How big is the room? What's the distance from the listening postion to the speakers? How loud do you want the system to play?

Is doubling up the mid range and using 4RS180 really that noticeable in sound? or other? When listening to these or others mentioned will there be that much of a difference. Or hardly noticeable.
TIA

Have we exchanged emails yet? I'm just wondering because if that is the case I won't repeat myself here.

A quad of RS180s will give you more dynamic headroom and a ton of power handling. The RS180s wired in series parallel have a net 8 ohms impedance, which is easier to drive. If you want fewer woofers, that's why I have the 2T/2cc version. They are sonically similar to the rest of the Dynamic series, just will not play quite as loud. The array of woofers spreads the floor bounce/ceiling bounce reflections over a larger range so the FR is flatter etc in the mid/bass. Dual mids are cleaner than a system with a single midrange (in general), because there will be less harmonic distortion. The dome tweeter allows a lower crossover point to mitigate comb filtering issues/power response issues.

People on this forum with published designs really need to update their BOMs to reflect current pricing because all the Dayton drivers/TB have gone up in price. My pricing is retail of the parts.

Well, I could go on, but you might send me an email and I can forward more info to you.

Regards,

Jed

The room is 22x20, Listening position is approx 16' for HT, for music well always moving around...
Although I can easily play to 110-115db, the goal is more for realistic clear sound.

Wow, that's loud.

Maybe you could convince Jed to design you a M5 (MTM) with a pair of woofers, RS270's or RS225's, or a quartet of RS180's. I think the SB15 has the best potential (as I haven't heard it) of sounding the best.

I'd do a 4T, sealed and HPs at 80hz with a pair of IB subs. A ported 4T will get you close to the 110db estimate, but will quickly run out of power handling below 30hz, just like any ported box would. In that case, use a subwoofer to handle the lower frequencies.

Ok thanks, I put the max db I can play but honestly it is very rare I play that loud. Again the main goal is sound quality. And the main objective of my initial post was the differences, between the different speakers.
Jed thanks for the info on describing the reasons for doubling up drivers.
Got to admit your 4T look awesome. Suprised that the boxes are small with so many woofers, at least compared to the others mentioned.

Other than the time my soundcard locked up and sent a death howl to a pair of PHL 1240's I was measuring, I've never witnessed 115 dB in my listening room...don't know that I'd want to for more than a few milliseconds.

You can build the 4T a bit larger than I have listed on the main page. Dougie made his about 80L or so. That way you'll get bass down in the low 30s. Maybe he'll chime in here. I've got people all over the world working on the Dynamic Series. Since it's a relatively new design... you won't find many builds here yet. However they are out there and you can check out my forum for the latest builds. There's a link at the bottom of my homepage.

I thought I would put my 2 cents in. I have also been researching for weeks and with help of many people here I think my decision is pretty much made up.
After reading many posts I would say that all the designs you mentioned are great speakers. They probably have all advantages and disadvantages and not sure if one compares to the other, it all depends on the application. Do you have a sub to support the low end? Where will they be placed? etc
If like me you are planning to put them in a corner setup, I was highly discouraged by the statements lineup, which was my first choice.
Jim Holtz pointed me to other designs and I found the Dynamic series.
Jed had been answering many of my questions and has been very helpful.
The only reason I have been hesitating is because I am in Canada and with the exchange,duties and shipping the cost is up there, but that's another story. His pricing is great, buy from him or buy direct and you will pay the same thing, except from him you get everything you need, including assembled crossovers, plans designs etc. Sorry I am in sales(getting carried away) Jed how about a commision. :lol:

So basically in order to decide you would have to look at size, your budget, building and soldering skills(Jed assembles the crossovers for you), application, ohm requirements, how low of HZ do you need? etc. I don't think you can go wrong with any of them.
Do a lot of research. So far I am sure I put in more time reading asking questions that the time it will take me to buid them.

As for not much on the Dynamic series here, well I almost sure you will see me posting here soon on my experience with the build

Good luck

:T I actually thought the OP was you for a bit because his question was so similar to your inquiry awhile ago. There's a half dozen builders out there for the 4t/2t as I speak. Dougie and another guy at the polk forum have posted reviews of the 4cc and 4T. Both feel they are really great... so hopefully as people start their builds they'll post the results. A lot of people aren't into the whole documenting the build thing; I've found. For example, I've got a few people building the Duet10 and haven't seen any wood cut for their builds yet. So maybe they're waiting for their schedules to allow time for this great hobby of ours.

The big 3-ways will do 110dB but they start to get harsh if the power isn't super duper clean. I've pushed up there with my big 3-ways (which uses the RS180 as a mid...)

The two biggest factors are going to be: Wife Acceptance Factor (WAF) and cost.

Start small and build a bigger pair next year.

Could always go with the Lineup F4. That should have good WAF.
