with small drivers with output limits placing any vent be it reflex or back loaded horn mouth, placing it on the rear side of the cabinet will maximize the effect of boundary reinforcement for the deepest tones offering the greatest gain unless you intend to wall mount.

Just a suggestion that mot having the curved reflectors at the bends enables more of the high frequencies to exit the mouth of the horn which is something you don't want to have happen as it confuses the image creating multiple sources. Placing the mouth of the horn on the back side of the cabinet will assist in you hearing less high frequencies exiting the mouth or at least delay them long enough for your brain to recognize them as reflections which is a better compromise. Nice job thanks for posting, going to look for your next post now.

Great stuff my Hi Fi journey started in Waverton in 1976 with Kef Calinda speakers , every one else had a nice car and I had great sound !

good sound and great woodwork. Tell me the dimensions of the cabinet. Bought a couple of these speakers. can't wait to build boxes for them.

In the 70s I ran a HiFi shop in the UK. We had the (then) complete range of KEF speakers. An interesting thing was that in 4 years we only sold 2 pairs of Concerto. Other models like the Cadenza, Choral and later the 104 sold very well indeed. Personally, I never liked the Concerto, I found it muffled and lacking in detail, compared with the other models in the range. Your version, looked like a very early one. I just wondered, if you could have had a comparative dem of all the KEFs would your decision be the same?

Very nice ! 🤔

Long time no see , I have not seen that model of KEF , of course I live in the u.s. , what years was they manufactured ?

All most beautiful!

Would you buy them with 5 way binding posts? I can easily make new rear panels.

Dropped the ball by not putting 5 way binding posts in them

What's most sweet Tube-sounding chip in your opinion? And, generally, by slightly overpowering chip amps, what's the sound signature result?

Sounds good!

А можно же сделать ещё меньший динамик, и ещё более огроный ящик?) ну, чтобы смотрелось максимально нелепо и смешно?

Sweet build! I just finished FHL’s and am starting FHxl’s with Mark Audio Mh-110’s. I can’t believe how good these sound!

I see that the port of your speaker is smaller than the end of the pipe. This causes the wave to compress as it reaches the end of the box, which sends an interfering wave back up the pipe. A true Voigt pipe expands continuously to the end. You might consider opening the port completely.

Is this truly a Voigt pipe? It looks to me like a horn. Also, the port is smaller than the end of the horn, so the wave is compressed as it exits the box, which sends an interfering wave in the opposite direction. My first suggestion (because it is easy to do) would be to open up the port.

Greetings Peter, once again congratulations on a well-made enclosure for these excellent drivers. Have you perhaps come across their technical characteristics somewhere? I got a couple and I want to do a sealed box type as part of a 2.1 system, where they would be relieved of the deepest spectrum. Any suggestions are welcome. Thanks in advance and keep up the good work.

👍♥️🫂

This is about as exciting as watching wax melt. ☺️

I wish i could miter that well! They look great. I use bees wax everyday to build pool tables. Its a versatile material.

I'd agree the Alsyvox/Aries Cerat room was one of the best sounding rooms, alongside Nirvana's room. Though i'm surprised Hi End Audio's room featuring the Audio Solutions Figaro M2 speakers and Soulnote A-3 integrated didn't make your list. I rated that room higher than some of the other rooms you featured.

What type?

I got mine for $20 at a thrift store also! Sounds really good definitely a score!

Sold and off to WA.🇦🇺☮️

It makes no sense. With such size it’s better to use headphones. Otherwise just put these drivers into a proper, supposed case: a soundbar.

I thought the Duntech room was going to have Sovereign's? I saw they were advertised. That's false advertising.

The Audio GD are GanFet class D amps.

Holy crap all those macs are complete overkill haha

The Alsyvox/Aries Cerat room was the stand out. Crazy good

Alsyvox are not electrostatic speakers, they are ribbon speakers. Similar but not as hard to drive.

I love the Duntech speakers.

How do you compare this driver to the wood cone used earlier?

Interesting. Must try this FR10HM. Any thoughts on the dip at 500Hz?

Splendid works! SB Accoustics is made in my country so i can easily get it. Could you please share the diagram for this enclosure? Really appreciate it if u could help for my first project. Thanks in advance.

Good work mate. I've started downloading music and buying physical music apposed to streaming. I have a niggle that Hollywood is going down the toilet and the music industry is following behind. Streaming services are on struggle street. I bought a DAP to be my music streamer as it is quite versatile. I plug it into my receiver via 3.5 to RCA connector. The sound is clear as it has an onboard DAC and clean amplifiers. I've copied all my CD's and albums to SD card and backed up on a hard drive. If I want to bluetooth music to my system the DAP receives bluetooth quite easily (For whatever music streaming service). When I'm out and about I use my DAP with IEM's or 3.5 to 3.5 it to the car stereo.

Beautiful work.

Speakers sound great in those cabinets. Good work.

Got to hear a single driver full range horn loaded speaker today at a hifi show. WOW. Incredible bass for a 6-8" driver, with lots of detail. They were using a super tweeter of some sort as well.

Another option would be to turn the rear panel into a passive ABR (Auxiliary Bass Radiator). Can't remember what UK small bookshelf speakers employed this in the '70s.

1) OB? 2) CB? 3) VB? The differences were pretty obvious. As to which was which?...

Beautiful work, superb sound.

man idk who the fuck you are but do your thing bro

Nice job.

Hello mate , great build and beautiful woodworking, thanks for the Nick Cave , a real banger . Have you ever used any of the Mark Audio fullrange drivers ?
