My open baffle dipole with Beyma TPL-150

At higher power levels yes, but not at 1W or less.

There is no such thing as too much overkill!

exactly! you need more woofers

Ok, here's the last update, and it might be the very last thing I do with this system.

The news are:
Hypex Ncore amps - two driving the RD-75 ribbons, and four driving the woofers - and now there's sixteen of them.... a few pics without front grilles on the woofers below.

Your insane 🙂

Very nice system Eric 😎
I am not sure you have enough woofers Do you hear something ? 😀

 

[63781]

A friend of mine said its not enough because he can still see the front wall....

 

[jerome69]

Your friend is not really wrong 😉
We are discussing of the latest update of the latest update 🙂

 

[lolo]

what can I say.. You can compete with Monte Kay now!
I feel like a dwarf with my Orions..

Thumbs up!

 

[63781]

I remember I read about Monte Kay's monster W-baffles with .... how many 15" woofers? 12 per side? Guess I've become just as crazy as him! 🙂

 

[lolo]

something like that.. and still was not happy about the overall THD.. we can only be jealous of you two!

 

[63781]

I have very low THD up to about 100 dB @ 20 Hz, but that is simply not enough SPL for home cinema.

 

[DQ828]

I have been wondering, I hope you didn't take the insane comment literally, if I had enough money to copy your build, I'd do it 🙂

[lolo]

out of curiosity, and for educational matters, how low THD are you getting let's say at 30hz, 95 db?

 

[63781]

Around 1%

 

[lolo]

well done, this is in line with MK results, with less drivers.. how does the organ sound at yours? 🙂

There is no such thing as too much overkill!

If it's worth doing, it's worth overdoing!

 

[Khanate]

Phew! What a story. I've spent quite some hours to read through this tread. Most interesting, inspiring and fun.

Hm, I wonder what those big woofers could do together with my Quad ESL63? 🙂

 

[63781]

Thanks! It was a great process, and a lot of things were learned. 🙂

I think that a single 21" in H-baffle should match the Quad very well!

Have you seen something like this before? 🙂

An externally hosted image should be here but it was not working when we last tested it.

Oh yes, this is the best version if my dipoles when they still had baffles. My good friend Lars is the owner of these. In fact - he was the one that got me into building dipoles in the first place.

They have integrated Class-D amps mounted inside the woofer U-baffle. All that's needed in addition to these active speakers is a multichannel audio interface (like my RME Fireface, you see it lying on the floor there), and a computer to run the XO and EQ filters. Very neat setup indeed, and whow... it sounds great!

HI 🙂

I would like to build these speaker above with these drivers:

http://www.tb-speaker.com/detail/1230_04/w8-1808.htm

Eminence Alpha 15A speaker. The Eminence Alpha 15A is a 15" 8 ohm speaker for all bass applications. Alpha-15A is a 200 watt RMS 15" woofer.


How can I do?

how to build the crossover?


thanks in advance

A very interesting and fun to read thread... just finished reading it whilst watching the Wimbledon finals.

I hope it was more exciting than watching tennis ..... 😉
