While this might seem a little cumbersome vs a fully passive version, realize we can offer 4-10dB greater sensitivity over ~70% of the speaker's operating range with this solution, while maintaining the very compact size of the Spark.  This single channel version of the Spark XC1 will sell for $795 each.  Appropriately powered, pro audio amplifiers with integrated DSP can be had for as little as $200-500 per channel, or our optimal solution will be $700-800 per speaker.  Over the course of the next year we will be developing amplifiers with greater channel density and more DSP channels per chassis, which is the limitation at the moment.  This version will be designated XC1 indicating the single channel amplification.

Does the placement of this statement, "Over the course of the next year we will be developing amplifiers with greater channel density and more DSP channels per chassis, which is the limitation at the moment." in the Spark XC1 section indicate that these new amps are only intended for the XC1, and not for the XC2?

Previously you had mentioned hoping to come out with a single amplifier to power four of what you're now calling Spark XC2 in a single chassis.  Is that still in the works?


Same basic amplifier.  Our amplifiers with DSP can be configured for most any usage given we have enough inputs.  Once we have a new DSP developed with more inputs/outputs and the density to fit all the connectors on the back of the chassis we can allow for 4-8 speakers to be powered from a single chassis.  The tweeter and woofer use the same 300W ICEpower module, but I err toward reality in rating it at a real 200W into the HF load it's driving rather than the 300W label on the amplifier. [wink]

For anyone wiring up for surrounds now, I recommend running 4 conductor wire to each speaker so you have either option of bi-amp or single channel operation now or in the future.

I have a quick question. I need four sparks for atmos duty and XC 2 option means I get two amps. Is there any way you could offer an amp that can power all four channels. This will be an issue of finding enough rack space to house multiple amps.

Cheers

That's what I just asked about.  Mark's working on it.

Just realized that. I will try and wait for it.

I do have some pro-audio solutions which can work now rather than waiting, but that assumes that fan noise isn't an issue, and I believe those solutions might increase the cost slightly.  If fan noise isn't a problem we can also do very reasonable cost 4 ch amplification for the XC1 versions and these can always be changed to XC2 operation.  I'm working on the circuit board design to possibly allow the XC1s to easily be configured for bi-amp mode by just moving 4 jumpers/connections.

Can regular no fan amp be used? Like Parasound a51 or one of the emotiva amp?

Our SSA-2x2 has no internal fans and makes no noise in the room.  This amplifier uses 4 of ICEpower's latest amplifier blocks with the same DSP as used in all Catalyst models.

At this time equalization is required, so a traditional amplifier like those from Parasound or Emotiva amplifier would also need an appropriate equalizer in front of it.  Audyssey alone won't do the trick, but a manual/full Dirac EQ just might.  We'll keep experimenting with various options, and there is certainly more to come.

Dear Mark,

Please tell me -- what are the specifications of the F 4?

What is the status of the F4?

Thank you.

Best wishes,

Hi Mark,

Some more questions for you. [biggrin]

Can the production bracket be also used to mount the speakers to the ceiling? Secondly, will the magnetic grills stay on when the speakers are mounted to the ceiling and facing towards the floor (they won't come off or fall off, right?)?

Good question.  In the thread about the new F18 there are also pictures of how the 6 Spark XC1's were used in the theater.  Mind you the guys who hung these speakers install huge arrays of speakers overhead in large churches and similar performance spaces.  We will have a custom bracket which keeps the bracket & speaker tighter to the wall for different mountings, but you can see these were all mounted to the ceiling, largely because the off-the-shelf Allen U-Brackets are a little longer than is needed.  Either mounting works great as you have a large 5/16" bolt through the metal bracket into a large bodied, threaded insert.  The aiming angle is easily locked in place by tightening the 2 side bolts.

The magnetic grills use the same very strong magnets from the SubMersive & Catalyst even though the grills are much smaller, and the magnets are tighter together.  The grills take a good pull to get off and stay in place much better than many peg mount and metal screens from in-wall/ceiling speakers I've worked with.  The grills snap in place very well and I have no worry about the grills coming off unless you deliberately do so! 

