I figured it was time to start a thread dedicated to just the Ascend Towers. They have yet to be given a formal name, and once they do, we can update the thread title to reflect the change.

The towers will be coming soon and I hope to have the first pair

Dave just posted a few pics of the prototypes he plans to demo this saturday. More info can be found in the Tower thread over at the ascend forum.
http://forum.ascendacoustics.com/showthread.php?t=4392

Preliminary data:
MTWW design
Mid - proprietary 5.25" (roughly) with gold phase plug. Could also be a bit larger, closer to 6.5"....unsure as of now. Pics look deceiving.
Tweeter - Seas Proprietary Nrt (neo ring tweet) 29mm dome. -3dB at 28kHz (taken from sierra-1 Nrt measurement)
2 Woofers - similar driver found in the sierra-1(custom / proprietary) but tweaked for use in a larger enclosure
Rear ported - port plugs from sierra-1 will work and help accomodate placement options
Size - 7.5" wide, 43" high, 10.5" deep (based on pre-production models)
Cabinet construction - Bamboo, same VLAM construction as Sierra-1. Finish options are still TBD but a High gloss black (very similar to the current Piano black) will be offered.


More info to follow.

Patrick,

Of course Pus, I have always wanted to start an "official thread" following in the footsteps of Brandon (nuance)

farmingdad 11-16-2010 09:12 AM

Thanks for the thread start, these are going to be fun speakers to follow. I can't wait for a listen! Now we need to get on Dave about making a planar or open baffle

cschang 11-16-2010 09:51 AM

If anyone wants a listen, we are having a listening session this Saturday at Ascend to hear the pair in the pictures.

i need some education. what's with the golden nipple in the top driver? i've seen these on some speakers and wondered what they were.

Brandon,

Those are big shoes to fill but I'm sure you are up to the task. I look forward to more information on the Ascend Tower. I hope you are one of the first owners as you have been patiently waiting. I wonder if the Tower will come in a Dark Cherry finish as I still have my Sierra center. You never know and I want to be prepared.

Bill

It's a phase plug.

Here's a good explanation:
http://www.preference-audio.com/phaseplug.htm

There are some drivers that use a "fake" phase plug where the plug is part of the speaker cone and moves with it. A "real" phase plug is part of the pole and doesn't move.

thanks for the link. so the top driver is the midrange and the two bottom drivers are woofers? i was wondering because they appear to be the same size and i thought the woofers were typically larger than the midrange.

Actually, in this case, the midrange is a bit larger than the woofer.

While size does play a part, it is the overall design of the driver that dictates its usage.

Grandarf 11-16-2010 03:33 PM

Any specs and measurements yet?

First I think they look horrible post... They must sound awful... And with the stained bamboo (they will be bamboo?), who would want to get a pair of those? Not me... Well... Kinda... Get out of my head you... you... towers you!!!

Nah, I'm ok, really, the NrT upgrade should be more then adequate for me!

(if not obvious, this post was sarcastic, I think they look great. Also that's not the final finish & does not represent the quality of the final design and yada yada)

Bill,
I have been very patient and waiting very long as you know. I believe I will be the first owner. Dave has been very gracious and has answered all my questions and concerns over the last year or so while his design went from an idea to final product. I am glad I chose to wait, the towers sounds promising...pun intended As for finishes, I believe Dave is contemplating several options, I believe the more he offers, the higher the costs. If anything, maybe folks who want a different finish option can just pay the difference over the "standard" finish. You might be glad you kept your sierra center who knows, we might see those Song towers on audiogon soon

Check back after this Saturday, Dave is hosting another listening session and I imagine the black pair shown above will sound even better than the prototype did several months back(due to numerous tweaks).

Later,
Brandon

Brandon,

I think you first nudged me over 2 years ago with regard to this speaker .

It has indeed been a long time coming and we are not quite there just yet.almost. Sadly, the fun part (for me at least) is over and design/engineering work is now replaced with manufacturing and logistics.

Yes -- you will indeed have the very first pair and if not for your weekly emails, this exciting new loudspeaker would not exist.

Thanks for your continual encouragement and when you finally do get the speakers, I hope you absolutely LOVE them.

Any ballpark on price, or ballpark on time frame for price announcement?

Are the cabinets still bamboo?

Grandarf 11-17-2010 04:57 PM

Good info by Dave:

any particular reason why the tweeter is between the mids and the woofers and not on top like most usually seen? MTWW vs TMWW? Curtis earlier mentioned it might have to do with OPPIX, but does it really use OPPIX and if so, does orientation of TM really make a difference?

Excellent question!

There are a few reasons for this orientation.

First off, it was important for us to keep the acoustic center of the critical tweeter and mid combination as close to the lower woofers as possible. This type of orientation allows for tighter phase integration between all of the drivers and is closer to acting like a single point source as compared to the more common TMWW. In addition, for most listeners, the acoustic center will be at or very close to ear level.

Another key aspect is that the midrange driver is housed in its own critically damped sealed enclosure, the volume and damping of which is carefully controlled to obtain a specific acoustic rolloff and Q. Assuming the same dimensions for the cabinet, in a TMWW design, if the midrange driver was to have the exact same enclosure volume, it would take up some of the cabinet volume the woofers would require thus we would either have to make the cabinet taller or settle for slightly less bass extension.

And finally, this orientation provides more vertical directivity and a more symmetrical vertical off-axis response than a TMWW design, thus reducing ceiling and floor reflections, but with a considerably wider vertical listening window compared to an MTM design. An MTM design will have greater vertical directivity but will also exhibit off-axis lobing, which is not consistent with mimicking the response of a single point source. The MTWW design was the perfect solution and retains much of the off-axis characteristics of the Sierra-1, thus keeping the speaker in the same family

The imaging of this speaker is remarkable yet it is not at all fussy about placement.

Hope this makes sense!

So sealed mid is interesting, as well as the inverted tweeter which we've started to see from a few companies like Vienna or PSB, good stuff!

Forecast is for rain on Saturday! Good time to listen to these towers and NrT at the Ascend offices! 10:30am!

Sorry 'bout that.

Yes -- while the prototype we are currently demoing is not bamboo, production versions of the tower will indeed be bamboo.

Any more pics/impressions of the towers after todays listening session?

Still sound great. If there were any changes, the bass sounded better, more coherent/integrated.

I took a few pictures with my phone....but nothing spectacular:

skeeter99 11-20-2010 11:13 PM

Cool thanks Curtis! I love the phase plug on the mid, looks very trick ....

Bill Mac 11-21-2010 11:52 AM

Curtis,

Were there any other speakers that the group compared the Towers with?

We had previously compared them to Songtowers. We didn't have time to do that this time around... i suspect that is because there wasn't much interest in doing so.

How did the Towers compare to the SongTowers?

Curtis..... is that the crossover laying on the ground behind the speaker there...

Bamboo towers - that should be a nice inert cabinet....
Any sketchups of the full tower in bamboo in the various colors...?

I'm curious, is it possible that the speakers may measure a bit different and still need some tweaking to the crossovers when drivers are finally placed in a more dense/inert bamboo cab...

Also, have you sketched up a design for a matching center with dedicated mids or 3 way design...
What type of alignment would be used if so.....

Things are looking nicely there David.... Keep up the good fight... !!!

Tarpon 11-21-2010 03:45 PM

How is the bass extension in comparison to the Sierra 1 and the Sierra 1nrt?
