Trying Model T in room 2 - no subs running.

James,
I like this set up with 2x6BSST2.(if I am not wrong)
How do like them without subs?

[James Tanner]

Yes the 6B's are perfect - probably a little overkill on the tweets.

I wanted to try them in a smaller room (12/18 - long wall).  The nice thing about acoustic suspension speakers (sealed box - no ports) is they are really well controlled so it does not overload even a small room with low end which is usually the case with big speakers in small rooms. 

I am getting abour 25Hz at the low end so with the M80's I liked having the subs engaged but with the Model T - not needed!!!

Having fun

Sounds great

Hi Folks,

Here is the latest anechoic camber 'Listening Window' and 'Power Response' measurements of the Model T.

Hi James,

If I'm reading correctly, it looks liKe 30 Hz to 17 KHz +/- 3db is the frequency response.  In room, you would probably loose 2Kz or so off the top, due to absorbtion, so how does that impact their airiness, if it does, at all?

Hi,

Sounds very airy and spacious - the total power response is far more important that the direct on axis. That's why we feel the power response is more representative of overall frequency balance in a room.

Here's the M80 v3 test results:




This seems to highlight what I saw in the Model T response - the M80 does not have the rapid roll-off above 17kHz - any reason why the Model T does?  Though this may be a mut point given that you say the perceived extension in the treble is all there.

On the bass response, the M80 is definitely lumpier as you get below 60 Hz and drops off faster, which would make it likely less anchored in the bass frequencies then the Model T.  Though I'm sure with the active crossover in the Model T, transients are also that much more fast and impactful.

Hi SoundGame,

Yes the nice thing about the DSP crossover is you can really fine tune the frequency response to a much greater degree than with passive networks and so far this result sounds the most balanced.

Measurements are only indicators.

There are speakers that measures impressively on paper but doesn't sound as good - The real deal is to listen it in a room you are familiar with and make your own conclusion.

I think measurments are idicative of performance

Wonderful speakers, James.

Very much in line with my experience, for this reason I do demo of components that measure well and more or less ignore those that do not.

That makes sense...

Hi Folks,

So we are going to build a Passive version of the Model T and do some listening comparisons.

I have to ask why? Just curiosity or DSP cross-over did not fully meet the expectations?
