Change to Horns or stay Dynamic

Shadorne,

You are right about the sweet spot being incredibly narrow. Within the sweet spot it is perfect but outside almost monoaural in sound.

I went from dynamics to electrostatic and now horns. I still design dynamics but for my mains its a all front horn system. And it doesnt have a narrow sweet spot, doesnt sound like mono when out of said sweet spot,doesnt require massive room and great distance for drivers to integrate, doesnt have problems with coloration etc. But its very large still can fit right in a corner so takes up little floor space. All loudspeakers have +- traits to me horns have far less - than other designs. To me horn - are size cost.

After my recent auditioning of the Acapella High Violins Mk IV I believe they are the best sounding speaker I've ever hear. I had TAD 1601c, ET703, and 4001 with the TH4001 wood horns in my last speakers. Before that many JBL and Altec horn systems, and before that Sound Labs and Martin Logans going back 15 yrs. All I can say is its a different league of listening experience. I too particularly want to be able to hear all when listening at low levels and they did that in spades. I also walked around the room listening and found them excellent from outside the sweet spot. The room was very well treated.
Just my 2 cents, listen to them if you can. Please note: I bought them and intend to become a dealer.

You might want to listen to some line arrays before you take your entire system in a different direction. They can offer some of the advantages of horns and some unique properties of their own.

I suspect what people are pointing out is that there are horns and there are horns => short throw and long throw horns and everything in between. If you make the leap then perhaps the jump to long throw horns like Cessara Beta horns might be to much room/sweetspot challenging compared to your existing setup. Perhaps you should start auditioning a shorter throw horn design to see if you can get that resolution and something with a wider sweetspot.
