njolliffe''s Dad here
They are mains and need to be paired with subs, crossed over between 80 and 100Hz.
The TLAH's are paired with a UK manufactured Sub - BK Monolith DF ported reflex - a huge beast. Cross over is handled by Audyssey MultEQ XT32 built into the AV amp with the sub's crossover disabled.
The crossover reported by Audyssey for the TLAH mains is 90hz. I think njolliffe was hoping they'd be good down to 80hz, but for me anything under 100hz should be fine - especially as the sub is now placed between the two mains.
Using white noise and a basic sound level app - it's quite easy to see there's some significant drop off in levels below 100Hz, but I guess Audyssey EQ settings are able to boost enough at 90hz not to depend on the sub.
As living room furniture, the oiled oak fronts with recessed rear speaker mounting looks amazing. As mentioned, I had a few stability issues on the soft carpet flooring at first, but adding some spiked feet, and using the feet adjustment to tip the units back just a little, soon overcame that minor issue. Sound wise they're very crisp at the top end and once Audyssey EQ is doing it's tricks the TLAHs sound much clearer than my previous Mordaunt Short 906's, which until these arrived at Christmas I'd always found to be pretty good.
Audyssey EQ curves are quite different between the left and right speakers, but I suspect that is much more to do with room acoustics - which are far from ideal - than any differences between the TLAHs. When I find the time I plan to do some more testing swapping the speaker positions over.
These are bi-amped into a 7.1 sound system used for both music and movies. The increased sensitivity of the TLAHs over my MS906's exposed some white noise hiss from my Yamaha AV amp, which was a great excuse to move a little more up market and up to date.
Looking forward to pairing these with a matching centre sometime soon.
