Why HiFi manufacturers don't make active crossovers anymore?

I have been enjoying an open baffle WMTMW 3-way (my design) using a DEQX HDP-4 for a few years. A great option, especially if you like to tinker. Check out their website for some features that set them apart from others. All other design variables being equal, a fully active speaker sounds (to my ears) better than the pasive version of same. Also amp rolling can be a fun journey (if a bit expensive). Ex.. use an iron fisted ss amp for the woofers, tubes for the mids, highs.....or vice versa......as you prefer the sound. Just play around, you might find some pleasant surprises.

Hi @closenplay

Very interesting combination of features!!

Is it a traditional enclosure otherwise, or open baffle??
Best,

Open baffle. 15" top/bottom, 10" planar magnetic mids, amt in the center. Baffle is sandwich of 3/4" ply, 3/4" mdf, 3/4"ply. 72" by 19".

Hey phusis that is a nice looking setup and I have heard good things about the lilmikes.

Thanks, mahlman. Lilmike has made some great subs. Initially I considered a pair of the Cinema F20 FLH’s, but wound up being invested in the characteristics of tapped horns instead, also thinking about building the LilWrecker TH’s which are tuned some 5Hz lower than my MicroWrecker’s. There’s no free lunch, though, as they say; a 5Hz lower tune in this case eats up about 5dB’s of sensitivity, further limits the usable upper bandwidth, and turns them into 30 cubic feet or 850 liter monsters (the MW’s are 20 cubic feet per cab - not small by any stretch of the imagination). I also considered Josh Ricci’s Gjallarhorn tapped horns fitted with an 18" driver, but they’re huge, and the driver they’re build around, the TC Sounds LMS Ultra 5400 (weighing in at a ludicrous 80lbs) can no longer be had. Lastly I very strongly considered Ricci’s Othorn, fitted with a B&C 21" driver (the 21SW152 - a beast) and indeed the runners-up to my MW’s, but budgetary constraints mainly had me favor the MW’s.

What drivers are you using on the top section? I have a rebuild LSI bass bin I am thinking of making into a two way with a 2" compression driver for 500hz to 18khz . Are those Fastrac horns and were they made from stacked Baltic Birch? I have a CNC mill and I an thinking of making some mid horns too.

Midrange compression driver in the Uccello’s is the B&C DCM50, and the tweeter is the DE10 - also from B&C. The midrange horn is a "variation" of or slightly modified version of the Eliptrac 400 (the modification, to my knowledge, seems to entail the edge of the mouth of the horn, and how it meets the baffle here) and yes, it’s made of CNC’d, stacked birch plywood.

What’s the details of the bass horn you’re using with the 402 mids horn - does it sport a 15" driver, and how low is it tuned? Any thoughts on the 2" (exit) driver to use?

I am a Crown guy too. Went the consumer route for a while and tried all that "painless one touch" room correction junk and never was satisfied. You just can’t beat the price and clean output of pro amps with consumer gear.

Crown has made some extremely capable amps. Once considered buying a used Crown Studio Reference II - a lovely, very underappreciated amp that I could see go favorably up against a range of much more expensive commercial amps - and within the next month will replace my old Macro-Tech 1200 with a K2 for subs duties. What Crown are you using?

  That DE10 is a super driver and the one I use on the MAHL tweeters I make. The bass horn uses the Klipsch K-43 woofer and is -10DB at 27hz and near full output as low as 31 DB.
  The 2" driver on the 402 is a Klipsch 1132. I am going to experiment with some 2" throat horns soon and thinking of B&C for those to since I am an OEM with them.
  The Crowns are nothing fancy and are xli800's.    A Xilica xp3060 is the brain behind it all.
