10” version of a TL806 Thiele cab

[komodo]

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.

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.

Would you mind sharing the plans? I've got a spare speaker which might work well in such a cabinet.

Here's the original 12"

Let me know if you want the 10" measurements.

Thanks. 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).

Forgot to add - the most important thing about this is that now I have two amps and can run stereo. Which is HUUUUUUGE.

Very nice Tolex work.

Thanks for the drawings, I guess I can do the math closely enough.

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.

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.
