JM Lab Utopia Sub

the sub works well with the minis--fills in the audible gaps if you will. i found it a bit less impressive (perhaps less necessary) with the mezzos. i guess i'd "reccomend" it for use with the minis and say it's a coin toss/personal opinion for use with the mezzos.

Randalleron - Thank you very much for your feedback. I guess there are not too many JM Lab Utopia Sub users here except yourself. Have you had any experience with Velodyne HGS series and how would you rate the Utopia Sub to the Velodyne sub? Is it always better to stick with the same brand for compatibility? Thanks.

trantq--sorry, i do not have any experience with the velodyne. i don't know if it's always better to stick with the same brand for compatability but i think that you should start with the same brand. that is to say, for your speakers (especially ht), the presumption is that the same brand should be the snuggest fit. but like everything else i'm sure there are exceptions to this rule. good luck.

Randalleron - Again, thanks.
Lets see if we have any other experience Utopia users who might want to share their experiences with us. By the way, do you prefer the Utopia series over Sonus Faber or B&W? What other speakers do you like beside JM Lab?

I have recently traded in Aerial 7B's with two Vandersteen 2W subs. While the subs filled in the lower regions, their greatest benefit was that it permitted more power to go to the 7B's and, boy, did they open up! Much more dynamic and lively. I considered the MIni's with the 2w's, but the Mezzos are in a different league...even with the subs, the Mini's aren't as complete a speaker system as the Mezzo's...the Mezzos are special, particularly when mated with a great amp.

Hi
I owe JMLab Mini Utopia partnered with YBA amplification and cd player.
I too want to put a sub to filll the frequencies below 45-50Hz I am thinking the REl Strata III has anyone any experience?
I also would like to ask your opinion on different connections (through the second output of my preamp or in parallel to the amplifier speaker terminals.

There is also another thing that puzzles me if one is to use a sub what happens to the frequencies that both the main speakers and the sub produce.Is there any overlapping?since there is no active crossover in the chain??
I would apreciate your thoughts and insight

Robathome - Could you please suggest a few great amps for the Utopia speakers? Tube or solid state?

Mahler - I believe going low level from the pre-amp to the low level input of the sub would be better than parallel speaker cables between the amp and the sub.(IMHO)
May be other experts can provide more information for you. Since you owe the Mini, why would not you consider the Utopia sub? Is the Rel better?

I will try JMLab sub also but is more convenient to see how it matches with a sub first and then go for the Utopia sub
Any comments on the active crossover and the possible overlaping frequencies??

I have no experience with the active crossover but I believe it blend in the frequencies between the sub and the full range speaker a little better. In regards to the frequencies overlaping between the sub and the full range speaker when you run in parallel is not an issue if you take the time to tune in the sub correctly. Try to adjust the sub cross over first then adjust the volume control and repeat until you feel right. If you have the Mini Utopia, you can start the sub at 60hz and slowly go down to about 40hz (until the sub and the Mini blend in). I believe the Mini goes down to 50hz so play around within that range. I hope this help. If we have better suggestion, lets hear it.
