Compression Horns for Far field listening

Once you hear a FR/Compression , you'll never go back to traditional speakers.
How those xover concepts lived on so so long, is a mystery to me.

Lowther has been making full range drivers of high efficiency since the late 1940s.

I understand the allure; but no full range driver ever made is really full range. The best I've seen doing the highs is the 6" PHY driver but you're doing really well to get anywhere near 40Hz with any 'full range' driver. You need subs to sort things out on the bottom. The problem is you have that bass energy that the driver is dealing with even though its not being reproduced. It can cause excursion on the cone which can result in Doppler Effect distortion at higher frequencies.

There's no free lunch.


BTW you might want to look into the Tangband 1772; in a ported cabinet they can go down to about 50hz and the efficiency is apparently higher than the driver you're working with.

Now i mentioned to Richard, classical really does not have much highs,

Nope. Classical has just as much in the highs as anything else.

The tweeter does not act so much as to add high frequency content, rather, it seems to smooth out the frequency response and make the full range driver seem less peaky and harsh.  

I've seen some where the tweeters actually fired to the rear, since the main speaker (in this case a 6" PHY did quite well past 15KHz but like any FR drive is beamy. The rear firing tweeters opened up the sweet spot a bit and corrected the room energy if you are off axis.

one has gain at say 100-120 db level, I listen at low db level, sitting 8 ft from speaker , near field blare is not going to be a issue.
when i move to arizona, hopefully i will have a bigger listening room, = can use a bit more gain.

It sounds like you might have to pad the tweeter down a bit as well. Most full range drivers are not as efficient as horn loaded compression drivers!

The seller does not speak good english, what i think he is trying to get across is that his TI horn may not be ideal match for a small room acoustics.
Anyone have experience with TI Horns can chime in please.
The TI Horn will sit on top of a 8 inch Full Range.
Is this considered a 2 way??

Yes.
The directivity of a horn can be quite useful in a smaller room. When you get reflections from the side walls, when they reach the ear they are interpreted as harshness due to the short delay time. The directivity of a horn can reduce the sidewall reflections resulting in smoother sound.


For best results use a proper crossover so the full range driver isn't making the high frequencies.
