  • Are Monkey Coffin enclosures completely dead and gone?

    One of my favorite memories of college in the mid-'70's is Murphy drinking a beer atop a Klipsh Cornwall he put in the dorm hallway, blasting Kansas' Wayward Son. Something still awes me about 15 inch hi-fi drivers,,,

    Are Monkey Coffins kaputt???

      My system uses 15" drivers, albeit to 150Hz, where they cross to a quad of 6.5" drivers surrounding a horn. But it's true, these days some people don't want refrigerator-sized speakers. Sucks to be them.

        yes monkey coffins are no good. Need gorilla coffin to be a real speaker.
        I was tired and got tired again so now I am Re tired.

          In the mainstream, they are as dead as can be.

          Which is a shame because it's a very ideal form factor. Most of the wizardry in today's slim bookshelves and towers is the result of trying to squeeze reasonable bass response out of speaker cones with small surface areas. Monkey-coffin designs can sound good despite being low-tech because they don't need to pull those kinds of tricks.

          They still exist around the fringes... in the DIY, high-end, and direct mail-order arenas. Here's one amazing example. This is an outstanding pair of speakers you can buy today and they can often be found for less than $400/pr online. I have a pair in my garage and they are just incredible. Many have been impressed by the sound, even directly after auditioning popular DIY builds minutes earlier in my den.

          They actually look rather sedate with the grill covers on:

          Tell me if there's another speaker that's even remotely a match for this in this price range.
          • Frequency Response: 24Hz-20kHz +/- 3dB
          • Sensitivity: 95dB @ 2.83V/1 watt, 1 meter
          • Recommended Power: 430 Watts Peak, 225 Watts RMS
          Despite their gaudy appearance, they have a smooth and balanced sound, not some boosted "v-shaped" response. They're not perfect, but they're very good, and are astounding given their typical selling price.

          Also worth noting (and hilarious, given their ghetto-blaster appearance) is that these are some of the only affordable speakers in the world capable of properly handling the extreme dynamic range of some classical recordings. Very few speakers under $1K can have a proper go at some of these recordings.

            Of course, absolutely nothing stopping you from DIYing your own. There are some good examples around here; the Tarkus springs to mind. Good 15" drivers that can crossover high are a bit expensive, it's true. Some pro drivers can, although the bass tends to be restricted.

              JBL still makes some nice speakers with 15" drivers. Here's one (very good sounding) example:

                Even one with two 15" drivers. The second driver is used as baffle-step compensation below 150Hz:

                        They do, although most are clones of classic JBLs.

                          What is the minimum criteria to which the monkey coffin moniker applies?:
                          Minimum volume?
                          Minimum of a a 3 or 4 way?
                          Large (>= 12") woofer?
                          Large baffle?
                          Large number of drivers (thus helping the goal of a large baffle)

                          I suppose woofers have got "better" in terms of more excursion to make up for smaller Sd with less distortion than their 15" counterparts in the 70s? Hence the form factor / baffle profile and possible enclosure volumes have gone down as a result?

                            There's monkey coffins, and then there are kabuki speakers.

                              Small cheap speakers usually sound better than large cheap speakers, but when money is no object, a good large speaker will nearly always sound better than a good small one. I'd take a good JBL, MBL or Acapella horn over any small speaker.
