Hi,
planning some serious OB similar to what studiotech did(see post #1252 in the OB gallery). Loving my BG Neo10, recently added Mundorf AMT 25D6.1-R. The RAAL dipol ribbon was impossible to get and quite $$$$$.
So MT and HT are set, baffe will be a copy of the above.
But which 15" bass driver to add? There will be 2x Rythmik Audio sealed 15", so I only need to reach down to around 60HZ. Upper crossover point would be around 250-300Hz, so MMS shouldnt be too high. Think I prefer the lower QTS drivers to real OB specialists.
Crossover is a DEQX HDP-5.
Acoustic Elegance is far too expensive here in Europe. I was thinking Beyma 15P80ND, but never saw them in an OB config.
Any recommendations based on experience or speculation?
Cost no object (well, almost).
Any fancy BMS, B&C, 18sound ....?
thx
WK

If cost is no object than: BD-Design - Quasar MkII
If cost is an issue then Beyma 15LW30, Beyma 15P80Fe/N or Eminence Deltalite II 2515. Every one of these will work like well down to 60Hz.

Maybe these will do as AE isn't an option etc
15″ Audiophile Grade Open Baffle Woofers – PureAudioProject
Edit: I didn't read the opening post properly, these probably won't do re Qts

I listened it in Oris Swing.
You asked for cost no object ob woofer - BD 15 is just that. It is based on previous version of Beyma 15LW30 that had Mms of 83gr (newer version is about 99gr and not as good imo).
a waste of money, IMO
That will do an excellent job:
FaitalPRO | LF Loudspeakers | 15FH500
In fact for even less money, that one is also an excellent choice if you really start @ 60hz
FaitalPRO | LF Loudspeakers | 15PR400
Understood, but wouldnt that mean a high er Qts driver? In my Simulation max Spl was Quite low With Any 15" driver....
I think 60hz is a reasonable target. If he already have 15's in sealed box with EQ possibilities, i would't bother going any lower with OB midbass...
i'd aim higher lowpass xover, though!
Very high Sd/Mms ratio (north of 12cm² per gram) is interesting and useful only if you plan to use it in the higher frequencies.
There is no need to sacrifice Xmax and Fs if you plan to cross at 300hz or so. Especially not with a DEQX!
Why not buy something that is able to multitask ? I'm not talking about BD15 now but in general. There are no such thing as sacrifice of Xmax or Fs - there is just suitable and unsuitable usage. If it measures and sounds good, then it is justified.
As for BD15 - i'd rather go for Beyma. It is much more sensible choice. But when someone asks for "almost cost no object" for whatever reason, i deliver
I suggested three more woofers though.

Hi Jon, thanks for your educated guess, I will give it a try once my test baffle with the choosen 15" Bass is in place. I figured already that the NEO10 has some issues in the 200-300 range, I might just try 400 and 500 xo..
Still hesitating to follow your FaitalPro recommendation. Perhaps its psycholgy, they are too cheap or so
. On the other side my experience bying based on the highest price gave me no good experience.What I like with the Beyma 15P80nd is the cone mix of paper and carbon.
Perhaps I try them both, should be easy to sell after a short test.
cheers

If you have any hesitation regarding Faital Pro, then go for the 15FH500. You just can't go wrong, really. Well designed, well built, great specs.

That one, right?
According to what i see (never tested that one but i sure can imagine) the sweet spot of that one, the ''filet mignon'', is between 700hz and 10khz, which basically means that's a midrange...
I'm just throwing suggestion here, based on my experience (especially with the great tool the DEQX is), what i'd personnaly do is:
12PR300
FaitalPRO | LF Loudspeakers | 12PR300
+
RAAL 140-15D (which would completely replace the BG neo 10)
Crossover points of 70hz & 2khz @ 300db/oct.
I wouldnt use that combination without a DEQX (300db/octave) though... But with it, you'd be amazed how such an unusual recipe could work well.

You have to put money where it counts. You're well started with the DEQX and sealed boxes with 15's for sub-bass. Now, good tweeters that can be crossed low are expensive. There is no way to avoid that, unfortunately.
Save money on the midrange and put it on the tweeter, that is a better investment, IMO.
And then, if you're ready to go to the next level, ask DEQX for the digital output option and run a multi-way DAC from Forssell.

Then you'll probably have among the finest equipement money can buy.
