My New Review of the Spatial Hologram M4 Open Baffle Speaker

I love that the Spatials use two 12" bass drivers, are open baffle, use a concentric mounted compression driver, and are comparably efficient as a result. Seems like a nicely thought out design compatible with most amps and worth hearing.

I recall the DIYers at an audio show a few years back demoed much smaller home made open baffle speakers made from a couple hundred dollars worth of parts that was one of the most uniquely engaging sounds at the show. They sat just above floor level for bass reinforcement and with open baffle angled slightly up for high frequencies. Very unconventional yet practical and delivered the goods! The big name high priced dealers there must have hated that room.

It re-confirmed to me what I always thought that with just a bit of out-of the-box thinking, things need not be massive and uber expensive to sound great.

I like to shoot for the sky usually when it comes to these things as much as I can.   Bigger done well is usually better but also more expensive.    We’ll see. I’ve got some reading to do.

Maggies on steroids is largely what I was looking for to end up where I am today. Sounds good to me!

I would really like to hear these. Might have to pick up a pair just because I can.

Hey yesterday I was twiddling with the speakers in my wife’s sunroom (switching in an old pair of Boston A40 sereis II I had just re-foamed to try) and my wife asked out of nowhere if I could put a pair of white speakers in there to match the decor better.

So there you go. The wife is asking for a new pair of speakers. What can I say except OK? Now I gotta show her a picture of the Holograms and get a reaction. They are much bigger that what’s in there now.

Also I have had floor interaction problems with every pair of speakers I’ve tried in there. The Holograms are likely no different. I’d need to find an isolating platform of some sort that fit them. My current Isoacoustics brand monitor stands in there would not.

BTW in the initial audition, the little old Boston’s sounded really good in there! I recall their sound from about 30 years back when I bought them and had high hopes for them in the sun room. They did not disappoint. These little old babys are sounding very smooth yet detailed! The tonality reminded me of Goldenear Aon speakers I have heard and liked recently. The re-foaming really did the job! But the wife wants white speakers so there you go.

Has anyone heard the difference between turbo and turbo s models?  Turbo S uses more expensive compression driver apparently but what is the difference in the sound I wonder?

Hmm not as big as I thought which is a good thing for that room.  

Thanks.  

Fin in have you heard them?   Are you an owner?

Anyone tried corner placement with any Spatials?
