Altec 510 reviews?

I would go 604 or model 19.

I have a multi use system based on the Alec Lansing speakers.
I the 511's in front.
2 65's for the center.
My 508's that used to be my fronts are now the side speakers.
And a pair of 115's for the rears.
I've always liked the sound of the Altec's manufactured in PA over the horns or most other speakers in general.
I would asume that although the 510's are made overseas and have been updated they most likely would sound simalar to the others in the series.
To me these speakers are great for all types of music but they do tend to sound better as the volume goes past the easy listening level.
They also like lots of power.

I had a pair of 510As recently and I thought they were pretty nice. Not the most revealing but well balanced and powerful sounding, with a large soundstage. I had a pair of 508s many years ago. I think they sounded very similar, with the larger 510 having deeper bass, of course. I agree that they need some good power to get going.
They don't sound anything like the old altec horn systems, of course.
If you like their big sound I don't know of much under $1500 used that would improve on them. Possibly Von Schweikert VR2s or Thiel 3.6s, for $1200-1700 used would be the next step up giving you the image size and power of the 510s with better resolution.

Thanks for your responses! Back in the early 80's my brother had trialed the Altec 14's and the 19's. The 14's won out. Then the 511's came into the picture. I heard them both in the same room. The 511's had a much fuller sound overall - not the pop you get from the horns but not shrill either. He sent the 14's down the road with another brother who also switched to the 511. Gave them to yet another brother who put them in the garage. So..long story short, I have the newer 510's and like them but was curious about the 604's until I read that the 604's do not sound that full and open at low volumes. Again, I haven't heard them myself. Sounds like you all are very satisfied with the 511/510 but I am curious as to what Jmbatkh did with his setup and why he may have gotten rid of the 510's. Did you find something better or go to horn loaded? By the way..on another thread on 'best speakers you ever heard' I have been convinced to join the gym vs sinking into the abyss of continual pursuit of better speakers. But I still like to hear others opinions on their experience with these altec towers.
