Infinity Beta 50 speakers; how do they compare?

i've lived with a pair of beta 50s for almost 4 years now, and i'm very pleased with them. i don't believe they're in production anymore, but the revel concerta f-12 is the same speaker, albeit at 3 times the infinity's street price.

Long time Infinity owner here. The Beta 50 was a European production model which makes it unique in the Infinity line up.It still retained the soft treble/warm midrange Infinity is famous for which is similar to a European voiced speaker. The Betas are a very relaxed, laid back speaker which isn't for everyone. They also have a prenounced mid bass warmth which is more akin to an American loudspeaker. The IL 40 is also similar in this regard. The newer Primus 360s is a far more balanced speaker, but still retains some of the "romantic" warmth of older siblings. Possibly due to smaller drivers or engineering, it doesn't have the at times bloated midrange which can be a listening challenge for Infinity owners.The highs seem a bit more extended than past offerings as well, which was a knock against the Betas, Interludes, and Alphas.Far from a perfect product, the Primus series really don't do anything wrong or truly excel in any given area.They do offer very good imaging and soundstaging which is a Harmon product trademark. At times they seem a touch veiled, but we are talking about a $650 loudspeaker afterall. I feel the European Kappa series was a better line up, albeit at a much higher price point.

After spending more time with the Primus 362 I am beginning to see why Stereophile gushed over these years ago...they have a very relaxed, natural timbre that is addictive...transparency is exciting and vivid...soundstaging width is equally impressive...and for a conventional speaker....they have a fair amount of depth when placed accordingly...not going to scare any Maggies owners...but this is a great budget product for main or second systems depending upon level of sophistication needed...
