Rhythmic FV15HP review
Just putting up some basic info first on this new purchase, which will reach me sometime in mid Jan 2012, to replace an older SVS PB12+

How to connect this:
On the lower left corner is the switch for LPF. If you are not using AVR, then there are two methods of using the sub: 1) run the front speakers as full range and only use the sub to supplement the output. This is the high end approach because after spending tens of thousands dollars on speakers/amplifiers, some audiophiles are reluctant to introduce factors that can alter sound signature of front speakers. In this case, one should set LPF to either 50hz/24 and gradually lower the crossover knob to get the best integration. Phase adjustment may also be necessary. We have a program to help customers; 2) use HPF on front speakers. If the customer does consider this path, they may just consider using AVR with bass management after all. If budget is limited or one bought those HK AVRs without bass management (HK3480?), then one need to use HPF from the plate amp. Specify A370PEQ/H600PEQ amp option when placing orders. On the plate amp, set the LPF switch to 80hz/24 and set the crossover knob to 2 o'clock position.
With AVR, the customers should always set the front speakers to small and set the crossover to 80hz or lower. On the LPF switch, set it to AVR/12 if there is no dedicated LFE RCA input. Set phase to 0 and crossover knob to max. On A370PEQ3/H600PEQ3 with dedicated LFE RCA inputs, one can use either LFE RCA inputs (where phase and crossover knobs don't have function) or RCA line-in (where one should set LPF to AVR/12, phase to 0, and crossover to 80hz). The sonic difference of the two is LFE will sound slightly forward. It is good for modern/pop music. The sound of the other one is slightly lay-back, good for jazz and etc.
There is no switch to switch between signal sources. The system will play all signal sources at the same time. So it is up to the user to make sure how these signals are not playing at the same time (or overlapping as little as possible). Speaker level is just like LINE-IN in which the crossover and phase still have function. The recommended way of using it in a single system is obvious and I will not elaborate here. For a dual system, the dedicated 2ch signal goes to LINE-IN and the AVR SUB out goes to LFE IN. In 2ch mode, one will run the front speaker full range. Adjust the phase and crossover so that sub gets good integration. For the best result, set the LPF to 50hz/24 and then adjust phase and crossover controls. In HT mode, set the front speakers to “SMALL” and set crossover frequency to 80hz. Don’t touch any control on PEQ3 now. Use your AVR menu to set the subwoofer volume level. Adjust in the subwoofer distance menu so that you get good phase alignment. The idea is that after you set the front speakers to small, there is very little signal below 80hz that can pass via line-in to the sub.
I have no financial interest or other interests in any of the items / events I write about.
