Dymension DM70 features a 1" aluminum oxide 2 x Hard-Dome Tweeter, a 5.25" Midrange and 1 x 10" Polypropelene Woofer. On the other hand, the BP-9060 features a 1" annealed aluminum dome Tweeter, a 4.5" Midrange and 1 x 10" Polypropelene Woofer.
Frequency Response
Dymension DM70 has a frequency range of 30-23 kHz whereas BP-9060 has a frequency range of 18-49k Hz. With a minimum frequency of 18Hz, the BP-9060 can go significantly deeper on the low side and provide stronger bass compared to the Dymension DM70's min frequency of 30Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Impedance and Sensitivity
Dymension DM70 is a 4 ohms speaker compared to the BP-9060 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Dymension DM70 can provide this impedance level.
These two speakers also have different sensitivity levels. Dymension DM70 sensitivity is rated at 90 dB and the BP-9060's is rated at 92 dB. This 2 dB difference makes the Definitive BP-9060 a more sensitive speaker compared to Definitive Dymension DM70, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Dymension DM70 and BP-9060 have the same power range of 50-300 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.

Input Type and Bi-Amping / Bi-Wiring
Dymension DM70 features 5-Way post, RCA type posts and BP-9060 has a 5-Way post, RCA type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Definitive Dymension DM70's and Definitive BP-9060's external dimensions. Definitive Dymension DM70 has external dimensions of 1204 x 287 x 407 mm (47.4 x 11.3 x 16.0 in) whereas Definitive BP-9060 has external dimensions of 1132.0 x 281.0 x 351.0mm (44-9/16 x 11-1/16 x 13-13/16inch).
Definitive Dymension DM70 is clearly the larger of the two speakers. Its body is 6mm wider, 72mm taller and 56mm deeper than Definitive BP-9060.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Definitive Dymension DM70 is approximately 1168.1cm2 / 181.1inch2 and base area of the Definitive BP-9060 is approximately 986.3cm2 / 152.9inch2. The Dymension DM70 requires 18% more surface area than the BP-9060 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Definitive Dymension DM70 weighs 33.60kg / 73.9lbs and the Definitive BP-9060 weighs 22.73kg / 50lbs. This makes the Dymension DM70 48% heavier than the BP-9060.
Here is a comparison of how Dymension DM70 and BP-9060's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Definitive Dymension DM70 costs roughly 1.7x what Definitive BP-9060 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | Definitive BP-9060 digs deeper - 18Hz against 30Hz. |
| Amplifier needs | B | Definitive BP-9060 is more sensitive (92dB vs 90dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Definitive BP-9060 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | Definitive BP-9060 is easier to place; Definitive Dymension DM70 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Definitive Dymension DM70: Atmos drivers; Definitive BP-9060: Atmos drivers. Definitive Dymension DM70 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | B | Definitive BP-9060 is cheaper - $2,398 against $3,998, about 40% less; arguably a different class. |
A Definitive Dymension DM70 B Definitive BP-9060
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Definitive BP-9060 is the easier recommendation: it leads on most of the measured areas and costs less. Take Definitive Dymension DM70 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 30Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, Definitive BP-9060 is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
