I've been sitting on a pair of Pinnacle Baby Boomer that I've coupled with a pair of Omega Super 3i for a few months. Though the pairing has given me the best sound i've yet gotten after about a dozen speaker setups, I did not have confidence to recommend the Baby Boomers until now. This is the first setup that I told my wife, 'OK, I've arrived. I'm done - except one final system on the radar which I've committed to testing way back since May."
I currently have a pair of Devialet Phantoms that is famed for its bass reproduction. It's now between the Phantoms and the Omega/Pinnacle pairing. I can actually sell off my rig for more than the Phantoms will cost me. It is down to one of these two system.
Now that I have a baseline for comparison using the Phantoms, I can heartily recommend the Pinnacle Baby Boomers.
I jumped on them a couple of years ago because on paper, they looked like they should be very fast:
1. Sealed.
2. Dual opposing drivers to cancel out vibration.
3. 8" drivers so they are small and lighweight. (i.e. fast)
4. 600 watts - though that's probably peak-peak.
5. Small - and thus easy to place around the room.
I raise the Pinnacles almost 20" off the ground using concrete blocks and run them full range straight out of my Line Magnetic 502ca DAC. Raising them off the ground, I believe, makes them sound very clean.
I listen primarily to acoustically driven music so speed, timbre, resolution etc all matters to me.
In short, the pair of Baby Boomers gives me more weight in the bass, and seem to give me more resolution and weight than the Phantom's bass. The Phantoms do have fatter/fuller mids than the Omega Super 3i - but both systems give some and gain some. Both are excellent. My guess is that Alnico monitors coupled with the Baby Boomers would be ideal to have a bit more midrange weight but the Super 3i are already quite incredible. I sold my KEF LS50 when the Super 3i arrived. And that's just based on audio quality - not price.
A couple of years ago, you can pick up the Pinnacle Baby Boomers through one of Amazon's affiliates for a less but I see that they have since gone up in price to about $400 for a new unit. I believe at that price they are still a bargain. A pair at $800 (less if you purchase used) and you have superb bass reinforcement.
I note that I've read some who thought that the 3i sounds 'small'. To me, they project a large soundstage - but I feel that bass reinforcement is what makes them sound large. I have no complaint about soundstage size - and this is one criteria that is important to me which is why I moved away from headphones though they have high resolution.
Caveats:
1. Caution - of course, your mileage may vary. I may not have golden ears though I am well attuned to acoustic music.
2. The Phantoms are not optimized yet so I'll update this post if I find the Phantom bass to be better.
3. Caution - Phantoms are not for the fainthearted. Be prepared to spend many hours trying to make it to work - their software is required for stereo AND is extremely buggy. If you already have high blood pressure, I recommend you just steer clear of Devialet Phantoms....
This is widely acknowledged by Phantom owners.
4. Baby Boomers are probably not for huge rooms - but then the Omega Super 3i are not either though if you crossover the 3i at 100hz and up, I think you can probably drive them to deafening levels. I don't. My music is more sane in volume but I do want the quality.

ps: In the past, when I read online that some consider Omegas to be a bargain, I chalked that up to hyperbole. But after having heard a couple of Omega systems, I will say that's true. (Though it doesn't prevent me from still seeking great deals on Omegas so that I don't take a bath on resale.
) They are just wonderful - there's something very right/correct about the music through the Omegas. It is unfortunate that Louis probably does not get more looks because many shy away from single driver speakers.
Thank you Louis for bringing so much joy to my listening room.
