Lightbulb Which Are Best Budget Compression (mid-h.f. range) Drivers?

Hi all!
I know that I wasn't so active here on forum,but forgive me,at least I've read a lot....
I want to build an horn based system(tractrix round horn,midbass front horn and tapped horn as a sub) so please tell me wich would be the best budget(4,500Hz-18KHz)compresion driver do you know??
My budget is around 300$,including shipping....I wonder if I can afford an entry level but good quality pair of compression drivers,something to beat(I know that a good pair will blow away paper drivers,but I have an small budget!) an extremely good vintage full range Telefunken paper driver(I have an offer from someone)wich I was intended to use in a tractrix horn...
Plus,knowing the fact I'm at the beggining with my DIY horns,I would like also to buy a good pair wich can go high enough so I be able in my first period to not be forced to use tweeters,this way reducing the coplexity and cost level of my first horn project....
Thanks for your pacience,your collaboration it's highly anticipated!!

Happy Hollidays and God bless you!

Hi,

Looking at your numbers, it tells me you are looking for a tweeter. Did you mean 450 Hz to 18K by chance?

On a budget? Maybe the Selenium D220ti. Tho some prefer the B&C DE10-8 Both are about the same price in the USA.

Don't know what prices you can get in Romania or Ukraine.

DE10 or the BMS 4540 if you have the budget and screw on is OK.

Thank you so much all,for your kindness and pacience!
Cal Weldon,sorry,I was writing 4 or 5oo Hz(it's not "dot" after 4)so it's not only a tweeter,though going from 500 HZ to 18 K or something I've just read that maybe it's not possible to have a clean,linear response on a budget one,what do you think??I insist again on my target: I want something to have better sonics value(dynamics,soundstage,timbral acuracy,transparency,texture) than a wonderfull vintage paper driver,so I was thinking that a nice,entry level,decent compression driver(I have time for upgrades later to those TAD,JBL,VITAVOX or....with $$$$$)will do the job....
Panomaniac I will look for those drivers......
Brett thanks a lot but I'm not totaly familiarized with compression drivers's construction(I look at them for about few days)so i have to make my homeworks more serious.... the "screw on",it's the metalic part with the cilidric throat atached with screws on the front of the driver ?!?
It's a honour for me to talk with you guys,I respect you a lot....
Happy holldays and God bless you all(from an orthodox soul from Romania )

I have both units, D220Ti can cross lower at around 1.6-1.7 Khz and DE10 above 2Khz, the has smoother perceived top end. Once D220Ti is burnt-in it is not that bad. I am using it now. Both needs compensation at freq. >8Khz.

Does anybody have experience with P.Audio drivers? WN-D34 or BMD440 look good on paper.

Panomaniac thanks,but it was a confussion(forgive me)I was telling to Cal Weldon that i put 4,5oo in sens of 400 or 500 HZ so please if you think that is something to behave pretty good in this range.....?!?or maybe I would change my initial scheme and I will use some good budget mid compression drivers and add one of the tweeters that you've just sugested me....but again,i have to see if I'll have all the money necesary(because I've already bought an wonderfull tube amp-a 45 SET-2x4 W,and surprise.........my wife stiil loves me!!)
ttan98 please tell me what do you use under 1.6-1.7 Kz??

I really doubt any budget CD will go down to 500Hz without sounding harsh even at the low playback levels in a home environment.

For example, the selenium 220ti panomaniac mentioned has a recommended cross-over point of 2Khz at 12db/octave. Off-course this is a conservative rating, for PA use.

Then again, if using a CD from 1Khz and beyond, the idea is to select a very good one in order to have some decent performance in the very important 1Khz - 20Khz region.

Best luck with your project!

Ditto above. No budget driver (or horn) is going to do that. But you can get close with some vintage gear such as the Altec 811 or 511 horns with the 1" drivers. I have both.
But even my big, heavy (14 Kilos) Altec 291 drivers won't really play down do 400Hz with authority. 500Hz, yes.

So to keep in a reasonable budget, you should rethink your system. What you want to do is possible, but not easy and not cheap.
