To Raise or Not to Raise Heresy IV's


I've noticed the speaker cabinets moan a bit in the lower reaches of their range with or without a sub when they are on the floor and this has really started to annoy me.  Ive been contemplating raising the H4's to get rid of this moaning, but the general consensus is that raising them will cause the bass to evaporate. I figured, if I'm using a sub anyway why should I care if the bass evaporates; I'll  just bump up the sub. 

I brought in 4 cinderblocks and removed the H4 stands. Initially it sounds fantastic and the moaning is gone.

What's my point in all of this? I was hesitant because of the opinions of others, but I tried it and I think there is very nice improvement, so.....if you use a sub and have vaguely considered raising your H4's, but have been worried about negative opinions, I think it is worth a shot.

Tony , they could be too close to the rear wall or corner.  Make sure any tone controls are set to zero and mess around with placement 

In my experience with H2 and H3 they work well on the floor, ru ning full range with the subs crossover low , like 40 or 50 hz.    When you run a sub at a high crossover frequency , the sub starts to become directional...   you can tell where it is in the room and thats something you want to avoid if possible. 

 

The Heresy IV is the first ported Heresy so you might be hearing some port noise, perhaps pulling it away from the wall will help

"Tony , they could be too close to the rear wall or corner." 

They are three feet off the wall. I spent a long time getting the proper distance. BTW the soundstage increased in depth too by raising the speakers.

I have no tone controls.

 

"In my experience with H2 and H3 they work well on the floor, running full range with the subs crossover low , like 40 or 50 hz." 

 

I had them on 50 before, I had to increase them to 60 to cover the loss.

This has not happened. Sounds great all around. Much better than it was and I thought it was great before.

 

Thanks for your comments.

It’s not an entirely uncommon practice for people to raise them.

Trust your ears.
