Just Arrived. Angstrom RPS Monitors. They look a lot like Tangents.
Using Audax drivers, not KEF, these appear to be beautifully made 'knockoffs' of the TM1 cabinets. The woofer is the same Audax as in the RS6, with the same Audax tweeter as the RS8 (but with rectangular faceplate). Essentially, a TM1 with Audax drivers.

Sweet looking speakers. I've always loved that form factor, teak wood look that British speakers had back then. I have a pair of Tangent RS-4, they look identical.
Box design pretty much is like the Tangent RS4 or TM1 however I wouldn't be surprised if the Canadian speakers were more solid in construction. Tangent used thin walled birch ply, the stock in trade of BBC type designs in the 70s that added a nice warmth that could suddenly turn thick and droney in the wrong room with incompatible partnering EQ.
Also the Angstrom's crossover is not like the Tangent RS4 which featured a huge trough in the crossover region and a smaller one in the lower mids. This was engineered deliberately by Tangent designer John Greenbank to give the RS4 an added spaciousness and to ease harshness in the sensitive crossover region. If the frequencies aren't there there's nothing to burn the ears. The Anstroms on the other hand use no trickery, just no nonsense design that provides a genuinely flatter more accurate response than the Tangent RS4.
Hi,
I know this post is a couple years old but I've been following your blog for a while and in scrolling back through some older posts today I found myself wondering: what are the stands in this photo? Did you build them yourself or..?
I have the same drivers in a rather crappy small cabinet (purchased used for the drivers), and I'd like to build a set of these using those drivers. The cabinet dimensions (per Googling) are 25-1/4 tall, 12-1/8" wide, 12" deep, made of 3/4" MDF except the front baffle which is 1" MDF. The only element I'm missing is the dimensions and depth of the square ducted port.
Anyone with a pair of these who can provide that info will help tremendously in the creation of a pair of these speakers from the ground up.
The TM1 spec's. This should suffice for your plans. Careful with the crossover though!!!!
The drive units of a Tangent TM1 live in a 25-inch by 12.25-inch by 12-inch box constructed from four panels of 0.5-inch pre-veneered medium density chipboard, with front and rear baffles constructed from 0.5-inch high density chipboard.
The 7-inch long reflex port is made from 0.25-inch plywood and 0.5-inch softwood, with internal dimensions of 2.25-inch by 2.3125-inch.
The cabinet has one "T-shaped" brace to maximize rigidity; it's made from 0.375-inch chipboard.
The front baffle is held in place by eight 1.25-inch * 10 wood screws, screwed into 0.75-inch square softwood battens.
