    Great build! I love CerwinVega! I wish they would do some nice wide baffle home speakers with the high build quality that the stroker sub has. They are definitely capable of it. One free tip that you could have done, and might consider on all your builds is to round over the inside of the woofer hole on the baffle. This can help with letting the speaker play to its full potential and doesn’t cost anything. 👍🏻

    • @DIYhyfy
      @DIYhyfy  5 месяцев назад +1

      Yes I hope they release some nice tower speakers in the coming years. They do have a pretty extensive line-up at the moment. They're just not very visible as a brand.
      If you notice on the recess, the t-nuts actually hang out just a bit. I was afraid rounding over would expose too much of it, and be weaker. This is a HEAVY driver, so I played it safe. But yes, definitely a good idea in general.
      Thanks for watching!!

    HEY!!! A fellow user of the "thumb on the button" rattle can painting method.
    Nice work on the cab.
    Although...
    I did flinch up a bit when you stepped back to hit the lacquer with one last little kiss from your sprayer
    IN THE OPPOSITE DIRECTION of everything else that you had laid down. Lol.
    I have done this many times laying different types of finishes and have only had it effect the sheen once or twice.
    But when it does... I just feel sick about it, so it's become a reflex for me to flinch whenever I see two wet products overlapping perpendicular from each other.
    Like a jump scare video. lol.
    But I can be anal about things "just in case" but that one can for sure bite you on big flat surfaces like that.
    You're doing a very fine job and you have reinspired me to consider doing something this weekend.
    I have an older Peavy Backstage guitar amplifier that has working electronics, but the box is rough, and I have thought about
    Building a new one from red oak with an ebony die and lime wax finish (Cerused finish) and make a solid copper face plate
    along with 8 corner covers from the copper as well.
    The speaker it those are nothing to look at, so I need to come up with some type of fabric to cover it with.
    Something blk and copper colored
    I will also change the knobs to something better (to match new design) than what is on it now.
    I anyone thinks what would be a cool knob idea (vol / tone / drive, etc) let me know, I am thinking about something that size
    that already exists that I could drill an apx. 1/2 in. deep, & apx. 3/16th dia. hole in the rear of it to mount it to the Attenuator
    Black/ copper color related.
    The only thing that I have thought of...
    I was thinking about soldering a few 1 oz. Morgan copper dollars or something of a similar type design
    (many different styles from $2 to $9 ea. .999 pure) to a hex shank rivet nut just because the nut would be an easy way to make it mount, but something cooler, would be way cooler.

      Jump scare lol I get that. It did turn out fine, but I was going crazy with the lighting in my shop. With that sunlight coming in from one side, it made it look like my spray pattern was all over the place. I couldn't resist hitting it one more time lol even then it didn't looked right in the sun. When everything cured it looked great. Not the first time I've had sunlight play tricks on me!

    I think you should have done bolts instead of a cup cut out for the wire conneciton outside the box. years ago I would have not known the improvements that avoiding those would lead to. Tubes (mainly for home) or nice lugs to bolt to is what I see more of the pros use.

Found it on the side of the road on garbage day. It still works, but maybe after a recone I'll be impressed, dunno.

    Nice build! I love cerwin vega, and the strokers are high up on my list of things to build. Normally where I live I see the stroker built with tubes, like standard round vents. How do you get the measurements for the square vent you built? I see that you use winisd and square vent, it your is like a small horn with those angles etc.

    • @DIYhyfy
      @DIYhyfy  5 месяцев назад +1

      Hi, square & round ports act as the same thing. There is a mass of air inside that can act to extend bass for some frequencies. If you're familiar with winisd, you can simply click on the square or round port icon to change between them. In general I use slot ports, because they are cheaper and usually easier to fit inside an enclosure.

      @@DIYhyfy Thanks for your reply! I’m not familiar per se, but since last night I’ve modeled boxes and boxes. I figured out that square vent thing now. But, the vent you made in your stroker box, did you take in consider the displacement of the actual port?

  • @Grommet2007
    @Grommet2007 5 месяцев назад

    Nice build! What are the internal dimensions of the box and the vent? I've got a BOXPLAN workbook that can predict where the out-of-band vent resonances will show up, and this are impacted by the internal dimensions of the box and the location of the vent and the driver in the box. The impedance curve shows a bit of loss around Fb BTW, but I suspect that's more due to the driver than the box, because the box looks pretty solid.

    • @DIYhyfy
      @DIYhyfy  5 месяцев назад

      Hey, I'll have to check for enclosure dimensions when I get around my PC. If I recall, I believe first port resonance was pretty high, if that is what you're referring to. I believe it was at least 140 or so, but I'd have to look again.

      i know sometimes there customer support can be funny but they were very helpful with me when I called just to ask questions about the new strokers i have the OG 18' and OG 12" D4 voice coil models. the biggest issue when rebuilding them is getting the 8" top spider not the lil 6" one most rebuild kits are offering. Theres only a handful of the 8" spiders left to restore the 18" models back in a like OG state and one of the guys that rebuilt my one has 3 of them the others are on ebay from a guy who rebuilds all JL stuff in the groups. I let rebuild and restore rebuild my one and it took him almost 6 months then when i put it in the enclosure i built for it to test it i realized the surrounds were covering the screw holes on the basket and that the speaker gasket also covered the holes and werent properly lined up for what I paid $500 and the long wait because he flew a guy in to help him rebuild it and that did work that sloppy during the final stages of the recone i will do it myself or actually take it to Andras Radvanyi to do. I suggest buying some OG strokers if you can its cheaper to rebuild them yourself. Thats what i will do if i blow these. But to be honest it doesnt seem as if the newer versions have and real advancements like the claim other than vents at the bottom of the motor and possibly a slightly bigger 4" voice coil but by only making them Single Voice Coil was why i didnt see a reason to purchase them. Did u get them reconed yet?..

    1:40 why would you have a 15'' subwoofer that doesn't have even response curve, and more importantly no bass.... one of the most annoying things i notice with speakers is the absolute terrible low frequency response when listening to electronic or rap music the frequency for bass that's hard to reproduce EVENLY is around 20hz to 60hz and then you want the hard to reproduce punchy bass not from the subwoofer but from a woofer that's around 100 to 200 hz and then a Tweeter for 1k up

      I love listening to my furniture. My couch has a wide soundstage. But my recliner can be a bit harsh on the top end.

    I'd set it on its side not up

    Too bad its just the cheaper Chinese made 8/10 tenths as good as the only original STROKER. 15"/18"

    That's not the "legendary" stroker. That's the new stroker. Its a chinese made copy that the company that owns the cerwin vega name today put out. The og legendary stroker has an adjustable slide in the center, that one isn't adjustable.
