JBL 2240 in custom cabs

Register to hide this ad
Good lord that's amazing set of subs for silly cheap.

I feel bad considering the amount of work that went into them.

Unreal they are still up for grabs
 
Yeah they have been up for 20 days, and I swear he had another ad before this one. If you have the room for them, they offer a lot of bang (or boom lol) for the buck.

I’m curious about the cab size though. Is a cab that big the optimal size for the 2240? I know almost nothing about the 2240, except that it can be reconed as a 2245:)

I looked at these just because...they are taller than the 1530s I would have to hide them behind to keep the wife from killing me.
They look to be well made and I would love to hook them up to a pair of Bryston 7bst monoblocks that would really help them move some serious air. They have been for sale for a while. If you bought them, they would be yours or part out.
Course who wants 18" woofer that needs a box that big? MEEEEEEE! That's who. And they are close. Ugh.

I'd be sticking a mid and tweeter in there.

Yeah... probably not but try it for that price. I'd experiment with drivers on top of the box first. I mean the 2240h would do it but it won't be nearly as tight or quick as say a 15" 2235H... or as deep. And definitely won't sound as good in the upper bass. The 2245 is really the good one that goes a little lower than the others. But the 2240h has an fs of 30hz so probably does OK if you bass reinforcing pa speakers. Only reason I would ever consider a pair of these is if I had a pair of efficient horn speakers that rolled off sharply around like 50hz. Where it would be noticed. And these would be efficient enough to keep up. There's actually a brand new pair of 2241H here in JBL factory boxes for $100 each I thought about buying to augment my 4333As. But after research decided not to.

The finish on those is spectacular. If you have the room and want some serious thump your be hard pressed to do any better IMHO.
 
Too far for me, but ... good lord.
Swap 2245s or whatever woof you prefer in there -
The CABINETS ALONE are well worth the price.
 
With a good mid, tweet and crossover in there I could suffer along just fine with that woofer. If the woof/mid is crossed low enough.
To far for me, or I would give it a go with the Bozak B-209a mids and KLH 17 tweets in the closet.
If that don't work, just keep plugging in whatever comes along till it does.
Always got room for boxes like those.

You need to redo your research to include actual listening tests.

I have "AlNiCo 2235s" in my enlarged L200 cabinets and 2241Hs in ~7.5 cu ft in the Ethel Mermans. The 2235 goes lower, but the 2241 beats it in every other respect, especially in "tightness and quickness." Furthermore, in the range of typical rock and roll music, the 2241 gives a more punchy, far more realistic sounding bass guitar than the 2235.
 
If I didn’t already have a pair of 2242 woofers I would definitely be interested in these.

Usually there is good HiFi gear over in the Tampa area, and it seems like gear can fetch higher prices than in my area. That’s why I’m surprised no one has bought these. Maybe the WAF is just too low.

If he keeps coming down in price I might be forced to buy them though. It’s a 2.5 hour drive one way. And I have a minivan....
:dunno:
 
Given the efficiency of these drivers loaded into such large cabs, about 10wpc would be all one might need ...

Absolutely a steal ...

I don't agree fully. At least not the particular set up I heard. They were 2245s in big black JBL cabs with triple ports. My 2235H reside in 4333As. But I also think I was deterred by how large of boxes I would need to shoehorn into my home. LOL. I guess the 2235H is more to my liking. But there are too many variables like different gear being used. Maybe I'll give another listen to those 2245s.

What in the heck are Ethel Mermans?

2245's are NOT 2240's or 2241's. To assume the sonic signature of 2240 or 2241 based on what you heard from 2245's is a flawed assumption to say the least.

While 2240, and 2241 have fairly similar parameters, the 2245 has a response that is shifted downward the better part of an octave with the damping and cone mass to compliment that at the cost of several db sensitivity.

In an alignment/tuning that takes advantage of 2245's LFE, it's not going to play well above a few hundred hz whereas the 2240, and 2241 can offer much smoother midrange extension in an alignment/tuning that allows them to play down to their fs.

I give up. LOL. Buy 'em and turn them into 3-ways. What upper frequency would you cross them at and to what driver? 2440? 123A? LE-8? Something else? I'd watch that thread for sure out of interest in the 2241s here. Sounds cool if you think the upper bass is faster, lighter, and tighter. As per their current design application, I kind of feel they would be wasted on JBLs/ Altecs/ Klipsch that already have a frequency response in the lower to mid 20's. I even kind of felt that with the 2245 in triple port bins I had a chance to buy that I listened to locally. The fact that the 2241H (3 new in boxes) I saw here in the pawn shop can't even play as low as those made them a no-go for me. Hopefully that makes sense. I was onlky looking for low end extension.. no care about upper bass extension in my case. Maybe my hearing is finally going or I just need to wrestle those big, bad boys (triple port 2245s) over to my house and have a real listen with the 4333As. It's raining 18" JBLs here but I haven't made any moves. I still think the ones posted here are optimal for high sensitivity horn speakers that roll off around 50hz, There would be little overlap in frequency that way if you set the upper cap around 50-60hz on an electronic crossover or subwoofer amplifier.


.....and bowtie....what in the heck are Ethel Mermans? If anyone knows... it is you.

What i glean from Todd's posts is that they're a custom(DIY) build using a 2241 on the bottom, a 10 inch JBL for wide mid-band coverage, and a Heil AMT to round out the top. They're not unlike a favorite recipe for keyboard monitors. I bet they sound rather good with all the dynamics and extension one could ask of a single box.

Ideally, i wouldn't run any of those 2240, 2241, or 2245 above a couple hundred hz.

2240 and 2241 are generally a professional sound reinforcement woofer. But, they share many general characteristics with other heritage JBL drivers such as high sensitivity, wide bandwidth, light moving assembly, high power handling.

I consider the 2245 a professional hifi driver. With it's lower sensitivity, and 300 watt power handling it is generally not considered for professional/touring sound applications.

Myself, i wouldn't run any of them above a couple hundred hz as i'm only interested in moving air near the bottom of their bandwidth with them, let them do what they do best.

But, what do i know? i'm hardly the most dedicated JBL fanboy, although they have made, and do make some very good drivers.
 
I figured there had to be another paper driver between the 2241 and any horn/ tweeter. I'll bet those sound nice with those ESS Heils. Those are sweet sounding tweeters. I'm not a fanboy either though I do have a bunch of JBL laying around. Honestly, and this might make you puke, but for my small nearfield setup the Forte 2s are nailing it with 9 watts triode.

It's as much about how all the bits come together as it is about any of the bits themselves.

9 watts is a fair amount of power in the world of Klipsch, and Forte's are a well engineered and appreciated speaker. I'm not surprised they impress, a good nearfield setup is something to behold, it takes a good portion of the room out of the equation.
