Open-back / open baffle revisit

I’d really like to just find a pair of Maggie LRS+ and redo the crossover, bi-amp combo active/passive, but I’m fairly confident I’d a) find myself needing to build that front-room plantstand (hidden sub) that my wife has always never wanted, and b) would agree that at 48 inches they are just too tall / big for our living room.

So next up would be something in line with a trimmed down PureAudioProject TRIO10, and with a little EQ I think I could get them down to within my size constraints. And I found just the woofers up for the job; the faitalPRO 10RS430s except for the price, especially if I ended up really needing that plantstand anyway…

But I do have a quad of the Beyma 12’s from my older open back project, wood and the time, so I’m off to see just how small I can make these and then compare vs my current dual 8in sealed woofer boxes. Knowing that they are still going to be too big, (looking like 36 inches height, still better than my originals at 42 height) it’s a relatively free exercise since I have the stuff, and if they get the low-end extension I’m looking for in our room then maybe give the 10’s a go. If not, probably best to keep my open back sound to the midrange and above, and sealed 8’s below.

if not going for big woofers, seems like alot of quiet excursion is what is needed. High Qts unless going active.

Set for testing / comp the OB 12s vs the sealed dual 8s (one rearward facing). Just put in a ‘plug baffle’ for where the coaxial would go at this point. Kept them to 35 inch height, but still looking a bit large? Maybe if / when they have a black grill they’d look smaller.

I think they should fit well flanking your fireplace mantle Andy. Black grills will help for sure.

Same coax MT’s?

Might be losing a little gain by not having the baffle touch the floor.

Yes, I’d just pull them (and it’s Xover) from current build.

The top and bottom will both be 1.5 ways.

It was fairly easy to EQ the OB’s to match the sealed 8s (with no visible excursion at volume on the Beyma 12s). These are measurements from listening location (~ 12 feet back).

And thanks for the suggestion. I had it raised to keep from sweeper / cleaning floor issues, but dropping a bit, as well as being able to take maybe an inch out of the top baffle (for the coaxial) will get overall height down to approximately 33.5 inches (more acceptable ).

Those sounded smooth and very well balanced to me. I’m hoping the new OB woofers can fill your space (nice open floor plan with high ceilings).

Thx.
Playing/comparing the OB’s with the coaxial on the left side, and the sealed speaker on the right.

Looks (sounds) like I’m going to have to make the right speaker now and get onto the grills.
