The TC Sounds LMS-R
- identical diameter and mounting hole pattern.
- Thiele/Small parameters close enough to the Eminence drivers that they will work quite well within the DTS-10 tapped horn cabinet.
- the TC Sounds LMS-R drivers use the "linear motor system" method of reducing distortion near its excursion limits.
- 25.4mm of Xmax (31.75mm at 70% BL) versus 15mm (23mm at overload) for the Eminence drivers.
- 3 to 4 dB greater SPL output capability than what the Eminence units can do.
- 1000 Watt (RMS), 4000 Watt (peak) thermal power rating.
- less efficient by 2 or 3 dB, requiring double the amount of amplifier power just to provide the same volume as the Eminence units.
- less smooth response than the Eminence units provide. (but since a DTS-10 requires equalization to provide a smooth response anyway, this is not really a concern)
- the deeper magnet structure of the LMS-R driver won't allow it to sit flush in the corner mounting hole unless an 18mm thick mounting ring is created. (3/4" plywood?)
- 15 pounds heavier than an Eminence unit.
- More expensive (about $30 more each) but free shipping from Parts Express might cover the difference.
- Currently out of stock. (Parts Express is estimating next delivery is on July 18th, 2014)
Kutlow switched to the TC Sounds drivers and he said in post #9952 that "They sound better at all levels. The bass has a different sound to it. Harder, cleaner and I have yet to push them to their limit! Before the swap I was not happy with the subs. Now they can keep up..."
I'm interested in getting them because they seem more robust, actually have a warranty (5 years), and are usually
available from multiple sources. (Just not right now
But I'll have to find a more powerful amplifier (that's quiet) before I decide to purchase them.
