A buddy loaned my his Peavey bass cab a while back (118-SUB HC) which had a single 700W RMS Peavey Black Widow in it. It was probably 15 years old when I got it so my Mackie amp did it in within a year. I was feeding it 1400W RMS (bridged 4ohm) and killed it.


My buddy will let me change out the speaker but I love the cabinet. It's about a 6.5 cubic foot ported box, though I'm thinking of sealing it up for tighter response. I'd like something that can play below 30 hz, I've seen some models that only go to 35 or 40. My Mackie amp crosses it at 63hz, seems a good fit.


What would be a good 18" driver that will work well in a box that volume, and preferably under $400. Also needs to be able to handle the wattage. I was looking at this RCF sub but I don't know anything about RCF or their quality:

Maybe.

Yeah I looked at the Peavey lowmax, it's frequency response isn't great for HT subs, and the B&C driver only has 10MM of throw (if I'm reading it right) Not good for such a large speaker.


So has anyone even heard of RCF speakers?

So you want an 18" sub that will be good for HT in a 6.5ft sealed enclosure, it must handle the power of your 1400w Mackie, and be

Hey, not bad! Power handling is a little lower than its competitors in this price range, but it's a nice long-excursion sub. Efficiency is marginal, but the frequency response looks pretty good. Gonna try to find a chart for it, thanks Looneybomber!

I didn't get the impression you wanted it for HT, hence why I posted "pro" audio subs.. Sorry - my fault.


In that case - Check out the Maelstrom.

Thanks mgboy, my mistake for not being clear. I do use it as a HT sub about 50% of the time, the rest of the time is just for music and I do tend to play it pretty loud.


I've got a separate 12" Sony sub I use to pick up where the 18 leaves off, in the 60-150hz range too, works out pretty well in my fairly small room.

That ported box is probably what killed the driver. Pro boxes are usually tuned way too high for a movie LFE track so the driver unloads with the really low stuff and goes clank. Either plug the port or tune it much lower.

 

[JOHNnDENVER]

Exactly to the above... You start throwing power at any driver in this cabinet at typical LFE freq's and you are probably going to be right back to this point again in the future.



I'm pretty impressed the Black Widow hung in there for a decent period of time. I'm not a big fan of them at all, even for pro audio to tell you the truth.

There is a reason you are getting these old speaker cabinets for free these days. They are 35 years old plus (2022) and they are big and heavy like refrigerators. Guys like me bought then new back in the day, and within a few years were already antiquated. We can't sell them because they are basically useless. But you HT people seem to want them, and this is what happens.

The old Peavey FH-1s and 118HC cabinets are Not subwoofers, they are bass cabinets. The 118HC was designed to be crossed over at 250 to 1000hz and has Nothing below 80hz. The FH-1 was designed to be crossed over at 600hz and has nothing below 100hz.

Those speakers, cabinets, and power amps were all tuned to work together. A 118HC was paired with a CS800 one or two to a channel, which put out 240-watts into 8-ohms at 250 to 500hz.

When you run that cabinet below 80hz the operating load of the speaker is actually below 2ohms. If you had not blown out the the speaker first, you would have blown the amp from running it with too low of a load.

Holy crap... 14 years this one's been dead..
I think it's a record.
Nevermind.. the other thread brought back is a year older.. how many pages back would you need to go to get to June of 2007 ??

 

[Sheff37]

This is the internet. There is no age on the internet. The subject matter is more relevant today than it was 14 years ago. If you want to buy some very old heavily used gear, l have that.

And it seems a lack of knowledge doesn't have an expiration date. This reply is for someone else doing a similar google search to the one that led me here.
