Bottom Line:   
I'm not absolutely positive about the year my pair of Kappa 5.1's were originally purchased. I was told late '90's. I got them free from a family member in 2013. The foam surrounds had deteriorated and he was not interested in repairing them. Replacement parts and repair kits are still widely available. With very little effort and a very small investment, they were fully functional again and sounding great. They have fantastic bass response and excellent high frequency extension. That tweeter is fantastic. They are missing a little in the mids, but if you use the Kappas as front mains and add center channel as part of a theater setup, you won't notice. I use mine primarily for home theater, but also for stereo music. Wide frequency response makes them great for modern music/ rock. They spent some time with both old Kenwood and Primare amplifiers. Great speaker to find used, but do expect to repair the foam surrounds on the woofer and mid-range driver after about a decade of use.

Bottom Line:   
For shear musicality you can't beat the Kappas. Not for the price, that is. I paid $450 in 1995 which was a 25% off sale price. I state the price I paid to make the point that I was on a very limited budget and didn't expect to be able to get superior quality sound for less than $750. I found the Kappa 5.1s at the lately departed Circuit City. I couldn't believe my ears that they were as inexpensive as they were. They easily outdid all equally priced competitors and more expensive models, too. My only complaint is the midrange could be a little stronger. I have since heard the Kappa 6.1s which have a much better mid range driver that is extremely crip and full. CC didn't have the 6.1s at the time so the 5.1s came home and have been pumping out amazing sound for 15 years.

The bass is very good for an 8 in. driver, tight and rarely punchy. Coupled and low pass filtered with a sub woofer the 5.1s can blast beautifully at 100+ watts. The character is warm and full thanks the the cabinet wood and size. Modern plastic or composite speakers can't compare to sound from good wide wood. I will probably keep them for another 15 years.

Bottom Line:   
For shear musicality, the Kappas are hard to beat. The emitter twitter is a marvel. The overall sound is very well balanced and smooth. I feel the midrange could be stronger, the Kappa 6.1 midrange is much fuller and crisp, but I cheaped out and stuck with the 5.1s. The bass is very well defined and tight, especially for an 8 inch driver. The cabinet wood and size are a major plus.

As front speakers they are transparent, in fact as a center channel its excellent. If coupled with a good powered sub, they don't miss a beat and can blast 150+ watts easy. Modern Speaker boxes are usually plastic or mixed materials that just don't have the warmth and depth of good wide wood. Use 'em every day. 15 years old and going strong.

Bottom Line:   
Others also metioned these speakers sounded better than their larger siblings and I agree, that is one thing which prompted me to purchase these. The larger Kappas were much more costly and didn't seem to produce the clarity in the highs and midrange of the 5.1. I would give them 5 stars in their price range, but will give them 4 overall. Obviously you can find better speakers if your willing to spend a lot more money, but these are incredible in their price range.

My system:
Onkyo TX-SV919THX
Onkyo ED-901 AC-3 processor
Infinity Kappa 5.1 fronts
Energy RVS-1 center speaker
Infinity in-walls (surrounds) don't remember model#
Onkyo Integra M-504 amplifier

Bottom Line:   
A very fine performer: sweet detailed highs, clear midrange and good bass. I originally powered these speakers with a HK AVR20 (65 watts per side) and found the amp a little underpowered. However, after upgrading to a HK AVR85 (90 watts a side) these speakers really came alive and sound super, especially at high volumes (they sounded constrained before). Moreover, they are pretty to look at and nicely made. The hardwood veneers add to the classy sound.
