DIY a baffle for JBL fullrange and super treble Celestion
I have a pair of JBL 2120 Pro and super treble Celestion ballet, I want to make a new baffle for them. I have find on internet already but didnot have any details for JBL driver like this :confused:.
Please could you help have a suggestion or document/picture drawing?
JBL 2120 Pro loudspeaker
Extended range transducer, 50hz to 8,000hz, Imp. 8 ohms, 60 watts contineous, 98db at 1w/1m, Fs=65hz, 3-inch edge wound aluminmum voice coil, BL=1.4x(10)7. Pictures too.
However this information provided by JBL is insufficient to design an enclosure (computer program or charts) with out other T/S parameters: Qes, Qms, Qts, Vas, Re, Le, Sd, Xmax.
Note that Qts can be calculated easily from Qes and Qms. Xmax should be known for a complete design. Sd can be estimated from the drivers frame size (results will vary with your estimate)
If you can not find the required T/S parameters, you can measure them easily with a WT 3 instrument available from Parts Express, see their on line catalog, page 168 $99.88usd.
Thanks Michael for quickly feedback,
I understand your advice, but I dont have much knowledge about this. I'm looking for a Bass reflex enclosure plan that can using for my JBL fullrange driver and supper treble HF-50 (optional). The baffle plan is as simple as good for me.
Any idea for this?
Thanks for any feedback
Please updated with more information details of JBL and Celestion treble
