Tweeter box

The dispersion is nice and wide at 100w x 50v and these units sound quite good. They extend out to 20 KHz as well and are very cheap." A quote from Rog on the FAQ section.

Quote from same faq, same section.

This would be in my opinion the best option for you. <-CUT->. Best option is the 3 way with 8� on mid and a slot tweeter doing HF (see if you can find a Selenium ST 320), using the Eminence px or pxb3 5k crossover. Not the cheapest option this, but the best sounding.

Do you see the pattern? Rog recommends what would sound best first. And absolute last is the el cheapo option you recommend first.

There's a big difference between bullets ok for a monitor cab, and bullets to use on top off a stack with 4-6 18"'s under them as sub plus the rest of the stack.

Toxic wrote: Yes the Fane bullets are better but are like more than 3 times the price. £50 inc vat each Fane bullet, APT80 I know where to get them for £14.55 inc vat. Depends on there budget though. BTW: I heard Fane bullets too and they are not that much better sounding than the APT80.

They are more expensive for a reason. Because they sound better, last longer, and you need less of them. And You'll find many people recommend FANE bullets/Slots just behind JBL's.

Toxic, you have an acute case of "80's sound man 'itis".  Buy lots of  cheap stuff and stack it high, when it blows, buy more cheap stuff.

Toxic wrote: The Fane slot tweeters however are completely amazing sounding. So if them people can afford them.Go for the Fane slots.

So Finally, after I jack you up, and you then read Rog's faq, you finally  say what you should have said in the first place. Reason for this, you often make ill advised suggestions before getting your facts straight.

Experience,  "PA Company owners", Quality sound owners and this website has shown me the way to build a PA rig is always buy the best you can afford, new or used. Not the cheapest you can find. This is why you often buy cheap cack, get dissappointed with it and often sell it at a loss.

 

I have some APT80s and they dont sound as nice as the APT150s.  I wouldent go for a horisontal array with them, you will proberbly get loads of comb filtering, a vertical line of APT150s would proberbly be better, they have 100 degree horisontal despertion anyway so theres no need to array them horisontally.  I think you would be better off with some fane bullets anyway... 

what is this comb filtering, and why would it only happen horizantaly instead of vertically?...  I cant build my whole soundsystem verticaly if im going to make some form of array. I suppose i could handle the horns being stacked vertically, but the 6.25" drivers i am going to have to angle slightly to the left and  right of the apt 150 to get decent dispersion with upper mids.  Delay though,  i have no idea how to measure such a thing.  Isnt it true that horns delay but bullets dont?  If i jsut went with a bunch of the apt80s and a bunch of beyma 6m180s, i would imagine i could have nice midtops.  i have absolutely no test equipment and a tiny budget so i cant really follow lots of the advice i get on this forum very well.

If i did use a vertical array, however, would it be possible to use a horn like enclosure similar to the m102 to get better dispersion? i dont know a thing about calculating horns.
