Hi,
I am thinking of making a dipole line array using car drivers, 4 inch 2 way drivers. I feel there are some advantages, firstly there is 1st order crossover already built in so that I dont have to design one and secondly I have seen car drivers have high Qts and decent X max both of which help in a dipole application. Here is one such driver:-

The array will be paired with 15" pro audio woofer (in dipole) to handle bass.
What do you think?
Thanks and Regards,

a line array with small full range drivers would be cheaper. this one would have the combing characteristics of a line array made of 4" full range drivers but with wider horizontal dispersion in the treble range. the combing issue is really a non-issue and disappears if you listen from a sufficient distance.
I didn't find anything like a spec sheet for the drivers so I would advise buying a couple and testing/listening first. and when evaluating cost/budget keep in mind best results require floor to ceiling arrays

The limit is the power applied ( electrically ) and the resulting distortion ( acoustic ) which is going to rise as powerful bass is sent. That's not 'built in' as a safety fuse in a trasformer, it's just how a speaker responds to different levels & frequencies . Also a tweeter has a (mechanical) crossover built in, and it doesn't mean you can send it high amplitude signals below ( in frequency ) its operating range.
The array may overcome the power issue as each takes less power but can be easiliy replaced ( mentally) by a single unit.
Greets!
FWIW, the vast majority of inexpensive speakers I've built used mobile audio drivers and more often than not were co - tri-ax ovals with some as short arrays for longer listening distances. If planning for prosound app, then be sure and use enough of the right size to get the needed polar response, power rating and ideally with +6 dB (4x) power rating reserve.
