Patience is an absolute requirement around here     But, the wait is worthwhile if you are interested in a specific design.  It just has to bubble up to the top of Danny's priority list over time.  

[Danny Richie]

Do you have a cut list and/or dimension layout for the LS6 and LS9 yet?

No, but I might have something by the end of the week.

Guys if it was all in my hands, you wouldn't have to wait long. Unfortunately custom driver development involves other companies and I have to deal with their time frames.

The woofers for the open baffle line source won't be to much of a problem though now that they have figured out XBL^.

[arthurs]

Danny, hopefully you know we totally understand the time required for development, and that critical components are influenced by others, nuff said.  The "kid before christmas" impatience aspect of this is our own doing, and I for one am ashamed of myself for not being more patient...          

Have a great day everyone!

How far should the back of the open baffle and line array speakers be from the front wall?

[Hank]

I for one am ashamed of myself for not being more patient...

Oh yes, me too.  Yes, I am totally ashamed.  

Seriously, I understand the back-and-forth with the Asian driver manufacturers, particularly with the third party designer involved.
Hey, good things take time.

Danny R - Edp here, missed seeing you at CES.

Question on the new drivers.  Will these XBL types be available as raw units as all your other M series?  Do you plan on keeping the 16 ohm model also?

Hope all else is well with you, your family, business and Mr Dodd.

Danny R - Edp here, missed seeing you at CES.

Thanks Ed, I have a lot going on right now and a lot of design work in progress so I really didn't need to take off.

Plus, I am sure that from now on I will have to be there exhibited or assisting one of several clients that I am now working with to exhibit.

This was my last chance to take a break from going to Vegas, so I took the break.

Question on the new drivers. Will these XBL types be available as raw units as all your other M series? Do you plan on keeping the 16 ohm model also?

They will be available as raw drivers, they will be reasonably priced as always and there will be a 16 ohm version too.

Hope all else is well with you, your family, business and Mr Dodd.

Thanks, business is good, family is good, and goof friend Gary Dodd has big things brewing too. This is going to be a very fun and interesting year.  

[wshuff]

and goof friend Gary Dodd has big things brewing too.

A telling slip of the fingers, maybe?  

[Danny Richie]

Yea, may good friend Gary Dodd is now a goof.  

Okay the "F" is right next to the "D" on the keyboard, so I wasn't too far off.

[wshuff]

I imagine that most of my good friends would make the same mistake when referring to me.  That's probably why they put the "D" and "F" so close together.

Looking forward to what you put together.

I've been wanting to buy Danny a Spell-Check program for a couple of years now.     Question is:  would he have time to use it?  Nah.

Just a few questions concerning the Line Arrays.

Both the LS-6 and LS-9 should -3db in the mid 20's.

Does that include any room gain?

I really like the idea of numerous speakers supplying the bass.  My youngest is playing the drums now, and the difference in a live drum kit and what most speakers reproduce is significant.  If you really do get the feel of the bass drum, that would be impressive.

What would you consider the absolute minimum distance between the speaker to the listening position?

The reason I ask, is that the two times I have listened to the Alphas, the distance between the speakers and the listening position did not seem to be more than 10 to 12 feet.

Also, with the new arrays, how far from the wall would you place them?

Thanks,

[Danny Richie]

Does that include any room gain?

No, it does not.

What would you consider the absolute minimum distance between the speaker to the listening position?

I would recommend at least 10 to 12 feet range on the LS-6 (the shorter array).

Also, with the new arrays, how far from the wall would you place them?

This really depends on the room size.

[jacket_fan]

Does that include any room gain?  


No, it does not.

Very intriguing.

What would you consider the absolute minimum distance between the speaker to the listening position?

The reason I ask, is that I am 50/50 music to HT.  I added a second row of seats which moved the sweet spot a foot closer to the speakers.  It leaves right at 11 feet from the speaker to the sweet spot.   Distance between the speakers is 9 feet.  The room is approximately 20 feet from the front wall to back wall.  

Kinda disappointing that my room is too small for the LS-9s.  It has been awhile since I read the line array white paper, but I thought that the line arrays were not sensitive to seating distance.

[Danny Richie]

You can get by with them in a smaller room if you treat the room pretty heavy with room treatment.

[EProvenzano]

Danny,

What are the detriments of a smaller room for the LS9?
My room is 14x19 and what I gather from this thread is that it is border-line too small for the LS9.

I am intrigued by the LS6 but in theory the LS9 should operate more like a true line source and I don't want to forgo any of those benefits if possible.

The room is dedicated to 2 channel audio, so treatments won't be a problem. What room treatments to you recommend?

Your thoughts appreciated.
Best regards,
EP

[playntheblues]

Hi Danny, same question as "EProvenzano".  As you know I have been waiting on your new line arrays as well and my room is 25' X 15'.  The only difference is that I will have an additional 4' behind the speakers so the effective room size will be 29' X 15'.  Thanks Guy

[Danny Richie]

Eric, if the room is too small you will have a harder time getting away from room loading in the low end. You might have this problem some with those Alon's. I guess the good part about the Alon's is that you can turn down the gain to the sub towers as needed to balance with the mains.

Also, by the length of the array you need to be an adequate distance from them to not be too close into the near field. I think you'll be right at my recommended minimum but okay.

My buddy Gary Dodd shoe horned a pair of Alpha LS's into his 12' by 13' room. With a lot of room treatment and by dialing down the bottom end with the bass management system it worked out great.

When we tried a pair of Epiphany 20/21's in his room he had the problem of being too close up into the near field.

Eric, you could squeeze in a pair of LS-9's but you would need to treat the room on the heavy side.

Here are some links to some good room treatment DIY sites:

playntheblues, your room is deep enough that I don't think you'll have a problem.

[arthurs]

I often wonder if my room is big enough for LS-9's.......maybe something larger......???????

           

[EProvenzano]

Eric, if the room is too small you will have a harder time getting away from room loading in the low end....

Thank you Danny.
You're the third person that's called me Eric in the last while...Do I have a note pinned on my back???

I guess that's easier to remember than Emilio....no worries though

Will the LS9 incorporate a bass management system?
What are your thoughts on 'tapering' the xo for your LS designs?

TIA,
