    Hi All,

    This weekend I was driving by a new local thrift store. I had stopped in a few weeks back but did not seem to find anything good. This weekend me and my gal were driving by and i decided to stop again. Had a lot of overpriced vinyl, and random crap bookshelf speaker.. the usual at most thrift stores any more now days.

    As I was about to leave I noticed a set of the Optimus LX5's. While I tend to stay away for low budget gear, I do love some of the realistic lines (Minimis/Nova). I actually walked out of the store, and up the block to my truck. I than turned to my gal and said, I cant leave them! So 20bucks letter.. I was the proud owner.

    They are dusty as all get out, but im planning a full cleaning, new foam on the set. I am ordering the foam today.

    I've seen some good/bad reviews on the set, but i do know they are iconic Optimus speakers.

    I think im addicted to buying audio gear... I've been doing good for the past few months but I just felt like leaving them they would not have been properly taken care of...

    So for what its worth... i have a set of LX-5's that ill restore and probably never really put to use..

    Not sure what info im asking for other than any one on the site know any good mods for the set? I know to use Poly fill. :)

    Kind Regards,
    John

    I have a pair also, I may get to refoaming them eventually, they were free, saved from the recycler. I thought they'd be fun to play around with

    Im in the same boat... they seem to be fun to mess with. They are nothing id put in my living room, but could very well replace my work speakers. They would look nice in my cube.

    Kind Regards,
    John

    I use one. Replaced the woofer with a Peerless woofer. I use it for center channel.

    Welcome to the club! :biggrin:

    Are these the ones with the port on the front?

    I owned a pair that I ended up parting out. I still have the ribbon tweeters for some project in the future, along with the crossovers. Tossed the cabinets and woofers. They were nice little speakers for what I paired for them, but not nice enough for me to invest time, money and effort in reforming them.

    Hope you enjoy yours.

    Here is a link to a tear down video.

    I also have a pair that I haven't done anything with.

    Thanks soundboy,

    Yes, they have the dual ports up front. I did notice that the previous owner had stuffed them with straws. I read on the site that some folks did that to slow down the out flow. Not sure if that is true or not, but mine had about 10 straws stuffed down each port.

    I alos read that they were not well built... Not sure why one would think that, they are metal enclosures, textured, and solid. They seem to be built like mini tanks.

    They will be going into my collection, they just look to damn cool to be rid of. I did read that they make great surrounds. I may end up connecting my A-71 so i can run them as rears. I will be documenting the foam work on this thread.

    Glad to be a part of the LX5 club, all day any day!

    Kind Regards,
    John

    Thanks Boonaroo,

    I usually would not take the time to restore older Radio Shack gear, but the LX5's just look to damn cool. dont get me wrong, I have a set of JBL D280's on my cabinet right now waiting for repair, for me, the LX5's are collectable enough to restore. I actually enjoy the foam process.

    The trick will be to mount the foam on the rear side of the cone, JBL was known for this, and I've foamed/coned enough now that this should be easy work, so i should not spend to much time. the cabinets look good enough to be used again and look nice.

    I will be restoring them solely for my cube speakers, will need to find a nice desktop amp. They will look good at work, and im sure will get a lot of questions from co-workers.

    Kind Regards,
    John

    I was going to recommend trying that....the straws in the port.

    I think the later version of the LX5 was not ported. So maybe there's something to the straws?

    I don't own any LX5, although I am a fan of the LX series.
