  • "Good for the price" by Winman99 on 12/10/2011

    I found some Axiom AX 1..5 speakers cheap, that other than having dried out foam surrounds, are in excellent shape. I purchased these to use until I can get a proper repair kit for them. I must say that I am pleasantly surprised how well these sound. Lots of bass for a speaker this small, and they have decent midrange as well. I would say the original woofers are slightly louder (higher SPL), but these are close, I backed off the treble on the amp a tiny bit, and all is well. I like the vented magnet to help keep the voice coil cool. If you are looking for something inexpensive to get an old pair of bookshelf speakers going, these will work great. The high rating is based on price/performance. MCM was quick with the shipping as well.

    to start, let me tell you these have some of the stiffest cones i have ever seen on speakers this size also, they have a huge xmax i have never seen at their size they are pretty loud, but on the highway with the windows down they were a bit quiet for my liking...but they sounded so good i had to find a way to use them...they are the best headphones i have ever had:D

  • "Great Replacement Speaker" by TheLazyComic on 2/11/2011

    My old 6.5 inch woofers in my Optimus speakers fell apart. Now I love these speakers. Everybody that had heard these speakers loved them. Well, after 13 years of use, the foam edge on the edge of the woofers, (only one of them oddly enough), fell apart. I didn't know how to go with this. I insisted on keeping the cabinets, but what woofer replacement should I get ?? Well, let me tell you, these replacements were the perfect fit. Very close to the original specs, but a bit better. They did the job, my speakers sound as good as they ever did. I have a small studio and these have always been my studio reference speakers... and for good reasons. I'm glad to have them back sounding as good as new. I would highly recommend these to anybody.

    Used these as mid-woofers in the front doors of an 01 Dodge Intrepid, miles above the nasty, nasally coaxial Volfenhag speakers I'd popped in there previously. In the immensely restricted airspace of the door, these easily reach down to 50hz, and the generous xmax helps them cope very well with bass. Of course, no replacement for a subwoofer, but these will give you all but the lowest bass. The midrange is always the concern with poly woofers, but it's excellent with these. I will admit they're a little 500-1000hz heavy, but a simple loudness eq will tame that. Overall, very pleasant, punchy woofers with good low end bite. Buy 'em, build some stuff! I plan on doing home theater 3-way MTM towers with these as the midbasses, the cheap soft dome MCM tweeters, and the 12" mcm woofers in the bottom, I'll be posting reviews of all of those then.
