search the forum for usb, make sure you go to advanced search and set to any date, hd15 are probably almost as good. 4 hd and 4 labs make a good combo if you dont need a helluva lot of kick, just add mid his lol.

I was originally planning to do Labs and HD15s, but I wanted to go to the forums for advide on what mids and up would go well - of course as a DIY plan that I can get somewhere online...

Maybe I should make a seperate thread? Also my searches are getting spotty results and contradictory opinions, which is why I started a thread. On most topics I can get the info I need on just about any forum out there, but with anything DIY audio, strangely enough, you run into more opinion than fact.

This is always going to be the case because 1) people have heard and favour different equipment 2) Peoples ears and therefore opinions differ 3) A lot of people talk from simulations (myself often included) and others who have built the cabs can speak from experience

I havent heard the USB but the principles are the same as the HD15 they should go a little lower although how useful this is when the labs easily make 80Hz is debateable, they MAY give more output due to the 18"s vs 15"s but this is debateable since I have not seen a plot for the cab. They MAY be a little less hard on the cones than the HD15s as a lot of people have torn drivers by pushing them too hard or not using the recommended PDs

What is for sure is that the USBs are larger than the HDs but have the same front profile as the lab meaning they will match up aesthetically if thats important to you.

hd15 [well 215] has same frontal profile too, well its not as heigh if stacked horizontaly, but from the front the difference between a usb and a hd15 from the front will be millimeters....
ie hd215 also stack the same....

actualy, seeing ninebar used 12 labs and four215, im actaly thinking that x-tro and lab for dnb might be an idea, howether, to stack properly youd need either 6 labs and 4 x-tro or 3 x-tro and 4 labs. [need to splay the x-tro]
but i suppose if you dont mind running l-c-r mid hi then 3 and four may work, just a thought.
im not saying definetly go for lab horns, but i am saying that for what it sounds like your after they will certainly do the job, and personaly i realy love them....

Hahaha - on another forum I got "is this guy an idiot?" response when I asked if there was another subhorn design that would work more efficiently than LABhorns, or whether more efficient or not - what's the best for DnB. What's your opinion on this?

Also, what would you use for Mid-Top design in this config?

afaik there isnt a more efficient well known sub horn that plays as low as a diy option....
personaly id be torn between something like an x-tro or just a hd type kick bin and maybey an mt12" low mid and 6"and 1" upper mid hi section.
its ll personal preference lol.
4 labs four hd [or2 usb] and er maybey a pair of porn horn mk2 would be ace, im guessing as you play dnb you dont want a helluva lot of mid hi, well you do but bass is much more of a priority spl wise....

I think the thing that works against the Xtro in this case is its scaleablility, you cant really do more than 1 xtro per stack without getting some disgusting combing. The only way to make it work would be to lay xtros on their sides but you need a high enough stack to get them at the right height.

There are plenty of designs knocking about Boukisan - Billfitzmaurice.com has a whole site worth of them and the Tuba 36 would probably give a similar load of bass to the labs if you use enough of them.

My only quarms with the lab are

1) its only suitable for 1 driver - if that goes out of production youre f**ked.

2) Without the alu heat sinks on the access panels I hear those drivers tend to get a bit hot

I think its proof that the lab is far from perfect. The designer now makes only tapped horns.

This is a good comparison page of the T36 and Lab

This does in no way quantify what the cabinets "sound" like, or their power handling, however what it does show is that there are other designs that do similar things. Im not suggesting you build one or the other but the T36 is going to be cheaper and have more flexibility in driver choice

I'm not worried about the heatsinks - I've actually got some ideas to improve them, and I would then have my design machined by a friend.

{removed question that was answered in previous post}

Having trouble finding plans for Porn Horn MK2.
I've seen Porn Horn as a commercial design, can't seem to find in in the plans section on speakerplans or on the forum...

not diy [porn horn] howether os similar ish to mt122 .....
er by the x-tro i meant something similar,
hmmmm thoughts running. decide on your sub and kick section then we can look at mid his...
also have a look at martin 215 on kick duties, a pair should be more than enough kick on top of four labs if you play dnb.........
im not recomending the 215 as a definetive desicion just another option....
