This will be a brief introductory post today which will herald the launch of a blog/website relative to what occupies my life now.
For some time I have had a love affair with Klipsch speakers and when I used to travel around the country welding stainless steel tables together for the Chuy’s Tex Mex chain I had a chance to buy and fix many sets of speakers.
This became a passion of mine and more than wanting to just get them home and fire up something I had not heard before I want to know what could be done with them. It is a learning process and I ran across the official Klipsch forum The Klipsch Audio Community and there discovered a whole new world of technical ability and tweaks and how to’s relevant to my favorite speaker brand.
It can be a path with no end and at first I started with recapping crossovers since that seemed simple enough. With proof in hand some simple things like recapping made a real difference in what I heard I started looking more and more into restoring, tweaking and rebuilding.
A couple of years ago the trips slowed down and Klipsch started getting more expensive fast and much harder to find. It was evident that without paying trips where I could as a bonus buy used Klipsch at the other end I would not be able to buy fix and sell and show something for my time.
Now when you are a CAD and CAM guy you mind can quite easily wander over to if you can’t find something to fix what can you find to make?
The end result was a tweeter replacement for the K-77 in a set of one piece fiberglass coated La Scala Industrials I had at the time. I used an Eminence APT50 driver on my machined aluminum horn and man what a difference it made. It ate up all the shrill I objected to without me really realizing it was the K-77 tweeter doing it until I replaced a set.
This was the first version and I bought the APT50 because it was cheap and did not know better. Even so it still was a real improvement.
I can come up with ideas and designs and machine things but I am not a software using speaker and driver testing wiz (yet) with audio so while I was coming up with improvements I had no way to know precisely what was the level of improvement.
About this time a gentleman by the name of Claude Jodoin became interested in what I was doing and he did have the technical ability to analyze what I was doing and he has been a significant help since. Tip of the hat to you Claude.
Over the course of the next year and a half or so there have been perhaps ten iterations of various shapes until the latest versions which are the LMAHL V2 and SMAHL V2 tweeters.
While designing these it was my goal to offer something never done before. What I came up with was a system that would allow more than one type of driver to be mounted on the horn lens. Today I have the only modular clamp system that will allow three different mounting bolt patterns on the SMAHL V2 and four different mounting bolt patterns on the LMAHL V2. Plus the machined aluminum looks darned cool.
I have also started cutting some out of wood, primarily Black Walnut right now and these are limited to the SMAHL V2 size.
I have other ideas in various stages of design or completion and if you tag along over the next few months I will be talking about them all. I believe my tweeter retrofits are the very best out there for Klipsch speakers and they are the ONLY ones that sound this good and have superior versatility engineered right in.
I do have these for sale right now on EBay and if you go there and type in “LMAHL V2” or “SMAHL V2” you will find them. You can also buy direct from me at this time by posting a comment and I can reply to your email that way. This will save you a bit of $$$.
Bear with me I am having problems with comments showing up publicaly and I can’t figure out why. I do see all comments though and can reply. I approve them and now they don’t show up. Seems like nothing just works right the first time anymore.

Hi Dave, I would be interested to purchase a pair of LMAHL V2, no drivers needed, shipping to Europe.
Hi Dave, please send me a quote for LMAHL V2 lenses, I have the DE10s already (disregard eBay message). Thanks, Steve
Check your email please.
Hi Dave
I love that you do this. I’ve been following the Klipsch forum for quite a while and love this tweeter solution. I’m interested in the LMAHL V2. I haven’t made up my mind on drivers, but probably the DE10. I like the idea of saving some money. Can I get a price on them with and without drivers? Thanks for your help.
Depends on which speaker you intend to use these on. Where possible the LMAHL V2 with the DE-10 is the best. Here is a link to the post from the guy who tests my tweeters out on the Klipsch forum. that covers it quite well. Hey, I did not pick the name here Claude did and he is to blame.

