Studio engineers requiring powerful and precise low-frequency reproduction will be dazzled by the black HEDD Audio BASS 12, a compact studio subwoofer that's compatible with any previous model studio monitor, but it really shines when used with the latest HEDD MK2 models.

The BASS 12 features an onboard Lineariser, a phase linearization tool that audibly improves spatial reproduction as well as port plugs that allow the monitor to go from a bass reflex design to a sealed infinite baffle. The rear panel features a Closed or Ported selection knob, a Low-Frequency Extension control, and switchable low-pass filter with different crossover frequencies including two LFE modes.

The BASS 12 also features the Linear Phase satellite-subwoofer system, which applies a switchable group delay at the satellite output. The potential listener distances between subwoofers and satellites can be compensated in .5 dB steps within a ±2m range. When used with HEDD MK2 monitors, a Linear Phase satellite system can be installed for the first time. The 12" honeycomb composite woofer provide an accurate frequency response of 20 to 80 Hz with a maximum SPL of 115 dB (at 1m).

The sturdy unibody casing features a lacquer finish for high durability and overall aesthetics. The enclosure ensures that the cabinet remains stable and provides effortless audio, even at full power. The ICEpower amplifier offers 700W and is universally powered for compatibility anywhere in the world. The rear panel also features two balanced XLR Inputs and a digital AES input and throughput.

Benefits

Onboard Lineariser

  • Implemented in the MK2 and subwoofer models is the well-known Lineariser, a phase linearization tool that leads to perfect impulse response and audibly improved spatial reproduction
  • The BASS 12 utilizes a lacquered finish for high durability and great aesthetics

CoP Technology

  • Users for the first time can choose between the energy and bass capacities of a modern bass-port design and the painstaking precision and control of a closed-cabinet approach
  • Removable plugs for the bass reflex tubes, together with accordingly designed filter setups, allow optimum results in either mode

Linear Sub Satellite System

  • HEDD Audio introduces a completely phase-linear Sat-Sub system. These are the first satellite-sub systems that are completely right in time by combining a phase-linearized subwoofer with a correspondingly time-delayed (group delayed) satellite output (satellites sold separately)
  • Additionally, the listener can compensate eventual distances between subwoofers and satellites to stay with linear phase reproduction for the complete system

Features

  • Woofer: 12" honeycomb diaphragm
  • Analog inputs: 2 x balanced XLR
  • Digital input: Digital XLR AES 
  • Output: Digital XLR AES through
  • HEDD Lineariser Disengageable Delay: 30 ms
  • Switchable low-pass filtering for use with different crossover frequencies including two LFE modes
  • Switchable LF range normal / extended (15% lower=less SPL max) and a +10 dB option for LFE
  • AES interface input selector for analog, AES left, AES right, or AES mono
  • Input sensitivity pot. range: -10 to + 4 dB, so AD conversion can be optimized
  • Gain: Analog pot from -12 to +12 dB
  • Frequency response: 20 to 80 Hz (-3 dB)
  • Maximum sound pressure level: 115 dB SPL

Best Dog (Puppy) Toy I've Found
Color: Orange
This is a fun toy for me as well as my puppies! When it arrived I opened it right away. I was anxious to get my Pup's playing with something that wouldn't require me to play with them. I put it down and it was charged and ready to go. I had no idea what to expect. All three of my Pups were interested in it. (Which is unusual because two of them are Shih Tzu's and don't pay a lot of attention to most toys.) It's safe and really cute to watch. My youngest pup had been playing all day and was tired when I finally took a photo. I can't tell if the video uploaded correctly but if it did you can see how much fun it was. It is very durable and can actually turn itself over and go across the floor. It charges fast and will last a day and a half or two depending how much it's been used. It does go to sleep if no one is playing with it. They furnish you with an extra top and a fresh "rope." I really appreciate how much customer service is done with this item. I will watch for more of their items to purchase.

Buy 2 at a time for a fun experience
Color: Orange, Color: Orange
What’s better than 1 toy? Answer: 2 toys! I love using two at a time. More stimulation and fun! We use these to get all the energy out before nap time. They keep him occupied and running in two different directions. The rope part of the toy is the perfect size for him to grab onto. It came with a replacement for a wheel and rope and haven’t had to replace it yet. Toy has held up with daily play and still works perfectly.

How many dog toys have you bought that just laid on the floor unused?
Color: Orange
New husky has more energy than an entire pre-school - even being walked more than three miles a day wasn’t sufficient to drain her excess energy. I threw the dice on this - and it’s AWESOME. Comes with an extra rope and an extra side piece. Rechargeable with a USB-C cable. When you turn it on, the blue LEDs flash, the entire device buzzes, bounces, and races back and forth across the floor. After a couple of days of uncertainty, my new husky LOVES this. She chases it around, grabs it by the attached rope and carries it from room to room. After a short bit of activity, the toy goes into ‘sleep’ mode, until either the dog touches it again or a timer has elapsed, and then it fires up and starts buzzing and racing around the floor again. From a full charge, the toy will keep your dog entertained all day. Bright orange color makes it much easier to find when it’s rolled behind the toilet (as it did this afternoon). Sturdy. Highly resistant to chew damage. If this one wears out or breaks, I’ll absolutely get another one.

Puppy interactive toy
Color: Orange, Color: Orange
It’s a great toy as it keeps my 5 month old puppy very entertained! It is pretty hardy and made of good material as she tries to throw it around and chew it. She does swing it around and the hard part will hit her. She doesn’t seem bothered by it tho lol good size and minimum noise When I first introduced her to it she was a little scared but now she gets excited to play with it once it finishes charging.

Cool toy. Fun for all
Color: Blue
A cool toy. entertainment for the dogs but more so for the dog parents to watch the dogs reaction. Comes with an additional rope just in case, which I loved. Only side note I would say is that the fast mood could be a little faster. My Golden retriever figured out the speed in less than 24 hours and now picks up the toy to try to chew it up, instead of chasing. With him attempting to chew on the toy in the small time I give him, there are no teeth marks yet…this toy appears to be durable. We play in short increments but enjoy the toy.
