    Default The Tower Discussion Thread!

    With our first set of towers being delivered today, I thought it was time to dedicate a thread to our exciting new loudspeaker.

    I will do my best to post as much information as possible and answer as many questions as I am able.

    But first a few pictures (sorry for the bad quality on this first set of shots)

    Default Measurements

    Attached is an in-room frequency response measurement taken in our listening room. The microphone distance is 2 meters and the speaker is positioned 3 feet in front of the wall behind it.

    A few important comments:

    1. The two large dips (one at 70Hz and the other at 250Hz) are room reflections and should be ignored.

    2. Note the incredibly flat frequency response and impressive high frequency extension. In our well treated listening room and at 2 meters distance, the high frequency response is -3dB at 27kHz. 1" and even smaller soft dome tweeters are typically at least -10dB at 20kHz @ 1 meter in-room - and as much as -16dB at 2 meters due to high frequency losses.

    3. While the speaker has not been designed for deep bass, in-room and positioned so there is little bass reinforcement from the front wall, the speaker is -3dB at 34Hz. Anechoic bass response is -3dB at 41Hz.

    4. Typical in-room sensitivity is 92dB at 2.83v at 1 meter. Anechoic sensitivity is 89dB at 2.83v at 1 meter.

    5. Minimum impedance = 4 ohms with a nominal impedance of 6 ohms. The impedance response is smooth and free of any artifacts (wrinkles) which would indicate potential resonance problems, thanks in part to the bamboo cabinet and exceptional transducers In addition, the electrical phase angle never exceeds +/- 30 degrees which means despite the 4 ohm minimum impedance, the speaker will work well with most 8 ohm rated receivers.

    And just a few more specifications:

    Shipping weight = 57 pounds each (although this may change slightly as we are still finalizing the packaging details.)

    Dimensions = 43" high x 7.5" wide x 10.5" deep

    Loudspeaker power handling = massive! (we have yet to reach the speaker's limits but I would estimate it to be about 350 clean watts)

    Those speakers are beautiful. What color is that considered?? Are you going to post some pictures with other colors that are avilable ? Are these the pictures of Brandon's speakers ?? Sorry for all the questions, but getting excited about what Brandon is going to say about them. I'm not sure if i missed what equipment he would be playing them on.

    Thanks Rich

    Rich,
    For you and anyone else wondering what equipment I will be running these with:
    Proceed amp3 for front 3 channels - 150w/ch at 8ohm, 250w at 4ohm
    Parasound 2100 preamp with HT bypass & yamaha Rx-v2600 for movies
    Squeezebox Touch (source)
    Oppo 981 DVD player for SACD & DVD_Audio
    Rythmik D-15SE sub EQ'ed very flat with Behringer FD

    Curtis - I recall you mentioned you heard a prototype? Have you heard this recent production model as well? Initial reviews were very positive.

    Brandon: If I remember correctly you are using Sierra-1s (non-Nrt) as your surrounds, how do you have them placed - wall mounted or on stands? After few emails back and forth to Dave and advice from Cutris I might just stick with direct radiating/monopoles for my surrounds instead of dipoles and ideally would like Sierra-1s as surrounds if I go with monopoles to match new towers but not sure about the look of wall mounted Sierra-1s due to their depth.

    You are correct. They are wall mounted using the Btech77 mounts. They make great surround speakers for Multi Ch music and Blu-ray movies.

    See this thread for more info and pics....

    Would I be correct in thinking that someone planning on 96% home theater would be better off going with NRT over RAAL?

    Center would be a Sierra-1 with NRT. Unless Dave finishes up that 'bookshelf/RAAL' he's been hinting at for some time now.
