jbl lsr305 vs. psb b4

I was looking at upgrading my computer speakers. This what I currently have.
http://www.zzounds.com/item--MDOLX4
Great sub, not so great sats. Are these two in the same class or or they more or less a matter of taste? One thing to note...using a passive speaker means xover is at 140hz. No way to adjust that. If active, I'll get 140-40hz from the sub and any additional sub 140hz from the active speaker as well. Not sure it that will effect anything.

I wouldn't rely on that sub to power speakers, you would better off with active speakers in my opinion. However you might have to split your output from the computer to send it to both the speakers and sub. I personally would prioritize upgrading that sub to something with line-level inputs and outputs, and a crossover.

Agreed.

Crutchfield's current price of $179 seems a really good deal on the PSB Image B4s. But you should buy them with the intention of getting them their own amp.

Admittedly quirky, the sub has 1/4" trs inputs and a fixed 140hz crossover and sounds really good. The only issue with sticking with passive would be only 27w of power and that high crossover. At this point, neither one if those is an issue. I was trying to stick to a small 3 or 4" speaker for size and no need for the lower frequencys. But at $225 on sale, i like the jbl. I've always wanted to hear some psbs as well though. So $200 for a set of those interests me. That's why i was looking for how they might compare. There is also no need to split a signal. If passive, the sub xover splits at 140hz. If active, i use a native instruments audio interface with 4 outs. So i can assign a third output and send to the sub.

Are the LSR305s currently on sale for $225 a pair somewhere? I thought they were running $270 to $300.

So lsr at $225 beats out b4 at $200 you think? I've never heard either one.

I have no idea which will sound better. I think you'll have a lot of problems finding someone who has heard both. I would bet on the LSR305 to have better low midbass output because of the larger driver. But PSB makes some very nice speakers.

Best bet is to order both sets, then return one

Funny you mention that. My original plan was to start collecting bookshelves in the $300 range. Purpose being to find out what speakers i like when i replace my klipschs. My wife hates them. She has trouble with menere's/ear ringing and harshness/sibilance hurts her ears. That's the only thing holding me back from the lsr's....there's really no future for them replacing my main system.

PSBs would definitely be a nice change from Klipsch in that regard.

I have no place to use them, but I'm really itching to try those JBL's.

Me too. That's why I asked about the price. But I really don't need them at all.

I don't find sensitivity to be nearly as important as it looks on paper. My Pioneer BS-22's are rated at like 86 or so, and they have no problem filling a room even with fairly small amplifiers.

If that is your thinking - then PSB B4 will not work with its low sensitivity.

Most bookshelf speakers in the real world, average 86-88 db sensitivity -
also the impedance swing plays a part - more to it, than just sensitivity.

Well, made my decision. Went to figure out where to order a pair of b4's, and lucky me, Crutchfield had an open box b5 for $212. So it's a done deal. Psb b5 for $212.

Their location now will be at the computer, but rest assured I'll try them in the living room(20x14). They should fit right on top of klipschs for temporary stand. Probably cross them over at 60hz just to see what they can do.

That may be a little optimistic, as their bass does begin to roll off early - however you can try.

Exactly....xover at 60hz as a precaution. No need for them to see 40hz if they won't even play it. About that crown amp(xls 1500). Should i turn the gain down a little or just make sure to not keep the volume in check?

I would always start modest/moderate - to get the feel of the speaker - then go from there

New idea....forgot i have an adcom 2535 in storage. Kind of sad huh, lol? Forget you have a 4 channel amp. I was bridging 2 channels for 200w to the center. One of the binding posts broke and guess which channel it was on? Yep, one of the ones i needed to bridge. I never got it fixed and didn't need it for only 60w, so that's how it got decommissioned. Anyway, i could go out from the audio interface x3 and still use the sub. Still wouldn't have a crossover so the sub would be playing up tp 140hz and the b5's full range. But atleast there wouldn't be any impedance or clipping issues. I think 60w nearfield would rock.

60 watts should definitely be enough nearfield for the PSBs
