I think a lot of us underestimate the costs involved going from an unfinished/unassembled diy kit to a real commercial product with all of the ancillary stuff involved(sales, support, shipping, etc, etc). JUST getting a cabinet, finished w/grill, to our fit-finish standards would cost us more than the "kit" price you linked.

So say 130+130 just for that. Assembly, QC, boxing, shipping, post sales support, Make it 110-120(per).

$380.

Now I'm not going to tell your new company what the bare minimum margins need to be to ensure sustainability(all monthly and annual costs of running a real business) but you could sell them at $450 each and end up like eD, Epik, Reaction, and who knows how many others.

@Tom Vodhanel since speaker discussion got brought up, I would like to share my perspective. Besides economics, one of the things that would prevent me from considering PSA speakers upgrade is the height of the Center Channel. 11" is just a little too much for me. I could make 9" work, but 8" max is where I would like to be. Based off what I have read, I am really curious about your 110s and 210s but would have to completely change my front stage and/or viewing angle to make them work. Other speaker brands I have read about or auditioned at local retailers feel like it would be more of a lateral move than an upgrade to what I currently have.

Check it out here if you are so inclined. Skip to the last few pages for some more recent reviews.
I’m a week behind on this thread. I built 2 of these boss platforms and if I’d have done this a couple years ago it would have saved me many thousands of dollars. You could get a sub that reaches down to the high teens and add this platform and have all of the ULF and tactile feedback you can handle.

When is someone going to start making these available to order? Some of us don't have the tools/time or the skill to make one. Would love to experience this to see what its like.

Very DIY stuff Tom

The appeal of this is due to the low cost and involves very custom application based on ones seating. Shipping large plywood pieces is not economical either.

How much would you be willing to pay? @imureh is right, its really just crazy easy and cheap for TR as diy. Selling it would be comparable to a starter Crowson kit by the time your done. Seating and fitting has its challenges with it as well so making a "fits all" would prove futile as seat to seat variation seems to be all over the place as Ive followed. A few are bolting drivers to their chair.

It is pretty awesome though for the price.

I'm likely going to run a phantom centre even when I upgrade my setup. I listen to music a lot more often than I watch movies anyway. Try that with your current setup and see how it sounds? If you're usually the only one watching a movie, or maybe just one more person, you don't need as wide of a sweet spot for the centre content. I've watched a movie with my 2.1 and didn't miss not having a centre.

With that being said, I rarely watch movies so maybe a centre is more important than I think, even for just one listener.

Yeah I'm glad I have the Crowsons because I'm not sure I could make a BOSS work in my room with the way my seating is. It looks cool and I would love to play around with one but for various reasons I think this would be a no go for me. Either way, it doesn't matter since I have the Crowsons... but it really is a great idea and an incredibly affordable way to add ULF tactile response.

I'm sure there's some decent options for you guys in the UK at the $1000-1500 price point for 5/7 already. But, like any region you'll have to balance sound quality with aesthetics. I probably steer people to the asecnd 170s 20x a week. But 19x a week they tell me "meh, too big and ugly. I'm going with these little cool orbs that are glossy and won the prestigious "best of cookie cutter website" award. Sigh

Then again I'm the guy who would rather enjoy a *good* film thru built in tv speakers than sit through the fast and the furriest on a 7.7.7 whatever system so who am I to judge..

Take a glance thru soundstage and stereophile. Then read thru any posts here made by Dr. Toole. You'll have a good idea of the overall sound of the speaker just by looking at a few key measurements. After that, just start making a short list of the models available near you in the target budget.

Tom V.

When I'm ready to upgrade, my budget will (hopefully) be more than that for the fronts alone. I just felt that the cost of a 5/7-speaker system with the current lineup cannot be justified as I rarely watch movies. So the idea that I'm currently fantasizing about is as follows:

MTM-210T's for the FL and FR, run a phantom centre for movies, and see how my Monitor Audios sound as the surrounds with the PSA fronts. If I find that I'm happy with the integration, it would save me from spending on something like the 110SR's.

