Hello,

My name is Dave, I�m from Austria.
I have a problem and I hope there is a person in the forum to help me.

I own two 18" speakers and I want to built two good subwoofers.

At the moment I just have two black boxes with 18" speakers, built without any "know
how".

I would like to built the 1850 or 186 horn with my speakers, the problem is that
I have no precision devices and so I want to ask you if it�s possible to built one of the cases (1850 horn, 186 horn)with another speaker than an pd.

My speakers are x-tension 18B 500, their name turned into omnitronic 18B 500, and now,
only god knows what happend to x-tension and the production of these speakers.

Typ: 18 B-500 fs(Hz): 30,9 Qms: 1,84 Qes: 0,40 Qts: 0,33
Re(Ohm): 6,7 Vas(l): 298 SPL(dB): 100 d(cm): 1320 qcm Pmax(W): 500Wrms
Preis(Euro): 285

My idea is to built subwoofers with pa-components and the power of an pa-system,
but they should have a perfect sound too.
I will built them with the optic of an high end living room system (wooden
verneer,...) and they will play in the cellar, or the living room of our house.

So my questions are:

Is it possible to built a 1850 horn, or a 186 horn with these speakers and for this use??
If yes, then which system is the better one for my speakers?
If not, which case would you choose for this speaker and this use?

I hope for a positive answer

friendly greetings from austria

Dave

Well first off the QTS is 0.33 for those drivers, so straight away those drivers would be might be suitable for the 186 horn. But the QTS of 0.33 is not really suitable for horn use, would be better in a reflex.

No I would'nt bother put those speakers in the v1000 horns(previously known as 1850 horns). The name reminds me of a cheap budget company that make dj equipment, i don't think they'll last.

Anyway you need 4 horns to enjoy....sorry matey....
