I looked at Zalytrons website and didn't see any vintage seas listed, at least none in the $15-20 range.


try here

I'd give you the Seas URL for their vintage drivers, but they just updated their site, and my bookmark no longer works... but I'm sure they are still there.

Zaph tested the M165x and seemed to think it was o.k. Is the M130 or 130x any different? It seems to be priced very well. Even if it is an o.k. driver would seem to be hard to beat at the price. Though I need something fairly easy to implement and know nothing about it. I am afraid the Peerless driver(at least the exclusive)might be a challenge to implement due to the peak at 450hz. maybe not as big a deal as I think. thanks

Yeah, the high 3rd order harmonic at 450 Hz is the only drawback of the 5.25" Exclusive. Otherwise, it is the only driver under $100 in the group that can be comparable to the ScanSpeak driver w.r.t. distortions. How audible is the third order harmonic? It should be barely audible. Only one or two notes (A440 key) in music will be affected by this peak.

The GR M130 or M130X should be a good choice, too. The X version has Adire's patented XBL^2 motor which increases the woofer's linear excursion, thus improving its low-end performance. But I expect its overall nonlinear distortions are a bit higher than the Peerless HDS drivers'. Peerless HDS nomex or poly has a very good cost-to-performance ratio IMO.

Hi Jay,
I must say the Peerless drivers do look nice, and have read nothing but good things about their performance. do you think they would perform well in a TL. Is one(Peerless/Gr-Research) better suited than the other. thanks

Kris

I don't know much about TL design. But AFAIK there's no reason for either Peerless drivers or M130 being inappropriate for a TL.

Seas drivers are definitely a step up from HiVi and Tang Band in terms of both quality and consistency. When it comes to HiVi I would not trust the driver that you receive to match the specification of the driver listed in the documentation.

Seas are high consistency, high value drivers and the specs are listed warts and all.

HiVi are much lower consistency and the listed specifications are often idealized.

Parts Express sometimes makes measurements of their products, there are a much more reliable source of measurement when it comes to drivers like HiVi, tang band, Dayton etc. that the manufacturer's own info sheet.
