I bought 2 drivers (eminence kappa 15c) for a super MWM build. Felt I could do a decent job after what I learned from the pair of f20 subs that I built. As typical with life, I’m trying to finish a degree and we’re finishing our basement for extra living space. Hoping to do a build this fall/winter. Already running the K402’s on Peavey FH-1’s.. I’m halfway there!

@MookieStl, my avatar is something inspired from a pressing of Pink Floyd’s Relics album. I was always mesmerized by its weirdness as a kid and only found out later that it was a bottle opener. I’d kind of like to have one but have been to lazy to seek one out. Production began in the 1930’s by Wilton apparently.

Awesome! A big improvement with my La Scala’s was when I added a second Klipsch ksw-12 subwoofer. Horn loaded subwoofers blend very well with the La Scala, the f-20’s were a large improvement over the ksw-12’s. As CECAA850 mentioned, BFM has the Tuba HT to consider if you haven’t checked it out already https://billfitzmaurice.info

Using the Dayton RSS 390 HF, which others on the forum seemed satisfied with. Powered by a Crown XLI 2500. I am not pushing them very hard but I believe I could break my windows if I tried. I would be interested in the lilwrecker as well. Have you looked into plans for the Danley spud or DTS-10? Schu’s suggestions look like beautiful builds that complement the La Scala design nicely.

I’ve been very happy with the two “lilmike Cinema F-20” subwoofers I built this winter. Others on the forum have documented this design in the subwoofer section. I am a novice woodworker and the plans were simple and easy to follow. MiniDSP is the crossover I use.

I recently experimented with this. Used 1/2 ply from a big box store and some 2x2 as bracing. Not as elegant as Greg’s as I’m a beginner with woodworking. Our placement for K horns is less than ideal but the fiancé and I both agreed we gained some low frequency response. If I were to build another pair I would use 3/4 ply.

1979 K horns in living room- vinyl, & streaming 1982 Cornwall’s- Dad borrowing- vinyl & tuner 1984 Heresy’s w/two KSW15 AVR duty (WAF) 1990 La Scala’s in man cave- vinyl & cd’s

Had a chance to compare Stock AL-3 (recapped with Sonicap's) networks and Crites AA networks. Have you had made it to FL yet? My impression, AL3's have slightly less midrange and found the AA's have a snappier high frequency response as well. I prefer the Crites AA's over AL-s, but also prefer Crites A/4500 over the AA. I have not heard a standard Type A network. My speakers are loaded with stock K-77M tweeters and K-55M Mid drivers, and K-33 woofers.

I have AL-3’s in my 1990’ish La Scala’s with original drivers. The networks were recapped by me (were original upon my purchase) with sonicap caps from Crites. After listening to them stock for around 3 months, upgraded to SMAHL tweeters with B&C DE 120’s, as well as the Type A/4500 network from Crites (time aligned á la Marvel- tweeters mounted to lenses placed on top and to rear of the La Scala). The sound was somewhat jarring at first, but after a/b testing (no measurement equipment, just ears), I really liked the Type A/4500 with DE 120 combination. Eventually, I went with a Volti 2” horn with ALK Universal Networks, keeping the La Scala bass bin only. A great deal on Peavey FH-1’s came up and am now using the ALK Universal, DE 120, Volti 2”, FH-1 combination. Did some A/B (again, no measurement equipment, just ears), with the brother in law between my current setup and the La Scala’s- the La Scala with AL-3 did very well against my current setup, although a bit more compressed sounding to my ears. I know I didn’t answer your question regarding Type AA’s, but wanted to share my experience using AL-3’s.

Exciting progress, keep up the stellar work!

Thank you for keeping us posted, really enjoy watching the progress.

Looking great, thanks for posting!
