Just wanted to voice my opionion on some old Radio Shack Realistic Nova 8b speakers I picked up at an estate sale a couple of weeks ago. The previous owner had these speakers from '77 until he passed on this year (original sales receipt for an STA-90 RS stereo receiver and the Nova's in the owners manual). All the drivers still work. And the surrounds on the woofers are still in tact and don't show signs of breaking down either. I have been blown away by how good these speakers sound. If you tweak the eq a little you can get some great sound from these speakers. They are very natural, smooth, and articulate. Very fine sounding equipment from RS! So, due to the fact that I was impressed by the sound quality of these speakers I went to RS's support page to see if I could find any additional information about these speakers. They had the speakers listed on their site and had the specs listed as 20 Hz - 20 Khz. They don't list the SPL or wattage of these speakers, but I had to find out if 20 to 20 could possibly an exageration or if these speakers could go to 20 Hz. I emailed my bro and he emailed be back with a list of links for test CD's, a link for Wal-mart's test tone list, and recomended that I check out the cannon shots in Tschaikowsky's 1812 Overature. I could not believe my ears - 20 Hz from a 1977 pair of Realistic speakers. I'll admit that I couldn't crank it when playing the 20 Hz test but I don't know if it is a limitation of the amp that I'm using or a limitation of the speakers. The speakers are very capable to 28 Hz which is fenonminal considering most full range speakers lose it below 45. Just wanted to say that I am really beginning to appreciate and am impressed with vintage gear. Almost 30 years old and it still works great!
