So I was browsing a local thrift store that benefits Concerned Citizens For Animals today and saw a large pair of tower speakers that took up a good portion of their small shop space. Price was $150, so I inspected them carfully - biampable, dual 8" drivers, metal tweeter (turned out to be titanium), heavy-duty construction, and a crazy driver configuration that featured a rear - facing tweeter and midrange. I step into the back room and Google the model and find they sold for ~$1000 a pair - sold. Picking them up to take them to the car, I knew I made a good decision because they weighed about 60-65 pounds apiece. The grills alone - reinforced with wood - weigh a couple pounds apiece. Everything about them just screamed quality.
The speakers are a near mint pair of Eosone RSF-600s. The details on these are vague but it seems they were made by engineers of Polk, Infinity, and Genesis exclusively for Best Buy in the mid to late 90s. Audiophile budget speakers like Boston Acoustics is how they were marketed. They were bought out by Polk (or were a subsidiary all along - not clear) in the late 90s mainly due to lawsuit issues (they look an awful lot like Definitive Techs...) and lack of sales. The rear-facing drivers create a Radiant Sound Field (RSF), which is supposed to reduce reflections and create a wider soundfield. These were their second-best in the line-up but some prefer these over the RSF-1000s because those have built-in 10" subs that get mixed reviews.
Sound-wise they sound amazing. Everything is so clear. They may even replace my Boston Acoustics VR40s - they sound that good. The dual 8 inch woofers sound nice and tight down to about 35 Hz. The only issues were that they were a tad unclean - the store owners have cats so there were hairs all over the grills and a lot of dust.
It's amazing how deals like that can just show up.
I hooked them up to one of my dad's systems downstairs because I didn't want to carry those monsters upstairs in case they didn't work. Also the larger room gives me more room to work and is a better match for speakers that large.
