Pookus Posted March 16, 2009 Share Posted March 16, 2009 I love this speaker! I have it in an old cab. Just wondered what the optimum cabinet dimensions were for this speaker. I'm thinking of getting another. Thanks Quote Link to comment Share on other sites More sharing options...
stevie Posted March 17, 2009 Share Posted March 17, 2009 I've had a very quick look and the speaker seems to be happy in anything between 35 and 60 litres internal volume. The bigger the cab, the more bass. Quote Link to comment Share on other sites More sharing options...
Alien Posted March 17, 2009 Share Posted March 17, 2009 It optimises into a vented box of 107 litres, which is enormous for a 1x12. I'd personally put it in a box of about 55 litres tuned to 60 Hz, which gives an f3 of 57 Hz and a slight hump in the 70-150 Hz range for a bit of low mid punch.

Thanks :)[/quote] No hi-fi nut would ever build a loudspeaker with 2 internal dimensions the same. So no cubes. Try (external) width the same as a rack-case, with internals at 52cm high x 24cm deep. That will give a slight excess over 55litres and allow for bracing etc. Good luck. Balcro Quote Link to comment Share on other sites More sharing options...

Use 2 x 70mm ports, each 125mm long. Or to tune to 60Hz use 35mm long ports. Quote Link to comment Share on other sites More sharing options...
alexclaber Posted March 17, 2009 Share Posted March 17, 2009 I haven't got round to modelling it but as Qts is high you should be able to tune it low as Stevie suggests to prevent over-excursion below the tuning frequency without losing bass sensitivity. It's certainly a far better driver than the comically misapplied Orange label 'bass' models which have hardly any Xmax and really high Fs - weird!

Even some professionally built cabs use plastic drainpipe (black's best). Special speaker ports with a flare inside and out and a lip to finish the hole off are my preferred type.
