Subwoofer Advice For Stereo Music System, Not HT


I recently purchased new the following:

Jolida JD302BRC Tube Integrated Amp
Jolida JD100 Tube CDP
APC H-10 Power Conditioner
Wireworld Cables and Interconnects

all added to my current Klipsch KG5.5 floorstanding speakers.

I absolutely love the mids and highs produced by this system, but the lowest frequencies, while nicely detailed, are just not quite balanced with the mids and highs. I have had the system for a month now, and have at least 40 or 50 hours on the system. I have tried numerous speaker placement options, and currently have the speakers placed almost against the back wall. This gives the best bass, but still not quite what I seek. I have decided I may have to add an active subwoofer. I can't help but believe that the proper sub would be the final piece to make this system really shine for my small 13x14 listening room. The system is used only for music, no home theater.

Given the above, what do you think I should I look for in a sub? I am currently looking at the Velodyne MiniVee or the Velodyne SPL-800R. I would think these models should give me the added bass while keeping distortion and boominess to a minimum. They are also sealed instead of ported, which I have read is better for stereo music. Am I on the right track here, or are there other models/brands I should consider? My budget is $1k or less.

Also, the Jolida int amp has two sets of pre-outs. One fixed and one variable. Which would be more beneficial to use for the sub, or should I just hook the sub to the speaker binding posts?

Thanks.

I like the Velodyne for music. If the REL is in your budget, they are nice too.

DO NOT hook your sub up with the fixed pre-outs of the Jolida. You need to vary the output to the sub so its output goes up and down with the main speakers. Do what Garry said in his last paragraph. Good advice.
What about Vandersteen 2Wq a very "musical" sub that lets you set the hi-pass filter value to blend with your speakers and also has db matching to your speakers and adjustable" Q" from tight (jazz) to bomb explosion, it's best at the jazz end though. The signal is coming from your amp so it takes on the Jolida's characteristics.
you have the right idea re sub addition. fwiw, i use the same spkr outs to run to my MK powered sub which has all the controls built into it. i run a thinner gauge wire from the binding posts from a different position on the 5 way posts to the sub. exlnt results. i have the jolida 502b and yes these 'smaller' tube amps do benefit from some s.s. muscle in the deep bass. the current sent to the sub is miniscule and heavy spkr cable hardly seems justified in this sense. jmo
I line up behind Samhar on the Vandy 2Wq. Have been using mine with Magneplanar 1.6QRs in a two channel only system for the last nine years and am completely happy with every aspect of it's performance. Make sure you understand what you're getting into with the 2Wq as it uses a somewhat unconventional but extremely effective hookup method.
