Small Footprint Servo-Subs, Horn Option & Concrete Notes

't

I am involved with a project to build a crazy high end audio listening room. The pour in place concrete room is going to have concrete boxes as part of the foundation to put 5 subwoofers in. These will compliment a YG Acoustics top end speaker system.

It seems building subwoofers is the best choice as using the concrete foundation as the enclosure seems pretty good. We would pour concrete to the correct dimension required. Extremely good amps would be located by each woofer to drive each one. The 5 are spead out over the room in well modeled locations.

So... The question is what driver. Im interested in suggestions. Price is no object. Performance is what counts. The bottom octave needs to match the performance of the YG's.

Some drivers have been suggested.

TAD TL-1801
AuraSound 1804
AuraSound 1808
AuraSound NRT 18-8

The questions then also begin for closed box or ported.

A Datasat will be used to do any electronic crossover needed.

Primarily the subs will be used for the LFE, but as the rooms main pourpose is 2 channel audio we might want to use the sub system for the very bottom octave on 2 channel audio from a 100% analog signal chain.

So... Any thoughts ?

Not DIY (Don't need to pore the enclosures.)

Their are far more expensive options out there, but these should be more than sufficient for your application.

Alternatively you could integrate large Klipsch corner horns into the room design.
This would be an engineering challenge, to build the forms to do this.

If you go with concrete enclosures, be sure to treat them with a moisture barrier after they are formed. Place a schedule 80 PVC conduit nipple in the form before the pore to serve as a wire raceway later. A metal baffle plate should be bonded to the concrete for driver mounting.

Other driver candidates should include:
