    Receivers and Active EQ

    Hi, We recently bought an ONKYO TX-SR701 receiver and a Pioneer DV-667As for my dad who has a pair of BOSE 901VI. Dad would like to use the 901s as the front surround channels, unfortunately the speaker's active EQ is proving to be a challenge to insert between the signal path. At the...

    For those interested in flared ports...

    I've typed up a page about tube and flared vents. It might be of interest to those (including myself) who have no source of quality flared vents such as the FP kits from Adire Audio. The page might help builders spin/rout/carve/sand their own flared vents. I'll write a small program for the...

    minor software update

    Link to page Couldn't sleep, so I made a minor change in my measurement unit conversion utility. It used to start calculating values when the user exits an edit box (like uSoft Excel), now the program is set to calculate when the ENTER key is pressed (like uSoft Excel ;-). Hope you find it...

    Great DVD for testing your subwoofer(s)

    hello everyone! I rented Dungeons & Dragons DTS/DD dvd to try out my recently completed Shiva sub and boy-oh-boy I wasn't disappointed! Tonnes of BASS (from both my new sub and the movie); VERY nice CG special effects! Good story, maybe even better than SW: Ep.1 (disagree?) :) When did...

    MDF faq

    Hi, It is settled -- my first Shiva sub will be of box type :) At AU$161 for a 24" by 4m tube and AU$60 to have it delivered, Sonotube is just too costly for me at the moment (when I only need a 24" by 21" tube) Depending on the size of ready-made ports, I'm looking at a box that is 21"...

    DVD player and CD-Rs

    Hi, Like most SONY DVD player owners, I am equally-frustrated that these units refuse to play CD-R disks However, I haven't heard anyone try "Audio CD-R" disks. Standalone CD-R recorders refuse to work if an ordinary blank CD-R is used. Apparently, standalone CD recorders look for some...

    How is End-Correction calculated?

    Hi, Calculating end-correction(s) for a simple cylindrical port is quite straight forward -- all that is needed to be known is if the port is flanged/free; in free-air or in a large enclosure. What about for a cylidrical port which is terminated with flares -- flares with significant flare...
