Just bracing above & below the passive/woofer will make a BIG difference in the cabinet rigidity. Here's how I braced mine. (& it was fairly easy)

Nope, didn't change it any because they're made for car subwoofers & are designed to not block the bass. I also specifically chose the neodymium magnets (not regular magnets) to hold em on super tight w/o rattles. I considered velcro, but I like the fact that the magnets aren't really attached to either surface (IE: grill or passive frame) so they can be removed in about 2 minutes by pulling those strong lil suckers off 😄 IF you chose to try it yourself, make sure you buy metal grills, not plastic so the magnets stick. These are the ones I used, & fit the Quartet & Forte 1's EXACTLY. https://smile.amazon.com/gp/product/B083R3RBG1/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 If you have Forte II's or Chorus II, you would need something similar, but in 15" size

Major SCORE for that price! I have 2 (loved the 1st one so much, I bought a spare) I paid about 250.00 each for mine. The 115 is underappreciated because everyone chases the 117. With Klipsch, the 115 is plenty. My Chorus will vibrate CD's out of their storage rack at 1/3 volume 😃

My mains are a set of Chorus 1's that I modified with 7" port extensions & internal bracing & are fed by a Yamaha M-60. They'll blow these puny Quartets away 😂

Maybe they don't need it since they're a little smaller, but bracing made a big difference in my Chorus 1's. It'll only take me a few hours & we all have time to spare right now 😂 Plus, I wanted to rotate the woofer 180 & redo the gaskets/seals for the woofer & passive so I might as well brace em while I'm in there...

I/He will ! & since I will re-inherit them someday (my Dad is 82) I'm doing them like I want em before setting them up for him. I just sent the crossovers to Mr. Crites for a recap, & I will be internally bracing them like I did my Chorus 1's. ( 🤣 Probably post another thread over in "Technical/modifications" when I get everything done)

Grand-kids, & their friends 🤪 I've seen MANY pushed in center dustcones on all three models (Quartet/Forte/Chorus II) Once they're pushed in it's VERY hard to undo.

And finally, the magnets I used (in case anyone wants to duplicate the idea)

I like my modified Chorus 1's so much, I recently picked up a mint set of Quartets (Chorus's little brother) so I can set up a music room for my Dad. The rear passive radiators are both perfect, but I was worried they wouldn't stay that way forever... After alot of thinking, here's my "fix" : Ordered a set of metal car audio subwoofer grills from Amazon. 2 packs of small neodymium disc magnets from Ace Hardware. A pair of knockoff (IE:fake) Klipsch pie logos from ebay I think they look awesome, I even like em better than before! The cool thing is the magnets are just stuck to the passive frames & the grills are then stuck to the magnets. They grills came with a piece of rubber/trim which helps them not grab the magnet too tight for easy removal (neodymium magnets are CRAZY strong) The Quartet's have a 12" passive & I checked specs on quite a few grills before I found a pair that were just right & fit the factory cutout EXACTLY. They really look like they were made that way 😃. The same concept would work for Forte's & Chorus II's if you used 15" grills.

If you REALLY want to hear those cannons, get a copy of this Telarc CD. They're unbelievable & will scare your friends if you crank it up 😁

Get the "Crites" titanium diaphragms for a MAJOR sound improvement for minimal $$$. If you're worried about them sounding harsh, they won't 😃. If you want to do more, here's some ideas

Try some KSF S5's. They're on Ebay alot. They come from the early part of the "synergy" line, which was many years later than the Heresy II. But believe it or not, they sound great together. Small, efficient, & disperse sound well. (I have both in my 6.1 setup)

I sold my La Scala's after I modified the ports & internally braced my Chorus 1's (thread is on here) I listened to both & in the end preferred the "impact" (in my chest wall) of my Chorus 1's at higher volumes... A year later, still no regrets! 😎 I say it's a lateral move at best (but try em & see)

Thanks for the + review, & YES I'm still enjoying my Chorus 1's. I actually sold my La Scala's afterwards & have ZERO regrets (may shock some to hear that...) I actually think my Chorus 1's sound better in my listening space. (& searched for Chorus 1's & did the mods so I could put em flush against the rear wall)

This one is the correct "Build" thread, the thread you linked I was still asking ALOT of questions myself 😎

I'm the one with the "other" Chorus port mod thread, & I would ABSOLUTELY do it again !!! I bought a test tone CD just to have a measurable before & after reference point. (info is in my earlier thread) & mine went from being able to hear a 45 hz test tone down to a 39 hz tone after the mods... That may not sound like alot, but trust me it's SIGNIFICANT difference when listening to music. "Six Blade Knife" by Dire Straits will put a palpable thump in my chest wall across the room & knock stuff off my shelves 😀

Pic that shows them "out of the box" looks downloaded from the internet to me... Probably a gamble to buy them sight unseen. I Check here (goodwill online) usually just for fun, because alot of the time things get bid up to where the "deal" is no longer a good deal. Trust me, these will go WAY up as it gets close to ending 🙄 Dave

Even better 👍 (? forum member) Congrats on the sale too cause I know selling a "large" heritage single can be tough...

Cool, pretty happy over here too. I finished up my Chorus project (build thread in Mod forum) loving them too & glad my "firstborns" went to a good home 😃

Speaking of your HT, how'd those La Scala's work out? Dave

More testing, Using Digital cannons & they sound AWESOME !!! You better be SURE your equipment is "up to par" IF/when you crank this version (Telarc) of 1812... The cannons are around the 12 1/2 minute mark on track 1 & they will definitely test your system, your hearing, & your chest cavity for you 😀 (& you may get PTSD)...
