Wasn't sure where to post this. A home theater is currently being constructed [almost 18,000cf] which will be using 8 Ascendo 28" subs and two Ascendo 100" subs. All ear level speakers in the room will be the Ascendo Black Swans - I think 13 of them, and the LCRs will be the Black Swan...

I'm a calibrator by "hobby" [smiley face here]. ^^ What he said. And to emphasize my personal bias, "it's always the room"

The same is true of the Harbottle subs - and the Harbottle 18 has better specs [built in Canada]. They make the drivers and amps in house and the cabinets as well. An informed consumer is probably not the target audience for this company. That said, I do wish them well. More competition...

Something is amiss. Given their x-max of 29mm (using x-max vs 82%BL to more easily compare to other subs) their total displacement for two subs is about 6.7 liters of air. For about the same about of money ($60,000???), I can buy 4 Ascendo 18s + a 32" which displace about 27 liters of air...

Thank you. I have given active consideration to replacing my existing 10 foot Seymour screen with a 12.5 foot version. BUT, to properly light up a screen that size would require a new PJ [LOTS more lumens - and LOTS more money] AND a hush box. I am in year 13 on that screen and it is the...

Todd: When does that get published?

Thank you. That is very kind of you. It is a multi-use space: Music, Movies and because it is so quiet & peaceful, a great place to study Scripture. Thanks again. Chuck Gerlach

Interesting to see how well they survive long term . Their website shows an 18" sub with interesting specs. Their parent company, Swarm, does work for Triad, Klipsch and ..... Walmart among many other names I do not recognize. We shall see. If I were Ascendo, I would not be looking in my...

And that compares to the Ascendo 65 or 100 in what ways? Price?

Thanks. But how do I apply a specific filter type [e.g. Linkwitz Riley].

John: Thanks for your response but I guess I'm a bit confused. Someone who knows REW really well told me that I could display RdT directly. Is that not the case?

I did a search on RdT in this website but found nothing. This is the better measurement than RT60 for small rooms [according to many and as stated in the RP22 CEDIA document]. I've been told REW will display it but I can't seem to locate how/where. Thanks in advance.

I still don't understand how to see the effects of applying LR filters nor how to apply them.

I am aware that REW is not an equalizer. I am trying to simulate the results of using an LP/HP filter [specifically LR] to then be able to evaluate things like phase alignment, Group Delay, etc. I can use an iterative approach [various x-over, slope type, etc] using my Trinnov and then measure...
