Thiel Owners

At the risk of appearing pedantic, If one were to mate sealed boxed subwoofers to sealed boxed monitors, and with perhaps some DSP one might achieve equal time coherence to that of a full range time coherent speaker. 

One caveat is that the subwoofers might have to work further up the frequency range (an area in which they become progessively more clumsy) to augemnt the the lessened upper bass output of the sealed box monitors (compared to typical ported monitors).

On the other hand there could be advantages in room placement and specific power requirements to such a pairing, Though not without added complexitiy. 

Getting such a system to work cohesively is not trivial endeavor

Addendum: The above presumes that the sealed box monitors are themselves time coherent and the use of the appropriate crossover to sealed boxes subwoofers are used

Ultimately it is the ports that are the obstacle towards true time coherence.

There goes Duramax747 dangling that carrot in front of us to entice us along.

Yes the thought is enticing and I can't wait for the results.

With Unsounds addendum I envision a pair of Thiel PCS or SCS 4's with Tometiel improvements positioned above a  pair of SS 2 subwoofers using the Thiel Integrator driven by a nice pair of Class A monoblocks.

Can I borrow somebodies credit card mine just started screaming and passed out.

Have a good weekend everyone.  

I wonder if it would make sense to locate the subwoofers closer to the listener to achieve better time coherence, similar to the sloped baffle of the speakers?

@ig316b, As best as I can remember at least some of the SCS’s came with port plugs. I’m not sure if those models were optimized for use with or without. Often times used models are missing them. I don’t remember if the port plugs were offered for the PCS’s. I believe the earlier SCS’s came with 2’nd order crossover which are not as time coherent as Thiel’s models’ that featured 1st  order crossovers. Generally the lower the monitors go; the better. Keep in mind there are other parameters considered when designing between ported and sealed boxes.
 

@jwei  Bass in rooms can be problematic. Room treatment for bass issues can be cumbersome. Reducing reliance on room treatment can be less expensive, and less intrusive. I suspect placing the subwoofers for the best room fit first, and then dealing with the spacing / time alignment with the appropriate monitors with now less intrusive DSP might be  best.
