I have a pair of the Model E5 Mk 2. Bought them new over 20 years ago and used them in my 2 channel stereo and still use them currently in my home theatre system. They were wonderful speakers but I wished they had a better bass response. Being the tinkerer that I am, I pulled the tweeters and midwoofer out to see what they were. Both drivers were fairly entry level Vifa units. I was surprised that a pair of speakers that cost $2000 (in Canada) had such inexpensive driver units
Since I had no faults with the cabinet and crossovers, I replaced the tweeters and mid/woofers with higher quality drivers, still Vifa brand and with the exact same efficiency and impedance. It was quickly and easily done and improved them quite a bit and I wondered why, for what would have been at the wholesale level perhaps only an extra $100, had Snell not used the better drivers. So I learned a lesson about how speakers components are sourced and speakers are built to a price point and place in a manufacturer’s product line..
Anyways, I ramble, these are highly recommended at the prices they seem to be in the used market if you are looking for a Snell, in tower form with a small footprint. They are easy to drive with 40 watts or more and are tube friendly in my experience.
