Dumb/Valid tweeter question

[IzZy2Loud4U]

I have a set of Rockford T2 aluminum dome tweets, i want to run a second set of tweets in parallel with them however them shits are expensive. I got mine free and missed an opportunity for a set half off on ebay, still kicking myself. Anyway my dumb question is why would it be a bad idea to run a dome tweet and super tweet in parallel off the same channel? They are both 4 ohms and both would be wired together down too 2 ohms. At the end of the day all i see is two drivers with a 4 ohm coil. What am i missing?

sell the domes and stay with the supertweeters or just get horns if you want more output. 

You're making it too complicated. Stop jamming that square peg in a round hole.

To answer your question, yes, it would be a bad idea to run them both off of one channel. Pairing two of these would give you a lot of supertweeter and drown out the dome anyway.

And unless you're running active crossovers - running multiples will mess up your crossover settings as the passive ones are impedance sensitive. Or run individual xovers per tweeter
