Danny, if you would come up with that type of design I would be all over it. I want to build something good that will work in this #*!!! room of mine.

Are you interested in a single woofer in a transmission line or a MTM in a sealed box?

Man. Gotta love the different options Danny's about to put out there. Going to look under the sofa cushions for some more coin! Would love to get into one of the new NEO 10 designs.

Yes, after hearing what the neo3 tweeter can do, I am severely interested in the Neo 10 and this new mid driver in a next gen design.

Danny, I thought you were talking about a MTM in a TL so apparently I need some advice. I have a very large room that's about 22' X 37' with a 17.5' flat ceiling.
This room is tile and a lot of glass and the kicker is I can't get my speakers more than a couple of feet from the front wall as the end of my couches are in front of the speakers.
So, I need the speakers to be tall enough so they aren't looking straight at the end of the couches (which are very low profile). I'm also wanting to move to a small tube amp so I would like them to
be efficient. The problem I have with my current rear ported Ariel 7Bs is the metal dome tweeter is painful and I don't get near enough bass. They have (2) 6.5" woofers and I had to put them on
additional stands to get the bass out of them.

The Qts of the 16 ohm woofers is pretty high for use in open baffle applications. So an optimal ported or transmission line cabinet would get pretty large for a pair of those drivers.

I was thinking of them in a sealed cabinet and using a servo sub for the bottom end.

How about an MTM design in a sealed box with a side loaded 12" servo sub in the same cabinet?

Now that is something I would be interested in since I don't have room for open baffle. Sort of a N3s mounted on top of servo sub with all of the crossover figured out by you.

This sounds like a good solution! Could you give an idea of dimensions needed and would this be a one box solution? And what speakers are you thinking of for the MTM?

I am thinking of about an 8.5" wide tower with the servo sub on the side. And an MTM with my new woofers.

Then the Peerless tweeter (top level dome tweeter) in a wave guide.

Danny, just curious, what is choice made when going between a wave guided dome and a neo tweeter?

Each has its advantages. More on that later...

O.K. I'm in, this is better than I had hoped! Now when are you going to get started?

I get started as soon as I have all of the drivers here.

Danny,

What is the narrowest width of a open baffle for the new 8" Servo drivers?

Thanks,
Robert

I wouldn't go any less than 9.5", and then I'd add some type of a vertical support/side wing.

Danny, I'm looking to make sub cabinet/stands for monitors. I want them to be about 10" wide and 24" tall. Seems like two of the 8" servo subs per (sealed) box would be about perfect.
Any idea when you expect the drivers/amps?
Will the amps have any high pass filters built in?

I have the 8's in stock. Brian also has lower Q 4 ohm and 8 ohm 8's in stock. The A370 amps can be used but Brian is still waiting for the new smaller amps that were designed for these woofer. I wish the new amps were here already.... When the new amps are here then we will really advertise the combo.

Marbles · « **Reply #176 on:** 12 Sep 2012, 02:03 pm »

The PQ370 has a low pass filter, will the new amps have a high pass as well?

No, no high pass filter. And many plate amps do add a high pass filter to the speaker level outs, but don't use it. It is just a cheap electrolytic cap placed in the signal path. You don't ever want that in the signal path.

We could add a high quality high pass filter in the RCA outs, but the cost of doing so with quality parts would be too expensive. I typically select a small value Sonicap Platinum to use in an in line RCA to roll off the bottom end of various speakers. That cost about $100 in parts to do that. And that is at a fixed value.

Marbles · « **Reply #178 on:** 12 Sep 2012, 02:43 pm »

Thanks Danny, but I do ~~need~~ want speaker level due to the simple receiver setup I have.
Maybe I'll build a high quality passive XO that full ranges the sub and high passes to the monitor. The sub amp has a built in 80hz low pass on the speaker levels, right?

rockdrummer · « **Reply #179 on:** 12 Sep 2012, 04:07 pm »

In reference to the inline RCA high pass filter, where does the signal need to be split to get to the subs? I'm trying to figure this out to see if I can use it with my 2 channel plans.

Embarassingly clueless.
