment?

Hi-Fi Audio Drivers (Speakers and Tweeters)
These are some of the drivers that we have had the opportunity to try out over the years. The pages contain information about the drivers (transducers) including photographs, history and background information, driver specifications and links to DIY speaker enclosure designs. The Thiele/Small Parameters have been measured for many of the drivers using the Dayton Audio Test System (DATS). Questions and discussion about loudspeaker drivers and building is welcome in the DIY Loudspeaker and Subwoofer forum.

Fostex 168 Sigma full range driver – older style with whizzer. Since then, I began purchasing fullrange drivers that were being discussed online. People loved the very inexpensive Radio Shack drivers. I bought several but primarily recall the 40-1197 and 40-1354 as my favorites. Fostex seemed to be an upgrade and I purchased the 127e, 168z.
