“It’s a heater, but as a byproduct produces some sound as well” 😂 There’s one of those “Janosisms” that immediately made me laugh aloud. Excellent vid. Thank you.
@@hoobsgroove How kind of you to say, Hoobs. What a nice gesture and comment. 🤗 Listen to what Janos says at 3:40 and you’ll realize what I’m talking about….😂 Got it?
@@hoobsgroove Yeah, man. No worries. I figured you honestly didn’t know what I was talking about, and I was obviously just quoting Janos. Ya gotta admit it was kinda funny with that enormous magnet on the back larger than the driver itself….Have a good one, Hoobs. 👍🔊😊🎶
@1:06 the price of $374 for the MAOP is per pair. Yes we wish the MAOP 7 was 2-3 db more efficient but at least it does not have serious anomalies in the response till around 8/10k. Off axis is still controlled (at least 15-20 deg off axis). One way around the very low sensitivity is to use a woofer or 2 below 200Hz to augment the bass and relieve the suspension of the MAOP. One driver you missed is the Tangband W4 1879. It’s price has recently jumped up (@ Parts Express) but it was under $100 per pair not long ago.
In order to be most authentical I bought the FE 103 NV, wich is the direct successor of Hiraga´s FE 103 Σ. Unfortunately it has a big hump-valley at 2K. It has the similar funny roundish center cap like the old version. Now I would consider the NV 108 EΣ, and I think it is possible to recess it into the baffle, I would machine a ring to make it flush. Pity the Markaudio have so bad efficiency, the "Alpair 6P A" with paper cone has a nice characteristic, as well as the "Alpair 12P" with 19cm cone.
Hi Jürgen, you made a good choice, there's an easy fix to the valley at 2kHz. I will talk about the 103NV and the fix ; ). (Hint: we are going to horn-load it! - - in a super simple way, no harder than regular build. ; )
108ez shows a good FR curves similarity from different angles. Like a point source. That must sound comfortable (when you tame 2-5kHz region). Of course modern Fostexes are far from past years models.
Hello Janos, Thank you so much for giving your insights on these drivers, and the LePetit! Although I don't comment much anymore (I watch on my TV instead of the phone,) I watch ALL of your awesome videos. I have used the FE126 for about 8 years, and am always delighted to listen to music through it. I noticed the Fostex 108-SS HP on the Madisound website, and was wondering if you had time to share your thoughts on that driver. I have tried the 108 Sigma (and some other 4-5" FR drivers) and thought that it was just "OK" compared to the FE126. Would this, or any of the Markaudio drivers like the MAOP or Alpair 7 be an upgrade for me? They all seem to be of lower efficiency, but perhaps more balanced. I am still using my DC 45 amp, and can use 2A3s in it now as well. Best Regards, Cory
I was just thinking about expanding on this..... there's a duality to hearing.... conscious side and subconscious. Consciously we (not-so-young adult male population) hear only maybe 40Hz-13kHz or so at medium-loud volume, yet our subconsicous still registers the whole extended range... also, the subconscious 1Hz - 150kHz range can shrink down to 1Hz-16kHz or less, or just have huge gaps in it....
@@realworldaudio Thanks! I will go for that then👍Just check; 40cm deep is at the bottom? And what height for the center of woofer(distance from bottom to woofer center)? Great videos, love it🤩🙌🙌🙌, Toby, Sweden
Hi, I have been watching all your videos (Great!) since we had this conversation and I have some some more Q's, I may not have understood all of your suggestions... But please give it a thought, I will be very thankful! 1. In building a voight pipe or folded Voight pipe; should all sides of the cabinet resonate or is the fron/back more rigid and sides resonating? Or the orher way; sides rigid and front/back resonating? 2. In a folded Voight pipe, as I got plans for from Cube Audio ( make the loudspeaker not so high...) the interior "pipe wall", should that also be real wood / plywood, or rigid(mdf)? 3. The opening, at the front bottom of the Voight Pipe; you suggested to me total VP height 210cm, width 28cm and depth 40cm, woofer at 95 cm. which is the optimal opening height (?) and what effect would a smaller/lower opening height have, and a bigger/higher opening height have? Best regards, Toby from Sweden

Found the same thing, the older Fostexes were better than most today.
@@ShutterNChill That's sad. These could be better materials: magnets, steel, paper, glue..
U missed jordan speakers.v v good
What happens with the FOSTEX FE108SS-HP is this a good one for the le petit ? Many thanks and regards.

4 inch in voight pipe?
Why is it that you sometimes talk about our ability to hear up to 150kHz and sometimes you presume that some people can just hear up to say 10kHz 😊
I was just thinking about expanding on this..... there's a duality to hearing.... conscious side and subconscious. Consciously we (not-so-young adult male population) hear only maybe 40Hz-13kHz or so at medium-loud volume, yet our subconsicous still registers the whole extended range... also, the subconscious 1Hz - 150kHz range can shrink down to 1Hz-16kHz or less, or just have huge gaps in it....
What about the 70's Coral Flat 10, is it a good choice for a Voight pipe? Dimensions for Voight Pipe Coral Fla 10? Come on, gimmi some mate 🤗
I suspect it would work well in a Voigt pipe, a big one ; ). 210cm tall, 28cm wide, about 40cm deep;
@@realworldaudio Thanks! I will go for that then👍Just check; 40cm deep is at the bottom? And what height for the center of woofer(distance from bottom to woofer center)? Great videos, love it🤩🙌🙌🙌, Toby, Sweden
@@torbjornsjoberg6516 Yes, at the bottom. Driver height: approx 95cm from the bottom. ; ).
@@realworldaudio Great! Big thanks, and will send pictures/comments from the building process, Best regards, Toby
