Power sound audio released the specs and preorder for their new towers last night, the MTM210T.
They look like behemoths! I must say though, initially looking at the specs, I'm a bit disappointed.
I understand they aren't in the business of full range towers as they are a sub manufacturer, but these speakers tout 2 10" drivers and 1 compression tweeter. They are 52"h 11"w and 16"d.
However, specs only rate them to 60hz. Interesting choice I thought. After all, there isn't very much need for towers in a home theater environment. I would think the release of a tower would indicate a bit of a 2 channel market.
Thoughts?

Actually I think they took the perfect approach for a HT tower where it's all about dynamic impact at every frequency. If you've ever heard the JBL Everest or K2 playing the "Open Range" gun fight scene you would be very impressed by the dynamic realism. For music, a design like the Revel Salon/Studio is better. Ymmv.

they merely were catering to the crowd that didn't want to buy stands...nothing more...nothing groundbreaking meant to be released...so no need to be disappointed..  90% of those with a HT setup in their home is not in a dedicated room...so towers are the easiest for them and most appealing..in fact the mtm210's main reason someone passed on them was lack of stands etc. and I personally am in the camp..."i dont care how low the speakers go"..you are better off with a dedicated sub or 2...to get the best response full range |

Not bashing them, I love my PSA gear. However, why not a little more low end in such a large tower? You have to admit, it does beg the question. Almost a missed opportunity. My speakers have great response to 60hz, but still I leave them crossed at 80hz. However, in a tower "most" people are looking for better low end response. For instance, I would love to own a PSA tower for a 2 channel system, which I am currently building on top of my HT room. Either way, just thought it was a little funny. |

Are your towers sealed?

It seems to me they decided to offer higher efficiency (98dB @ 1W/1m, holy cow!) at the expense of low end extension. This was also probably dictated by the use of a compression driver. Even with two woofers I guess they had to push the efficiency on mids and lows to keep up with the highs driver.
As others have said, the "limited" extension can be easily fixed with a good sub anyway.
Or maybe they just do not want to eat into their sub business :-)

This is rhetorical? I take it by your question, that you are actually making a statement about the MTM210T's design? |

I was wondering if your speakers were ported or sealed. Ported will dig lower than sealed.
Psa made the conscience choice to stay sealed for various reasons

That's for subs. And super low frequencies
Sealed speakers have the same shaped response as subs. But the subs rely on room gain to dig deep.
Room gain doesn't effect the frequencies of speakers the same

Psa made the conscience choice to stay sealed for various reasons I thought sealed goes lower than ported, but ported plays louder? Sealed speakers tend to have shallower slope compared to ported. So yes, sealed speakers typically go lower, whereas ported speakers typically have higher output to their tuning frequency and drop off at a much faster rate below that. |

Well I've only read about sealed versus ported with subs, and never really thought about regular speakers. Bmoney says the opposite of what you say, so I'll let you two argue about that. |

A sealed sub ONLY goes lower than ported due to the room gain boosting the lower frequencies (this is why sealed isn't recommended for large rooms) otherwise if you look at their native response, a ported sub actually extends deeper (in an open field)
The native responses are the same for speakers. But room gain only works in the lowest of octaves. M
Have you ever heard a sealed speaker isn't duties for a large room? No
Also some recommend to plug a speaker port to make bass tighter at the expense of extension
So for speakers yes ported extend deeper than sealed

No Also some recommend to plug a speaker port to make bass tighter at the expense of extension So for speakers yes ported extend deeper than sealed Both sealed and ported speakers are affected by room gain. Regardless, ported speakers DO have higher output than sealed speakers. That's not the argument. The fact is, at any given output level, the ported speaker has a typical roll off rate of 24dB per octave below it's tuned frequency. This is TWICE the rate of a sealed enclosure. Here's are couple CEA2010 output results from two SVS subs. Both have identical drivers and amps. The first one is ported (And it happens to be the one I use. The other is it's sealed sibling. The results are quite clear. The ported DOES have higher output, but please notice the greater bass extension of the sealed system.   |

I understand they both get benefits of room gain FOR SUBS but sealed much more. No disputing your point. I am not talking about subs in this thread
The frequencies of speakers don't utilize room gain like a sub.

I understand this thread isn't about subs, but they easily demonstrate the effect two common enclosure types effect on bass response. Acoustical physics effect "speakers" and subs the exact same way. |

i guess you arent understanding what IM saying
the physics are EXACTLY the same ...however...speakers do NOT take advantage of room gain...room gain is only highly advantageous to the low frequency ...general speaker frequencies >50hz isnt effected as much as <30hz for room gain...so its not even talked about...
so if you want a speaker to dig lower you have to do 1 of 3 things
1)make it ported
2)make the enclosure enormous
3)reduce the efficiency
PSA chose a decent size box (enough to just not need stands) and high efficiency...since anyone who understands proper speaker placement and full range...knows you need a dedicated sub to take over for bass duties...cause proper spot for your speakers is almost never the correct spot for the subs...
