Forgot to mention that my pair is the Studio 1M, for aluminimium metal drivers.

Stunnig low, tight bass with complementary mids and highs. Transparent enough for quite a few upgrades.

Will sound sluggish when not driven properly. Will sound thin and small with lower quality stuff.

Needs to be driven properly - not just power. Quality current drive seems to work. Have heard some power amps >100W that sounds mushy, soft and indistinct with these TDLs but the Aleph 3's 30W seems to work wonders.

With a slightly laid back perspective, these TDLs are most un-CerwinVega like and hence not that suitable for hard Rock or fast, high enegy music. Most suitable from pop to jazz and classical. Classy.

Highs are open but needs quality ancillaries else it may sound hashy. Listen without the protective tweeter grills.

Mid is transparent and can float depending on quality of amp although not as open as the top quality speakers.

Bass is ample yet controlled (amp and source important). The whole package seems to be quite even across the frequency spectrum from this compact floorstander.

Bass (transmission line).

Only medium with pop music.

This are stunning speakers. The transmission line makes miracles and is still used by some manufaturers of speakers such PMC (used by great studios like BBC).
You simple don´t believe how could a small floorstander speaker give you such deep bass!!! it´s like if you been using one or two subwoofers.
But attencion!!!....a bass with control and so deep that you can feel inside even at low levels.
Now i will upgrade my amplifier (Audiolab 8000A) for a ODYSSEY Stratus 150 and this will bring my TDL´s from live to hiper-life!!!

I have had the Studio 1 for about two years. These speakers are quite good at what they were designed for, production of the entire range (ie 27Hz to 20kHz) in a small to medium sized room. The consistency throughout the frequency range is a pleasure to listen to. Bass is tight, extended and tonally accurate Imaging is good, and voices and piano sound very good. I wouldn't get these speakers if you want continuous pumping rock (though it does do it). The real forte of these speakers is the relatively subtle, low bass in classical and jazz. There isn't enough distortion/false bass for techno(so i'm told!). The bass/mid has a small diameter (about 5"), but relies on the transmission line and high excursion of the driver. If pushed with heavily boosted low bass of movies or some modern music, it will start tapping. Other than that, shes a gem:-)
