Yes Mark!
The more drivers I add the more they rock 😂
I had a measure and a tweak last night.
Wasn't much to get the SPL balanced new loaded left V right.
I didn't have time to do a full phase review but that is next on the agenda.
Unfortunately the UK is out of the closed back 5" drivers I'm using.
Have to wait until August it seems to do the right hand cab.
There are 6 in France at TLHP...
Don't know them as a supplier though.
Hi Speedysteve7
TLHP is OK and have good prices. Remember to create an account and log in, then the prices shown are much better!!!

Fun just began))). It's interesting to see 2-way Synergy with Kappa 12A and Vitavox cross around 700Hz.
That's great to hear.
The first time I tried to buy they said my card was expired, in spite of it being 2025..
Will try again with another card.
They are drivers I used in the evolution of my 5 way system, before the Synergy odyssey.
I do have 3 way though..
I really like the sound of the the drivers for hifi use.
Chose them carefully.
The S2s just kill the BMS 4550 in every department tonally.
Don't play as high but I can live with that, augmenting with the Raal Lazy Ribbons as before.
I don't think I could ever go back to what I'll call disparate horns with large distances between the centres/point sources.
Don't care how good the drivers or horns are.
My room is not large enough for an auditorium sort of config.
Before I listened to excellent drivers on great horns and it was like listening to individual performances (sort of best way to describe a large multi way system).
It had it's appeal, but it was not like listening to a combined performance, each sound and instrument still shines on e Synergy's and sounds amazing but there is the coherency lacking in multi systems I've heard.
The this effect🙂
Right, let's try with TLHP again!
"Before I listened to excellent drivers on great horns and it was like listening to individual performances" - Exactly!
What are opinions on using damping material for the LF in Synergy horns.?
I'm getting great energy down to below 60Hz, no discernable nasties at my hifi volumes?

The LF in your multiple entry horn is bass reflex.
Adding damping material reduces the low frequency output of a bass reflex enclosure.
The usual procedure in a bass reflex cabinet is to put damping material on surfaces that may reflect out-of phase upper band output through the bass reflect ports.
Since the upper pass band of your 12" tops out ~400Hz, damping material won't be effective, or required.

TLHP have done their thing.
My 2 MF drivers are with UPS winging their way to me.
Should be here Friday if UK Customs don't mess with it..

Came across this excellent presentation on Mr Parker's system
I'm Hypex FA253 2 x 250 + 100 Watt FusionAmp curious.
Especially as he seems to run a 7.2..
Meanwhile I'm ploughing on with the extra driver loading for the RH cab for my setup.
All taps and ports done.
Making a new rear can enclosure for this side with the 6 side bolts and 4 front fasteners.
Got new rear cab support rails to fit too.
Really looking forward to hearing the finished pair..

Yikes...
The FA122's that I had were...by far...the worst sounding amplifiers that I've ever tried on my setup. But I think I already mentioned that beforehand.
It seems to occur at very low output levels, well below the first watt of output of the amplifier(s), so those people with inefficient loudspeakers apparently don't hear it.
I did.

Wow, forewarned is forearmed!
Hehe - I'm only curious 🧐 at the moment.
Not going to buy or anything.
I might try to talk to Mr Parker if I get serious .
He seemed to like them a lot on the B&C coaxial / B&C woofered, 3 way Synergy horns in his video..
I finished the 2nd cab full driver compliment project.
New full volume rear cab made and painted.
I really like the Danley method of using long bolts through the rear cab shell through T nuts in the horn.
Really positive fixing and pulls the sides in on the bracing runners nicely.
I wired up. 4 MF drivers to give 8 ohms and the 2 LF giving 4 ohms.
I just need to find a nice way of sealing the hole in the rear of cab where the Vitavox S2 drivers stick through.
Tape works but is not so nice - a neoprene ring, flange etc are on the cards.
Got the cab back in place💪
Running them up now 🎶 😃
2 X LF per side shift some air / punch nicely when called for.
I'll swear the 4 X MFs sound sweeter too? It's okay I'm biased - after all the work I've put in on them😂

I'm no football fan, so listening to music and researching on DIYaudio and occasionally looking at the screen to see what's happened is perfect🙂
A couple of smaller tidy up jobs done.
The first was to find a way to seal around the Vitavox S2 drivers that stick out the back through a ~5" hole.
The foam stuck in and tape around needed something better..
I came up with the idea of a turned birch plywood ring with a recess on the inner surface.
Slightly larger diameter than the S2s themselves.
I cut a ring of springy packing foam that was a tight push fit over the driver and likewise in the recess.
Once bolted up it really made a good airtight seal.
3 screws clamp it in place.
Next up was a pair of screw in adapters to make fitting the BMS 4550 compression drivers back on possible (weddings and garden parties) use.
I was going to turn these but as the BMS are so light I came up with an easier free solution.
Didn't have the plate or bar aluminium to do it from.
I 'cast' polyester resin into an outer adapter ring.
The mould release was works really well - last used when I made a pair of 400Hz Tractrix horns from a mould I also made.
Once released testing in a S2 screw fitting ring.
Whilst this won't be as durable as aluminium it is only for occasional use and does work once the threads were lightly cleaned up with a 45° cutting tool.
Then to fit a spacer and driver flange.
Both from 4mm birch plywood and turn out from 1" to 1.5" over the 20mm thickness.
Close up
Fitted to the driver
Test fitting on the old Le Cléac'h horn
Internal throat view
At some point I will fit these and configure my Behringer DCX to do some or all of the PEQs and delays.
Have everything to copy / take inspiration from the existing DSP set up..
I'll have to make a pair of sealing blanking plates to cover the 5" holes - already have the HF Speakon socket fitted from previous BMS use.
Then to test with 3 PA amps and with ear defenders on😃

Having made the screw on adapters I couldn't resist going back to the BMS 4550 drivers again.
Spent a little time measuring and setting them up.
Easy as the LF and MF did not need to change at all.
I settled on around 900Hz 1st order XO in DSP for them. Not fully settled on that yet though.
Meshed best with the MF like that.
I'm actually quite enjoying them this time - there are some times when they come across as a tiny bit harsher.
Perhaps a little more careful EQ could fix that?
However general listening is pleasant, clear, dynamic and well balanced.
I gave them a very bad rep first time around.
Could have been I was so focused on what the S2s on the Le Cléac'h horns did as a sole performance,
I missed the Synergy cohesive phase performance thing somehow..?
I'll swap back to the S2s again soon and see!
Sometimes I find a change is as good as a rest though, so it could be that playing in too.
I'd like to try something else at some point.
Eminence N314Ts could be alternatives?

Eminence N314T response is not as smooth as the BMS 4550, but is capable of (a LOT) more clean output at 900Hz, especially with a 1st order crossover.
Why do I always prefer a 1st order cap X/O over the DSP BW 6dB/oct one on my HF drivers?
Yes, I know my brain knows it's a cap and therefore tells me to like it more 🤣 But I'll swear the cap has a smoother more natural life-like sound.
