What sub under a grand?

Try a Monitor Audio Radius 390. It is one of the fastest sub's under 1 grand. In reviews people are very positive. The timing and control is awesome. It is fast as a rocket, with stunning looks!

I depends were you will use it for. For music I would never choose for a bass reflsex subwoofer. Speed is the most important parts. This most common mistake I see at clients is that they buy a big subwoofer. It is not about the size and freq. respons. The best subwoofers are always those who have the best response. A better timing gives you a superior level in integration. Audio is al about looking further!

It depends were you use it for, but these sub's are not that fast. I demo and compare subwoofers for timing and integration. On the other hand I want to use them till at least 120 hz. With Audyssey you can easily get a very good level of integration with a subwoofer. Above 80hz low freq. become physical. Beside this you get a more deep stage as well. In the pastI sold many rel subwoofers. We never went further than 70hz. These days some subwoofers use material and magnets so you can use them easily till 120hz or even higher. In all my tests this makes a big positive difference.

The idea's to use it higher than 80hz came from Audyssey. To be honest I never went higher than 80hz. So it was complete new for me. I thought it would not make a big difference. But I was wrong. The overall sound became more involving, stage depth became even bigger. Sharper individual focus of instruments and voices. I started at 120 hz, at the end I stopped at 140hz. The thing what is important that you need subwoofers with a fast response. This depends about the material use of a manufacturer. And also the magnet is important for the control as the amp which is used.

These days I set most subwoofers till 120hz of my clients. Audio always will be about quality and comparing. When I would have followed all rules in audio I would never be were I am now.Looking for a higher endresult in sound time and testing is needed.

Low freq. are very easy to be explained why they have such a big influence. When the freq. goes deeper, there will be more emotion. It is that simple. Ofcourse a concert without a deep low freq. is useless!

Wolfie is telling his bullshit again. When you compare
subwoofers in timing and speed there are clear differences.
The subwoofers with a faster response, better amps and better
magnets can be used to a much higher freq. response against
those who are slower and are less controlled.

Wolfie is using a more than 10 years old Rel Q150 subwoofer.
When it came out, It was a very nice subwoofer. I sold a lot
of them. ( I prefer closed subwoofers with frontfiring) But we
are now living in 2014. The quality has changed a lot. There
are now different rules and possibilities compared to the
past.

I do business with a company who also does the distribution of
SVS. Personally I think they are not the best looking. But that
is not the biggest limitation. I have said it many times;
subwoofers is all about timing and speed. They do not use the
best material in response. I have listend a few times to them. I
could not sell them to my clients. Because they are not good
enough, it is that simple! These timing limitations still many
subwoofers face. People look at how big a speaker unit is and
how many WATTTTTTTs the amp is. I would advice; please use your
ears and focus on the level of integration with your speakers.
