Default Good small woofer match for Dynaudio D260?

I'm looking to build a small (ish) pair of book shelf speakers, and I already have a pair of Dynaudio D-260 tweeter on hand. I'd love to find a woofer in the 5-7" range that I could use in a small box, and would compliment the Dynaudio's nicely. Something proven would work very nicely also. I don't have as much time as I once did to get into the minutia of speaker building. The Dynaudio 15W75 or one of the 17W75's is an obvious answer, but I wonder what 2 decades of advancement in woofer design would give me.

Anyone have any recommendations? I pretty open to any suggestions.

You could consider this Morel CAW 538 5" Cast Frame Woofer 297-082 I have the previous mw144's. These should be easier to work with, and you will see the similarities to the dynaudio's.

I haven't looked up your tweeter, so not sure about sensitivity.

Tony.

It's going to require a lot of padding about 4dB's.
Morel CAW 538 5" Cast Frame Woofer 297-082
82.6 dB/2.83V/m
And not a great bass extension in a BR.
VB = 5.8 L, FB = 42.0 Hz, F3 = 61 Hz
Be careful... maybe that's for the TL guys.

Thanks!

I'll keep hunting then.

I'm using my MW144's in 5L (each) sealed in an MTM config tweeter (dms37 93db) is padded maybe 3db after baffle step on the woofers is taken care of... though I think the Mw144's are slightly more sensitive than their replacement.

F3 is around 80Hz... I figured if you were looking at 5" you would be using something at the low end (though admittedly I've been happily running with just the MTM's for a couple of years now, still haven't got the active crossovers for the bass done When I hooked up the prototype and listened to one, it definitely cleaned up the mids (which are already very good) so if you want the best from these drivers better not to run them all the way down. I was crossing at 200Hz.

Tony.

Give a good look at the 8" Volt. (86.1 dB/2.83V/m.) Also ScanSpeak is good. Set your preferences. Solen it's in Canada.
Dynaudio D260
Volt BM220.8

Thanks.
I had never even seen the Volt drivers before. Very interesting. I'll have to do some more reading on them.

I have also been recommended some other drivers. Anyone have any thoughts on these:

Scan-speak 15W/4531G
Seas H1520-08 U16RCY/P

Thanks
Erik

I'm not mentioning quality of sound, just technicalities.
Scan-speak higher sensitivity (85.9 dB/2.83V/m) and BR enclosure closer to a 7.5L.
Seas slight better low extension with BR enclosure of 12L and less SPL (83.6 dB/2.83V/m).

So of those two, likely the Scanspeak would be the better match?

I would like to keep the crossover as basic as I can.