Here is an overall shot of the rear of the room they were first installed in:

Here are some closer shots of how the speakers were mounted:

Mark, so are you saying a traditional amplifier along with a MiniDSP 2x2 solution could work?  I.e., since upgrading to Catalyst 8C's upfront, I have a 7 channel 200w Sunfire amp sitting around that would otherwise be powering whatever dual surrounds/rears I end up getting (due to room limitations will just end up with 2 speakers, unfortunately behind the main LP vs at the sides).

Happen to also have a MiniDSP lying around and would love to utilize them if I could with the passive Sparks, but I didn't think you'd be handing out the DSP settings!  So maybe misunderstood the comment!

Also, are there any ideas about wall mounts that are as "flush" to the wall as possible?  I love the 5.5" depth of the speakers and wouldn't want it protruding much more than that if possible.

...coincidentally I will be in Chicago in mid-late August, though I don't think I could stuff two of them into my carry-on! [smile]

Hi pbc,

You are correct that we can use a MiniDSP 8x8 (10x10), or 2x4 unit (used for 2 speakers each).  For the Spark XC1 version I have no problem sending DSP configurations.  I would prefer to do the filter verification here vs. just entering values, but I can make that happen.  The XC1 has a crossover that blends the drivers but requires some EQ to fully smooth the response to our desired performance.  

The U-bracket will be very close to the wall with a 6" cabinet depth being the target when aimed straight forward.  Depending on the elevation and if you are using Atmos overhead speakers, also consider putting them at the wall/ceiling junction where they can tuck in very tightly placed in the wide/landscape orientation due to the tapered rear profile of the cabinet.

E-mail us and let us know when you are coming in town.

Mark - left a few emails and a vm a while back, would love to take a couple of the black oak XC1's off your hands if available yet? [smile]

The only difference between the XC1 and XC2 is that the XC2 is bi-amplified while the XC1 is not (i.e. single channel)?

Hi guys,

We're not quite there yet, but we are very close with the Spark XC1 which will be fully passive to use with any common amplifier or receiver.  This took making some more space in the box to actually fit the crossover and a good deal of development, but we're just about there.  The sealed and compact box won't be a screamer in efficiency, but can handle >500W with ease.  Pricing will be under $900 each.

Would you be able to paint these white, so they would fit in with my decor better. And also the brackets?

Yes, that is possible.  Matching whites can be a real trick as even the same color paint on different surfaces or textures can look different.  I'll be looking into this after we have things sorted in producing the black version.

Any update on these? Could they be used all around in a 7.2 setting, with at least 2 subs?

We ran into issues with the CNC cutting when we went to run the first batch and are making some aesthetic design changes to insure we can produce them reliably.  Dimensions will remain the same.  We'll very soon have both the Spark XC & XB models re-sampled so we can finalize the passive crossover designs.  These can certainly be used as mains as well as surround applications.  When space allows I would recommend the XB version which will be a 30" tall model with 2 8" passive radiators to relieve the bass load from the driver and provide greater sensitivity to the low end of the speaker.

I'm working with a target of having these models available very soon after Axpona (April 15-17th).

this June (2016) it will be three years since i've been waiting to buy these.  I wonder how many more years i have to wait? [smile]  I can see why some choose to sell off their amazing Cats speaker.  Mark, I really hope you will have these ready by June.  Three years is way to long to wait for matching surround speaker!

The Axpona show next month will be one year since I posted the sneak peek of these. I could go into all the reasons the spark did not go to production in August and September as planned. They end up just being excuses. In the end our cabinet shop could not produce he planned cabinet design a livel he planned cabinet design reliably. I have redesigned the cabinet, and we had to sort out some finishing issues with one of the design elements. We will have three Spark family versions on display at Axpona, 2 on wall/ceiling mountable along with a floor standing unit. We will begin taking orders on all 3 models at that time, not sooner.

Later this summer we will be introducing a smaller in-wall and in-ceiling solution as well.

I think this question has already been answered previously but I would just like to confirm it. Does the amplifier that mates with the new Sparks have any internal fans or is it passively cooled?

Edit: Should have just re-read the first post in this thread like I just did. No fans. [tongue]
