    So I just got my C-note parts in the mail yesterday. These kits are very impressive! The drivers look solid and included all air-core coils and Dayton poly caps. I was a little disappointed I got Jantzen coils instead of the new Dayton Air-cores. A few of the pieces of the enclosure were chipped as the side of the box ripped open, but for the price I can't complain at all.

    The designer series drivers look really nice for the money. The magnet on the back of the woofer is MASSIVE and this thing is Heavy! I am trying to get my 5 year old son involved in building them. We glued up most of the boxes last night in an hour. He decided he wants to paint them Gold Metallic! It was hilarious trying to explain the woofer and tweeter and crossover and port tubes to him. Kids are really funny in how they look at things. He couldn't decide if the port tubes were trumpets or telescopes.

    I am hoping to have these playing music by the end of the weekend, and will be sure to post more pics when we are done. They will be going up against my Pioneer BS21s which I really enjoy for they money I paid- but I hope the C-notes blow them away!

    Small question: besides hot glue, what do you guys like for gluing down crossover parts?

    Hey Dan,

    I received one of my 2 kits with chipped corners on the MDF as well, I basically glued and hammered/pressed them to make it even again and put those parts to face the inside of the cabinet during assembly.

    I use gorilla glue as well but I honestly prefer a good quality hot glue, in case something goes wrong or a component blows out its way easier to replace.

    Alex

    Could do the DSA175 and ND25FW in the BR-1 cabinet

    I'm in for the "buck fifty" whenever they come to the market . I'm sure they can definitely do it... Sent from my iPhone using Tapatalk

    Thanks Navy Guy, I understand and next month will work on my own project and see how it goes, I'll definitely be asking for help soon. Sent from my iPhone using Tapatalk

    The best way to test if the. 22 uF cap works (by ear) would be to disconnect the tweeter and listen to just the woofer with and without the cap on the circuit. Likely, without the cap, it will sound more "hissy."

    I decided to build a pair of these for computer speakers with my son, but now it says PE is out of stock on these for another 3 months! Is there any chance they get them back before 8/22 ?

    Is there a consensus on the 0.22 uF capacitor in parallel with the series coil on the woofer? Sounds like there is no downside, but it may also not be noticeable as well. What a tremendous value these are, heck, I'd buy them at that price with just the front baffles and not full enclosures (hint hint Parts express).

    Anyway my question was more around a different set of speakers, since I'm not a seasoned designer I was just trying to get ideas on what to do, I got myself a little CNC what can certainly be used in any kind of bookshelf speakers, so I want to play and create weir looking speakers and probably those experimental spiral shaped ones so I'm looking for already tested woofer/tweeter/crossover combinations that may work for the purpose, I totally understand that speaker design is much more than just that and the enclosure itself can change the whole performance of already proven and successful designs but I think is safer to start with those than from scratch.

    Cool! I lurk on the forums and watch other people experiment and build varying designs (a lot of Jeff Bagby and Paul Carmody designs floating around too) and then choose one that fits my need/usage and build it. You'll find people on here are very helpful when it comes to learning and experimenting, something I have not experienced at this level on any other forum! I would try looking throught the 'Speaker Project Gallery' section of the forum to see what builds are going on, what builds have been done and results of the builds.

For the price, these little speakers work very well. Haven't tested max volume but they play plenty loud for me...are you sure you are feeding them enough power?
