| I'm buying a pair of 186's loaded with 4 ohm Omega Pros and I see they aren't well liked here. Has anyone looked at the response of this combination and/or can tell me what's so bad about them? I'm hoping these have about the same output 50-125hz as a 2x18 front loaded cabinet but only need one half the power - does that sound reasonable? Thanks! |

For the same price you would pay for a pair of omega pros (new) you could get a decent pair of secong hand drivers on hear in the for sale section. ------------- Nottingham based cab builder. https://www.facebook.com/HMAudio-154352667920145/?ref=bookmarks This account is used by 2 people. |

in other words... build your own/buy them unloaded if possible, and load them properly!
many a lesson learnt myself by buying stuff that "should be ok", dont do it

basically, there are just not as well built as different brands, such as pd's
whats the difference between a ford fiesta and a bmw? both have 4 wheels and an engine... but you see what im talking about

| oh and also, the box was designed for the pd186. so obviously will work better with that driver than any other |

So, none of yous guys actually has any experience with the box loaded with the Omega Pro? I was hoping to read what equalization it needs or that it only goes down to "X"hz or something useful like that. As I stated I'm only expecting it to be as loud as a 2x18 front loaded cab in the 50-125hz range. I do not need them to take a huge amount of power or be super flat. I have found 1978 vintage Cerwin Vega bass bins to be usable in the past and these can't be as bad as those I think  .

true that. although, everyone on here generally wants it to ound as good as possible  me included...
but seriously. if you dont buy the cabs you wanted to... build your own and source 2x second hand pd186... you could defo to that for less then £300/$400 if you know where to look

roadranger i assume you are in the USA, they will work and thats a fairly decent deal on those since you would spend around 100-120usd on materials to build them yourself and someone else has allready built them. the omega pros are not very good driver but you can swap them later.750w a bit much for those drivers but if you keep an eye on it should be ok.

something you will learn very quickly on this forum is that power ratings of drivers means nothing. that is a thermal limit not an operational limit. every speaker will respond differently in different enclosures and excursion can easily be exceded well under the RMS rating. anyways like i said it should be ok, dont expect the drivers to hold up for to long under those conditions.

| My friends regulary fried Omega 18s in Cerwin Vega L36s. They used 2 cabs per EP2500 in 4ohm bridge. Never clipped them. |
