Remember, with a whizzer cone the dispersion is not limited by the size of the main cone. I know... semantics...it's more akin to a coaxial two-way. However, with a good whizzer beaming may be a non-issue altogether. I haven't heard the AN 8" but the AN 15" I have has excellent treble dispersion.

I've also experienced relatively good dispersion from the Alpair 10.3 driver which has no whizzer. I think the detailed design of the driver has a lot to say about the end result.

As said already, low or high treble dispersion is by itself not a problem, it depends on your goals, room, speaker positioning etc. In general, I read that most people find beaming undesirable because of the large difference in dispersion across the audio frequency range creates a less authentic sound field. The only experience I've had with this issue was listening to some panel speakers, those electrostatic jobs. The treble was so directional that it would sound odd if during a listening session you simply stood up and found uour ears in a zone without the treble and all the 'air' disappeared. I would not be happy with that.

Beaming is very easy to calculate. Divide 13,512 by the speaker’s actual cone diameter in inches to get the frequency at which beaming begins. From that point dispersion continues to narrow as frequency increases.
That, i beleive, is for an idealized flat piston. When talking FRs they act like a piston below some frequency and become chaotic above that, the bestter the FR the more controled that chaos is. The dispersion of a FR has a lot to do with its shape.

Hi everybody,

i was reading this post and it is a late reaction but if you have interest in a very good 8 inch fullrange look at Sonido from Hungaria...
I have the Sonido SFR-200a whit Alnico magnet in a big back loaded horn and i love it very much!
They are very affordable and worth every penny!
Before these i had the Alpair 12.2 wich was very good, the Cube Audio FA8 and now the Sonido, at 1/4 of the price of the Cube i can only take my hat of!

Regards Rudi

Before anyone goes down the road of DIY with large fullrange drivers, they owe it to themselves to take a listen to the new Magnepan LSR for $650 a pair. Of course not everyone has the room for such a large speaker but I tell ya, I haven’t heard anything nearly as good at 10x the price. The coherence is simply outstanding......a large panel that behaves like a huge pointsource.......incredible for the money.

Rudi, could you please share the info on the horn you have? I have the same drivers, now on small OBs, and I am still undecided which horn to go for. I like the looks of AION, but there are other options.

I have the SEAS 8 inch full range drivers in 2.8 cubic foot bar cabinets for the last 5 years in my listening room .
I could listen to them happily all day long .
The filter suggested by SEAS is installed in the cabinets and resistor coil values have been adjusted 3 times so far . They have 2 different circuits you can use .

Curious if you used on of their DIY designs to build the cabinet?

My only listening experience of that type of speaker was 4 huge Quads, stacked 2x2. While the sound was really impressive, there was almost no soundstage. Just two walls of the same sound left and right. I prefer the sound of my dual driver 0.53 Karlsonators, although they seriously lack bass.

The Maggie’s when placed 3ft from the walls certainly doesn’t lack ANY soundstage...... you gotta hear em once they’re in the wild!
