At $2,000 MSRP, this was a super bargain center speaker. Especially when it is $2,500 cheaper than the HTM2D center speaker. It may be slightly smaller, does not have a diamond tweeter but it shares the same four driver, three way configuration of the HTM2D. And it definitely does not sound anywhere close to being half the performance of the HTM2D. In fact, you would really need to nitpick to declare the HTM2D the clear winner. The major differences between it and the HTM2D is that the latter is about 10% bigger in terms of volume, weighs 22 lbs more, have 7″ bass drivers instead of 6.5″ on the Nautilus HTM1, have two rear ports (none of the HTM1) and of course the diamond tweeter. Frequency response for the Nautilus HTM1 is 49 Hz to 20kHz while the HTM2D is 41 Hz to 28 kHz. Sensitivity and nominal impedance are the same at 90 dB and 8 ohm. Dimensions of the speaker are 30″ x 12.5″ x 12.5″ (WHD) versus 33″ x 13″ x 15″ (WHD) of the HTM2D.
The manufacturer recommends a minimum of 50W to drive it but we pumped 100W into it and it was perfect. The audio presentation was crystal clear, mids and bass was punchy and nicely textured and the soundstage was wide and tall. Speaker is shielded so you can place it very close to your TV screen with no impact.
Cosmetically, the speaker looks great. Minor scuff marks here and there but nothing major. One of the clear plastic cap on one of the speaker binding post has come loose but you can still tighten it by twisting the metal body of the posts (if you are using spades), no issues if you are using bananas. We don’t have the original box but can securely pack it for safe shipping. Local pickup from our store can be arranged.
