Altec? Or…I may be losing my mind.

So I have a much smaller listening room than before. That however has not prevented me from squeezing ridiculously large speakers in here. But the recent Japanese SET question has me wondering. Is their a speaker that is not the size of a refrigerator that can give you that “Sound” at a smaller scale? I saw there was an Onken petit for example. Does anyone here have any recommendations? Criteria are speakers able to live in a small room. Not in corners and into the room. Full range and NOT OB. Bonus points for looking like an Altec or something @Redboy would like if he ever manages to finish anything. Can it be done?
If you ever find yourself in the northern Philly metro area, you're welcome to my DIY/SET/Altec man cave.

Nothing bigger than 4 cf and 8 Wpc tops! :)
 
I use GPA 414s in petite Onken cabinets and a variety of interchangeable horns up top. They are still pretty large.
My first exposure to Altec 414As were in Herb Reichert's Petite Onkens.

Is there a reason nobody mentions the 602? I’m about the furthest from an Altec aficionado but I liked a pair of those. I like the 604. Didn’t really connect with the boleros I had.

Through the years, the few 602s I've seen had bad tweeters. AFAIK, the woofer section of the 602 = Altec 15" 803A + the fragile 3000A tweeter.

I have a pair of Altec Maderas and the Heppner horn can't reproduce top end harmonic overtones as well as the Altec 3000. But as I've said in previous posts, I'm also a fan of the 10" 406Z and 406-8Y drivers.👍

I might be thinking of something else. In my mind it was a 12” coaxial in a “sanely” (apartment life) sized box. I’ve always regretted not grabbing whatever they were. Not the last word in detail but very engaging. They were what I was hoping my Boleros would have been.

Maybe one of the Stonehenge models?

If it's a 12", it may have been an Altec 601 variant, 414ish woofer + 3000 horn tweeter in a 3.5 cf bass reflex cabinet.
 
Here's my small room with its low cathedral type ceiling. The sound absorbing panels on the back wall really transformed the room. I added the two on the front wall only because I had them. The side walls were not really an issue as the left side is open and the right side has a window that naturally disturbs reflections. My approach was not scientific and probably not optimized but, it sure did work for me. A few hundred dollars spent on the panels had a greater positive impact than any amp/tube/turntable/DAC/etc. "upgrade" i have made.

Our lounge where my stereo is has a higher walled cathedral ceiling. For years it was set up so the speakers fired across the "arches". It was a reflection nightmare. And the wife would have nothing of room treatment panels.

Rotating the system to fire lengthwise with the arches transformed the room.

Could you tell me a little about the Executone cabinets you have? Back in the mid 70's I worked for an Executone distributor and installed paging, nurse call, intercom and telephone systems.

I have a small room. I run two Se amps, a Golden Tube SE 40 (3 6L6s per channel) I restored/upgraded and an Elekit TU-8900 kit I built (2A3s or 300Bs). I ran Klipsch Heresy 3s on stands aimed straight ahead, with 2 subs. It sounded good, but my new Forte 4s are much better. They are also smaller than Altecs.

I had a pair of SE40s for over 10 years
What is your thoughts on yours sound wise?
They were my first tube amps.
 
I think they sound wonderful. My TU-8900 CAN sound noticably better, IF I'm running "the good tubes" (read expensive), like real WE300Bs or NOS '40s RCA 2A3s. With inexpensive Sovtek, EH, JJ or Chinese tubes in the Elekit and the JJs or Sovteks I run in the SE40s, it's usually a trade-off depending on what I'm playing.

I used them bridged to mono driving a pair of Matin Logan Arius.
Very much enjoyed them.
 
I have no direct experience with them, but I think Econowave type speakers might satisfy your desires. The formula is scalable to room size.
 
If I wasn't "crazy" I would have just stuck with the set of Valencias I had, where I took the compression driver off of the horn and placed it on top of the cabinet with a SEOS waveguide. That sound was amazing and simple.

Then a set of 1003b horns came along.......and the madness ensued.
 
I think what I really want is something that has the look of the eXclusive 2402 but the efficiency of the Altec models favored by the cult…I mean aficionados….yeah….
 
the pioneer2402 looks to be approx 3cu ft? . If that is the look you want. Build a set similar except maybe a touch bigger and you should be fine..my 414's are in similar size and once I got the right amp on the best sounding OT tap, the bass is fantastic - matching the speaker to the mating amp was the biggest revelation for my diy altecs. Also use a smallish room and found no benefit to horns, so the compression drivers just use the one inch throat itself as the horn. Sound much more natural to me. The horn is for projecting into larger rooms no? and most have strident or particular FRresponse issues that are not there if you dont use one....but that pioneer features a gigantic horn, so I guess that is the look you like...try it..

Looks play a large role in this spit balling exercise bud.
 
that's why you should build 'em, once you're done spitballin'. they'll look like you want and likely sound fine, with exception to the horn artifacts

diy'ing speaker cabs is a dark art in any case, so worrying too much about size is not worth the effort. Add to that speaker variation and it's even less critical..have 4 414's (that even came from the same cabs), and each sound significantly different from one another. and it's not unique to the 414. All drivers whether its woofers or headphone drivers. vary widely due to unavoidable production and use/time variation. you could take plans from someone who painstakingly analyzed and build petetie onkens for a set of 414's and that will not mean your set of 414/416 etc will provide same results in that cab. Add to that the subjective nature of designing a cab (even analysing responses and graphs is subjective in large measure). Add to that room difference and one begins to see the futility...so I'd pick a look one likes, get close to size. build it, and play with ports and amp matching. done. enjoy
