Default Has anybody tried the Jaycar 2" full range?

I got sent a new Electus (ie. Jaycar wholesale) catalogue today which has a 2" widerange driver for AU$1.10 each.

Has anybody tried this part (Jaycar/Electus part no. AS-3020)?

At this price I'm tempted to chuck 10 onto the next order I have into Electus.

I have almost zero speaker design knowledge, but would these be worth using in a line array? How many per side?

Claimed specs are:
- Paper cone with cloth surround
- Nominal Impedance: 4ohms
- Power Handling: 2W Max
- Sensitivity: 103dB 1watt 1m
- Voice Coil Resistance (Re): 3.5ohms
- Resonant Frequency (Fs): 276Hz
- Mechanical Q Factor (Qm): 3.5134
- Electrical Q Factor (Qe): 1.2369
- Total Q Factor (Qt): 0.9148
- Magnet Weight: 1.35 Oz
- Vas: 9.45Lt
- Dimensions: 53 x 53 x 30mm

I kind of wonder whether it can be full range or not.

Phase array speaker system. That what I call it.

Check from (PDF): Sd, Mmd, and think about the sensitivity....

No real low end, really high sensitivity, high Q. I think an open baffle line array could work out with a woofer crossed in. May not be able to use a sub, as it would have to cross to high. Just be sure you don't give them too much juice.

Please, check the parameters @ http://www.jaycarelectronics.co.uk/p...ed/AS-3020.pdf

Sd 0,0108sqm (dia=117mm) Mmd -0,06g (negative mass). . .

This was a 2" driver, with Sd closer to 0,00108sqm ?...

LMS asks for Sd, Re, and added mass for parameter derivation..... - typo ?

These parameters are not correct.

Fortunately, those are params we can measure ourselves, then post for others
