I don't know of many great 1.5" horns, but there are loads of good  2", so I've stuck to 2" comps.

Paudio PH4525, sounds great with many makes of 2" comp, with corrective eq for 12khz+.

Sounds better than JBL 2380A  that costs a fortune, and breaks so easily.

As said previously, I have 12x of the EV HP940, which maybe similar to the Porn Horn 2" horn, and I've heard  them do 16khz+, with JBL 2450.

One of the Staysis tops, also  uses Beyma CP755Nd 1.5".

Heard them in a Reggae Dance, could not quite believe my ears.

I'm sure Void engineer was there that night, and set the Void LMS, they were using.

think it was the porn horns used that beyma comp... not technically a void product, more like a rog / pro audio parts product.

i think that porn horn high horns are in the void stasys phil now, but i don't know what comp is on them.

I would also look at the RCF ND950. 4" VC with still a good response higher up.

Can't remember exactly, I'm not a Void groupie,  Staysis something.

But combinations I've used personally for years.

B&C DE85 + B&C ME60
Beyma cp750ti 2" + B&C ME60 or ME75 Alu horns,
Beyma cp750ti 2" and Paudio PH4525

In a nutshell, get rid of BMD750 

Beyma 750ti probably best of the budget 2".

Hi! 
totally okay with making it easy using decent comps.

What models of Void tops do you mean exactly? Which ones use that Beyma compression driver? 

Thank you very much

Ant.

Hi, 

Thanks for the replies all. Lots of info to digest in the Audio Heritage thread in the thread shared by fatfreddiescat. I think that will take a few sittings to digest.

MarjanM & Levyte357 - Thanks for the replies. I'll have a play about with the High Shelf EQ.  Thumbs Up

MarjanM - Sorry, I'm gonna be that guy and ask The Question. Why would you not put a 1.5 comp driver on a 2" horn (using an adaptor)?

Also the 2" horn is very important.

Been easily getting upto 16khz,  with Beyma CP750TI, with B&C ME60 & ME75 Alum horns.

But they are decent, not Cheap sh*t.

I also have approx 12x EV HP940 horns, which are best I have ever heard, but will not be going anywhere.LOL

First of all you can not put 1.5 inch exit driver to a 2 inch throat horn.
I mean you can, obviously, but it will have issues.
Second, just add a highshelv eq above 10Khz and it will be way better.
