Make me more confused in your thread you said that Monolith is the best in group for delay ( good for music), but RussWill & Angel Eye recomand SVS PB12+
The Monolith does appear to have the group delay of a sealed sub, that's one of it's tricks, but it's not the only important factor for good music reproduction. Impulse response, it's speed at starting a noise and stopping it, is another.
For what it's worth and I've said this before, the qualities that make a good movie sub, make a good music sub. High headroom for uncompressed dynamics, low distortion, extended frequency range, tight impulse response and smooth group delay. All of those are qualities you want, whatever you're playing.
Moreover, someone said seal box sub is not perfect for music when comparing to ventilation sub. the orthers said, seal box sub did not go deeper than the port one.
Generally, for a given price, ported subs will go lower and deeper with less distortion. A sealed sub may have to compromise one of these abilities to manage the other two. The SB12 will go practically as loud as a Monolith, but achieves it by sacrificing the last 5-10Hz of extension to do it. Remember, I'm stating this in the context of price. Higher power, more expensive sealed subs can reduce this compromise.
Both of the above questions are pointless, if you can't achieve a good integration with your room. Suffering a serious room resonance or cancellation will overpower any of the subtle differences these measurements show. A serious resonance, will mask deeper notes, making the sub sound monotonous (one note), boomy and slow. All of which will be crap for music (and for movies).
And this is why I think the SB12 is a great candidate for music, where the last half octave of bass depth doesn't matter as much. Unless you are a church organ addict who wants the deep pipes to rattle your eyeballs!.
Smaller subs are easier to integrate because they allow a greater range of positions in the room. The SB12 has additional features (room size compensation and EQ) that will further allow the ultimate goal of a nice flat frequency responce that will give a tight, fast, deep, powerful sound that will underpin and drive music along, instead of blurring and slowing it.
Other threads confirmed Front F would have a ideal listening position for at least 3-5m while the DownF would not
I'm not sure that this matters. DF may diffuse the sound more than an FF, but given that it is distortion that tends to reveal the subs location, a low distortion sub shouldn't real care which way the driver faces.[/QUOTE]
I am not in 2 minds but multi minds
Welcome to subs! It gets less complicated as time goes on. Honest!
