Hey Guys,
I've bought a pair of B&O Type K speakers. They are in fine condition and I love the way they look.
The cabinet is particle board and approx. 100 liters. There is no brazing.
I am looking for advice to make them into a sleeper speaker - you know, kind of like an old car that looks old on the outside, but is high-performance on the inside.
I listen to a lot of electronic and ambient music so bass is important. Hopefully down to 30hz. I favor musicality over neutrality.
I have a couple of ideas to get there, but welcome any other suggestions:
1: Put a pair of EMS LB12MK2 in each and call it a day. I don't know if they will work in that cabinet. I'll be changing the front and back baffle so I can make any kind of port or passive radiator. I've found a pair of the LB12EX (the field coil version) for a good price, and could also contemplate those, but at €1800,- for the pair I'm basically over my limit.
2: Putting two Seas A26 in series or parallel in each speaker, plus a tweeter or a small fullrange driver from e.g. Markaudio etc. (I've already received great advice on this config. from this thread: https://www.diyaudio.com/community/threads/seas-a26-devore-style-build.369124/page-18#post-7151096 )
3: A pair of Scanspeak 30W/4558T00 that I have laying around with a fullrange driver. Crossover at somewhere between 200-600 hz.
4: A 12" ferrite fullrange driver from Audio Nirvana that is on sale here in Denmark.
5: And finally, a 12"-15" coaxial driver and a really careful (active?) crossover.
With the multiway options above I'm not completely adverse to going active.
Are there some knowledgeable people out there who can point me in the right direction? I'm a novice, so managing the demand for really nice sound with my limited skill is probably the real challenge here. Which - even though I've posted this the Multiway forum - makes me somewhat partial to a fullrange solution.
Anyway, hope you will chime in. I'll post some pics of the Type K speakers below. And let my quickly add: I'll save the original drivers and crossover and front and back baffle so the speakers can be brought back to original again🙂
Kind regards
Mads

Yes sir🙂 And yes, the box is flimsy. Thank you for all your advice in that thread. The double A26 and tweeter is still, I think, my preferred way forward 👍

Hey,
I didn't know about that. So thanks. There's chatter various places about the Osprey, but I can't find it at the Ampslab website...
Thank you for your reply. Well, I like the recycle / upcycle aspect of taking an old cabinet and giving it a new and extended life. Also, I don't have skills to make a precise knockoff.
As they are, the speakers sound distant and dry, with poor dynamics. I'm considering, giving them a new crossover and giving them a chance as a simply a restored classic, but I'm very worried that they won't be worth the effort...
My understanding is they are upgrading the website. Contact Michael. All the info, the measurements, crossover, was on the site.
Next question then. Taking out the mid and tweeter what's the bass like?
One of my main "tinkers" is taking out the enclosed back mid and putting in a driver in it's own enclosure and then adjusting the XO down as low as the new mid driver will play, changing the point from around 600 or 800 to as low as 300Hz. High cost in XO parts tho and a good midrange is often expensive but not always
