komodo Posted July 11, 2020 Report Share Posted July 11, 2020 I’ve got a regular 12” Thiele cab, and then ran into a 10” EV Force 10 which is like a mini EV12L. Even though the TL806 was designed specifically for the EV12L, I thought what if I shrank it down to fit the 10”? So, I scaled the plans directly in Illustrator and re-measured everything and then built it. Surprise, it works excellently and actually sounds like a 12”. I’m most proud of the Tolex, I’ve done it before but it’s not easy. I’m using it with this tiny little Mesa TA15. 3 Quote Link to comment Share on other sites More sharing options...
curtisa Posted July 11, 2020 Report Share Posted July 11, 2020 Nice work Your tolex job looks neater than the last one I did. I re-covered a seriously brutalised Leslie 18 rotary speaker some time ago. Much swearing and sticking myself to things was involved. I've often wondered why ported speaker enclosures never really took off for guitarists. Seems a good way to boost the bass response of smaller cabs to give them an edge when competing against the big ol' 4x12. Quote Link to comment Share on other sites More sharing options...
Bizman62 Posted July 11, 2020 Report Share Posted July 11, 2020 Would you mind sharing the plans? I've got a spare speaker which might work well in such a cabinet. Quote Link to comment Share on other sites More sharing options...
komodo Posted July 11, 2020 Author Report Share Posted July 11, 2020 Here's the original 12" http://www.realoldiesradio.com/docs/EV/ElectroVoice_TL806.pdf Let me know if you want the 10" measurements. Quote Link to comment Share on other sites More sharing options...

The only swearing this time was when I guesstimated the extra space I would need on the back panel for the Tolex, and then it STILL wasn't enough. But it was already wrapped, so there was some coercion to get the panel in. Ported is tricky as it does open up the bass, but the extra excursion can be more than the speaker was designed for. This can be volume (dB) dependent. Since this cab will only be used in a lower volume home setting, I can get the bass without the risk of flub or blowing the speaker. If I used it with a band, I'd have to really be careful about over excursion. That's where that removable front plate to tune the port can come in handy. Off - allows max excursion, on - tempers that a bit, though I don't get how it's much different from an open-backed cab. There really is a noticeable difference in sound with the plate (which I didn't really think would be the case). 1 Quote Link to comment Share on other sites More sharing options...
komodo Posted July 11, 2020 Author Report Share Posted July 11, 2020 Forgot to add - the most important thing about this is that now I have two amps and can run stereo. Which is HUUUUUUGE. 1 Quote Link to comment Share on other sites More sharing options...

Bizman62 Posted July 11, 2020 Report Share Posted July 11, 2020 Thanks for the drawings, I guess I can do the math closely enough. Quote Link to comment Share on other sites More sharing options...

Here's what I started with after resizing. I can't guarantee that I didn't alter anything as I was building. There was improvisation happening for stuff like the inner frame that the back screws into. Quote Link to comment Share on other sites More sharing options...
Bizman62 Posted July 12, 2020 Report Share Posted July 12, 2020 Total accuracy isn't required, the speaker isn't of any brand either so if I end up building the box the measurements are for reference rather than aiming for a certain sound. That said, being in the ballpark of a known-good design most likely outperforms a simple box. Quote Link to comment Share on other sites More sharing options...
