thanks, good to know your still happy with the
12ndl76. if the LEX13ND8 does 4x the output out of the same tham12 then that sounds like a good cost heh

Thay Beyma looks very good, if you have the power it need it will surely be a good match. But it costs double as much as the b&c ndl76, and if you account for both power and loudspeaker, the whole thing will cost you probably 4x as much. I'm very happy with the 12ndl76 performance!!

I was thinking of using B&C 12ndl76 also for my first tham12. Would you use it again or would one of the things that you do differently if making another tham12 be to use a different driver?

Out of interest, what batteries are you using to power all this?

Thanks! We were outside raving a bit yesterday and yes, the babies are amazing :) You feel the bass clearly!! I needed to keep things small so I chose the more compact tham design, otherwise I was also considering building a cubo. Am not disappointed :)

Looks really good!
Ever since I build my Cubo 15 I have been very interested in tapped horn designs. Bet the Tham 12 sounds good. Would you say that there is a lot of bass from a small system like this? Do you feel the bass clearly?

Hi! Just wanted to update this a bit, I ended up getting a pair of Turbosound ip82 as tops, as theyre super cheap and perfect for my needs... Also got s 2x400W from Sure electronics to run them. The combination is great!! A picture: |

Damn, those measurements don't speak all that well about these little boards... but I'm still pretty happy with mine! Gonna be ordering 2x300 or 2x400 soon. I wonder whether the 500w boost stage can really output 500w...? In that case, I'd go for the 2x400, otherwise 2x300 should play the trick as well... Thanks for the line array idea! I definitely like the idea because of its simplicity and size. How would be the kickbass be when playing outside? I'd need to hear them once, somehow it's hard for me to believe that a couple of 4'' can create any 'feelable' kick... Right now I'm considering building half an mkt230, although some more compact desing with maybe one 10'' driver would better suit my needs. Does anyone know of such a design? Thanks! Cheers, Andres.

I used some P.Audio SN6-CX drivers that were on special offer from Bluearan, which are a ferrite 6" coaxial with a ferrite 1" driver on the back. They are great drivers, but relatively heavy.
If I was building 12v tops again, I'd use Faital Pro 4FE 4" drivers, probably two or three in a box on an angled baffle for good dispersion. This would be lighter but have almost the same output. You may or may not want a tweeter - they go up to 15kHz which is about high enough really, and if you have multiple units arrayed, you might even get better dispersion in the VHF than from a single horn or dome tweet. I use the 2x300 watt boards with that same 500 watt power supply. According to my measurements, they actually do 160 watts per channel into 4 ohms before going into overcurrent protect mode, or about 22 volts RMS. That experiment (1 channel driven with 1000Hz sine wave into 4r) produced a ~25 amp draw from my 4s lithium batteries, indicating a total system efficiency of only about 50% - not the 80+% indicated on the spec sheets. So they are pretty good, but not QUITE as good as claimed....

Thanks! It wasn't easy but it turned out great. I have a 500W boost stage and a 2x200W T-Amp from them, am really happy with them, although now the 2x200 (which is in reality more 2x120) are getting a little short to come along the subs. Am thinking of getting a 1x500W for the mids and using the 2x200 for the highs when I build the tops, which will be bi-amped.
Thanks man! Talking of tops... taking into account my use-case (12V, weight constrains), which tops would you recommedn to build? Cheers
