Phil Starr Posted August 16, 2017 Share Posted August 16, 2017 I use black screws which hides them nicely, and I space them neatly as well. Ultmately they would be hidden by the frame the grille is mounted on. If I'm screwing the baffle on I always use a closed cell foam to seal the baffle Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted August 18, 2017 Author Share Posted August 18, 2017 This looks kinda open pore... it's for going around a door to keep the draft out. Think it will work? Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted August 19, 2017 Share Posted August 19, 2017 I can see what you mean. However if it is for stopping draughts then it ought to work. Unless it's from the Y100 store It will be crushed when you screw the baffle down remember so my thought is that it should be fine. It's impossible to be sure from a photo at this distance. Go ahead and if you think it's an issue later you can always replace it. Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted August 20, 2017 Author Share Posted August 20, 2017 So I finished. From wood, screws, parts, speaker and wire to a completed bass cabinet in under 30 days. That's a new land speed record at my house. All in all I am very pleased with the look of the finished cab. After some very brief testing I think it sounds good. Better than the old hartke combo it's replacing (though, I still like my little combo). I learned a lot on this project and for all the great advice on parts, software, how-to's, and encouraging I would really like to thank everyone who contributed. I never could have finished in the fashion and with the confidence that I did without everyone's help. Thanks so very much. Quote Link to comment Share on other sites More sharing options...

DIYjapan Posted October 20, 2017 Author Share Posted October 20, 2017 Update: Used my set up (TC Electronics BH250, DIY Cab) at a recent outdoor art festival. I was pleased with the sound on the stage and could easily hear myself over the guitar and piano players with out needing any floor monitors or being mic'd to the PA. The sound technician for the show was a fellow bass player and he said that the cab sounded fine. To some `Fine` may not be heavenly praise but to a first time builder I was elated. The bass player from the band that followed us came up and oogled the cab too saying that it looked really good. Several guys said that it reminded them of a traditional style of Japanese cabinet carpentry. Again, I'd really like to express thanks to everyone who helped me on this journey.

DIYjapan Posted October 29, 2017 Author Share Posted October 29, 2017 Hi-pass filter question. I was tempted to buy a 80hz High pass filter from Parts Express to stop any harmful / needless info going to the speaker. If what I've read is correct the 80hz would actually start cutting things off around the 80 hz with w/a slight roll off down to 60hz. I was originally looking for a 50 hz High pass filter but they didn't have one and I haven't got a clue on how to make/design one. Any help ?

Bill Fitzmaurice Posted October 29, 2017 Share Posted October 29, 2017 You would not high pass higher than 50Hz, and it would have to be an active filter, not passive. The Thumpinator is one example. Quote Link to comment Share on other sites More sharing options...
JohnDaBass Posted October 29, 2017 Share Posted October 29, 2017 +1 for the Thumpinator. Essential bit of kit if your amp has no built-in HPF. My Mesa Subway D800 has it built-in but my Fender Rumble 500 head does not and it's worth every penny to clean up and control the bottom end and improve the efficiency of your speaker cab.

Gottastopbuyinggear Posted November 3, 2017 Share Posted November 3, 2017 If you’re also DIY inclined in the electronics area then try the fdeck HPF pre.

tauzero Posted November 10, 2017 Share Posted November 10, 2017 (edited) I was originally looking for a 50 hz High pass filter but they didn't have one and I haven't got a clue on how to make/design one. Any help ? If you want to make one, google for Sallen-Key high-pass filters - they're second-order (12dB/octave), you'd want two cascaded to give you fourth order (24dB/octave).

Bill Fitzmaurice Posted November 19, 2017 Share Posted November 19, 2017 It won't work as well as standard construction. For instance, how do you fit the front and back? Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted March 19, 2018 Author Share Posted March 19, 2018 Got the fdeck HPF pre over the christmas holidays and have had a few chances to try it out with my DIY amp. I will have to say that it really helps keep the driver under control. It may be just me but it seems to be more forceful not necessarily louder but the notes hit more clearly and have a bit more umphff to them. So, my two thumbs up for this small handy little device. Thanks for the heads up. 1 Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted May 6, 2018 Author Share Posted May 6, 2018 WIRING Help please. I made a second cabinet to use with this first cabinet. Same design more or less. In the second cabinet I have two neutrik speakon connectors (Neutrik NL4MPR). The driver in both cabs are Eminence Beta 12a-2. I need to know how to wire it all correctly. I was thinking to wire the driver to the 1+/1- on the Neutrik NL4MPR then the 2+/2- on that same Neutrik NL4MPR to the 1+/1- on the second Neutrik NL4MPR. option 2: wire the driver to the 1+/1- on the Neutrik NL4MPR then the extra +/- of the driver to the 1+/1- on the second Neutrik NL4MPR. These are used with Speakon classic pro cable 2 core cable. Urgent! Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted May 7, 2018 Author Share Posted May 7, 2018 Wiring: update - please let me know if this is the wrong way. Thanks. so i wired the speakon 1+\- to the driver. Then the 2+\- to the second speakon. I hoped this would let me connect my original bass cab to that second speakon. NO dice. so I wired the 1+\- on speakon to the driver. Then the drivers second connectors to speakon #2’s 1+\- . Then i could connect my second cab without any problems. The drivers are 8 ohm. In this configuration does that make it a 4ohm load for my amp? Or 16? Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted May 7, 2018 Share Posted May 7, 2018 If you have wired this all correctly (it looks like you have) then the speakers are in parallel and the combined impedance is 4ohms. Well done by the way. I'm so pleased your cab worked out well enough for you to build a second. You'll be amazed at just how much that second speaker does for your sound. 1 Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted May 7, 2018 Author Share Posted May 7, 2018 Here are a few pics. #1 is my first cab (bottom) and it’s new little brother cab(top). #2 this is the rear. You can see the speakon connectors here. #3 a very crude drawing of the wiring. Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted May 8, 2018 Share Posted May 8, 2018 That looks fine, + to + all the way through. If both speakers are working and there is plenty of bass it's good. 1 Quote Link to comment Share on other sites More sharing options...
DIYjapan Posted May 11, 2018 Author Share Posted May 11, 2018 So I made a second bass cab which I recently posted about. It is more or less the same as the first cab that I made in this thread. I didn't add too many photos to this thread but I was able to make a Youtube video of the second cabs build. I will put a link to the video here. I am not sure if that runs a foul of the Basschat rules or not... if it does then to the admin please let me know and I will happily remove the content. If it is OK then I'd love to share my build with all of you. Cheers. https://youtu.be/cskZJGpgIfs Here is the link to my YouTube video. Thanks. 1 Quote Link to comment Share on other sites More sharing options...
