How to put 10" Audio Nirvana drivers in 8" speakers designed by Decware?

hebrer · 16th August 2010, 08:59 PM

I am currently building my second pair of speakers (first was Metronomes with Fostex 127eN, with quite satisfying results) and I face the following dilemma.

I have bought a pair of 10" Audio Nirvana cast frame drivers for which I need to build a fitting enclosure. I am tempted not to build the manufacturer-recommended bass reflex speakers but rather to try the HDT enclosures designed by Decware. But the plans I purchased from Decware are for 8" Fostex drivers.

What do you think of modifying the size of the HDT enclosures to fit the 10" AN drivers? Anybody tried something similar? What principles should be applied when "enlarging" enclosure so as not mess up the acoustics originally finetuned for different size?

Thanks for your opinions.

same answer as at Audio Circles forum:

in short, contact the designer directly when contemplating any proposed changes of driver(s) for which an enclosure (other than a simple sealed box) is optimized

Hi,

The modifying principles are based on the relative parameters of
the two drivers in question, but if any of the details of the design
are based on quirks of the original driver they will not translate.

Depending on the parameters of the two drivers it may be easy
to suggest a relevant transform or impossible to say sensibly.

rgds, sreten.
