this is all a possible setup for my brothers 89 lincoln he wants an SQL system. I was thinking about getting him some boston pro 6's. I want to get him some horns that will sound nice and entend into the low-mid frequencies but not get too high so its annoying. I know horns are very effecient and little power can have them screaming. I don't want them to scream at 20,000 hz though, and i need something to cover the frequencies above the horns. If you think the horns will sound nice and smooth covering 500 - 20k then im with you on that, I just don't want to spend his hard earned money and he not like his setup.
This is one forum boner that probably doesn't need to spread, horns are a bit more advanced than most on this forum are ready for. With horns you're also going to need EQ's, optimally 1 per horn. You'll probably going to have to full active since the mids will need bandpassing. Beyond that, without an RTA, the EQ job you do might not be the greatest. You'll need a kickass pair of mids to keep up, either a long throw 6.5 like the XXX or a nice set of 8's. Honestly 99.9% of the world are more than fine with the output a good set of components provide. You can always do kicks if he is concerned with imaginng. I'd just go with a nice set of comps and save quite a bit of money. Horns will cover most of the way up to 20,000, they fall a bit quicker than tweets, but it's not as much of an issue anymore. Plus tweets arent' usually sensative enough to keep up with a set of horns, nor do most people notice lack of the super high end frequencies, for most the prescence just gives them a headache at higher volumes.
Pretty much everything Tempest said.
No need to use tweets with horns. So just wash that idea out of your head now. They are designed to play from the crossover point on up; don't cut them off any sooner than that and their output would just drown out the tweets anyways.
Mids will have to be beefy. Anything less than a long throw 6.5" is not ideal as you'll just end up choking the horns down a ton to get the level matching between the horn and mid correct. And a good 8" would be better.
Remember than a good EQ will be absolutely necessary. And most horns require that you go active.

Agreed 100% with Squeak and Tempest...

2 good mids would work better than 1 set simply because of the massively increased surface area. This might not always be the case, depends on the sets. You'll gain around 3db for doubling your SA and then a bit more because you most likely increased overfall excursion You'll might have to do a lot to your doors to make it all fit though. You'll also need 2x the power than the 1 set would require. If your going to end up cutting your doors, I'd just try to fit a set of 8's.
