    Expensive power cables...

    I'm thinking of building a power cable for my receiver out of this stuff. Any advice? This will probably end up quite expensive, so I'd like to get it right first time. :D

    Cheapest digital solution - recommendations?

    OK, here's what I want from a PCI soundcard: * Optical or coaxial S/PDIF output * True 44.1kHz without sample rate conversion * DTS and DD passthrough I've read lots of other threads here, but nothing seems to answer this directly. I've seen the Abit UA-11 USB device which looks...

    Two drivers in one enclosure?

    What happens to the effective T/S parameters of a pair of identical drivers in a single enclosure? I'm not talking isobaric alignment, where the Vas is halved. I'd guess the Vas of the pair is double the Vas of a single driver, but can anyone confirm? And for the more general line array case...

    Cheapest soundcard with true 44.1 SPDIF out?

    I'm looking to integrate my PC into my AV system, and use it as a CD jukebox. I plan to rip all my CDs using a lossless compressor like Monkey's Audio or LPAC to maintain maximum quality, and use a soundcard's SPDIF output to feed my receiver. As this will be purely digital and I'm not (at...

    First DIY sub - initial rendering

    I'm planning a small-ish electronically-assisted sealed sub for my small HT setup. Priorities are: * High-quality response down to 20Hz * Compact size (10" or 12" driver max) * Low cost * Very high WAF I am not interested in high SPLs, and will be driving it from a BK Electronics...

    Subwoofer variable phase controls?

    Those variable phase controls on some subwoofers - are they actually just a delay stage? I can see how the phase of a single note can be varied whilst retaining the information, but changing the phase of a complex, asymmetric music signal doesn't seem possible to my limited brainpower. The...

    Marantz SR-4200 and hum - anyone?

    I have a Marantz SR4200 and am very impressed with it, as my first excursion into the home cinema experience. Lovely sound, acceptable looks, good features. However, the unit itself suffers from a very slight transformer hum, which is really only audible with the unit powered up with no input...

    Port length to diameter ratio?

    I'm considering a sub project at the moment. I don't yet want to get bogged down in a detailed discussion of what I'm trying to do until I know it's feasible - but I will need to tune a relatively small box (1.3 cu ft) to a very low frequency (22Hz). For a 3" diameter port, the port length...

    Bass management: Marantz strategy?

    I've just taken my first tentative steps into home cinema with the purchase of a Marantz SR4200 amp - very impressed. :D My main speakers are old Wharfedale Diamond 4s, and until I get around to building a dedicated subwoofer, I'm using the aux in of my Clavinova which works surprisingly well...
