only for a very short time, they were to big to be used for my most recent rig outing.
they sounded pretty good, the BMS comp driver is very loud & clear. i will have an oportunity to test them properly in March. -------------

thanks Ian. it is a decent size workshop alright, been in that premesis for over 3 years now.
if i owned the place then i would devide it up, one half for workshop & the other half for the storage of my gear.
as you can see in the pics i have to cover my rig up with dust sheets while i build to prevent everything getting coverd in a thick layer of saw dust.

| You're only looking at a few rawl plugs along the floor/side walls/ceiling to hold the batten up, or as the structure is so lightweight you might even get away with gripfill/no more nails or similar. |

i can never get an idea of how a cabinet sounds without hearing it used in its proper aplication so i stuck one of the SMT212's on top of a couple of Scoops for a proper play. the system was set up 3 way active on a berry ultradrive.
Bass
Chevin A6000 on Fane XB loaded scoops 35-130hz
Mid
Crown CE1000 (bridged) on Beyma SM112's 135-2khz
high
Audiohead AH700 on BMS4544 comp driver 2khz+
as soon as i got the balance of each component right i turned it up for a good listen.
the SMT212's reproduce the sound very accuratley & clearly, the fact that the 12" drivers are not completely horn loaded gives them a very 'hi-fi' sound.
overall volume was very good as well. the one cab had no problem keeping up with a pair of scoops, could even go to a ratio of three scoops per SMT212 (depending on the style of music played) & it would still have sounded nice.
to be fair i think the only week point in the chain was probably the Crown CE1000, there are much better amps available for running mid.
my amp of choice (C-Audio Pulse 1100) decided it would keep going into protect mode, rather than play so the crown had to be used.

thet are very loud & clear, the BMS comp is very efficient (113db) & the beymas are very powerfull. i use a C Audio Pulse 2x1100 on the beymas because i need alot of power at 4 ohm. the cabs are ported wich alows them to get lower than alot of mids, i guess 120-130hz. -------------

Firstly cheers Static Age for the info on the Private message... & sorry to bump an older thread One thing I've not seen is a recommended Horn for these cabs? What dispersion horn are you running here? |
Posted By: Static Age
Date Posted: 30 September 2009 at 10:02am
|
The horn used in the pics is 90x40 degree dispersion. However my SMT212's have changed a bit since I made this thread.
I'm now using the BMS driver on a smaller 60x40 horn & a EVDH1 2" driver on a large JBL horn.
I had to modify the cabs from the original design to make this lot fit.
The EVDH1 covers 1khz to 5khz & the BMS does 5khz & above. I'll get some updated pics of the cabs up & the model of the JBL horn.
Edit: the JBL horn is a 2380 90x40 deg dispersion. -------------

The 12"s play well from 130hz to 1khz, I will have to have a play to see exactly how low they can get. I think i used the 112W. Though if i were to do this project again from scratch I would definateley use neo drivers.Mine being four drivers per cab are just so heavy to stack, thanks to the EVDH1 they are so top heavy that if you want them up high it takes a 3 man lift to do it safely.
Like I said earlier I'll get some pics up asap of the additional work I have performed on the cabs since I first built them.

When did the http://www.bluearan.co.uk/index.php?id=BMASM112W&browsemode=manufacturer - - Beyma SM112/W come about then ?
Static, I think you actually used the http://www.bluearan.co.uk/index.php?id=BMASM112N&browsemode=manufacturer - - Beyma SM112/N , I remember looking at them too when I heard the price was 66 quid, but have since gone up more than 20 quid now!
Remember this...
The W-Series seem to be up their with the higher spec drivers @ over 110 quid but I can't work out the main difference. Anyony ?
Btw, looks like the 'N' does not stand for Neo in this case!

wow 10/10 for memory Tekasis
When i got the beymas they were not in the original boxes & I havent seen the back of the drivers since I fitted them in the cabs.
Indeed the N in the Beyma model number does not signify neo. But I stand by what I said, anyone thinking of stacking the SMT212 over head height should seriously consider neo drivers.
Lucky for me I have plenty of people on hand to help with stacking. -------------

As promised here are some pics of how the cabs developed.
I had to do a proper job of fitting the large JBL horn & EVDH1, this meant putting in support for the EVDH1 as it weighs 10kg. To do this properley I had to build access panels in the tops of the SMT's. The cross over between the EVDH1 & BMS is a link dynamics unit, cross over point is 5khz.

That looks fantastic Static!
What's the difference in sound compared to what it used to be ?
Is the EVDH1 a 2'' comp ?
Have you tried listening to the cab without the BMS connected ? & with it connected can you really hear more sparkle ?

Thanks. The main difference is the SPL in the upper midrange 900hz+. The original SMT's were fine when used above 4 bass cabss but the upper mid sounded a bit flat when used above 8 bass cabs. the four 12" really make a noise when driven hard by the pulse 2x1100 but at these levels I started to here a gap between them & the 1" BMS. Dont get me wrong the BMS is probably one of the best 1" comp drivers I have ever heard but I was concerned that driving it hard down at 1.2khz that I would blow it.
The DH1 is a monster of a 2" comp & it can get as low as 500hz on a big enough horn.
the BMS gets upto 20khz so I'm sure without it I would notice. Though hopefully this weekend I'll get time to do some testing with the cabs. I'll run them with & without the BMS & I plan to see exactly how low the 12" will go.
Here's a copule of pics of the EVDH1 so that you can appreciate the size. Down side now is the weight of the SMT's, I'll see if i can weigh them to see exactly how heavy they are.
I have the EV Spec sheet for the DH1, I'll link it up tomorrow.

Awesome development there Static! Anyone tried the Eighteensound XT1464 elliptical HF horns? I'm keen to match 12ND710 in the 12's with this horn & a Beyma CP755Nd on my SMT212's |

Its probably driver dependant but I could get mine to sound ok down to 100hz, probably helps alot that the 12" are in a ported reflex chamber rather than sealed. -------------

Pictures please  .How did you go about working out dimensions, did you just 'cut' the plan at the half way point?

"Those JBL horns are similar to the EV HP 940s only difference I can see
is the EVs have a wave guide built in the exit throat" The EV HP940 is quite a bit wider than the JBL 2380, but it does sound better that the JBL. The EV HP640 sounds quite a bit better than either, but is even wider. ------------- djk |

so.. looks like im going to start building a pair of these in the next couple weeks. to clarify... its ideal to use the sm112N and bms4544. i cant seem to find the bms 4544,s nether can i find a cut sheet for me to have it cut for me as i dont have the space or a table saw. if the bms 4544 isnt easy to find or is too expensive, what else would work well against the beyma sm112n? thanks

Posted By: AM55
Date Posted: 28 October 2013 at 8:43am
|
What do you class as a sensible price? Sub £100 per driver? Sub £50 per driver? B&C 12PE32 is recommended, PM TonyASS for as sensible price as you are going to get on a brand new driver. For HF, I would stick a 1.4"/1.5" in a duel 12. Maybe just ask in the wanted section or again TonyASS will do a good deal on B&C. Forte Audio do BMS at a good price. Depending on if you are using 1 cab a side or 2 cabs a side will dictate horn type again Forte Audio do Faital Pro horns at a good price, TonyASS will do B&C at a very good price or you could ask in the wanted section for used.
