6 1/2" High Excursion Aluminum Cone Woofer
Compact, high performance woofer provides extended low frequency response, not typical in drivers of this size. Modeled after our similar (and highly acclaimed) 55 1860, this driver offers greatly increased excursion

    • "These are great performing drivers..." by unixd0rk on 3/15/2015
      Overall: 4.5 out of 5

      The only minor trouble that I have found is that sometimes the metal connector that joins the tab that the terminals are on to the basket can get loose and cause a "rattling" sound on high-excursion signals that sounds exactly like a coil scraping inside the gap. It took me a while to figure out that a few speakers that I had replaced were actually fine. I just had to squeeze the small connector from both sides with a small pair of pliers until the tab was unable to be twisted anymore. I had mistakenly thought that I over-excursed them while "stress testing" or dropping a needle onto a record with the volume too loud, as I do infrequently. These little speakers can take a bit of a "beating".

      I am in the beginning phases of building an experimental ported isobaric subwoofer box using two of these that I now have spare.

      I built the best sounding speakers I’ve ever heard using the 55-1862 speakers. Here’s how: I had purchased a pair of JBL TLX121 speakers at a yard sale for $2 …they had bad drivers. I replaced the woofer with the 55-1862, the tweeter with a silk dome tweeter from Boston Acoustics A60 speakers (ebay) and a crossover from Boston Acoustics A120 speakers (again, ebay). Incredible tight and balanced sound. The low end will astound you and the upper detail is profoundly real. People think I have a subwoofer. I’ll never part with these. The 55-1862 is an incredible deal at any price.

    • "Great Sound. Do not exceed power ratings" by eern214 on 12/1/2011

      A great replacement speaker for old/damaged ones! Very tight bass. Do not exceed maximum power ratings. I blew one up after hooking it to an high power receiver. Second replacement has been holding up fine as long as I keep the speaker hooked up to the smaller receiver.
