The Tonian TL-D1 that everyone considers a bargain, have a frequency response of 42Hz-40KHz. Limited bass response."
Yes the specs indicate that and I would say they are accurate. I would also say that with proper placement and adjustment of the bass port, the bass sounded like that produced by my Spendor 1/2e. Something I can easily live with.
Prior to buying my Audiokinesis speakers I looked hard a Dru Zuids and Audio Note AN/E. Logically, I always thought the Audionote would be a logical progression of my love for the Spendor sound, but with deeper bass. I will own a pair someday, but not yet.
I consider the Tonian TL-D1's a poor man's AN/E in some respects. However, you can get an AN/E kit and if you're handy put it together for around $3k. Now that would be something.
