What brand/model of DSP are you using if you don't mind me asking. I am going active sometime in the future and just doing some research in the DSP models. -
What I found helpful when I had La Scalas was to drop the mids about 3 db. Then, bringing ovrrall gain up made the bass seem louder. For lower level listening, this helps a lot. The reason being most music is mixed for a certain level of playback the fletcher-munson curver menans that as your volume drops ( lower level listening), the higher and lower frequencies drop (due to how our hearing works). -
@Peter P. Thanks so much for this, I'll look into this further, my Purifi amps don't have Treble & Bass controls, I'm assuming you meant the Treble & Bass controls on my Denon X8500h AVR? I believe Purifi Class D amps have a very slight crackle when powered up which is considered normal, while it's disappointing it's not really objectionable, I was advised by the amp manufacturer that a mute relay circuit isn't necessary for 1 or 2 channel amps & is only necessary for 5 or 7 channel amps because of the inrush current being much greater, this extremely loud turn on thump hasn't occurred since, so that is why I thought it was the speaker wire ends that had a length of just under 20mm & were touching the brass housing of the binding post while it was fully inserted, I thought it may have been the issue like if it were a short, could something like that be problematic? I guess if it were a problem, the amp's protection mechanism would've kicked in to the shut the amp down & hopefully protect the RF-7 speakers. -
@jjptkd Yes both drivers have the same amount of moderate hiss, I thought that hiss is almost a given when it comes to high sensitivity speakers like Klipsch, although I don't know if the RF-7 III's 93dB spec is deemed highly sensitive, I thought that it's fairly average. I'm using a Denon X8500H AVR with the internal amps disconnected for the LCR channels for a cleaner pre-amp signal, I find it a little odd that the Denon X8500H's noisier Linear Class AB amps had little to no hiss than Purifi's 2nd Gen 1ET6525SA Class D amp which ought to have a much lower noise floor which is a pre-requisite for horns & highly efficient speaker designs. It may be possible that hiss has always been present, I just recently got into external amplification, I should add that this moderate level of hiss is only audible when my ear is close to the horn, there was hiss with a previous Purifi 1ET400A Class D amp but it was much less & I figured it's successor with a significantly lower noise floor would exhibit even less hiss not more, again this is only with my ear up against the horns, my concern is that I thought it would be much less hiss with much quieter amps.

Decisions decisions I have a pair of industrial splits and am only using the bass bins. I have different mids and tweeters, so I am not using the tops. I believe it would be a mistake on my part to separate them. Would you be interested in a full pair of split LaScala? -
I 100% agree with @mark1101 on this. If you have the patience to wait (and the necessary budget), the Heritage horn-loaded subs will be exactly what you need to give your La Scala the clean, distortion-free low bass extension that you are missing. The last detailed information we got on the subs was at SubFest in Hope back in November 2023. Roy mentioned in November 2024 at the La Scala class that all the engineering work for the Heritage subs was finished sometime in 2024. So, now it's up to marketing/production to work out when they will go into production. It will be sometime after the new La Scala and Khorn are released. Here's the info from SubFest. This is obviously all preliminary information. If Roy made any changes since that event, I'm sure it only made them even better. -
I'm fairly sure that La Scala AL6 and Klipschorn AK7 are coming very soon. No one would give a specific date at the Pilgrimage last weekend, but my guess is this will be in a time period measured in weeks or months as I saw evidence that they are already into pre-production last weekend. I can't say any more than this (and perhaps I shouldn't even have said this). However, I see no reason to believe that these speakers aren't on track for release soon. It helps to remember that the reason that these revisions are being done now is that the decades-old tooling for making the K-401 horn had finally worn out and could no longer be repaired. Since new tooling hade to be made, the decision was made to finally replace this last old exponential horn in Klispch products with a modern modified Tractrix horn. The tooling for that new horn (designated the K-406) was made. So, Klispch literally has to release the new versions since they won't be able to make K-401 horns anymore. Read my full report on the Chief Bonehead class last weekend here which has the info available to date about the new Khorn and La Scala.

Got some new tires put on my S2000 and broke them in last weekend with the opening AutoX for the year. I took the class lead by over 2 seconds. I suspect I'll get a bit faster with this thing this year. -
2025 goals. Had been wanting to upgrade my CD-DVD player. Been using an OPPO 83. Found a killer deal on a BDP-103 last month so I jumped right on it. Have wanted one since they came out. One other item on the list is to build a pair of LaScalas. Already have the woofers and lumber. Just need to work out the top end. Need to get it done. I'm not getting any younger. -
Graceful and melodic. A class act. I've listened to her for as long as I can remember.
