D2608/9130 vs. SB29RDC

[edlafontaine]

A project I have in mind comes down to selecting between tweeters to be mated with SS 18W8531G's.

The candidates are the SB29RDC:

and the D2608/9130:

What say ye?

Re: D2608/9130 vs. SB29RDC

I vote for the SB29RDC because of good low end response and high spl. I assume nobody would buy that scan woofer if they could not afford a 4 ohm amp.

I would choose the Scan - only because I have always wanted to try that tweeter. Many who's opinions I respect gave it high marks when it was under the Peerless name. I can't imagine the new name on the sticker changing it's sound, at least I hope not.

The only example that I know of comparing those two tweeters to each other in an otherwise same speaker system the owner prefered the RS28F to either of them.

Re: D2608/9130 vs. SB29RDC

I'd go with the dimple dome. It's a little cleaner down low with respect to high order distortion and of course, it's more reasonably priced. Both are excellent products but all things considered, it's no contest in favor of the SB.

Re: D2608/9130 vs. SB29RDC

Neither one of those is one of my favorite tweeters. A lot of people like them both, but I find both lacking in areas sonically. If it has to be one of those, I'd use the HDS too.

Hmmmmm..... I have the HDS, the SB29, and the RS28 all in speakers here with me now.

As for the HDS, you should see the measurements I have taken of it. If it is lacking something, I am at a loss to tell you what it is; it both measures and sounds superb to me. I can't see it lacking in anything sonically in my application. And, I can't see where I would gain much by spending two or three times as much for a "high end" tweeter over it either.

Remember, implementation means a lot.

I have not performed the same measurements with the SB29 (yet), but in my Piccolo I am very happy with the frequency response, and the detail I am able to extract with this tweeter. It is the better of the two for a low crossover point. The HDS clearly has better off-axis characteristics. Take your pick.

The HDS is built better and looks nicer IMO.

Re: D2608/9130 vs. SB29RDC

I like the RS28, never said I didn't. Mind you when I reference a driver, I'm not referring to it as a person used it, but as a whole.

Most of the time, I find the HDS is fine. It just does nothing for me that makes me stand up and say "I want to use it". It has no emotion to me, nor does it move me. It is just 'fine'. (The RS moves me.)

The SB's all seem to sound 'dead' on top (except in your Piccolos). I find them to overall be somewhat muted/dark in tonality on a general basis.

I never said he had to spend a lot more money either. You know I'm thrifty as a builder, so I wouldn't either. I definitely agree the HDS looks nicer.

I think the Ushers would also be suitable, and I really like what I've heard from the 9950's.

As I recall, Ed got one of those at last years' Tent Sale, so that I would also see as a possibility.

I think the Neo3 would work, and I've never seen that combo before.

Re: D2608/9130 vs. SB29RDC

zeek & Wolf, I do have singles of the 2905/9500 & 9700. I could pair one or the other. Those could be options. The 9900 is out of budget, atm.

zeek, I have pairs of the AC GS2i & G3, so I won't be getting any PDR's soon.

Back to the plan; my thought is to remove the tweeter from the faceplate and backmount it on the baffle. I would increase the depth of the waveguide some...I want to play with the aesthetics of this. I think there may be found a "balance" between a mega waveguide and a shallow guide. The manufacturer's face plates only hint at it. The Seas DXT (H1499) is the direction I'm thinking...in wood. Heck, at ~$55 it IS an option. Jed put a H1212 behind the H1499 faceplate with good results. It should also improve the efficiency a little. I think this would reduce distortion.

The crossover point under consideration atm is ~1600 Hz.

Jeff et al, can you "inform" me of the value of off-axis response? I plan to use these as front mains...a flat screen between them, 2 subs in a "distributed" arrangement. Music will be enjoyed either from the "sweet spot" or from any number of locations in adjoining kitchen & dining room.

I value all your input

Re: D2608/9130 vs. SB29RDC

Is this going in the T-line that you were kind enough to share the designed with me a little while ago?

I have a friend the reminds me that I better get started building it!

Re: D2608/9130 vs. SB29RDC

A MLQW box could be an option. However, I feel the need to be space conscious for these...out of respect for my wife's expressed sensibilities :D and having 2 subs in the same room.

One of the sub's was quietly on display @ MWAF...brought along as show and tell. Both will use ACI SV10's. One ported, one sealed.

That thing was gorgeous, and it was a shame I didn't get to hear it.

Nicely done, bud!

Re: D2608/9130 vs. SB29RDC

Ed: I assume you've seen the waveguide used on the latest version of the Elsinore? It designed for the HDS.

When used with a waveguide, I've heard of people using the XT25TG30 quite low - I think one guy even said 500 Hz :O *eek*

I'd love to see a community developed waveguide perfected for use w/the XT25 (and either the same, or slightly diff. for RS28).

I wonder how similar the SS 9500 and the RS28F are. I believe Wolf has used faceplates from one on the other?
