Ever heard of, any opinions on, these speakers?

Not famiiar with those specifically.

Tall towers with wide spaced drivers tend to work best in larger rooms with some distance to listening position for the drivers to integrate coherently.

Here's my off the cuff shot at an analysis of the speaker (BTW, anyone here been watching Top Shot? It's a show on Netflix in which 16 marksmen/markswomen compete to see who's best at a wide variety of skills with an assortment of weapons. Very entertaining).

The price point, if accurate for that pair of speakers causes me to pause. That's supposedly a LOT of technology crammed into a speaker for that price point. Somewhow I think the quality must suffer as I don't believe it would be possible to get a great cabinet, crossover and driver set for that amount.

Now, it's made in Canada, which bodes well for it. Paradigm and PSB are also Canadian, and they are fine speakers. The Canadians have the advantage of the use of their national acoustic research center - forgot the name of it. If Sinclair has been developing their products in similar fashion it could be a sleeper, a good value.

I just bought a pair of speakers which is the only one of its kind in North America - the King's Audio King Tower. The price had to be right because of the uniqueness and thin chance of repair, and it was. You may want to call the company and speak with a rep regarding the speaker line. That may give you a feel for the people and products. It's hard to tell the true health of a company from a website, but the company looks to be large enough to sustain the product development.

Finally, another speaker which would likely compare well would be the Golden Ear Triton Towers. I have heard them and while not the last word (What is at that price point?) they are quite good. Having a similar ribbon for the top end you'd probably like them, too. The Golden Ear would plumb deeper in the bass as well, which would allow you to avoid having to get a subwoofer to get HT action or have the proper foundation for heavy rock or electronic music.

I've seen these in a few stores here in Ontario. It was my understanding that they weren't a very high end speaker>>>just a pretty box! (I deal with a couple of extremely honest retailers who both told me that these were "mistakes" in purchasing!). I believe these were made to compete price-wise with the likes of Monitor Audio's silver series or Paradigm's products (in the $700-800 price range)
Hey, everyone's ears are different so the best judge will still be your own ears as far as I'm concerned! (I admit that I didn't bother because these aren't what I have been looking for)

I'm a Sinclair Dealer. Very well made, and nice looking speakers, nicer than they look in photos. I was really impressed when I opened mine. Fairly heavy, at about 75 lbs. They won't beat out a 5k pair of speakers, but, I'm enjoying mine alot at the moment. Pretty hard to beat for the price.

I'm running mine at the moment with a 300 watt Sunfire amp, Adcom GFP 750, and an Arcam DV139. They will play loud, if you want them to. Mine show no signs of distress, even when pushed far beyond where I would ever listen.

Albert, MSRP on the 460T is $1500.

They seem to be marketed as the Roth Oli 50 in the UK.

The Roth Oli 50 is not well reviewed.
