Svs sub : should i go with sb13 ultra or pb 13

hi guys,

first, thanks for your posts. i really appreciate.

About your recommandations :

i have Reference 3A (grand veena) speakers. These speakers are for me incredible 'cause they have a huge Soundstage. I planned to use a Dspeaker dual core for the speakers not for the subwoofer considering that SVS's subwoofer have a parametric EQ. So i just need a sound analyser to adjust the sound's sub.

About your recommandation to use 2 subwoofers, i not sure that i could go with that configuration (space issue)

But about the initial subject, what sort of subwoofer i need to used (sealed or ported) in an audiophile perspective (only), i have noticed that you have different opinions.

Rel designed only Sealed sub, in the same time Wilson audio did a ported subwoofer (Thor's Hammer - i had a chance to listen it, and trust me it's fanstastic)

So, if they 're sealed and ported subwoofer on the HI-FI's market, did it means that the choice must be oriented by the size of the listening room (12 x 23 ft in my case) ?

Have you tried speaking with the folks over @ SVS? They have a selection wizard that lets you input details about your room, gear etc and will then make recommendations. You can then speak to the people @ SVS via e-mail or phone. I did this a year or so ago and had a good conversation with SVS. I didn't go with any SVS subs due to multiple system changes but they were cool to talk to.

Best of luck

Sealed subs generally provide tighter (more highly damped) bass than ported models. You can check "group delay" specs at HTShack.com (if they're available for the models you're considering) and you'll see one measure of this characteristic. The trade-off is less true deep bass output per cubic foot of enclosure volume.

Most people prefer sealed subs for music, because you don't need a ton of clean output in the 20hz region for music (tho you might for cinema) and tighter bass is often (tho not always) a better match for high-end main speakers.

I have an SVS PB13 Ultra in black gloss with Casta Acoustic D8 floorstanding speakers and they blend perfectly. I run it at 80hz crossover and maybe 2 on the dial with all ports plugged. Just stunning. Mind you I had a $600 Hifi Pyon Mythology sub platform madeI for it because the little rubber feet did nothing for it. Now the pitch is perfect, tight and well tuned. I would go for either SVS. You can't go wrong. Good luck!
