In need of a small sub to augment low freq when using my Von Schweikert VR-1 monitors which reach 55 hertz. This is a 2.1 system only, 80% for audio use. Now here's the kicker, the room is 20x17 with 11" ceiling. There is an 8' opening into another room. The floor is hardwood. Realize that with these characteristics a 12 or larger sub is common, but space a concern with this room. Can products such as the LFM-1 compact or ML Dynamo offer just the right bass to satisfy those recordings that require sub 50 hertz listening. AVR is NAD, CD is CA Azur, Table is Transcriptor. Thanks in advance for your comments.
