Seas Thor vs. Proac 2.5 Clone

[thomap]

I am considering building a speaker system and after having read quite a few discussions I am left with these two projects:

Seas Thor
ProAc 2.5 Clone

I mosly listen to Jazz, Pop, Rock + some classical. The room is quite large, about 55 m2. I have a moderate 60W transistor amplifyer, but am also considering to upgrade this to a more powerful power amp.

I know that the Thor is quite a bit more expensive, but due to the size of the room, should I go for the TMT Thor instead of the smaller ProAc?

Thanks for input!

Hi,

The tradeoff for great bass of the ProAc Response 2.5 and clone is the speaker's relatively low sensitivity.

I have my ProAc clones in a medium-large 6x9(54m^2)x2.7m living room, which opens into a kitchen. I use 90Wx2 which is loud enough for many people, but it does not reach lifelike/live levels without. When pushed hard is sounds constrained or compressed. A single 7" woofer can only do so much.

I much prefer my ProAclone in our smaller formal dining room. (~30m^2)

Based on higher sensitivity and power handling alone, I would recommend the Thor for larger rooms. I have not heard the Thor, but fortunately, they are great on almost all accounts.

Hi thomap,
Hi tktran

I found someone who use Seas Thor. He told me that Thor has a great sound. It has natural, detail bass and could go deep as he want but slightly lean. I'm trying to set schedule to visit him and I will brough Pink Floy, The Eagles, and some fusion jazz CDs to test the Thor. I'll post my review after that.

Alot of that would probably go away if the enclosure was restored to its originally designed size.... Joe reduced the box by a 1/3 in actual implementation.

Hi Dave,
Where can I get a corrected plan?

I haven't seen one... basically you increase the cross-section by the appropriate amount... i'd have to go back to the audioXpress article and see if by a 1.3 i mean increase by 33% (my 1st guess) or by 50%. You'd also have to deal with redoing the dimensions at the fold.

You'd be even better off to just optimize a line using Martin king's software... i'm also of the opion (completely unfounded on anything but my experienced conjecture) that the drivers would be better in a 2.5 way with the 0.5 driver mounted push-push wrt to the midbass that reache sup to the tweeter. Some rework of the XO would be required thou.

I am trying to make the same decision so will appreciate any comments on the forum. I will be using an aragon preamp/amp or if part of my home theater a Harmon Kardon 70w receiver. Seems like SS amps might be a problem with the Proac.

Comments from you DIY'ers?

Thanks in advance

I had listen to Seas Thor last weekend. The result is same as i mention above (lean bass). I think this speaker is good for acoustic music, vocal, not for pop, rock, orchrestra.

This is similar to my experience too. I have the Thor, and in my opinion it is a great speaker, but as you said a bit "lean bass". Although, I'd really like to hear them in a bigger room then my living room (21 kvm), and place further away from the back wall then I can in my appartment. I think this would have given even better result in the "bass area".

Hearing them in a bigger box would also be interesting.
