Not stuck but enlightened choice. Still not catching our drift?
you can start a thread of your own to make fun of what ever you want but that's not what you want to do. Shu started a thread to have discussions with others on the topic. If you are done now leave. Keep posting more of the same and you just show others what it is you really want. I mention this because I am reading post on other forums about problems here at the Klipsch forum. Respect is a two way door, to get it you have to give it.

Very sorry to hear that you lost your Dad. I am happy though to read of your memories and to know that his system will carry on with you. Welcome to the forum.

A week from today my brother and I will be heading to a resort in NW Wisconsin for a week. I thought it would be fun to have another giveaway!
First prize is a pair of metal Klipsch Professional badges. I got these years ago from a forum member but ended up not having any use for them.
Second prize is the digital code for the new Jurassic Park Dominion movie, 4K version.
For the first prize, guess how many panfish (bluegills/crappies/perch) in total that we keep.
For the second prize, guess how many largemouth/smallmouth bass (combined) we keep.
That's it! One guess per member and please, if you won anything from my previous giveaway let others have a chance. I'll post the results when we get back.
Good luck!
16 fishes.

As a teen my first commercially made loud speaker was a pair of Altec A7 with 811B horns. Check out horn loudspeakers by JBL the Master Reference Seven Series and Danley Sound Lab in North America.

The double set of binding posts are actually so you can split the two crossover sections and drive them independently, tweeter and woofer and then you can run them with a stereo amp. Two identical stereo block amplifiers are what you want to use so they match in both sonics and in gain. Run one stereo amp per speaker channel. So the first stereo amp would be connected with one channel to the woofer section and the other channel to the tweeter section both channels being fed from your preamp out via a splitter to the amplifiers left and right inputs. Same arrangement for the other channel. Hope this helps.
just so we are all on the same page the preamp output for the right channel is sent to the stereo amplifier which will drive the right speaker. That right channel signal will be split using a simple one input to two output splitter which is then connected to both of the inputs of the right channel stereo amplifier. In this way you will feed both of the two channels of the stereo amplifier driving the right speaker with the exact same right channel signal. Running identical stereo amplifiers insures that both of the drivers in each speaker are in phase and are exactly level matched.

Thank you for your reply. I already have a older pair of Jubilees. But I'm not sure where I can hear a pair of JBL M2s in the Austin Texas area. They are hard to find locally.
If the JBL M-2 speakers are discernibly more accurate than the Jubilees, I would be willing to make a change
jubs are more dynamic than the M2's and to me that would be of greater concern. Without hearing both you just are not going to know which you will be happy with.

I recently picked up a mint pair of JBL Sr4726a series ll speakers along with a pair of as new JBL 2226j woofers. These are for my brother. There was a follow up model of the SR4726a which used the 16 ohm 2226 woofer along with the same compression driver and horn as used in the SR4726a but with an upgraded crossover. Can anyone remember the model number of the later speaker or have a schematic for the crossover? I would like to upgrade the SR4726a speakers to the newer crossover in hopes of improved performance. Thanks for any help.

They aren't plug and play. The K-63 uses a neo magnet and weighs 4 pounds. The DH1506 are 11 pounds each. They will crack that horn lens unless you build a shelf for them to sit on. All this is detailed in the thread referenced above "Epic Owners Group." Highly recommended reading.
While I had the box apart I built a shelf for the 1506.
I damped the horns with pure Silicon caulk, an 11oz tube per horn lens. Cost around $6
I braced the enclosure
I added about 2 pounds of Fiberfil to the bottom where the ports are. I took out the two 1.5" foam sheets from the bottom only.
When I added a 15" sub the CF-4's had a sound with more accuracy and more dynamics than my La Scalas, more than my Khorns. The little improvements added up into a big overall improvement.
you are right with a caveat, you can plug them in and listen and decide if you love them or not then if you want to to keep them you will need to support them. People tend not to listen and be lazy. You should not ship a KLF20 or a KLF30 with the mid motor in place either as it is heavy enough to break/snap off from the horn if the box is given a good shake. This is kind of the same with the EV DH 1506. If you don't shake them or drop them or move them not problem but they do need a shelf or a brace or a hangar to hold the motors weight. Great driver the DH 1506, like Bob Seger said "like a rock".

Altec A7 with 811b.my first store bought speakers, I wanted but could not afford a pair of Valencia with 511b horns

EV DH1A drivers are true S.O.T.A. compression drivers, there is nothing else like them and the more compact Neo motor versions which use the same diaphragms.

So that brings me to ask two questions.
1. You mentioned "diffusor up in the top of the cabinet which is a good thing (so will any installed brace work)". Would what I'm proposing as additional bracing also be a "good thing" with these P.R. boxes?
2. Should I add the ferrofluid to the diaphragms?
Thank TimBo
some brace work is going to be better than no brace work, this is minimal so don't expect a big difference.
ferrofluid can have more or less impact upon driver damping (internal resonances) depends on the driver. The correct viscosity would be required and you don't know what that was so you are in the dark. A generic shot in the dark will at the least provide some extra heat transfer. Get some and try it, if you like it leave it in if you don't remove it.

I'm considering one. I've seen your posts and you clearly are very experienced and have listened to a ton of gear so your 'my forever amp' carries a lot of weight. Could you offer some insights into it's sound character and how it compares to other amplifiers you've used? I'm running Modified Khorns with volti mids bms 4592nd drivers and fostex t500a mk3 tweeters.My only trepidation is $3k for a 12lb amp, lol.
It is light because it uses all top quality switching supplies. I compared this to a 68 pound 200 watt per channel Spectral and the AHB2 was much more powerful sounding with deeper more impactful bass able to play much louder with more control and composure when com[pared to the Spectral. If I were to describe the sound of the amp it is very neutral very open and spacious sounding but not one of those juicy wet sounding amplifiers it sounds sweet when it is called to and not so when it is not called to. The AHB2 is not a second harmonic tube sound. Theses are my opinions and like everybody else like elbows we all have at least a couple. You should go and have a listen and see for yourself what you think. It is very reveling of associated gear so if you don't like what you are hearing look up stream for the possible issue. I hope this helps but in the end you need to make your own evaluation.

Why don't you have a look see for a pair of Peavey FH1 cabinets, it's a better horn and a better cabinet (a tiny bit larger). It's not very likely you will beat the $200.00 price but if you can find them local that would make all the difference.

RIP Dave and condolences to the Mallette family.

You can do whatever you want to do to your klipsch speaker. The speaker was designed and produced with a certain spec in mind. Once you put in something that is not klipsch approved then it is no longer a klipsch speaker. I really don’t understand why this is so hard to comprehend
The first 47 characters say it all thank you, "you can do what ever you want to your Klipsch speaker".

New tweeters from @Dave A made a large improvement to my system. They made the highs sound a lot cleaner, so much so that I bought a second set for some other speakers.
https://www.ebay.com/itm/224152702930?hash=item34308acfd2:g:6jcAAOSwBF5d5TWS
that's reproducing harmonics only everything over 6KHz. now imagine if you improved all the fundamentals and upgraded the mid?

Those horns should never be shipped with the drivers mounted to the horns. you can repair them.

the measurements in this review were made with a state of the art klipple non acoustic measurement system, I thought that if you had not seen them already that they would prove enlightening.
