Here is my parameter file for this driver for WinISD Pro ver 0.50a7

 

As of 8th August 2007, the Venom range of drivers has been discontinued.

 

Suggested designs

Jaycar Design 33.29 litre sealed
My Design 70 litre box + filter tuning freq 27hz One 102mm port 404mm long

 

SPL

Both designs require 150watts. Jaycar has removed the 150w / zero boost amp from its lineup, so I have modelled using the 240watt amp with 6dB boost @ 35hz, utilising 150w

Jaycar sealed design in red - would perform better without the boost circuit - as shown here in purple

My ported in green - I was unable to get a flatter response than this because of excursion problems above the tuning frequency

 

 

Cone excursion

Jaycars design is fine for excursion.

My design requires high-pass filter (linkwitz-riley 24dB/octave, design frequency 18hz) to control excursion below the tuning frequency

 

 

Port air velocity

A single port is sufficient

Port flares would be required - see the note at the bottom of this page

 

This driver runs out of excursion too easily to get a ported design that performs well. The best way to use this driver would be to use Jaycar's sealed design if you can still get the 150w / zero boost amplifier .Note that Altronics still makes one

 

Port Flares - calculated with Flare-it

I would recommend a 13mm routed flare.

The intake could be flange mounted with a 13mm routed flare or you could fit a donut ring .

Depending on the flaring options, you'll need to adjust the physical length so that the effective length is as shown above. The port flares page has a section on calculating effective length as well as some information on availability of commercial flares.
