So far I’ve never heard a 211 amp at home though they are very much on my radar and I have enjoyed the ones I’ve heard at shows etc. I’d love to hear some with my Ocellias, sadly a 211 amp with minimal compromises is quite an expensive undertaking! Hopefully I’ll get a chance to try some here soon.

Two years ago I had considered attending this Guangzhou audio show to listen to Line Magnetic speakers.
Those speakers are on sale for 2 days with discount of 5%.

Frequency range : 23Hz à 20KHz
Input sensitivity: 105dB
Load impedance for HP to connect: 8?
Screw terminals compatible with banana plugs
Treble driver: LM302
Bass driver: BA-18
Woofer diameter: 46 cm
3-way passive filter: TA-7376

Horn: 22A
I almost pulled the trigger for this one without audition two years ago.
At that time total cost to me including shipping and tax was 16k$, but now the cost is 19k$ even with 5% discount.
But now I get the feeling that I may be happy with the above one if I got one.
After I get Altec A7, it is meaningless to get the above one.
LM-7396 speaker is 100% duplicated king of the speakers of American WE Company: 4181,555,597.
LM-7306 always use for cinema is one of the most classical barrier plate speaker systems in American Voice
Age.
18 inches low-frequency of 7396 using 4 ways vacuum tube magnetic power to supply power with high
sensitivity and strong pull.
Reality sense and scene sense is excellent, and the sound quality of all audio parts also good.
LM-7396 barrier plate audio system can make you listen complete sound of WE Company.
Parameters
High frequency: Duplication of 597
Medium frequency: 22A horn speaker + duplication of 555 or 555x2
Low frequency: Duplication of TA-4181
Frequency divider: Duplication of TA-7395
Power-supply: 3 ways power PR-22
Dimension (WxHxD)?1725mmx2070mmx1063mm
If I go for one now, then above replica with field coiil will be possibility, but the total cost will be 60K$ even with 5% discount.
If it really does fully 'replicate' the WE sound then it could be a bargain of sorts

Replica of Altec is also on sale for 5% discount.
It appears to sound decent.
Thanks David, I had a quick look at the SJS Arcadia amps… lovely stuff. Their build looks great. The SE 300B looks very interesting also.
THe LM3 with teh 22A replica sounds very good. I have heard it twice now (once at a show and once at a dealer) and while not tonally that neutral it is very engaging and dynamic.

It would have been nice to have a chance to listen to it.
Just one question.
Do you believe in 105 db/w efficiency with LM3 speakers from your listeinging experience?

Got it! I too am drawn to this approach- am always curious about real world examples.

Best for open baffle are AE 15" dipole high qts and low fs
I use a modified eminence

Dipole15 woofers are designed for open baffle bass applications. Featuring the Full Copper Faraday Sleeve (FCFS) for incredibly accurate reproduction.

Yes even when quite loud the power needles on the LM219ia barely flickered...quite effortless.
Wow!
I should have pulled the trigger two years ago.
It may be too late.
Wait a minute!
Can it be driven by 300b SET?
If it can be driven by 300b SET, I may go for it after my Silbatone 300b SET get repaired Feb next year.
So far I got the impression that 300b SET may not have enough power to play Altec A7 (97db/w) loud in my high ceiling listening room.

those for me are NO baffle speakers, I have never heard one of those sound anywhere near as authentic as what I've heard with open /infinite baffles. IMO that has to do with Xmax required to create dynamics and the distortion that comes with higher SPLs.
Adding to crossovers does not help either.

if you have the space for it, that sounds very good ,in normal living spaces this is impossible. your tesla woofer have a qts 0.4 you lost 10dB sound pressure at resonance frequency 35-38hz full pressure. I would like to see a measurement when you are done. I wish you a lot of fun listen music
NOt sure where you found a Qts of 0.4, this is what I found
In my current design the horn lifts ~3 dB up to 500Hz, there for sure is a drop below full spl from ~50Hz down but the definition is there also due using three woofers with plenty surface area.

yeah there are enough different Tesla's all with very similar numbers....the 942 does not sound anywhere near as good as 835 infinite baffle or used otherwise.
