In no certain order:

I am planning on using a sub. In fact I am working on 2 18's that will be powered by a 500 watt Hafler amp. I think I have that covered.

EQ: I am planning on getting a DEQ2496. I have had one on my wish list for quite some time and would like to get one for use the RS8 array eventually. It seems that most agree the 2496 is adequate for this job too.

Lack of bass/highs. Bass is covered. When you buiild an aray for $300 in drivers you will sacrifice something, particularly in off axis response.

Different divers: I picked these Aura's based partly on price but also because they will do the job. I am sure there are better options but they will more likely improve the low end (which I do not really need) more so than the high end. The low end will (assuming) come at the cost of a larger enclosure and a fair amount more cash.

Adding a tweeter: I have considered it as a future option. If I do so I will simply mount it to the side of the existing array as close a possible to the line. I do have a pair of Fountek 3.0's that I got a good deal on that would work great. Definitely worth considering but that is another project for another day...

I want to build a set of nice speakers that will sound great for the small amount of $$ spent.

Now, does anyone want to go in half on 100 Aura drivers?

Thanks,
Aaron
