This is a somewhat timely thread since I received this email this afternoon from a customer who just upgraded from the HT2-TL's to the HT3's...
"...I also wanted to share with you my first impressions on the HT3's vs the HT2-TL's. I feel that they are probably one of the most accurate speakers I have ever heard. They are power hungry compared to the HT2-TL. The HT3's take everything my McIntosh MC402 has to offer and I can tell they want more. But man what a difference. I believe they are on a completely higher playing field compared to HT2-TL's. Both are great speakers but I am just totally impressed by the HT3'S, and there is probably more to come once they are broke in. As far as an upgade I feel they are worth every penny."
So this is always a tough question to answer. There are pros and cons of going with any given speaker design.
A few years back, I had a customer who wanted SongTowers and I thought they would be a good match for him. Later, after he upgraded to the HT2-TL's, he gave me good-natured grief for selling him the wrong speakers in the first place. So I have to watch my tendency to try and determine the least costly path for customers. I don't want to sell them short.
In this case, there are some advantages to the HT3's. But they do require more power. A 4db difference in sensitivity may not sound like much, but you need more than twice the power to reach the same SPL levels. I don't think they would be a good match for the UPA amps. Another thing to consider is that they are somewhat harder to place in a room since they are rear ported and not a transmission line.
While they weigh and cost a bit more, the SoundScape 8's should be considered as well. They don't place as much demand on amplification (being roughly the same sensitivity as the HT2-TL's) and they are very easy to place in a room (due to the horizontally-opposed passives). They are also slightly narrower than the HT3's which some people might find advantageous.
All that said, the HT2-TL's, especially with a good sub, do a very good job indeed.
Hopefully this will help.
