Can I ask the thoughts on the pros vs cons on the match of the td10m vs td12m in regards to the best match to the tpl 200h
2way vs 3 way
Sealed vs ported
Crossover points
Beaming
Etc
Thanks

Vapor Audio had a 2-way with TPL-150H and TD10M, crossed around 1.2kHz. Can't remember the model name.
TD12M might make sense for a 2-way. If going 3-way it might be better to use TD8M or 10M plus a AE designed for the low end (M range isn't aimed at that I believe). It's probably best to ask John at AE.

Thanks for the reply
I have td15h+ in small sealed boxes as stereo subs
So I was going to either turn them into a 3way or replace the 2 way thats currently above them
The reason for a 2 way is I can over lap the 100hz area to help with room modes
There’s not much data on td8m ? And maybe there’s resonances ?
TD10M would work better as a 2way it seems
I’ve seen your name pop up in some threads I’ve been reading
Which drivers did you end up with ?

So I guess it comes down to two kinda systems
Tpl200h - td8m( ported or sealed ) - td15h+ 3 way
Or
Tpl200h - td10m 2 way (ported or sealed ) + td15h+ subs
The 2 way + subs will let me crossover say at 60-80hz making easier integration and smoothing of the 100hz area via multiple bass sources
But I guess the 8” is better in the crossover frequency to the tpl200h
And a better match ?
I also need to revisit removing the back of tpl200h and having it in its own chamber
I read this then needs eq?
Tpl200h - td8m( ported or sealed ) - td15h+ 3 way
Or
Tpl200h - td10m 2 way (ported or sealed ) + td15h+ subs

Hello.
Indeed I was looking into TD8M to cross to a TPL-150H targetting a xo point in the 1.8 to 2kHz mostly from reading post about the TPL having a resonance around 1.7-1.8kHz.
I ended un buying B&C 8PE21 because thwy were available here (vs importing AE), had great reviews and high sensitivity. TD8M was a bit less sensitive for my needs - at the time looking at a 2A3 amp to drive them.
The 8PE21 have worked very well. However my design evolved into an open baffle. I'm running the TPL-150H open in the back - much better than the plastic back from Beyma. I cross them at 1.2kHz now and like it better than crossing higher. Mine is an active system so this is easy. TPLs driven by a 45-type SET and 8PE21 driven by class A/B tubes.
At 1.2kHz I could probably use a 10" and be good. In fact I might do that, but working on other part of the system now.
Your plan with 15" AE subs looks great. Is your system active/passive?

Hi system is active im new to diy but active would be my choice anyway
So opening the back of the Beyma so there dipole gets rid of the resonances at 1.7-1.8k? And aloes you to cross lower ?
Is that the same as running open back in their own chamber ? They can then be eq d for peaks ?

I never verified if I had resonances, so can only talk about how they sound. Crossing at 1.2kHz to the 8PE21 on open baffle sounded better than crossing higher. Maybe because the TPL sounds better than the 8" in that region.
Opening the back into a large chamber is similar to OB only in the sense the box wall is far away and any reflections should be absorbed within the box on not reflect into the membrane. Of course open baffle allows the back wave to hit the room wall behind the speakers. Some people like that effect.
I would ask John for his view on your alternatives. It takes time to get an answer but he does answer.

Sorry for the delay.
Yes, have heard from people who heard the TD8M. Examples:
https://www.diyaudio.com/community/threads/beyma-tpl-150.390081/page-2 post #21
Another poster privately messaged me: "
And yes in general AE gets pretty much universal praise on forums, and yet there is little measurements shown etc.
I was very set on buying a combo of TD15 and TD 6/8 for a while due to all the praise.
But digging further into the subject made me think twice.
The TD6 and 8 first version was pulled from the market to be reintroduced again with a different basket and I guess a few other changes."
Other comments over time too.
Some measurements here and there.
Seems like a good driver to me. Best one to pair with TPL from 250 to about 1.2kHz? Dunno, but good candidate. Maybe TD10M is also a top candidate.
For use with low-power SET I also had my eye on B&C 10NDA610 but havent heard it.

Thanks mate appreciate the input,
Looking around and reading the whole of the “which mid for tpl “ thread 8” and 2khz and above seems to be the best for the tpl150/200
I’m not sure if the 200 differs from the 150 in regards to the 2khz and above crossover and if the chamber mod lets you crossover lower?
Td10m is probably the better choice for more of the two way I’m after due to bigger xmax and size
I’ve seen a lot of people cross them over around 1-1.2khz
Sealed vs ported is also something else I need to decide
The b&c you are using seems to get a lot of praise I can see how you ended up with it
Are you happy with it ?
I could try them to make a 3 way there cheap enough unlike the td8m
Hello!
Am I happy? I am.
Am I thinking of trying new things? Also true. Not because it doesn't sound good as-is, but wondering if it could be improved. A number of aspects in my system have higher priority than improving the midrange driver, though.
One important conclusion for me is that I don't need to cross around 1.8 to 2kHz as I once thought. At least while I use the waveguide in the TPL. I'm happy around 1.3kHz as today, which broadens the options for midranges. Some folks argue for larger midranges.
One option could be to try:
a) TD10M as midrange xo around 1.5kHz from TPL and with a 12" woofer
vs
b) TPL xo higher to 8pe21 and TD10M as woofer.
TPL both 150 and 200, especially with the waveguide, make more sense if xo lower, in my view. In my case I really like the combination of TPL plus SET amp and want to broaden the range I use it in as much as possible.
Having said that, at some point I'm likely to try TPL without the waveguide xo around 2kHz to a 5" midrange I have and see if I prefer that combination to what I now have. 🙂

Yes nice ideas!
Do you think removing the back is what allows you to crossover lower without the problems others used to hear ?
Not being able to cross the tpl lower became a frustrating problem as it made it useless with bigger drivers which was the whole point in the first place for me
Is the 1.5khz crossover to a td10m suggested because that’s a good polar match between the drivers ?
Any idea on how the new Purify PTT8 compares to the AE TDM offerings?
In Europe, due to shipping and taxes, dual AE TD10/12 is almost as expensive as dual Purify PTT8.
The main problem i see with the PTT8 is the sensibility, which is only 89.3 db against the 93.6 (TD10M) and 96.5 (TD12M).

I've used the 10M and TPL150H with a similar xover freq and 15S below. Thinking about a 15X/10M/TPL/10M/15X vertical array, active of course.
I wouldn't use the 10M as a woofer.
That looks a great driver and maybe a better Option for me
A 2 way with something like the sb acoustics TW29BNWG would maybe make a great combo
I may also look into this
I can only confirm that the combination of TD8M with TPL200H in my OB system sounds very nice. Until now I used the 250/2500 crossover separation with Audiolense. From these discussions here I decided last night to try 250/1300 Htz. I have to agree, it sounds great and I will stay that way. Thanks for the suggestion, LewinskiH01!

I did this on a pair of TPL-150. Did not notice any change in frequency response, but the decay got a lot cleaner, and THD greatly reduced. Both OB and large rear chamber will work.
