Adding Sub to current system

I have a Rel B3 with my Dynaudio C1's and getting the phasing right is the tricky part. I have mine crossed over at 32hz (C1 rated to 45hz) and the gain up and there is no BOOM here. Honestly I will say if the phasing is off and or crossed over too high it will have a boom. I get that last '10%' but it really adds to the mids and overall sound stage.

Look into either a 215 or larger VMPS sub. They are totally adjustable to your room/system and can be bought with amp, with outboard amp, or without amp. I have the 215/with VSS upgraded driver and the bass blends with very quick speakers so that you have NO idea there is a sub in the room except the box. The dynamics and sound quality are unmatched at anywhere near the price. You could get one with an amp new for under 700.00 delivered to your door for the 215 or under 900.00 delivered for the larger. You can make the sound rounder, if prefered, or tight and punchy, or anywhere between. Just plain awesome sub.

Sounds like some expertise is required in implementing a sub with smaller monitor speakers. The Sonus Faber speakers sound very good and I don't want to mess it up. One procedure was mentioned on this thread, yet I wonder if there is a standard approach to connecting the sub, there is also the cost of IC's to the sub if it's at a distance. My current location idea is about two meters from my system, however I wonder about vibration, maybe if the sub I choose accepts speaker wire connect from my amp connected right to the speaker outputs??
Thanks,

I would absolutely use or attempt to experiment with a sub. You truly don't know what you are missing without the added weight of a few dB of 20-40 Hz. I have tried a REL sub recently with full range floor standing speakers in an upstairs room with dimensions that just won't support enough below 40 Hz. I found the REL integrated seamlessly with my room/system. REL recommends using the supplied Neutrik cable that hooks directly to your amplifier speaker terminals. This allows the quickest bass response and integration.

You have absolutely nothing to lose but some time. Get a used REL studio or strata on Audiogon and try it for a month or so experimenting with crossover and room position. If you don't like it enough to keep it, put it back on the 'Gon. REL subs sell like hotcakes in the used market. You won't lose a penny of your money. I'm betting once you try it, you'll keep it.

Hi Rpg,
My current speakers are flat to 40, I came across one of the decent velodynes used and picked it up. It is rated down to the low 20's. I put it right next to my system with a 15' cable. It was peeky, I slowly moved the crossover point downward starting @ 60. I ended up just below 40. I then moved the sub about a foot at a time toward the corner. I pointed it in, I pointed it out, I pointed in down one wall, then the other, I increase output, I have a phase dial and used it ever so slightly. I ended up with a very nice result. I've had a few audiophile over, none even knew that it is there.... until I turn it off... I can say without hesitation the differences are indeed minor, but clearly add to the enjoyment of the music. Good luck, Tim
