    Default HTM 200SEs as Near field Monitors

    I'm planning to get a pair of speakers for my desktop at work. I was originally thinking of getting the Audioengine A5+, since they seem to be the highly regarded in their price point. But then I started thinking, what if instead I got a pair of HTM 200 SE's. I could get an amplifier like the Audioengine N22,

    https://audioengineusa.com/shop/ampl...dio-amplifier/,

    to power the speakers. The N22 seems kind of pricey, but I did find some new models selling on ebay and such for around $150.

    How would the HTM 200SE's work as a desktop speaker?

    How would they compare to the Audioengine speakers, which are designed specifically for this use?

    Can anyone suggest a speaker/headphone amplifier at this price point or less that would work well with the HTM200SE's? I was thinking about getting some planar magnetic headphones next year, so the headphone amp would be a nice plus with the N22.

    I did see a Monoprice tube amp that seems to have similar performance to the N22. Just not sure if it is a quality unit or not. Looks really cool though. It wouldn't be as easy to hookup to the computer though and it is a little bulkier.

    My son has been using a pair of HTM-200's on his desktop and this amp.

    I have been quite impressed with this combination.

    I know that the quality of the drivers and likely the crossover in the HTM 200s surpass that in the Audioengine speakers. The cost of either speakers would end up being very similar. Is there any reason to think that the HTM 200s can’t sound as good or better than speakers designed specifically for nearfield use? They would be within arms length.

    All of our speakers are designed with very tight phase integration between the drivers. That's what basically defines the difference between a speaker designed for nearfield usage and one that isn't specifically designed for it. So yes, without question, our HTM-200's will perform exceptionally well as nearfield speakers and we have many hundreds of customers using them as desktop nearfield speakers.

    Thanks Dave. This is very helpful. I think that I will go the route of HTM-200's for my desktop speakers.

    I do have another question that is connected with what you brought up though. I've heard conflicting answers on phase integration of the subwoofer with the main speakers. Some say that not having them phase aligned would be noticeable. However, others say that it is not something that is noticeable with bass 80 Hz and below. In fact, they suggest using the phase as a way of altering the wave interaction in the room and thus moving the standing waves away from the seating area with a single subwoofer.

    Or doing so similarly with say two subwoofers. Place the two subwoofers in locations that are available in the room, leave one phase knob at 0 degrees and play with the phase knob on the other subwoofer. This would alter the wave interaction in the room and allow you to move the standing waves away from the seating locations as much as possible and usually ending up with similar frequency response from one seat to the next, which can then be globally EQ'ed. This is what can be done in a room that is not sealed and rectangular, where the best locations to place the subwoofers are known, from Harmon's research. With each seat having similar response, one can then use room EQ to get similar response from seat to seat, if the subs are EQ'ed as a mono subwoofer and can also be phase aligned with the main speakers as a mono subwoofer. But, are the two subs really phase aligned with the woofers in the main speakers at that point?

    Phase integration between the main speakers and subwoofer when using bass management would be noticeable with in-room measurements. If they are not in perfect phase, than you will end up with frequency response issues at the crossover point and typically up to a half octave above and below. Now, perfect phase alignment between sources at different locations is only possible at one location. So if you manage to achieve perfect phase alignment between speaker and sub at one location, as soon as you move out of that location - you can no longer have perfect phase alignment. I can not say one way or another if this is audible or not, that can only be determined by the listener. It is actually quite complex with far too many variables at play.

    As far as "moving standing waves" - I suppose in theory, and with proper measurement equipment, one can use multiple subwoofers, each with having a way to adjust phase at a specific frequency (would require very precise DSP) to reduce the amplitude of a specific standing wave frequency or change the timing such that at a specific point in the room the listener would be in a node rather than an antinode. However, I can't even begin to imagine the complexity of this.

    Problem is that rooms will have multiple standing waves, all at different frequencies -- resolve one and you cause issues at with others...

    My youngest just built a desktop PC for her VR system. I'm pretty sure I still have that pair of white 200s you built a decade ago, for another member, tucked away somewhere. I may order that amp for her.
