Many years ago I had the pleasure to spend an afternoon with a pair of the Interlude IL40 towers from Infinity. I was generally impressed with their performance, especially the bass quality. I always thought about buying a pair now that they are down in to the $400-600 range just to use a reference to judge my own builds against but decided against it as storage of tower speakers is just a pain in the ass.
Anyways, Iaell (IL) is an Infinity Interlude IL40 tribute build using OEM CMMD drivers from Infinity. The woofer is a direct pull from the IL40 - the midrange is actually from their Primus line but is nearly identical to the actual midrange used in the IL40. The Interlude IL40 is a floor-stander - these are large stand-mounts. The IL40 uses a small dome tweeter, these will be using the Fountek style ribbon tweeters sold as GRS brand. I am pretty much a ribbon guy these days. Call it a throwback to the Emit days if you like. Overall, not a lot of real similarities other than a couple of the drivers, but this is a tribute not a clone.
Driver information can be found here:
Here is the woofer model (1.2 ohm series resistance, I will be using air core coils as much as possible in this build). You can see it will be capable of playing very low - F3 of 30Hz is nothing to sneeze at:
CAD drawing of cabinet and internals (gonna be a big boy like O'Ryan):
The drivers measure well enough that there should be little to no problem hammering them into shape. Until I get on baffle measurements, I am going to tentatively target 400/3500 crossover points.
This is an exciting build for me (with a streak of nostalgia tied up in it) and will serve as a rotation pair in my main listening space, sharing time with O'Ryan - which is currently out of rotation in favor of another pair right now).
