I know this might be a long shot but I do see that lots of people on here have used these Beyma TPL-150's. Does anyone have any measurement files to share with ? I'm "thinking" about buying a pair and building a pair of speakers with them. Id be using the Satori WO24P-8 9.5" woofer in a 2 way..

Thanks In Advance.

Thanks sir ! Crossing fingers :)

Just building a test xover to see if it will work, don't want to spend 1200$ on tweeters and they not work good.
Are you going to use two of those woofers in each box?

Because the sensitivity is only 88db, you are going to need to pad the **** out of the TPL to get them down to the level you need, bit of a wasted opportunity IMO... Might want to look into a much more high quality high efficiency woofer. You can cross the TPL as low as 1200 hz pretty comfortably.

Check out some of my builds in my sig to see how they measure...

Id probably use the 4ohm version of that Sb acoustics. It's a 91db driver.. I was only planning on using 1 woofer and 1 tweeter..

The TPL is a 102db/w driver. You will need to pad it down a ton, im guessing that SB Driver is only going to be still about 89db where its actually useful.... But I guess it will also allow you to flatten the response a lot. Its just going to mega raise the impedance at the tweeter.

Here is a zip file with measurements from 2 different boxes... there is a few here, I've built 4 different designs with these tweeters so, they can behave a little differently depending how the chamber is damped, and IMO you really want to look in to taking off the back cover and gibing them their own space to breathe. Anyway, you should be able to play around with these.

Only 91 dB @ 2.83V, which is more than a watt into the 3.3 ohm DC Re. Bandwidth and efficiency are inversely related. 0.3588% no with a 28 hz fs. 90 watt rated power handling.



Spl @ 1W remains at 88 dB. In a ~ 2.5 cubic foot box tuned at 28 hz, your maximum spl based on the Sd and Xmax is about 105 dB at 40 hz, but this is before room gain.



A 0.707 sealed box is -3dB at 51 hz, in comparison the ported box is -3dB at 27 hz.

What are your goals with this speaker build? If you plan to use a subwoofer and cross over higher, I would suggest a higher efficiency woofer, to better match the tweeter.

I'm building a pair of "bookshelf" stand mounted speakers..

Atm, I'm just playing with drivers and ideas.

I simulated the 4ohm sbacoustics into a 1.75cuf box at 34hz..

I did see that vapouraudio made something similar to what im looking to build, but he uses the a&e 10"...

I have a subwoofer i could use. But my ideal goal is to build stereo pair large bookshelf-standmounted speakers..

Don't worry, they're great, one of the very best tweets I've ever owned. Just waiting to finish a couple of other things before I start my large AE/ATC/TPL build.


Another cheaper AMT worth considering is the Dayton AMT Pro4. It got a good write up in Voicecoil mag. No WG for it though, but you'll only need to pad it about 5dB.

PS: some good independent measurements of the Satori here. You need to register to get them all.

I have heard really great things about the beyma ribbon tweeters and it is on my bucket list to create a speaker using them. I don't know the fist thing about properly designing a crossover however...

If someone had a kit with these (diysg), I would love to put a set together. They tend to focus on the most affordable designs as opposed to the highest quality components necessarily.

Talk to Mike Garrett. Every year at Cedia, he tells me that he hasn't heard a demo that exceeds the performance of his system. Mike is running the Beymas along with Acoustic Elegance woofers in a baffle wall.

I have a huge collection of sbacoustics measurements. Thats why I was after the beyma tweeter.. now to see if this two way combo will work and they turn out good :)

Do you have a link to that design?

I think I've seen that on here too. I sold my a&e 15" to ryan.. maybe the 10" would be a good fit.. only thing that really sucks is they are 150$ more than the 9.5" satori's i have fallen in love with.

lol... I was just about to tag Mike. Was literally just talking to him last week about them. He said they're very close to the ALCONS. More so than ALCONS would like to admit.

@A9X-308


Are you guys using just the raw Beyma TPL-150?


http://www.usspeaker.com/beyma tpl150-1.htm


Or the one with the 80Hx30V waveguide, the TPL-150H?


http://www.usspeaker.com/beyma tpl150h-1.htm


If the waveguide version, have you heard a SEOS waveguide and can comment on the differences and similarities?


I'm a big fan of the SEOS waveguide. I love the soundstage it gives. Wonder if a larger version like the SEOS24 would have a throat big enough to fit the Beyman TPL-150.

This one. The WG unbolts.

It depends far too much on the actual WG, the CD and the implementation.

Not a chance in the world. The SEOS throat is round and the Beyma opening is much larger and rectangular.

Thanks for the measurement Files Jav.



This is my first try.
Imo that would sound harsh. You might want to think about a very slight decline from 100hz to 5khz or so rather than pretty big hump in the middle especially at crossover point
