Architect7 both mids and mid woofers are from the Illuminator series.

DJN I wish they only cost $800 by time I got the AM model landed they were close to $1000 ea, but I don't regret the purchase for a second I love the RAAL tweeters.

I have heard the Heil and to me there is significant difference, especially when used with a decent active Xover to let it reveal everything.

Here is what I did with my ESS cabs. This write up is from April 2005 over on AK.

My ESS E-waves are complete. Here is the story as it unfolded. I only bought the ESS AMT 1Cs for the Heil tweets and planned on baying the rest of the bits….but then I started reading the Econowave thread and I was a goner.
Here are the ESS’ as I first saw them (paid $200.00 for the pair) notice the missing PRs and crappy grills.

I put the wave guides on top, after taking off the Heils just so see if they had promise….they did, in scads...and that was with the original ESS crossovers!!!. After ginning up the crossovers (thanks for the parts Bauhausler) and sticking them on top as well as the horns just to see how they sounded I was floored, and, that was without the replacement PRs. Urizen PMed me offering a pair of unused PR kits for a very reasonable price (thanks Urizen), so I tore the cabs apart and repainted the black parts and sanded and restrained the wood veneer, (thanks for the stain Kegger)

I also recovered the grills with a sheer black “speaker cloth” from Jo Anne Fabric (that is what they call it and that is what it is…..$20.00 for enough to do 3.5 grills). I cut holes in the back of the cabs for the double speaker post plates and mounted them. I redid the PRs and put them in, and mounted the horns and crossovers.

I started out with the lower eff version of the crossovers and because I ended up bi-amping, I did not need the reduce horn signal so I just swapped out the parts ( R1, R2, and C3) and I am now getting much more SPLs out of my horns. I then (upon Kegger's suggestion) took C2 to 6.3 vs, the 12uF it calls for on the schematic. That brought up the upper vocals in the woof and just filled in the area a bit. At first I was running the woofs with an Adcom GCF510 and the horns with my 300B. Kegger also brought over some of the foam he is using in the throat of his horns and scupled plugs for mine. Those make all the difference in the world. You can crank up the volume and the highs sound just as good but with no extra sharpness. The bass was unbelievable…way down to the lowest bass note without rolloff, the mids were as clear and dynamic as you would expect from horns with ABSOLUTLY no horn sound. The high are sweet, sweet, sweet. After a while I started feeling fatigued from the bass so I took out the Adcom and I am now running the 300B on the woofs and the Decware Zen on the horns. The bass is just wonderful so detailed and creamy to the ears and if you want to crank it, it will punch the breath right out of you. The horns with the Zen amp sound very rich, detailed, and present. Here are the finished products. Actually I still have to redo the other grill but I am waiting for a larger time window so I can make a picture tutorial to post of the web. It took me three hours to figure out how to redo them, but once I figured it out, it went smooth. The top of the grills had a piece of thick cardboard in the recessed top but I am going to replace that with glass so I can show off my crossovers.

So thanks to Keg, Urizen, Bauhausler, and all of you who took the time to perfect this project. Cheers.

here is an up to date picture of the speaker, with the SEOS waveguide.
the waveguide does have an off-axis null at 14k, but i guess that doesn't really matter too much.
the added boost below 4k is really nice

Hi! I finish the project with acoustics ESS Tempest LS-5. It was necessary to arrange an impedance. I removed to me on other party of the ocean. I came in a disgusting condition. I redid registration, now it is acoustics of a tornado. VCh very wide reproduce panoramas.

No, it is new acoustics. The closed type. The loudspeaker is fixed as on the picture, the phase inverter isn't present. Instead of the phase inverter two helicoid channels. Fillings any sound-absorbing in speaker systems aren't present. Sound real. Bottom fast. The group delay is minimized to the maximum. Acoustics of new generation. The author this acoustics called the Tornado. It on pictures of a tornado it is made on the basis of known speaker systems, in native boxes, with my alterations.

John, if you are going to make the Tornado, I will be glad to help with consultation on this matter. Sound.... The sound you so will surprise that I think phase inverters remain in the past. My English limps a little, apologies I ask for it. But an essence that there is a new acoustic registration which began the procession and believe its birth this powerful addition to known today in a sound. I will be glad to help with a design.

Kirill.