One of the things the LMAHL V2 does is also let you use a wide variety of drivers as there are four different bolt hole patterns on the clamp plate so there is a number of drivers that will fit. That does not mean any old driver will work well but for those who like to tinker it is the very best setup out there. Really it is the only one out there this versatile. We have found nothing though that beats the DE-10 for price and out put quality.
Is it possible to just buy the LMAHL horns alone,and if so, how much are they?

I’d like more information on these. You can email me at pstores@aol.com. I am looking for them for a set of chorus I

Hi Dave, I just purchased crossovers for my seperate bass bin Cornscala project. I’m interested in the LMAHLs. I already have drivers. I see you on ebay, but you are saying I can buy here too, and save $. Can I get a price? Also will you explain what the loctite is for? You are welcome to email me:
Thanks
David
The cost for a set of the LMAHL V2 lenses is $170 which includes shipping and hookup wires, cap screws and Loctite. I will get a post up soon with prices for the others. Interested parties can email me at this blog and I can go from there.
Hey, I left a comment for you on the Klipsch forum, would like to buy new tweeters LMAHL V2 think is the right one for a 1987 pair of Cornwall II’s.
That is the correct one for that Cornwall. I will check in to the forum. By the way for those of ypu who have not been to the Klipsch forum if you search for SMAHL V2 and LMAHL V2 you will find plenty of info and feedback/comments on these. I am also in the process of cutting some mid range horns out of stacked and glued Baltic Birch and will have an article soon on these.
Hi Dave, I’d like to purchase the LMAHL V2 lenses for my Cornwalls. I have the DE10 drivers, just need the lenses, thanks!
Hi Steve, busy here so sorry for the slow reply. fieldweld@att.net is the paypal address and the total would be $170. That will include shipping by the way.
Dave, interested in buying
Hi Jason,
For anyone who wants to buy these please do the following. You can leave a message here and I will respond to you. I have been slow to update this blog because most of my time has been spent on the Klipsch forum where most people find and communicate with me. That will change soon as I intend to start updating and posting here fairly regularly.
Klipsch has been gracious enough to allow me to communicate with people there, https://community.klipsch.com/, but please be aware if you do so I am NOT allowed to discuss sales or pricing in public. You must PM me where we can talk about anything you want.
Hey Dave
I am interested in wood ones for my Cornwalls. Not sure if you did start doing mids but instead if you did. Thanks
Sorry I missed your comment but yes I make replacements in wood for the K-77 only at this time. I am working on making one for the larger 2.5cm tweeter size like the ones found on CW 2’s and up but they are not available yet. I have no plans currently for the mid horn on CW’s.
Hi Dave,
I’m interested in a pair of sMAHL/DE120 for my Heresy I to replace the original K77 alnico tweeters. Can you send me a quote please? Thanks!
Current cost on these sets is $288 if you order from me direct. I have sent you an email.
Hello Dave! I am looking to purchase the correct HF driver and horn to replace the stock ones in a pair of KLF-20s that have the K-79 drivers. I see you suggest your driver as a replacement for the K-77, but will this also work for K-79? And what might the price be?
Thanks!!
Current cost on the LMAHL’s which replace the 2.5cm Klipsch tweeter size are also $288 right now and you have been sent an email.
PLEASE NOTE EVERYONE. When I put prices here it is date relevant. As fast as things are going up in cost they will be more in time. B&C has increased driver cost 15% this year for instance and aluminum has nearly doubled in cost. End mills have doubled in cost. We are subject to the worst inflation I have seen in my lifetime right now.
FYI, I think the current prices are more than fair. Thank you very much!
Thanks for the comment.
Hello Dave, can you please send me a quote for the LMAHL for a set of KLF20’s shipping to 44256. inevercheckspam@gmail.com
Please check your email.
Hey Dave,
I need a pair of your sMAHL/DE120 for my Heresy 1 to replace the K77m tweeters. Can you let me know the total. Thanks! Connor
