Hi all, I'm Thomas from the Netherlands. I'm a beginning bass player and I've never learnt an instrument before so it's going quite slow. I recently got myself a Harley Benton Kahuna ukulele bass and I'm very happy with it! My fretting hand doesn't hurt any more after playing like it did with my dad's jazz bass that I'd been borrowing, so I play it almost every day. Around the same time I got interested in building speakers. I built these three cabs and wanted to show them 
2x6" top cab
2x Fane Sovereign 6-100, 1x Mivoc XGH 258 ALU
4 ohm, 96 dB/W, 200W RMS, -3dB @ ~75Hz
Passive crossover @ 2550Hz (with switch)
25x35x35cm, 8.4kg
For the 2x6" top cab, I was mainly inspired by Arjank's Piccolo8 horn reflex cab, since I really liked the clarity of bass lines on my small horn reflex bookshelf speakers. I was also inspired by greenboy's cabs that have 6" mids and a tweeter as a vital part of the sound. I was also inspired by Bill Fitzmaurice's XF guitar cabs that mount two speakers in a cross-firing position and with a rear tilted baffle. I designed the cab using Hornresp. When I'd finished it, it was a bit peaky in the 100-300Hz region but after stuffing the driver volume it sounded a lot better.
At practice volume, the 2x6" goes low enough on its own. Over ~40W, I needs a high pass filter >150Hz to keep from farting out (xmax) and I add one or two of the TH cabs.
10" tapped horn "subs"
Mivoc AWM104
4 ohm, 97 dB/W, 200W RMS, 50-175Hz ±3dB
30x45x45cm, 16.3kg
These I did not design myself, they are THAM10 as designed by Anders Martinsson. I did however load them with different woofers after simulation in Hornresp - they are less efficient drivers so they produce less noise outside of the horn bandwidth which hopefully makes the crossover a bit easier. Also, they have 9mm xmax!
I'm not in a band so I don't use the THs for bass guitar often. I did use them as subs at a house party recently, I got compliments about the clear bass even though they don't go very low. Currently, I'm using one as a 2.1 sub to my stereo.
Practice amplifier
I'm using a tpa3116d2 amplifier board from Ebay. I modded it to PBTL and managed to cram it into a 125B size stomp box. It does around 50W/4ohm or 100W/2ohm and the gain is perfect for practising without a preamp. To my surprise, plugging the 2x6" in with a TH in parallel (so without a crossover) sounds really nice with the ukulele bass.
Big amplifier
I bought a Behringer NU1000 amplifier. It's a stereo amplifier, so I can run the 2x6" on one channel and the THs on the other channel. It should do about 2x210W RMS into 4 ohms or 2x380W RMS into 2 ohms. And it weighs only slightly over 3kg!
Although I still have some finishing to do, for a first build (apart from some small bookshelves) I'm really happy with what I've made
