All Tannoy Dual Concentrics have a 90 x 90 degree circular dispersion pattern.
I have many Tannoys, but one of them uses the HPD-385A driver used in the first iteration of the Arden and another uses the 3828 driver used in the second iteration of the Arden.
In the case of the latter, though, I have reconed with Lockwood Audio's "hard-edge" cone kit and have also replaced the original aluminium alloy HF diaphragms with titanium ones recently developed by a Danish company.
All these older Tannoys benefit from modern aftermarket crossovers, such as sold by user "mainlytannoy" on eBay and as made by Reference Audio Components (both located in the UK).
I prefer the horns pointed right at me, but speaker positioning will always depend on the listening room and personal taste.
