I've considered building some Labs, but for the cost of parts I'm close the same price as a new LA400. If I include labour, I can buy some TH-115 instead.

You will feel it.  You will hear it, too, but might not be able to describe what is different.  To a certain extent this is one of those "you have to hear it to understand" things.

FWIW, there is a visceral difference between the JBL 4880 and 4880A subs.  The specs show the -3 and -10db freqs of each to be within 2hz of each other, but there is a palpable difference between the way they sound/feel at the lowest half octave.  The difference might not seem obvious in the spec, but they are real.

Have fun, good luck.

The written specs are goofy, the graph shows the story.

The far greater Xmax and power handling of the 2269 in the 4880A vs the 2258 in the 4880 means it can do a lot more heavy lifting.
The two are about the same at 60 Hz, the 2269 trades top for bottom.

Hi Art-

That's the graph I was looking for.  Where did you find it?

Very cool. Smile

It is from JBL Technical Note Volume 1 Number 34,

 JBL_-_Tech_Note_Vol_1_No_34_Differential_Drive_for_VerTec_Su bwoofer_Applications.pdf

Happened to come across it in the Lansing Heritige website, I think it was mentioned that it is not on the regular JBL site.

The conclusion is fun:

But what if the person wants both-Punch and depth?

I guess you can't have both. Rolling Eyes

I have 6 with Fabric Fur, and 6 without.  People really enjoy the Furry ones more.  As soon as I have some cash on hand I'm going to Fur the other 6.

I know It seems funny to a lot of the Pros out there who only like to use there ears.  But I like to point out that Tony Andrews paints his cabinets Purple and Silver for another good reason that has nothing to do with sound.  *MONEY*
 The truth is, the furry ones make more money than the non-furry ones. Weird huh?

  I also think the aesthetics of the Sh50 is something to point out. It's beautiful to look at...  One of the reasons I purchased the Sh50s was because I could instantly see the true point source nature of the cabinet. To me the Sh50 is more pleasing to look at than any other speaker on the market.

  I also think it makes since to have all those speakers in the same horn. Something that in my opinion makes Tony Andrews sweet purple cabinets less sweet. I don't like how I can physically see the separate horns for the highs and mids. For some reason seeing separate sound sources makes me feel like I can hear separate sound sources.

Sorry for my rant.

Sound is not a part of the electromagnetic spectrum. Fabric Fur is. But it is questionable.
