Tekton Double Impacts

I am interested as well, EXCEPT there is no midrange dedicated driver, its all tweeters?  why?

Hi Al, 

The amp you sent the specs on is the same MKII version but Triode told me the input impedance is 220K. They said they can make it 100K but it would hurt the bass.

The Truth recommends 100K or more if I remember right.

Will that be a benefit for volume or other performance factors with a higher input impedance?

Thanks,
   LP

Arcticdeth,

There are actually two sets of drivers handling the midrange. Only one of the tweeters is handling the highs, the other six handle the upper mids and there are two 6" drivers handling the lower mids. The DI's are exceptional at conveying midrange......and bass.....and highs ;)

Lpretiring, is the Truth that you have what is described on the page I linked to above?  If so, its very low output impedance would make any reasonable load impedance (i.e., amplifier input impedance) a non-issue.  Impedance compatibility issues, btw, if present may affect tonality, bass response, and other sonic characteristics, but would not affect volume levels to a significant degree.

In any event, aside from certain unusual circumstances higher amplifier input impedances are preferable to lower input impedances, so 220K should be fine.   

I'm not sure what to make of your characterization of the unusual action of the Truth's volume control.  But assuming as I said that the specs on everything are reasonably accurate you'll probably find that to achieve a given volume level with the new speakers and amp you would have to set the volume control higher than at present by an amount that with the present equipment would correspond to a small but readily noticeable volume increase.

Regarding your more general question about gain, sensitivity, and power, the gains of the preamp and power amp, the sensitivity of the speakers, and the output level of the source component will together determine the position of the volume control at which a desired volume level is reached.  Assuming, that is, that the desired volume level is obtainable without exceeding the amp's maximum power capability, or the power handling capability of the speaker. 

The power capability of the amp together with the sensitivity and other characteristics of the speaker and the room, as well as the listening distance, will determine the maximum listening volume that can be generated without the amplifier starting to clip and distort, as it starts to run out of power.  The setting of the volume control at which that maximum volume capability is reached will in turn depend on the gains, sensitivities, and source output level I referred to in the previous paragraph.

All that being said, in general the main concern I would have in using a 3.5 watt amp with 92 db/1 watt/1 meter speakers is not having enough power, rather than not having enough gain.  For me that combination would be a non-starter (see my two posts in this thread dated 7-17-2017), but depending on listening distance, preferred volume levels, room size, and the dynamic range of the recordings that are listened to I'd expect it would be suitable for many listeners.

Good luck.  Regards,

articdeth,
to add to what mac said understand the 6 tweeter array extends far lower into the midrange  than you would ever guess.  That is one of this speakers key design elements
