Advice on a sub please

[Mattwah]

Hi
I’m looking to add additional bass to my setup
Currently have a streamer and a cd player running through a
Densen B-130
Into
Monitor Audio Studio 89’s
Love the high end and the mods are excellent but suspect some additional bottom end could be very handy

Does anyone have any thoughts on the following 2 options


Monitor Audio Anthra w10

Perlisten r8s- currently on sale for about 1000 less than the MA

Cheers

Matt

For Audio, I would seriously look into the Rythmik Audio Servo controlled subwoofers, mine are 14 yrs old and still sounds better than some of the modern subs that i have/had , including Polk HTS 12, SVS SB3000, SVS PB12 and and Klipsch 12 SW something

Rythmik has been out of inventory for a few months now.

The container left port a few days ago as advised from the AVS forums site...

So if you put on your most bass-heavy music and crank it up, do they distort? Are the cones moving like nuts?
- If so you MUST get a highpass filter in there, which whilst your Densen looks very flexible I don't see any amplifier input to accomodate an external highpass crossover. Does it have such function built in?
- If they don't really distort then you can use one of the preouts to feed a powered subwoofer and adjust the lowpass filter for best response.

I don't know those particular sub models you mention. I will observe as a loudspeaker engineer that
- More cone area is better, like 12" at least or better yet 15"...18"...21"!!!
- A bigger box is WAY better
- "Hoffman's Iron Law" would seem to imply that a small box with a small cone can perform as well as a big woofer in a big box if you apply more amp power. That is simply not so, due to physical limitations of building the drivers, and because small enclosures appear to reduce the efficiency in the very low bass.

Thankyou, I don't ever drive the speakers hard enough to create distortion ... unfortunately, as good as the Densen is- I'm using pre outs into a powered sub and dialling in the high pass filter ... I ended up grabbing the monitor Audio Anthra W10 sub a couple of days ago ... room is small, so it is definitely big enough for the job at hand... thanks for your detailed and helpful response.

I have contacted Rythmik via phone and the contact page several times. After speaking with Brian 2 times, I have to wonder if they are interested in selling the DIY kit as advertised. Not only do they not reply back, but hem haw about integrating their product for my needs. The poor customer service seem strange. I hope I am proven wrong, but have my doubts.

If you’re looking at the Perlisten, it’s hard to argue against. I have several RSL subs and love them. HSU Research and Rythmik are the two others in that category and would likely fit your budget. They are rather large, which may not fit your space.

My RSL 12S is nearly the size of a laundry machine. It is wonderful but was hard to integrate with the decor.

For a smaller (not micro) quality performant option that is still affordable you may also consider the sealed SVS SB2000 Pro. Because it is smaller it can also open the option of deploying two - which would significantly improve consistent bass coverage throughout your room.
