  • Some Peerless India drivers: whatever I could find in my ramblings


  • The Asawari family: floorstander MTM speakers with 6.5" midbass drivers and passive 2-way crossovers:
    • Early days of DIY: a personal history of my experiments with DIY audio
    • The Asawari: Peerless India 6.5" Kevlar drivers and Peerless India T26 tweeters. Full plywood construction with superb inert enclosure due to EVA sheet linings and good bracing, without any MDF. My first serious DIY speaker design and construction, circa 2006
    • The Asawari Mark II: floorstander MTM speakers with 6.5" Peerless India Kevlar cone midbass drivers and North Creek D25 silk dome tweeters
    • The Asawari Mark III: floorstander MTM with 6.5" Vifa P17 drivers and North Creek D25 tweeters fitted into cabinets designed for the Asawari Mark II. The Vifa P17 were chosen because the Peerless India Kevlar drivers used for the Mark II were no longer available by the time it was time to put the system together, so the same Mark II was used with the Vifa P17. Not documented here, since the drivers are obsolete anyway. Better Asawaris were made later.

    • The Asawari Mark V: Dayton RS180 6.5" aluminium cone midbass drivers, Seas 27TDFC fabric dome tweeters, crossed over at about 1.5KHz 6th order
    • The Asawari Mark VI: Dayton RS180P 6.5" paper-mix cone midbadd drivers, SB Acoustics soft dome tweeter, crossed over at about 1.5KHz 6th order
  • The Darbari: floorstander two-box TMW active design with Dayton RS270 10" woofer, Dayton RS150 6" midbass used as midrange, and Peerless HDS dome tweeter, driven by MiniDSP 4x10HD and six channels of amplification
