In Reply to: RE: I have a sub... posted by G Squared on December 28, 2020 at 12:15:14
I don't think I need a sub. If I stand up, there's plenty of bass. When I sit, most of it goes away, so clearly there's an issue with room acoustics.
Thinking about trying a Crown XLS 1502.
The problem is not that there is evil in the world, the problem is that there is good. Because otherwise, who would care?
Follow Ups:
Think you need to get your room acoustics addressed first.No matter the speaker or amp you'll never get an accurate representation of what their capable of.
Untreated rooms can have amazingly huge problems with frequency response .If you have frequency cancellations due to wall boundary interference no amount of power is going to help.Lots of info out there.
Well, what I call the back wall. Per the article you linked, it's the front wall. I've always referred to the wall behind the speakers as the back wall.
But moving them closer that wall helped tremendously. Moving them farther apart did, too.
The only issue I'm having with the amp is does it have enough power? That's all.

There were 3 options addressed
" To help you decide how far to put the speakers from your wall, use one of the three options given in this guide. Ideally, you will either
1. Flush mount them to eliminate boundary interference from the front wall. This is the only way to completely remove quarter wavelength cancellation caused by the wall behind your speakers.
2. Put them very close to the wall, moving the cancellation notch to a higher frequency so it can be tamed with absorption.
3.Place them far enough away from the wall so the cancellation notch is outside the frequency range your speakers reproduce."
Magnepans usually use option 3,5 or more feet from the wall,
because of being dipoles.
Anyway the point I was making is that if your speakers and room setup is creating all kinds of cancellation notch's in the frequency due to room boundary issues more power wont help.
Good luck.
Moved them back about a foot and a half towards the wall behind them and away from my listening position and that seems to have fixed the issues with the bass.
Plenty of it, and it no longer changes when I'm standing or sitting.
Thanks for your help!

Glad it's all good.Enjoy.
Found a problem with my pre-amp. Channel imbalance with a bit of distortion on the left side. Got the backup in the system right now.
Been looking for an excuse to send it off to Musical Concepts....

Another stimulus check soon for you to stimulate those Maggies with more power.
You only live once or so.
LOTS of good Class D info to the left of this page.

if it's $600, it's going into my grandkids 529 account.
If it's $2000, then I can deal.

If changing ear position changes bass it has nothing to do with the amp. It is a speaker/room interaction problem and probably means repositioning your speakers/seat/room set up.
You're right about the amp. Changing amps won't fix the bass "hole;" that's purely room acoustics.
My amp is a Hafler DH-200. It's rated at 100 wpc into 8 ohms and 175 wpc into 4 ohms. Doesn't double into four ohms which is usually the rule of thumb with Maggies.
Even though it's an old amp, I had it rebuilt two or three years ago. Sometimes, and this might just be my imagination, the amp seems like it's straining to drive the Maggies. Again, my brain might be making my ears hear something that isn't happening. The Hafler has those capacitors about the size of beer cans.
At any rate, the goal with the Elacs was to eliminate the bass hole, which they actually did, and be easier to drive than MMGs, which they were. Unfortunately, they were just too small to fill the room. Bass was no problem, those little woofers generated enough bass to be felt through the floor upstairs. The problem was more like size if that makes any sense. The image they threw just wasn't big enough. With Maggies, the sound comes from everywhere, like a tornado of sound. The Elacs couldn't do that.
Otherwise, they're excellent speakers. Not just for the price, but excellent period. If I had a second system in smaller room, I'd have kept them.
In the meantime, I think I have the bass issue with the MMGs solved. Moved some furniture, repositioned the Maggies closer to the back wall and farther apart. Played The Poll Winners Ride Again last night and the bass was thumping, even in the "hole."

Ask on planar. Folks have tried Crowns Maggie's. I ran a DC 300 for years.

People either love them or hate them.
There's an XLS 2000 for sale at USA Audiomart. That's got more power than the starship Enterprise into 4 ohms. Dunno. Giving it deeep thought.

Sounds like fun. Maggie's eat it.
