So going into mid top research, does anyone have any thoughts on sitting a pair of these on top of the 2 x tham 12's Realise it might be a bit over kill. Cant find anyone referencing these designs on the forum but the frequency response looks relatively flat and would cross over from the thams at around 110 - 130 hz. Also struggling to find designs for decent full range enclosures that aren't using 12" drivers. I guess this is to do with the fact that a 12" speaker will give a much better frequency response at around 100 - 300hz? Only thinking about smaller drivers to lower weight/size of the rig. Also, do the cubo12s go a little lower/sound better higher than the thams? I read the thams are a bit naff above 110hz. Just a thought. Cheers.

20 litre cab as on the site will take you flat to 50Hz. You may not even need the subs.

Yes, but I got the spec wrong, flat to 57Hz, -3db gives you 50.

The volts do sound lovely, however on a battery powered
system I suspect heโll need something a little more efficient than a 90dB/w
driver. The B&C enclosure posted in the link above needs 1/5th of the power the Volt needs to produce the same SPL. Edited by APW - 02 April 2021 at 6:31pm |

Yes, but it's twice the size and even with a neo driver probably a similar weight to the Volt cab. Plus it doesn't produce any bass so will need subs which will considerably increase the power usage.
For me the biggest consideration is the weight, If someone told me to pull 125kg trailer my response would be "On yer bike". The Volts would eliminate the need for subs and a processor so would allow for extra battery power and hopefully reduction in weight. It's another option. |

So in regards to the bike the we are looking at a rickshaw/trike rather than a trailer. Our logic is that rickshaws often have two people on the back so one person weighing 65kg means that 130kg must be possible. Yeah it will be tough but my friend who is a bike nut reckons its doable. Also if we go with a modular speaker design we could also just go out with one sub and full range speaker and one battery if extra transportability is needed. We have some friends who are pulling 215kg of soundsystem on a trike at the moment. They do have an electric motor on the bike and this is something we are considering at a later date. I guess my needs on this forum are kind of outside the bike side of things anyway. I'm looking for a full range enclosure that can meet the thams nicely and that has clear plans laid out already so we can just build the things and get the tunes rolling. I think designing cabs is a bit beyond my realm of knowledge at the moment but its something i'd like to get into at a later point. Im also not sure I have the time to put into getting a really decent enclosure sorted! I have experience working with audio in a studio environment so working with the DSP and getting things sounding tight out and about is where im more excited to direct my energy. Unless designing the cabs isnt that hard and you guys reckon I should just give it a go? If someone can recommend any great driver and cab combos to go above the thams that would be wicked. Or are those B&C designs suitable? I like the look of them and it seems to me as if they will crossover into the thams nicely. The aesthetic is also a consideration. I like the stacked speaker/classic rig look so this is something I'd like to stay with. If we end up building more than we can carry on the tricycle then so be it, we can transport it other ways if necessary but carrying one sub and one mid top and one battery shouldnt be a problem at all. Keeping costs down is also a consideration and those neo drivers are a little pricey. Budget is £400 max for whatever goes above the thams.

I have a pair of EV SX80s surplus to requirements. Good condition and all original drivers. PM if interested.

@ the OP ... I were you I'd be keen on those SX80. Reckon those would play nicely down to 100-120 or so. 10" and 8" (and even 6.5") are generally more optimal for vocal, guitar, KB ranges than 12s and 15s. Weight is 8.2Kg each, so 16.4Kg for the pair - and should lend themselves very well to mounting on sticks, shuftying around to suit the situation/dispersion etc. If you're not hell-bent on stereo, put both across a decent car amp channel (or bridged channels) for a 4R load - pretty much all decent car amps will work fine in 4R bridge. Oh yeah - and even if they don't work out 100% for your needs, they should be very saleable.

+1 for SX80's.
I don't know if you'e ever heard their ubiquitous 12" brother the SX300, but they were one of the best plastic speakers ever made. Just ASTONISHINGLY loud and tough as nails.
Assuming EV haven't let themselves down completely, the SX80's should be just as impressive. |

Not sure if your planning on powering the DSP off the same battery as the amplifier? But i have just been told on another forum that doing that can cause voltage drop outs. Causing the DSP to lose power momentarily.
