Axiom Home Page Forums General Discussion Home Theater New to 5.1

Hi everyone. I have just recently started to upgrade to a "modern" HT setup. I am buying a system that will be easy to move into a larger room when we move to a new house. My first purchases were:

Denon 2805
Axiom M22 (Replaced by M60/80 in larger room?)
Axiom QS8 (2 now, maybe 2 more for 7.1 later)
Axiom VP150
Axiom EP350 (BTW, got all at the Outlet Store. Great price!)

I have 2 questions:

1) In "blending" the fronts/sub, is a 60Hz crossover point acceptable? I would rather not have the sub voicing over that point, but I also don't want to lose sound and/or have the M22ti's fluttering. This especially concerns me regarding stereo audio-only playback, although this won't be my main audio setup.

2)Has anyone out there heard of a now-defunct speaker Mfg. named ADS? I have a pair of their 2-ways my dad bought in 1975. They are beautiful sounding speakers. I was wondering is there might be another owner who might have some thoughts on these speaks.

Thank you,

Mark

As for #1, I'd probably start with 80 Hz for the M22s, but if it works for you... Try doing some frequency sweeps if you've got a SPL meter. If not, get one!

On #2, I'm totally useless, as opposed to mostly useless on my #1.

Welcome to the boards, btw. Have you received teh speakers yet?

Welcome, Mark. A 60Hz crossover for the M22s would certainly be "acceptable" in that they have fairly strong response at that frequency, but the commonly suggested 80Hz should be a bit better. The EP350 should handle that range with more authority than the M22s possess and would relieve them and the amps in the 2805 of a little more of the low frequency burden.

No, I haven't received the speakers yet. Because I picked everything out of the Outlet Store, I have a few weeks wait. After spending 3 months researching the speaks and AVR, I'm spending the wait period further researching setup and functionality. My old setup is a mishmash of speakers plugged into an old H/K Dolby Pro Logic receiver. I finally decided that I would like my movies to sound the way they were meant to sound.

As far as the ADS speakers, I haven't seen a whole lot about them. I use them as the only speakers on my audio-only setup I power them with a pair of tube amps by dad and I (mostly dad, I was 7)built the same year he bought the speaks. The sound is unbelievable. I run the components through an ancient Onkyo preamp. I swear you can hear if the rosin on a violin bow was unevenly applied.

You're in for a real treat, then.

I suggest getting a Radio Shack SPL meter (analog) and a AV tuneup disk (AVIA, Home Theatre Essentials). Of course, if you've lurked here for, oh, say, a day, then you've heard that before.

I have read that 80Hz is a good point. Being new to subs in the HT context (I used to do live sound mixing) I am just worried about the clarity of the sound between 60 and 80Hz. At the clubs/halls I used to mix at, this was not such a problem due to the enormous power and sheer volume of air being pushed by the generally overpowered systems. Especially since we generally had 3 and 4-way systems (2.1 and 3.1, I suppose!)so all frequencies were send through outboard crossovers with very specifically set pass points. For HT/Audio, I will be a little more sensitive to such things.

The meter and disc are on their way. I have seen these 2 pieces ALL OVER the internet! BTW, I apologize for the occasional misspellings. I need to actually preview my posts a little to make up for my sloppy typing.

Don't worry about it. Typos tend to slide around here, unless they're egregious. In which case you'll be made fun of, lightly.

BTW, the company that made my audio-only speakers was ADS Speaker Lab, not the ADS that is currently making speakers. There is no relation between the two.

I think the only concern about crossing M22s over at 60 hz is that you're probably going to get a slight dip in the 60-70 hz range since the M22s are already -3dB at 60 hz.
