Subject: series II P-Audio SN-12MB in X12
Date Posted: 28 May 2010 at 3:56pm
I'm finally going to construct a pair of X12's, and I'm planning to use the SN-12MB's Rog suggested in his original design.
The series I drivers are no longer made, they are replaced with the series II http://www.paudio.ro/pdf/products/SN-12MB.pdf - http://www.paudio.ro/pdf/products/SN-12MB.pdf which have a much higher AES value of 600 watts, high value for money as I can get them for around 140,- euro a piece.
I don't have the T/S parameters of the old series I, so don't know if these can be replaced without making modifications to dimension of the cabinet.
 
Anybody can help in this situation?

THey should work well in the X12

the power is not AES it's RMSCool

Do you mean the original SN12MB or SN12B mr. Smith?
Because they are not the same.
If I compare those T/S with the T/S parameters of the new one they are very different, the new type will not go below 100 hz very efficiently I think?
I have to cut my subs at about 80 to 100 hz, so there will be not much room to play with.

My mistake. I thought I had the "old" PDF in my files. I'll have to look again.

well marjan, did you test them? i'm reading a lot about 12" drivers for X12 type boxes these days..

To be honest i didnt had a time to do it. Today i am cutting some plywood for the new Bold Audio BA12 model and i will try to do spare baffles.
Problem is that they dont fit in any of my boxes. They need few mm bigger hole.

What i can tell is that they are super light, they are nicely build, but from what i can see they have very stiff suspensions and i dont think they will go very low. Not sure that they can be used in a full range box.
I expect great results 80Hz and above. Maybe they need to run in a bit. Dunno. This few days will tell.

i'm just running ideas round my head at the moment.. no concrete plans. but in the next couple of months i may put something together for something: a pair of g-subs with fane xbs, and a pair of X12 type tops, with p-audio horns and comps (which i already have), and i'm thinking over the 12" drivers.

weight wouldn't be an issue at all, so if things are more expensive just because they're light, i'd go for the heavy...

with that in mind.. currently thinking about the BMS 12S320..

cheers anyway.

You cant go wrong with bms. Comparing the build quality between paudio and bms, paudio dont stand a chance at all. I have a lot of bms drivers now having take over the complete Bold Audio production and no real comparison to be honest. Only advantage on the paudio side is the price. Not sure what the price is there, i got them for 85 us$ each.

If they're anything similar in sound quality to the 10" version they should be fantastic. The SN10MB series II is the best midwoofer I've ever heard, regardless of cost. It's quite simply astonishing when it comes the clarity of voices, pretty much on par with my Fostex FE206 in BLH in that respect, and that's saying a whole lot actually.

EDIT: And to answer a previous question in this thread, the 10" version needed about a week of run-in 24/7 to loosen up so I'd expect the same from the 12" version.

Saturnus, have you tested the powerhandling?

We trew 1100W RMS for many nights at it and it only came back for moreTongue

No, power handling doesn't really interest me that much. Pretty much any well constructed speaker can take oceans of power. But also because I don't have an amp with enough power to actually really test it. My biggest amp is 300W into 8 Ohms, more than enough for almost anything, and not big enough to damage almost any driver except some high frequency drivers with improper filtering.

Sound quality is much more important to me given that it's supposed to reproduce the midrange spectrum and especially voices.

Power handling is more interesting for a bass speaker IMO.

EDIT: Let me interject here that many people focus way too much on having big and capable sub stacks. When it comes down to it really, any speaker system without a well sounding midrange will always sound bad no matter how good a bass range it has.

this is what we have developed using SN10MB
http://www.forum.poweraudio.ro/viewtopic.php?f=47&t=10653 - http://www.forum.poweraudio.ro/viewtopic.php?f=47&t=10653
it is loaded with SN10MB , Selenium D220Ti  and PH1919 from P-audio

the passive crossover is our own design with electronic protection for the HF (faster transistors instead of slow lamps)

Hi jerronimo.
You wrote in a comment that you "SN 12 MB can get them for around 140,- euro a piece" Can you tell me where you can buy them at a such reasonable price? I want to replace the speakers in my line array system. First of all just in one and to see how it works.
