Going on 200 years ago I commissioned this design from Rick.  I have finally spent a couple days in my shop and they are now 99% finished, just need to apply the baffle and rear panel gaskets and they are done-DONE!!!!!   With about 100 hours on them so far, I can say they sound very real.  I prefer them to my previous Selah Chalcedony design that Rick did, which was basically a combination of Tanzanite monitor and Whomp sub.  These speakers sound much more "live" to me which could be in large part to my room and the much higher-end amplification that I am now using.  I have gone through a few pairs of speakers in the past couple years and it's safe to say these are my favorites so far.  My previous SP Tech Timepiece 2.1's were great speakers and had an almost scary life like sound and 3d sound stage to them but they were not able to give the bass that I needed in my large room.  The new Selah's, with 4 10" drivers not only have deep bass to my liking  but they also integrate beautifully with the midrange and tweeter which cover harmonics dead-on.... specifically, the sound of the kick drum is right where it needs to be with the deep bass and the slapping sound on the skin of the drum that raises your hair.   WHile this design was in no way inexpensive I feel I got a heck of a speaker for the $.  Another winner from Rick.

Absolutely gorgeous!! 

How about some more closeups?

Very nice. What drivers are in the MTM module?

Seas Nextels & SS air-circ.

Those look very nice  I've been wondering about the
white & walnut contrast.

I know you're pleased..do this have the 'impact'/dynamics you've looking for?

Absolutely gorgeous. Overall sensitivity? Are the woofers active or passive?

Best,

One of my requests to Rick was that the woofers be passive.  They are being driven by Odyssey mono's with Symphonic Line amp on the mtm.  I was not concerned about sensitivity with my amps so Rick will have to answer this one.

I know you're pleased..do this have the 'impact'/dynamics you've looking for?

Yes.  I wanted a speaker that did not hurt my ears but did not put me to sleep and this design works well.  It is also designed as a somewhat modular system meaning the same enclosure shape can be used for center channel & rears.  I think it could also be adapted to work with just a active subwoofer using just the upper cabinets and a shorter version of the bass cabinet.   This is a very flexible design.

How about some more closeups?

Once I install the gaskets between the baffles and cabinet and remove the nice blue tape I'll snap some detailed pics.  I also need to install the coupling spikes under the top and bottom enclosures but my back is too sore from working on Marbles' subwoofers to lift these heavy things  right now

Nice work! I've been keeping an eye on your progress. Very interesting design. Please add more photos to your gallery when you get the time.

I wonder how different they are in sound to the Rc5g's,  seems to be similar in MTM on top, 2 x 10's on base cabinet.   Aside from the multiple cabinets, passive low end, I wonder if they would be very similar in their tone.

What would the cost of these be?

This is like a scaled-down version of the RC5 and similar in tonality. Chris can provide pricing for assembled pairs and he builds very nice cabinets.

I have about $3k into parts, including premium XO parts (Mundorf Silver/Gold) and all Groneberg TS internal wiring.  Cabinets, as I built them, with solid wood fronts and backs, would be around $2500 + lumber price (excluding hand rubbed finishes).  It's safe to figure $6k as a completed pair.  The cost of parts is pretty fixed other than giving up the good internal wire and stepping down in quality with crossover parts.  I commissioned this design about a year ago and the parts price has gone up almost 20% due to inflation   Any number of cabinet designs can be used for this speaker, which may influence the price a bit one way or another.  The design is not dependent on the curved cabinets, I just wanted something more sculptural than a veneered box.  There is quite a bit of lumber (no veneer) involved in the front and back baffles, approximately 30 bd.ft. of 4/4 walnut used on mine.  I have some Cocobolo burl lumber @ $45/bf.... aa 

As a side note, if I had a smaller room I would probably do two of the mtm's (ported) and pair them with two of Ricks active subs.

Rick,
I notice you use the same woofers as SP Tech... Do they get the same amount of movement (in and out) with heavy bass and is that normal?
Ed has brought some of your speakers to a NY Rave. Great sounding stuff!
Peace.

Someone can correct me if I'm wrong but Bob uses the Aluminum Seas drivers in a ported hybrid transmission line config. The drivers in this Selah design are in a sealed BR cabinet.  I also believe Bob uses an 8" driver in the Timepiece as well as the other models in his MR Series with exception to his newer Mini design.  Having owned a pair of his speakers and listened to his Revelation & Continuum speakers a few times I can say that the only thing in common between the two is the cone material and beautiful bass output, other than that they march to a completely different drummer.  The movement in the SP Tech woofers is almost scary, as you know, yet it's completely controlled and accurate but again this is in a ported TL cabinet.  Bob's forum is probably a better place to get an explanation on this.  The movement of the drivers in the TS3 bass cabinet and probably the RC5 as well, are very tight and punctual.  I have only heard the larger MR series designs in Bob's shop, never in my room but I owned a pair of TP 2.1's not long ago and used them in my big room.  I give the 2.1's a 10/10 for effort, but try as they may they could not fill my room with the bass I wanted.  They did do everything else to my liking as does this new speaker from Rick.

Yeah I was just wondering if they had the same kind of movement. But I guess that is a design choice. I believe the mini uses a 6.5" driver. Anyways I was just looking for movement comparison.
Thanks, btw!

I love the rounded edges and the 10" drivers must kick serious butt!

I will host a listening session with these TS3's and possibly other Selah speakers, this fall for anyone interested in the Chicago area.

I find it interesting that the TP couldn't produce enough bass for you, because I heard the nuforce s-9 in a large hotel convention room, and the bass it produced on Flight of the Cosmic Hippo was gut wrenching.  And that used 6.5" woofers without Bob's hybrid tline.  That was an eye opening experience for me.

I should have mentioned that I was running Odyssey Khartago amps with the TP's and as you probably know the TP's like their juice.  I really wish I could have heard the TP's with the new Symphonic Line amp I'm using .

The cone excursion isn't the same because the sealed box loading is different. If the enclosure size and / or tuning isn't correct with a TL or ported enclosure the woofer will behave that way. The Seas 8" tends to have lower sensitivity as well and a fairly high moving mass for its' motor structure. That's why I use two of them in my Peridot design and with the vented box the woofers don't unload like you observed in the SP speaker.
