Life After Your Magnepan’s

Check out Tekton Moabs or Ulfberhts.  They will fill that large room with great sound that won't have you missing your Magnepans at all.

I had a love hate relationship with Maggie 3.5Rs. Previously, I owned Accoustat 2 + 2s and am a huge open baffle fan. My room is quite large and I tried various subs with various main speakers. I tried various amps here as well, even biamping the 3.5s tweeter and bass panels, plus the 2 SVS powered 12" subs, but could not get them to blend seamlessly. I also tried active XOs, but the cheap ones kept blowing up and a Marchand XLR was uber expensive.

After considerable research I bought Emerald Physics KCIIs which are open baffle (and considerably smaller ~ 43" tall: 93dB efficient, but can handle big power. I find them similarly open and fast, a touch warmer sounding than the 3.5s.

I gave up trying to use the subs, still, the KCIIs sound terrific, especially with my EVS 1200 class D amp (600wpc!). They can be a bit overwhelmed with large scale music in MY ROOM, which is 19 X 38ish with a 12ft peak in the open beam ceiling.


Right now EP is running a factory direct sale: the EP2.8s with dual 15" carbon fiber woofers, and 12" concentric carbon fiber mid-range which should be killer. MSRP $9999, BUT, until they are gone $4999 including delivery That is an amazing bargain

One of the reasons Maggies sound so good is that they generate a lot of spectrally-correct backwave energy. When placed well out into the room, that backwave energy arrives after a relatively long time delay, which is desirable. This mimics, on a smaller scale, what we find in a good seat in a good concert hall: A time-gap in between the direct sound and the strong onset of reflections. According to researcher David Griesinger, the ear being able to separate out the direct sound from the reflections is highly beneficial, and is largely what differentiates a good seat from a bad one in a concert hall.

In a home audio setting, there is a competition between two sets of venue cues: The venue cues on the recording (whether real or engineered); and the acoustic signature of the listening room. In order for the venue cues on the recording to dominate our perception and enable that elusive "you are there" illusion with a good recording, they must be presented effectively, while the listening room’s inherent "small room signature" is minimized. The backwave of the Maggies can present the recording venue cues effectively, and the long time delay from proper placement tends to minimize "small room signature", so Maggies set up properly can be very enjoyable.

One of the things an acoustician does in a home audio setting is minimize the early reflections while preserving that energy so it can come back as later reflections. This is conceptually similar to what a good dipole does when set up properly.

Because it is spectrally correct the backwave also enhances timbre, which again is something reflections do in a good concert or recital hall.

I realize none of this speaks directly to the question of "what to get after Maggies", but perhaps awareness of what the backwave can contribute is helpful.

@audiokinesis   Thank you for your very helpful post. 

Try the largest Spatial Audio model you can afford.

If bass is too light, they can be augmented with open-baffle subs like those designed by GR Research.