With the regards to the sub(s), I like the idea of Rythmik F18 or sealed PSA. Any plans of neo sealed at some point?

As far as I can tell, what they are calling a boss platform is just a short riser with isolators between it and the floor, and a few speakers mounted on it using the cone and coil mass to vibrate it. I don't get the point, wouldn't it be more effective using actual homemade bass shakers, not regular speakers that still have the cones?

I have 2 JTR S2 subs up against my couch and 4 B1200 midbass modules. My BOSS platform with 3 $29 JBL drivers provides considerably more tactile feedback than those speakers. Had I found these before there would really be no need for the S2’s behind my couch. Could have saved some $$$ 😀

It is great for people on cement floors.

Given the low cost of entry, I put together a BOSS platform for less than $100 and the hype is well justified. I was very skeptical, but the effect is very natural and blends well with the subs. I've never experienced Crowsons, but I would take this over any of the other shakers I have experienced.

I'm using 1 channel of an old Onkyo AVR to drive 2 of the JBLs in series. Since they are in free air, it takes very little power.

Hey Ray, I agree with the other poster that there's too much of a gap in your bed speakers between front stage and the rear back wall mounted SR110s running a 5.xx system. I would have no problem mounting the side SRs in between the front and back row seating on the green outlined areas in your photo and designating them side surrounds and rear wall mounted as "back" for a 7.xx configuration. The side speakers will be slightly behind the first row and in front of the second which will give you that immersive enveloping integration with your LCRs..

Don't get me wrong, not saying the boss platform is bad, just that I don't get why it goes halfway there and leaves the speakers as speakers. They'd probably be much more effective turned into shakers.

They do work as shakers in a sense. They shake/move the whole plywood platform which sits on very soft isolators (half round sorbothane pieces)

There are several in that thread that have crowsons and prefer the effect of the boss platform. In fact one is going to sell his crowsons.

Right, I'm saying why not remove the cones and make it a real shaker like this
- instead of using a regular speaker as a 'shaker,' with only the voice coil/former and cone as mass. Maybe I'll experiment with one, you could probably get a similar effect as the current platforms but with a single 8" driver. I think the isolation from the floor is the important part of the platform, there are better ways to make it shake

So I would do an lfe out of my Marantz to my old Onkyo receiver (not sure which input) then have a l/c/r channels going to three of the jbls with regular speaker wire. It is an 80 watt per channel receiver

The BOSS sounds interesting, but my theater space is also the living room so risers would look out of place. I'm also on concrete slab. I just discovered I still have my old JBL SUB-12 with a burnt out amp sitting in a closet. I wonder if I could take out the driver, mount it on a small piece of plywood and then attach the plywood horizontally to the bottom of the couch frame. The vibration of the driver should transmit directly to the couch frame via the plywood, correct? Wouldn't have the impact of three drivers, so I wonder how much vibration you would actually get.

Due to the way that it is set up in the physics involved, it would give you a lot more tactile response then running a nearfield sub unless you had multiple. I’m going to be building one for my downstairs room on concrete which is just my extra room. It would not look right upstairs in my main room. Plus my main room upstairs is on a suspended floor and four ipal 18s should take care of business :-)

Both the "boss" and nearfield subs provide TR but in difference sense. The "boss" is geared more towards ULF 35hz and below for the wobble effect only while the very nearfield is more for chest slam 45hz and up.

I have both crowsons , not "boss", for ULF and very nearfield sub right behind my back for the midbass. Being on concrete flooring its nice to get the whole thing reference down to 5hz. You being on suspended flooring you probably don't need the "boss" or shakers at all....but it will get you reference at single digits that subs can't do...even the ipals.

Since you have 2 rooms....its nice to have that comparison to have boss setup on concrete and regular subs on suspended floor.....interesting to see what you think of the difference once its setup and dialed in.

Adding one sub for Boss setup will be noticeable....but of course more drivers will shake more. The reason you see others with at least 3 subs is because jbl drivers are so cheap so they buy more. Oh...and because they are NUTS!
