I also need to learn how to align the phase from one speaker to the next in REW.

What are your settings for crossing over the MEH woofs to the F.20s? Any measurements? How does it sound?
I am playing around with the crossover point still...currently trying 40hz. I am also running a Harmon curve. Sounds good, and def digs deep! I will be doing some mods to the setup and then retuning.

Here is a closeup to part of the temporary stand...the stand is attached to the k402 horn.

Here is a side shot..you can just barely see the support going to the front and the piece it is attached to, that is screwed to the horn mouth frame.

The speaker grill were some black mesh grills I picked up off of Amazon. The current stands are for temp use and most likely I wil design a new style from the current ones and have them made out of Mesquite hardwood.

Here is the new configuration with the f20 horns, and the MEHs setup as a 3 way.

I think it was a gain setting, problem with the mics not set properly. I used the Celestion settings Chris posted and matched the levels...which now included me having to lower the AXI2050 an additional 10db to match the OB MEHs.

The Mesquite was first mounted with screws from the inside of the horn like Danley does...once that was done we removed the Mesquite and then glued them in place and tightened down the screws. All 4 sides of the horn mesquite are glued and screwed to the horn. We did this as it is permanent. I have another pair I debating on adding the Mesquite to, but i have also thought about selling them and the Mesquite makes these very heavy. If I keep them I will use them for my surrounds.
I do not get the bass spl out of the Celestions without a cabinet, but also am not getting I the spl out of the compression driver either. I went cabinetless because I have the bass horn for 20hz performance. I was getting 20hz with the cabinet too, but I felt I a was driving it to hard, as sometimes the woofer complained. I still hit 90db on peaks when listening to my music @13' away with a passive Denafrips Athena stereo preamp. The volume works basically like a faucet...you do not get to full power until it is wide open. Wide open on the preamp is 60 and I hit 90s @10 on the volume control. Currently I am only using the Celestion woofers for the 200 to 500hz. The compression driver goes up to 20khz, and the bass horn goes down to 20hz.

Nice job with MEHs. They look similar to the modifications I did of Chris A’s design. How do they sound and measure cabinet-less?
When I made my first pair...I made them cabinetless and liked the sound, but I had lost the bass impact, so we added cabinets. I decided this time I would use a 15" horn (lilmikes f20), for the bass (I was getting 20-20,000 with the MEHs in cabinets, but on some music it was obviously being pushed to hard). I figured this way I would get the advantages of a OB in the mids and the impact of a horn. I also decided to remove the MDF panels and go with 1" Mesquite to help stiffen the horn. The Mesquite is screwed on and glued to the horn. They are Heavy....I am guessing around 150lbs each. I just got them up yesterday and today I am going to use REW to autotune them from the MLP as a 3 way.right now I am noticing increased clarity in the mids and highs over the EV DH1As.

I have the xp4080 and would like to make a high shelf for my Celestion axi2050 driver. I know how to do hp and lp, but I cannot see how to make a HS with Xilica. I read somewhere you d o it on the I put, but I see nothing for a high shelf.

I just had my f20s made with 3/4" BB plywood and then skinned with 1/2" Mesquite. (I have the recommended 3 internal braces and doing the knuckle test...they are solid. The 1/2 Mesquite added about 100lbs to each f20.

The new rack is almost done and will have conventional door frames made out of Mesquite wood with Grill cloth in the center of the the door frames. I also have 2 F20 subs that are almost complete...they are made of 3/4" Baltic Birch plywood with a 1/2" Mesquite hardwood skin. The subs should be completed this week or next...with the rack being completed a week or two later.

A courtesy PM that notified me that they were closing it, and why would’ve been helpful. Especially for future discussions (at least on my part). I’m completely new to this type of censorship on this forum. We’re discussing a 1978 speaker that somehow still has relevance. To me that is great publicity of their products.
Exactly, but they choose to just delete whatever they want...it is their forum, and we all can leave anytime and then they cannot say anything about what we post. I do not post much here since the Forum Nazis have taken over.

Haha; guess NOT
Looks like I'm to blame for this one as I mentioned horns from this "other brand."
Oops ... and "NON Klipsch" crossovers
I just made a few posts in the F20 thread and Chief bonehead closed the thread...literally a few minutes after I posted.

Tapped horns get a little ragged the higher you go. A Lascala needs a horn that will play cleanly up to the point the Lascals drops off which is high due to it's short bass horn.
I assume the same could be said of a MEH too, correct?
