Sanjay Frank I'm so so sorry! I never thought to look. Frankly I was torn between pinning your comment, removing your comment, or the whole video lol. But pinned it is. Thanks again.
in another video there is an 8" full range coral mounted on its back loaded horn which has a deeper bass than this university speaker.. i think its called flat coral
What is eaten would determine the low end response then? So I would say cabbage and Taco Bell could get down pretty low, properly reaching resonance. Aiming the port into a corner would yield ample amplification which could possibly rattle a window or two. You would need a fan too, but not for air cooling, but for removing the resulting envelope of noctious fumes from the room.
@@fanplant I was reading up on the Cobreflex recently and it seems that with the t-30 driver, it has quite a following in the hi-fi market. I am astounded that the Cobreflex has a 250 - 15k hz frequency response. I don't hear over 15k myself, so a Cobreflex teamed up with a horn loaded midbass would be fine for a high efficiency speaker system for me. I was looking into a high quality, hi efficiency sound system for my garage which didn't take much power to run at a decent volume level. Given that I have only one 15 amp circuit in my entire garage, I would be needing something under 50wpc. My backyard is long so that dictates a horn loaded system. The best speaker for the job would be an Altec A7 VOTT speaker, but that is VERY expensive...unless you find one without a top horn...which I did. So that is what was leading me to find a suitable top horn. Naturally I was looking into appropriate VOTT Altec horns, but they are very expensive. It wasn't until I came across an article (after making the post above) that mentioned several fellows at Audio Karma say that they liked the sound of the Cobreflex horn over the original Altec horn. So that had me doing a ?!?! And so my research on the Cobreflex continues. But given to the size of the Cobreflex compared to some horns, it does seem like it is a promising candidate for good sound. BTW, two days ago, I ended up buying a new Cobreflex horn to try out, but it doesn't come with a driver. So now I have to get a T-30 driver. EV does have a T-30 knock off, but it doesn't have the frequency range of the original.
@@jukingeo I think you were confusing speaker efficiency with amplifier needs and many amplifiers draw way less than 15 amps at 120 volts and still make plenty of power. High efficient speakers come from the days of tubes and wattage was expensive. Also when using efficient speakers it's the first clean 5 watts that count.
@@fanplant Nope, I understand speaker efficiency very well. I have been an audio tech for many years. What I was getting at is that 15 amps is for the whole garage, so that is lighting and equipment too. So by right the AVAILABLE power for an amplifier that I could use is about 5 to 6 amps.
@@jukingeo well I do a little trick and play my classics off an ipod. No amp or anything. They aren't incredibly loud of the ipod but they're playing. Also those cheap tripath chip amplifiers work nicely. The Classics have an efficiency similar to the K-horn.
I have a pair of University "Deans". Larger cabinets with cut -off corners. Fabulous sounding. Has "green" C15W woofers, cobra T-30 mids and HF-206 tweeters with N2 Crossovers.
Are the speakers clones as well? Mine are originals from the early 1960's, they were my Dads. Running a 50 wpc class A YBA Integre DT amplifier. Nine- 10 o'clock is comfortable listening volume. My 2nd system is Klipsch Hereseys with a 32 watt Class A tube amp. Nice sounding set-up but the Deans have so much more presence. Very musical.
@@fanplant Oh you did? I had gotten one from a company that said you COULD use their video clips. Initially I thought I was flagged for the sound, but it was for the video. So I got back to them and it turned out that they didn't like the fact that I overdubbed their audio track, which misrepresented their product. I told them to "f" off anyway and I will not buy products from them anymore.
great basshorn - models well with lower Qts 15 inch speakers (back chamber size can be reduced in some cases for a flatter passband) I have a scaled down version loaded with a 10" Eminence. A 12" scaled model would be an excellent midbass horn with B&C 12pe32 or perhaps Kappa12a and keep size pretty small (then add tapped horn/pipe subwoofer for the lower octaves). I assume it sounds more open than say "La Scala".
(Avert your eyes at 30:30.... Plumbers butt!!)

@@fanplant I think we can handle plumbers butt! If Fanplant was twerking, it might be a different story!
Well it was fun. Always wanted a University Dean.
Eminence Kappa 15C will make for improved performance especially at about 400 Hz where it will be up about 3db verses the University woofer.
This is great!
Glad you are enjoying it. Now that I'm watching way more RUclips videos I wish I edited it for brevity.

whats missing on the top end is abundant from the rear port

I see what you did there RG, lol, sorry I took a year to respond
0:55 Wait, wait. Is that a Cobreflex PA Horn I see in there?
That's the standard mid for a Classic with the t30 driver. The other drivers usually found on the Cobreflex horn don't work as well.

Which model are your crossovers? Have you changed out the caps?
I made my own N3 clones. The inductors are pretty lightweight in the university stuff. Not that that matters to much at the wattage we use.

Mine are copies. Factory cabinets are easily identified with less blocking and less screws.
N2 crossovers, yes the caps have been changed. I have a spare set if you are interested.
your rear port is out
Wait!!!! I thought you can't play a song on RUclips because of copyright issues, did this video slip through? Oh well great cabinets.
yeah it got a copyright flag a little while ago, oh well.
