Hi there!
Inspired by the Monitor Audio Monitor 3 enclosure recycling project
i am thinking about the recycling of a very old pair of Monitor Audio Monitor One speakers
I have some very different chassis already available for the exchange of the old chassis
I have a mini DSP 2 X 4 HD box and still struggling with the power amps
best thing would be to flip to something like Hypex FA122 but for the first development approach i will probably use the power amp section of an old Yamaha AV receiver
next post with some options about the new chassis
I have the CLIO pocket measurement system and unfortunately a big lack of ability to use Vituix CAD but a dozen of years of experience with Visaton Boxsim

Hello, All!
Just joined today as I found a very useful guide here on using Hypex Filter Design, thanks to DannerD3H.
I have always been a music and audio fan and find acoustics and speakers particularly fascinating. I always wanted to design and build my own speakers but never got to it, mainly due to lack of space to use for woodworking (I live in a small flat). But still decided to go for it. I will work around the difficulties somehow. If there is a will, there is a way.
I have reasonable understanding of audio, electronics and design process and ok to use my hands, but I have almost...

Using the amp section of the Yamaha is a good idea,
Why not?
I’ve got FA 122’s in a pair of 2way bookshelf. Hypex is good but certainly not the only way to step in.
I don’t recall the software for minidsp 🤔

I don't know how similar Clio 12 and Clio Pocket are, but maybe this will be helpful, even if it is for Clio 12:
"Measurements with CLIO 12 for crossover simulation with VituixCAD"
I also started with BoxSim, with version 1.x in my case. But after I got to know VituixCAD, I switched to it completely. 😎

These Monitor 1s must be the baby brothers of my Monitor 3s! Mine were bought early 2001 and were from an earlier year, so at least 25 yo. Yours look very similar but not identical. Possibly a bit better drivers?Hi there!

Fitting a Hypex FA module in an existing box needs checking of the dimensions. Depth can be accommodated outside the back of the existing box, but H and W need to fit within the front profile.
Using a multichannel receiver is a clever and cost efficient way, but as any external box will add cabling and use up lots of space, but will also make the box work much simpler.

I'm feeling like someone has added those extra screws. Perhaps the normal ones don't grip well anymore, or there was a rattle/leak from driver frame there?
Just to add - when I added the Hypex module to my Monitor 3s (using the same drivers), I was absolutely amazed how much the performance improved. Especially in the low end.
For what it's worth -- I once stacked a 5" fullrange as second midwoofer on top of Monitor 2.5 (slightly larger sibling of the 1 shown), and had to report my "nirvana" experience on audiogon forum. (Straight-through bi-amped 300B SE -> Monitor 2.5; Bel Canto S300i ICEpower -> Fostex F120A.)
Eventually I did another "stack" shown here:
Eventually I did another "stack" shown here:
Two stacked fullrange 5" (really 4.5) run XO-less in series: upper 4ohm Michael Audio "drum paper" in 6L labyrinth (slot-loaded); lower 8ohm Correct P-610 variant in 17L up-firing tower (was subwoofer) with bottom port. BR/BR cabs punchier; folded (using divider boards) tapered-TL/ML-TQWT cabs more perfect. I don't know what "transcient-perfect" means exactly, but to my ears this LX-like pairing deserves that adjective. Speed and clarity of ESL; linear dynamic articulation of Axiom80 (alas from memory); an order more musical detail than beryllium headphones; natural realism. Reproduces...

Hi there,
many thanks for the good feedback so far!
I try to make my points in quick answers
A ) cabling
i have seen very effective cabling options with speakon connectors, there are options for 2 pole 4 pole and 8 pole
B ) choice for new chassis
i have spent some money in advance in the Corona years before the chassis prices exploded at least here in Europe after the war started by the Russians
i have 8 Visaton B80 chassis in the drawer and want to use 2 of them, first idea is to add a small SW chassis like the Visaton KT100V or something similar even cheaper that fits in the small Monitor One cabinet - tried first the W130X - does not fit in the cabinet
C ) Visaton simulation screenshots for B )
next post before this post times out anyway

Visaton Boxsim screenshots and project file for KT100V + B80






most notably the max SPL in the bass will suffice only for very low listening levels in the low frequency area, this is more something for a near field monitor on the desktop
the very first trial could be to keep the Seas bass mid range chassis and flip the tweeter probably very degraded in performance after 30 years with the 3.5 inch full range chassis
so far - so good, Stefano

CLIO pocket impedance measurements old chassis


tweeter impedance coincidence red green isn't that good anymore
most likely ferrofluid degradation
first replacement approach with 2 Visaton B80 FR chassis and two 4 inch woofer replaced with other woofer with better mid range performance in an active near field monitor some years ago - for the low crossover to the FR and active EQ they should be good enough

my problem is that i am a terrible carpenter, but it should be possible even for me to build a new baffle for the old cabinet

So, what were the two screws in the middle doing?
in addition to the last post i remember now that some years ago i made some tests with the change of the old Seas woofer with the other one coming from the Adam ARTist 3 active monitor in the 2nd picture for the first replacement approach
in the meantime i am not sure if my post make any sense at all since i doubt that the cabinet build quality and the degradation of the quality with the testing in the past years is worth to keep it
the monitor 3 of the other post is much worth to keep it with the genuine wood veneer in excellent conditions
